After Tan Li left, Rose was the only one left in the research room.

The first product developed by himself is about to come out, and Ross's excitement can't be stopped.

It was planned to take an eight-hour break from work, and now Ross had to break that rule.

Rose was so immersed in his work that he almost lost his mind, and he could barely feel the passage of time.

Ross shoveled the extremely sticky soil from Tan Li and the high-temperature electric furnace with a shovel, pinched the mud with his hands, and made a mud ditch five meters long and no more than twenty centimeters wide.

After smoothing the mud with a mason's tool, Ross mixed cement with asbestos, brushed a layer of cement on the outside of these mud trenches, and a simple cooling tank began to take shape.

Ross continued to be busy, connecting the leaky shower heads for bathing to the water pipes and erecting them on the drain, and the construction of the cooling tank was basically successful.

Ross opened the control valve of the high-temperature electric furnace, and a stream of arm-thick red molten steel flowed out of the furnace, and when he pressed the switch, more than 30 leaky nozzles were poured on the molten steel, making a sizzling sound and green smoke rising. After being cooled, the molten steel quickly cools down, turning from red to black.

Ross's plan is to cool the molten steel to a liquid state, and then let the liquid steel enter the 3D printer, where the heating element of the heating rod is printed.

But the first time it seemed to fail, after the molten steel passed through the cooling tank, because the water sprayed too much, it solidified at once, and it only flowed more than two meters away, and then it solidified and turned into iron.

"Damn! The water is sprayed too much, so you have to reduce the amount of water you use and not cool down too quickly. ”

Ross ran to the computer, calculated it, and then came back, turning off 8 of the sprinklers and using only 22 to cool down.

Start the high-temperature furnace again, the molten steel flows out again, 22 nozzles, evenly spray water, sprinkled on the molten steel, this time the effect is good, the molten steel is not cooled so fast, it flows directly into the 3D printer.

"Cool! It works well. ”

Ross was excited, but found another problem, some molten steel got stuck in the cooling tank, and if it accumulated too much in the long run, the cooling tank would be blocked.

"You have to smear the cooling tank with some industrial lubricating oil to reduce clogging."

"I'm afraid it won't work with oil...... Although the temperature of molten steel has decreased, it is still more than 1500 degrees, and ordinary oil will not be able to stand it. ”

"How to make a cold sink that is lubricated and not lost by high temperatures!"

"I can only buy some more glass wool, which can withstand 3,000 degrees of heat and be as smooth as glass, which is a good choice."

Ross found a solution, and ran to the computer excitedly, searched the building materials market phone, and called a store that sold glass wool and asked for home delivery.

Half an hour later, dozens of kilograms of glass wool were delivered to the villa, and after Ross paid for it, he returned to the research room with the materials.

After spending half an hour gluing the glass wool into the cooling sink, Rose rubbed his sleepy eyes and continued to work.

When the furnace is turned on again, the molten steel flows along the mirror-smooth cold water tank, and the water sprayed out by the nozzle is just enough to cool the temperature of the steel to about 1,600 degrees, and at this temperature, the steel is still liquid and can still flow.

The liquid molten steel flows diagonally into the funnel above the 3D printer along the cooling tank.

Ross started the 3D printer, and under the control of the program, the gradually hardening molten steel was squeezed out by the printer like squeezing toothpaste, forming a cylinder the size of a toothpick, which is the basic heating rod.

On the other side of the 3D printer, there is a plug with copper wires in it. After this plug inserts the copper wire into the heating element that has not completely hardened, the cutter on the 3D printer automatically cuts off the heating element that has not completely hardened and falls into the bucket.

The bucket is filled with cold water, and the heating rod falls into the cold water, and after a second cooling, the temperature drops to several hundred degrees.

Wearing gloves, Rose fished out the heating rod, which had been completely cooled, from the water.

The main body of this heating rod is well manufactured, and its material is made of mixed metal materials, which can heat up quickly and cool quickly. The copper wire inserted in the middle, as long as it is connected to the power supply, can make the heating rod produce high temperature.

The manufacturing process of the whole heating element is actually very simple, the material enters the high-temperature furnace, becomes steel, and then the molten steel passes through the cooling tank, and after cooling, it becomes liquid molten steel, and enters the 3D printer, the 3D printer made of composite materials will not be damaged by the high temperature of less than 2000 degrees, and it can complete three working steps under the control of the computer.

In the first step, the molten steel is squeezed out like toothpaste to make the rod body of the hot rod, and the second step is to insert the copper wire as a battery cell, which can be used to energize. The third step, the alloy cutter, cut off the rod body that is not very hard. After a few steps, the heating rod was successfully manufactured.

Turning off all the machines, Ross took the heating rod from the bucket to the instrument for testing.

After the power is turned on, the heating rod heats up quickly, and the effect meets Ross's expectations. The lowest technical heating element has been completed.

"My heart began to panic again...... Depend on! I was going to make a heating rod overnight, but it seems that I have to rest. ”

Heart disease is like a life-threatening charm, urging Rose to rest, for the sake of his life, Rose can only reluctantly stop the work at hand. Turn off all the machines and go back to your room to sleep.

The next morning, after six hours of sleep, Rose had recovered his spirits, and when his heart was not flustered, he was no different from usual.

Ross drilled into the lab again and began to make a power supply unit for the heating rods.

After the nano-titanium oxide and nano-silicon oxide are completely crushed with a press, the two materials are mixed into a tighter granule.

Ross poured two materials into the 3D printer, replaced the computer program, and replaced the printer's ports and spouts, and the two materials became soft as mud again under the action of chemicals.

The 3D printer, like a drawing, extrudes the two materials into a one-centimeter-long, toothpick-sized round battery, and the other port inserts a piezoelectric material the size of a grain of rice into the battery that is still completely solidified.

A simple, high-tech power supply unit has been successfully manufactured.

Rose excitedly picked up the miniature power supply unit and went to test it again.

This miniature power supply device uses two nanomaterials to greatly increase the capacity and discharge capacity.

The piezo appliance the size of a grain of rice inside is made of piezoelectric ceramics and works on the same principle as ordinary plastic lighters. As long as the lighter is pressed, the voltage motor inside can convert mechanical energy and electrical energy to each other. However, the plastic lighter uses electronics, and the electricity in it is very scarce, while Ross uses a miniature nanomaterial battery, which has a capacity countless times that of a lighter.

I can't wait to make a successful micro power supply device, like a screw, screwed on the heating element, and a successful heating rod has been manufactured.

After Ross plugged the heating rod into a special charger, it was already charged to 0.3 kilowatt-hours in about three minutes.

Ross was very excited, picked up the heating rod, and after pressing the button at the end of the power supply unit, with a click, the current was released, and the heat of the heating rod had already generated a high temperature. Rose couldn't wait to toss the heating rod into a glass bottle.

In less than a minute, the water in the glass bottle has already come out of the hot gas, and the heating rod has heated all the cold water.

"It's a success, Lao Tzu has succeeded."

Rose was so excited that she couldn't help but scream.

"I have to show Sister Li the benefits of my things."

After making a few heating rods, Ross turned off all the machines, carried the heating rods, and went downstairs happily.
