What is electroslag steel and what are its benefits?

Electroslag remelting is a smelting process, and the steel processed by this process is called electroslag steel. In the production process of high-speed steel, electroslag steel has significant advantages over electric furnace steel, which is mainly reflected in improving the purity and performance of mold steel. Specifically, the advantages of electroslag steel include:

1. It can effectively reduce the content of harmful elements in steel, with the reduction range reaching 20% to 50%.

2. It can effectively remove non-metallic inclusions in steel, and refine and disperse the residual inclusions, thereby reducing their adverse effects on steel properties.

3. Improve the organizational structure of steel, making it denser and more uniform, avoiding defects such as shrinkage cavities, bubbles, and large particle inclusions, while reducing the segregation of carbides.

4. Improve the impact toughness of steel. Compared with electric furnace steel, the impact toughness of electric slag steel is increased by 20% to 30%.

5. Enhance fatigue strength, improve the anisotropy of steel, make the transverse and longitudinal properties consistent, and the fatigue strength of electroslag steel is increased by 35% compared with electric furnace steel.

6. Tools or molds made of electroslag steel can maintain dimensional stability for a long time, thereby improving processing accuracy.

Although the improvement effect and technical parameters of electroslag steel in different types of mold steel vary, it is indisputable that electroslag steel has made a significant contribution to improving the quality and performance of mold steel, and the improvement effect is intuitively visible.
