With the new equipment entering the factory, Duan Yun finally began to retrofit the newly introduced carburizing furnace.

Duan Yun is still very cautious about the modification of this carburizing furnace, because it involves him mastering the key core technology of a factory, so he must do it himself.

In fact, the domestic carburizing technology in this era is not mature, and the uniformity of the carburizing of the workpiece is not high, which only solves a problem, and the performance is very different from the mature vacuum carburizing furnace in the future.

This earliest domestic pit carburizing furnace is a kind of gas carburizing furnace, the working principle is to load the workpiece into a sealed carburizing furnace, through the gas infiltrating agent, such as methane acetylene, etc., or liquid infiltrating agent, such as kerosene alcohol benzene, etc., at high temperature to decompose activated carbon atoms, infiltrate the surface of the workpiece, to obtain a high carbon surface into a carburizing operation process.

This time, the city bureau applied for two carburizing furnaces for Duan Yun's factory, and on the first day of the equipment, Duan Yun went to the workshop to study the two equipment.

Compared with the carburizing furnace equipment used in his own factory in later generations, the performance of this domestic carburizing furnace is very backward, the energy consumption is large, and the carburizing effect is not good.

Before Duan Yun entered the factory, Duan Yun Zhiping's product drawings had already begun to study a set of modification plans.

For new equipment entering the factory, general leaders do not dare to drastically transform the equipment, especially the more advanced equipment in China, but Duan Yun dares to do this, because he has a deep technical background and has the confidence to do so.

He has three goals for the modification of carburizing furnace equipment, the first is to reduce energy consumption, the second is to improve the performance of the production process, and the last is to modify the furnace with integrated circuit digital control.

And just when Duan Yun began to transform the new equipment, a nationwide crackdown on criminal offenses officially began.

The Red Star Gear Factory was soon plastered with all kinds of slogans to crack down.

Propaganda slogans such as "Cracking down on criminal activities", "Improving the social security prevention and control system, and strengthening the comprehensive management of social security", "Cracking down on illegal and criminal activities in accordance with the law, ensuring that the people live and work in peace and contentment", "In-depth development of the special struggle against two robberies and one theft crimes", and other propaganda slogans and big-character posters are pasted all over the streets and alleys of the Red Star Gear Factory, so that the workers of the entire factory area feel a special atmosphere.

In fact, before this crackdown, the social security situation in Daxing had already begun to deteriorate, and when Duan Yun drove Cheng Qingyan to the night before that, he saw on the road that there were young social gangs fighting and fighting, and the methods were very fierce and bloody, which was unimaginable before.

Before 1979, the number of criminal cases in Daxing was less than 100, and this situation continued until 82 years ago, when there were not many criminal cases in the city, but since 1982, the annual program has been more than 100 or even more.

Especially in 1983, that is, this year, the social security situation in Daxing has become very severe, the main reason is also very simple, Daxing is an energy city, after the reform and opening up, the city's economy has fully recovered, the income gap has widened rapidly, and some people are psychologically unbalanced.

For example, on the afternoon of June 19, 1983, a criminal gang headed by Wang Zhengzheng, a released prisoner, led six people to rob property near the Yungang mine, and armed with kitchen knives in just a few days, robbed many times, and gang-raped women.

On July 27 this year, that is, more than half a month ago, the "Daxing Daily" published such a piece of news, saying that Liu Chengjun, a labor camp escapee, and four criminals, including Li Zhiqiang, a labor re-education detainee, broke into the Celadon Kiln Restaurant, beat four customers who were eating with sticks, and forced them to kneel on the ground.

Although this incident did not cause serious casualties, it still had a considerable psychological shock to ordinary citizens.

In addition, there is another incident that caused a sensation in Daxing, a woman named Liu Yuemei, instigated her son Zhao Yong, and entangled a group of people in the Silaogou Mine and Yanya Mine areas, and committed 19 burglaries and crimes, which caused a great shock in the mining area, and the masses were panicked and did not return home at night, seriously affecting the production of the mining area and the lives of the workers.

As public order deteriorated, even prostitution activities, which had disappeared in the past, were revived, and in June and July of this year, some women solicited customers at the bus station outside the West Gate and in front of the Hongqi shopping mall every day.

After the central authorities issued the strategic policy of resolutely cracking down on criminal offenses in one net, the Shanxi Provincial Party Committee made unified arrangements, and Daxing City launched a large-scale anti-crime operation in the early morning of 15 August, that is, the day before yesterday, which lasted for several days and yielded fruitful results.

In this operation, the Daxing City Public Security Bureau arrested a total of 897 criminals of various kinds, including 268 sporadically captured before the operation to prevent escape, which is quite a staggering number.

Duan Yun had known about the history of the Strike Hard before, but now that he was in this era, the impact of the Strike him was very huge.

Every day at noon and in the evening, the buildings on both sides of the road are plastered with various slogans and big-character posters, and the billboards next to the factory clubs are filled with all kinds of propaganda materials on the Strike Hard Campaign, and the names of some criminals and the relevant verdicts are published.

In addition, factories have also begun to organize employees to participate in some public judgment meetings.

The theater street and the lighting stadium in the factory area are the main places of public trial, and the green-skinned liberation trucks are pulling the prisoners who have been tied up with flowers, and these prisoners have signs on their chests, writing their names and the crimes they have committed.

At least one or two thousand people will participate in each public judgment meeting, and the stage is neat and tidy, with rows and rows of public security and criminals, while the audience is crowded, surrounded by armed policemen in military uniforms and armed with guns and ammunition, and the atmosphere is solemn and noisy.

After the public judgment conference, these prisoners who have been sentenced to death will be pulled directly to the execution ground by car, and a bullet will bring their lives to an end.

Duan Yun has been very busy with the production tasks in the factory recently, including himself, in order to modify the new equipment, he has entered the stage of forgetting to sleep and eat, and at this time, the superiors require the workers in their factory to participate in the public judgment meeting, and it is a hard and fast rule, the production tasks of the front-line workers are very urgent, so Duan Yun simply sent all the workers in the agency out, he can't let this crackdown campaign destroy his production plan.
