Core-coated wire technology is a means of refining outside the furnace with the progress of science and technology. Alloy core-coated wire is used in steelmaking, which can purify the form of steel inclusions, improve the castability of molten steel, and significantly improve the yield of ferroalloy, reduce alloy consumption, reduce steelmaking costs, and have significant economic benefits.
The technical specifications of the cored wire are as follows:
1. feed line calcium treatment of liquid steel, liquid steel reaction is stable, avoid secondary oxidation, inclusions float fast, clean liquid steel effect is good.
2. it is conducive to the fine-tuning control of the composition of steel.
3. the yield of alloy increased significantly.
4. the feeding line can avoid the gas into the liquid steel.
5. feed line adaptability, wide range of applications.
6. the feeding line is operated by the equipment, easy maintenance, production safety, no pollution to the environment.
Through the core-coated wire production process, it can be seen that core-coated wire is a means of auxiliary smelting steel, and the performance of molten steel can be significantly improved by this means of off-furnace refining, which is very conducive to the reduction of steelmaking costs of enterprises.
