Why does electric arc furnace steelmaking cost so much electricity?
Updated: 2022-04-28 Attention:
Electric arc furnace steelmaking is a very common steelmaking method at present, but one disadvantage of electric arc furnace steelmaking is that it consumes special electricity. So what is the reason for this? Let's consult the electric arc furnace manufacturer to see how others explain this problem?
Cause analysis of electric arc furnace steelmaking power consumption:
1. Raw materials. As we all know, the steel used for steelmaking is scrap steel, because the raw materials required for steelmaking are light and thin materials, briquettes, etc., which will lead to shutdown due to too high feed temperature during feeding. In this way, the heat loss will be great. If the one-time loading is insufficient, it will need to be fed again, and some even need to be fed three times, which will cause a lot of heat loss. And each feeding needs to increase a lot of power consumption. It is also worth noting that C and P will be higher after the raw materials are purified. When entering the oxidation period, it will take a long time to remove C and P, which will greatly increase the energy consumption.
2. Technology. The technology here refers to the skills of the operator. If the operator's technology is not good, it will waste a lot of lime and energy, which will greatly increase the power consumption.
3. Objective. Objective conditions will also lead to an increase in power consumption. How to understand this? For example, in the process of smelting, we suddenly trip due to the shortage of electric energy. Over time, the molten steel needs to melt again after cooling and solidification. This process will also waste a lot of electric energy.
In addition to the above three points, electric arc furnace steelmaking will cost electricity. Other accidents will also cause electric arc furnace steelmaking to cost electricity. I won't explain them one by one here. Just pay attention to the official website if you want to know! http://www.ttzptc.cn/
