The Chinese foundry industry is in the growth stage and has good development prospects; large foreign foundry companies have increased their investment in China and increased their investment in China through direct investment and mergers and acquisitions. On the one hand, it has improved the overall level of my country’s foundry industry, and on the other hand, it has also increased the degree of competition in the domestic market.
The level of foundry mechanization and mold accuracy, performance, compatibility, and reliability are much lower than those of developed countries. Many key parts and molds need to be imported. In my country, the foundry industry is in the growth stage and has a good development prospect; large foreign foundry companies have increased their investment in China, increasing their investment in China through direct investment and mergers and acquisitions. On the one hand, it has improved the overall level of my country’s foundry industry, and on the other hand, it has also increased the degree of competition in the domestic market.
The “2018-2023 China Steel Casting Industry Market Demand and Investment Planning Analysis Report” issued by the Qianzhan Industry Research Institute pointed out that the output of my country’s steel castings is concentrated in East China and Central China, with obvious regional concentration, and other regions are also actively tackling key problems. Steel casting production. In December 2017, the Ministry of Industry and Information Technology and the China Federation of Industrial Economics jointly announced the list of the second batch of manufacturing single champion companies and single champion products. The shared steel heavy-duty gas turbine steel casting products recommended by Yinchuan Economic Development Zone were successfully awarded The national single championship product marked Ningxia’s zero breakthrough in the national manufacturing single championship product.
The steel casting industry has a wide range of applications. Especially under the conditions that the future development of automobiles, construction machinery, agricultural machinery, and power equipment is relatively large, the state has also issued relevant policies to support it. Therefore, Qianzhan believes that as an important raw material for these industries, steel castings will also have better development opportunities with the development of these industries. At the same time, with the improvement of the technical level of steel castings, there will also be certain development opportunities in aerospace, military and other fields.
With the wide application of steel castings, there are more and more types of steel castings, of which carbon steel and low alloy steel are the most widely used.
Cast carbon steel is a cast steel with carbon as the main alloying element and a small amount of other elements. As the carbon content increases, the strength and hardness of cast carbon steel increase. Cast carbon steel has high strength, plasticity and toughness, and low cost. It is used in heavy machinery to manufacture parts that bear heavy loads, such as steel rolling mill stands and hydraulic press bases. Cast low-alloy steel is a cast steel containing alloying elements such as manganese, chromium, copper, etc., which has greater impact toughness and can obtain better mechanical properties through heat treatment. Casting low-alloy steel has better performance than carbon steel, which can reduce the quality of parts and increase the service life.
With the strengthening of environmental protection law enforcement, steel casting manufacturers are forced to pay attention to environmental protection technology, pay attention to casting smoke and dust treatment, sewage purification, waste sand and waste slag utilization, and develop a variety of casting environmental protection equipment, such as vibration shaker dust hood, mobile Type vacuum cleaners, soot purification devices, sewage purification recycling systems, etc. At the same time, forward-looking entrepreneurs take the initiative to carry out clean production technological transformation and develop “green” casting products, and implement international corporate standards, which is enough to show that improving the quality of castings and promoting green casting is the future development trend of the foundry industry.
Qianzhan Industry Research Institute believes that it is imperative to grasp the technological transformation of the casting industry of steel casting manufacturers, strive to improve the quality of castings, and produce high-performance large-scale machinery and equipment castings. At the same time, we should vigorously publicize and promote energy saving, green casting, and clean production. This is not only necessary for companies to save energy, reduce consumption, improve product quality, reduce pollution, reduce costs, and improve efficiency, but also an important way to break through the green barriers set up by industrialized countries and firmly occupy the international market.
