Talking about the performance of the processing superiority of the mandrel continuous casting roll
Through the introduction to everyone in the editor, I believe that many friends have mastered and understood the requirements of various processing technologies and processes in our industrial production and processing, but these are not enough, because with the needs of our product production, Now we have a lot of more advanced production technology, especially the mandrel continuous casting roll processing, because the advanced technology makes the mandrel continuous casting roll processing more energy-saving and green, let’s learn about the lower mandrel continuous casting roll processing. Superiority.
Because the mandrel continuous casting roll can omit the blooming process, it not only saves the energy consumption of the soaking furnace, but also shortens the cycle time from molten steel to slab. In recent years, one of the main developments of mandrel continuous casting rolls is the trend of casting slabs close to the cross-sectional dimensions of the finished product, which will further simplify the steel rolling process. The yield from molten steel to billet using ingot mold casting is about 84-88%, while continuous casting is about 95-96%. Therefore, the use of continuous casting process can save metal by 7-12%, which is a considerable figure. .
One of the important reasons why the Japanese steel industry is competitive in the world is the large-scale adoption of continuous casting in the steel industry. For the expensive special steel, stainless steel, the continuous casting method is used for casting, and its economic value is greater. According to relevant information, the production of 1 ton of continuous casting billet saves energy by 627～1046KJ compared with die casting billet, which is equivalent to 21.4～35.7kg standard coal, and the energy consumption saved by increasing the yield rate is more than 100kg standard coal. According to China’s current energy consumption level, the comprehensive energy saving per ton of continuous casting billet is about 130kg standard coal.
It seems that we still need to adopt this advanced processing technology. Although the total amount of resources in our country is relatively large, the per capita occupation is very small, and the exploitation of these resources is very strong, so we carry out continuous casting of mandrels. When roll processing, we still try to choose more advanced energy-saving processing technology, which not only saves our resources, but also plays a role in protecting the environment. This is the demand of our industrial development and the development of our era.
