Casting is one of the basic processes of modern machinery manufacturing industry. As a metal thermal processing technology, casting has gradually matured in my country. Foundry machinery is to use this technology to smelt metal into a liquid that meets certain requirements and pour it into the mold.
The casting production process is many, the lifting and transportation volume is large, the production process is accompanied by high temperature, and various harmful gases, dust, smoke and noise are produced, which makes the casting operation often occur accidents such as burns, fires, explosions and mechanical injuries; it is also easy to Occupational injury such as thermal radiation, poisoning, vibration and silicosis. Therefore, the safety focus of foundry operations is to prevent dust, heat and mechanical injury.
At present, the ratio of the import and export scale of my country’s foundry machinery is 3:1, that is, when my country exports one foundry machine, it imports three foundry machines. The specifications and varieties of my country’s foundry machinery industry are basically complete, but there is a surplus of low-end products and a lack of high-end products.
Judging from the import and export scale of my country’s foundry machinery, this reflects that the demand for mid-to-high-end foundry machinery products in the Chinese market has increased significantly, and it also reflects that domestic mid-to-high-end products are obviously insufficient in terms of technical level and output value, and cannot improve product quality. , technical indicators, user services and other aspects to meet user needs. The level of foundry machinery is directly related to the development level of the foundry industry. The current situation of my country’s foundry machinery industry is difficult to meet the goal of my country’s progress from a large foundry country to a powerful foundry country. The development of China’s foundry machinery industry has a long way to go.
In terms of various casting products, at present, my country’s foundry industry mainly produces automobile iron parts, cast pipes and castings. In 2020, the total output of automobile castings accounted for 28.87% of the national casting output, and the total output of cast pipes and castings accounted for 16.42% of the national casting output, and the two together accounted for more than 45%.
In terms of output, since 2014, the output of automobile castings has remained above 10 million tons, while the output of cast pipes and castings has remained above 6 million tons, and is still showing an upward trend. In 2020, the national output of automobile castings will be 15 million tons, and the output of cast pipes and castings will be 8.53 million tons, both of which have increased compared with the same period of the previous year.
In addition to the stable development of the automobile casting and pipe casting market, my country’s construction machinery casting market has developed rapidly in recent years. Since 2015, the national construction machinery casting production scale has continued to increase. 3.15 million tons in 2015 has increased significantly.
