The steel workers in this city promote the spirit of self-reliance and mutual cooperation

This year, there are over 400 new types of steel produced.

Since the liberation, the metallurgical industry in this city has developed rapidly, from being unable to produce steel to being able to produce over a thousand types of steel. Many high-quality steels and alloy steels have been widely used in the production of machinery, chemistry, and daily necessities industries.

Workers in Beijing's metallurgical industry should carry forward the revolutionary spirit of self-reliance and implement the policy of building a country through diligence and thrift. At present, the local metallurgical industry in Beijing can produce over a thousand types of steel. Among them, there are over 400 types of newly produced steel this year alone. These steels are high-quality new varieties urgently needed in industrial construction.

Beijing is a steel city. In the past, Shijingshan Iron and Steel Plant used to produce only a small amount of simple steel, and the only professional steel rolling mill was Deshengmen Rolling Mill. At that time, even flat steel and Yuan steel for making pliers and machine feet in Beijing had to rely on supplies from other places. Now, not only can this city produce steel, but it can also produce many high-quality steels. Many silicon steel sheets, cold-rolled steel strips, and other materials that could not be produced in the past, such as thin plates used for enamel basins and cups, can meet the needs of industrial production in terms of quality; High temperature and high-pressure seamless steel pipes used for manufacturing boilers, as well as steel for producing important machine products such as turbine blades, have reached a certain level and can better meet the technical requirements of national construction.

When workers in the metallurgical industry built factories on the basis of poverty, they utilized national investment to construct and expand a number of factories; At the same time, adhering to the principles of simplicity and frugality in running a business, the original factory buildings and equipment were utilized and renovated. Many factories in the Beijing metallurgical industry system have grown up by renovating old houses without glass windows, and the company offices are now old cowsheds. Now, the "Red May" steel company has entered the ranks of fully mechanized rolling equipment, with over 400 varieties of steel. The utilization rate and technical operation level of blast furnaces have maintained advanced levels. The silicon steel sheet produced by Beijing Rolling Mill is an electrical material with a wide range of applications. In the past, China could not produce it and relied entirely on imports. Now, not only can this factory produce, but the quality is also very good.

The workers in the metallurgical industry system, relying on their own strength, have achieved one innovation after another in production, continuously increasing the variety of steel. The workers of the "Seven Brothers" group in Beijing Steel Plant who produce electric furnace steel have been vigorously promoting technological innovation and revolution in recent years to improve production efficiency. Currently, they are able to produce many advanced alloy steels that are urgently needed in China. In the past, the West imposed a technological blockade on China regarding this type of steel. After more than two years of hard work and learning from advanced foreign experiences, as well as joint research and experimentation by technical personnel and workers, the employees finally mastered the technology and put it into production. The high-temperature and high-pressure seamless steel pipes produced by local steel mills used to rely entirely on imports. Now, with just over 10 million yuan of national investment, they have designed and built a factory equipped with large-scale gas generators, coke ovens, and other equipment. It only took more than 1000 working days to start production.

This year, in addition to relying on their own technical strength, various metallurgical factories have also adopted the method of mutual support and assistance between factories in developing steel varieties in order to supplement equipment and technological deficiencies. Many products are the result of great collaboration. For example, the silicon steel produced by the steel rolling mill is not only qualified, but with the help of Beijing Iron and Steel Institute, the product quality has also been improved. During the trial production of a high-power industrial frequency furnace, workers and technicians at Beijing Steel Plant used a method of forcefully inserting a long steel ingot from the narrow opening of the furnace in order to master the production technology of high-temperature and high-pressure boiler tubes. After repeated experiments, they finally mastered the technology.
