Although Zhao Limin missed the CET-4 test by ten points, he still understood this simple word.

"Shh He and Jiang Xilin silenced everyone at the same time.

Wisney bent over and adjusted the four anchor bolts one by one.

Seeing that the level showed that the bed was already horizontal, Hawke shouted repeatedly, "OK! ok！ ”

“no，no，no！” Jiang Lin pointed to the level and said, "The bed is not level enough, and there is a deviation of the wire!" ”

"It's just a slight deviation, it's completely negligible!" Hawke shrugged his shoulders and acted disapprovingly. Indeed, the French have been pursuing freedom and romance all their lives, strictly abiding by the machine tool installation system, and using a protractor to calculate the number of turns of the screws little by little, which is a great torture for them.

Jiang Lin wanted to say something, but Zhao Limin stopped him, "Jiang Lin, now is not the time to pursue precision, just install it!" ”

Two reporters stood on the sidelines, scratching out the paper, "Then, the four anchor bolts were locked evenly." ”

This kind of modern old-fashioned machine tool is very different from the machine tool of later generations, and Zhao Limin specially arranged two recorders to record the whole process of installation of the machine tool. This is to learn more about the installation process of old British machine tools, and to decide how to dismantle, remodel, and install them in the future.

Both Hawker and Wisney are experienced installers and know the structure of the lathe inside out. The two of them cooperated with each other, and the workbench was installed and adjusted in three clicks and two clicks, and then the bearings were installed.

I saw Hawk pick up the bearing, wipe it with oiled paper, and start the installation.

The apprentices all shook their heads in their hearts, and the booklet made it clear that the bearings must be cleaned with gasoline before installation, otherwise the residual trace oil stain will affect the accuracy of the machine tool. These young men don't know that there is no concept of gasoline in Europe and the United States now.

Zhao Limin felt that there was no need to look at it anymore, remembering that the forging workshop was still installing a steam hammer, and he had to go to the glass factory at ten o'clock, he turned around and walked out of the workshop.

The secretary then chased after him, "Factory director, the machine bed and workbench are not level enough, and the bearings are also deviated. According to this installation method of the British card, the accuracy of the lathe is too far away. ”

Zhao Limin laughed, "After the Ying card is gone, we will dismantle the machine tool in eight pieces, change the collective transmission to a separate steam engine transmission, improve the cutting efficiency, and modify the thread structure of the caring..."

This secretary has been following Zhao Limin for half a year, and he has read several pamphlets on machinery. He was a little puzzled, "Why should the threaded structure be transformed?" ”

"The measurement of our machine tools is unified with the metric system, and the British card lathe can only turn the inch thread, if it is changed to turn the metric thread, it does not affect the product accuracy and production efficiency, then the thread structure must be modified."

At ten o'clock in the morning, an official carriage came to the machinery factory along the way, and Qian Shuiting and Xiao Bailang were both sitting in the car.

Zhao Limin got into the carriage and talked about his feelings with the two CEOs, Qian and Xiao. He talked about the problem of standard parts from the two different standards of metric system and imperial system.

In the future, the number of European and American machinery will be more and more, and the team should go all out to promote standard parts now.

The so-called standard parts refer to the structure, size, drawing, marking and other aspects have been completely standardized, and are produced by professional factories commonly used parts (parts), such as threaded parts, keys, pins, rolling bearings, etc.

I remember that a few days ago, I also instructed an apprentice to turn screws. Xiao Bailang sighed, "Qian Dong, speaking of which, the machinery industry has manufactured a large number of equipment for other industrial sectors, but its own construction is a little backward. ”

Qian Shuiting touched his cheeks thoughtfully, "What does Mr. Xiao mean?" ”

"I think that the machinery industry must immediately manufacture a number of special machine tools and equipment, as soon as possible to launch standard parts factory, mold factory, foundry, bearing chain factory, tool factory ......, as soon as possible to complete the equipment matching."

"Agree with you!"

After listening to Xiao Bailang's explanation, Qian Shuiting smiled heartily, "It's not easy to train an excellent technician, you can't let them start the lathe and cut screws and screws one by one..., isn't this a waste of talent!" ”

About six kilometers to the east of the machinery factory is a major bend in the Keelung River, where the flow of the Keelung River turns from due west to due north, and the Taipei Glass Factory is at this big bend.

The glass factory belongs to the building materials department of Taipei Industrial Group, which is basically built in accordance with the design drawings of the glass factory in the late eighties of the twentieth century, with a factory land of more than 10,000 square meters, a building area of 4,000 square meters, and a yard area of 400 square meters.

The processing process of the raw material workshop adopts a multi-system process.

Each raw material has a set of crushing, crushing, sieving system, and finally mixed into a batch in the mixing machine room, through the inclined belt conveyor, transported to the glass production workshop kiln head silo, and then put into the glass furnace kiln by the blanket feeder.

The glass production workshop is equipped with a set of small float glass production lines, which Xiao Bailang and Chen Wangshu, the director of the glass factory, led people to tinker for several months according to the technical drawings.

Float glass production lines do not require the manufacture and installation of bulky sand grading and mechanical polishing equipment, and are relatively fast, cost-effective and of good quality. Chen Wangshu participated in the discussion of crossing, and when designing the production technology, he took float glass as the main means of production.

In the glass production workshop, Ma Guihua and Chen Wangshu are leading workers to inspect machinery and equipment and prepare for the operation of the float glass production line.

Seeing Qian Shuiting, Xiao Bailang and others walking into the workshop, Ma Guihua and Chen Wangshu hurriedly greeted them.

Qian Shuiting waved his hand again and again, "You guys are busy first, let's take a look!" ”

Chen Wangshu said with a smile, "Mr. Qian, Mr. Xiao, and Director Zhao are in charge in person, and I don't dare to have problems with this production line!" ”

Qian Shuiting smiled and waved his hand, "The Baath Party pays attention to materialism, so you should go and get busy!" ”

"The gas transmission pipeline and valve are intact and leak-free, and the adjustment mechanism is normal."

"The auxiliary fan and motor of the kiln are in normal condition."

"The observation hole of the kiln is in good condition, and the monitoring measuring instrument is in normal condition."

……

Ma Guihua kept ticking the safety record sheet while checking.

After a circle, Ma Guihua's face was full of joy, "The glass melting kiln, tin tank, and annealing kiln have been ignited since yesterday afternoon, and everything is working normally in the baking kiln so far!" ”

The float glass production line is mainly divided into three parts: glass melting kiln, tin bath and annealing kiln. The kiln is mainly to remove the water vapor of refractory bricks and other parts in the kiln, and at the same time, it can also check the status of mechanical equipment.

The float glass melting furnace built by Chen Wangshu is a cross-fire pool melting furnace with two regenerators. The melting zone of the special high-temperature resistant refractory brick masonry is 20 square meters, the clarification zone is 12 meters, and the outer frame is an iron structure. The mechanical power system uses a steam engine, and the fuel is the hot gas produced by the gas generator, which can smelt 50 tons of molten glass every day and night, and has a designed annual production capacity of 25W standard boxes of flat glass.

The 10-metre-long tin bath holds 4 tonnes of molten tin and is the most critical thermal equipment for float glass production. Chen Wangshu and Xiao Bailang directly used iron shells, refractory materials, and heating wires to build a sealed, wide at the front, narrow at the back, and shrunk in the middle.

Because the tin bath is highly oxidized at high temperatures, the tin bath space is filled with a nitrogen-hydrogen mixture and a slight positive pressure is maintained. At the same time, the tin bath cannot be heated with ordinary fuel, but only with electricity.

"This furnace and tin trough are too small!" Chen Wangshu was a little dissatisfied, "According to my temperament, at least a large melting furnace with a length of 70 meters and a width of 25 meters, and a large tin bath with a length of 60 meters, can produce 900 tons of flat glass per day." ”

"That's going to take hundreds of tons of steel, hundreds of tons of tin ingots." Xiao Bailang shook his head, "There is no guarantee at this stage. ”

The whole furnace and tin bath are completely supported by the supporting steel structure at the bottom, and the existing steel and pure tin are also smelted out of the crucible little by little, which cannot meet the large float production line.

"In the second half of the year! In the second half of the year, a large-scale float production line can be started"

Qian Shuiting is also itchy, to be able to produce flat glass in large quantities, it means that the money is rolling in, and the life of the household department is not too easy!

At one o'clock in the afternoon, the float production line officially began trial operation.

The batch is fed into a hot melting kiln, and after more than ten minutes, it is heated to more than 1,200 degrees.

The hot gas lance spewed flames, and the temperature of the melting kiln continued to rise. The heat wave continued to pour through the thick walls of the kiln.

Although there is a water curtain device to block the invasion of high temperatures, the workers working in front of the kiln still can't stop wiping the sweat beads on their foreheads and desperately drinking cool drinks......

"1400 degrees!" Chen Wangshu's eldest apprentice held a WGGZ optical pyrometer and continuously observed the surface temperature of the molten glass through the observation hole.

The WGGZ optical pyrometer is a kind of filament-concealed optical pyrometer. This type of pyrometer is easy to measure, and it is not easy to be damaged, and it is easy to maintain.

Under the action of high temperature, feldspar, dolomite, limestone, miscanthus salt, and soda ash are completely dissolved and turn into red liquid glass. At this time, the liquid glass contains a large amount of air bubbles, so it appears opaque.

The molten glass flows from the melting pool into the clarifier, where the temperature continues to rise to over 1,600 degrees Celsius. The reddish solution boiled, and clumps of bubbles floated to the surface, exhaling a fiery breath.

Xiao Bailang wanted to try the feeling of high temperature, he just stretched his head out of the water curtain, and the heat radiation was like thousands of steel needles projected, stinging the skin and stinging the eyes. Returning behind the water curtain, Xiao Bailang was a little lucky, fortunately, the hula flowing water intercepted the scorching high temperature.

Seeing the molten glass flowing from the clarifier into the cooling area, Chen Wangshu's second apprentice immediately operated the machinery outside the water curtain. An iron rod with a hook lowered from above the cooling zone and slowly reached into the molten glass. Driven by power, the iron rod began to stir the molten glass continuously.

The molten glass entering the cooling section needs to be further clarified, homogenized and cooled to meet the requirements of molten glass molding.

Qian Shuiting knew that this was to completely remove the bubbles by stirring. Qian Shuiting has read several books and knows that smelting glass is mainly to solve the two major technical difficulties of decolorization (solving transparency) and clarifying (removing air bubbles).

From the observation hole, peeking into the red, slimy glass slurry rippling in the cooling pool, he asked Ma Guihua, "Is there no problem with transparency?" ”

Ma Guihua, deputy general manager of Taigong, who is in charge of the building materials department, said with a smile, "We are a standard formula, and there will be no problem with transparency." As long as the bubbles are removed, it's done. ”

The iron rod kept stirring, and after ten minutes, all the streaks and stones in the liquid glass melted, the bubbles all disappeared, and the temperature of the liquid glass gradually decreased.

Looking at the red liquid glass, Qian Shuiting suddenly opened his mind, and he asked Chen Wangshu, "Can you blow a light bulb?" ”
