In the foundry industry, continuous steel casting is a very important production process. Its principle is to continuously cast high-temperature molten steel to finally form a billet with a certain cross-sectional shape and a certain size specification.
We call the equipment used to complete this process "continuous casting equipment".
Today, the editor of Judian will introduce to you: Compared with traditional die casting, what are the advantages of continuous casting.
1. Simplify the production process and shorten the process flow
The continuous casting process eliminates the processes of demoulding, moulding, soaking of steel ingots, and blooming. These saved processes can help users save 40% of their initial investment. Moreover, the structure of continuous casting equipment is simplified, and the floor area is reduced by 30%. At the same time, because the continuous casting equipment is easy to operate, it can effectively help users reduce labor costs.
2. Improved metal yield
In the traditional die casting process, in the production process from molten steel to slab, the loss of cutting head and tail is 10% to 20%. However, the loss of cutting head and tail in continuous casting is only 1% to 2%. The continuous casting process can increase the metal yield by 10% to 14%. If calculated by an increase of 10%, a steel mill with an annual output of 1 million tons of steel can increase the output of 100,000 tons of steel by using the continuous casting process. bring very considerable economic benefits.
3. Reduced energy consumption
The continuous casting process can save the reheating process of the soaking furnace and effectively reduce the energy consumption. Compared with die casting, continuous casting can save energy by 400-1200MJ in the production of LT slabs, which is equivalent to saving 10-30kg of heavy oil fuel. If the continuous casting slab adopts the hot feeding and direct rolling process, the energy consumption can be further reduced, and the processing cycle can be shortened (the time elapsed from the molten steel to the rolled product along the process is: cold charging 30h, hot charging 10h, direct rolling 2h).
4. The production process is mechanized and has a high degree of automation
In the steelmaking production process, the die casting process is labor-intensive and the working environment is relatively harsh. After continuous casting, the equipment operation can be realized by computer control, which greatly improves the labor environment.
This is our introduction to the continuous casting production process today, I hope it can be helpful to you. Welcome to pay attention to our Luoyang Judian, let us provide you with more steel rolling services.
