The full name of electroslag steel is electroslag remelted steel. As the name suggests, it is a steel ingot that needs to be melted twice. This process is more complicated than electric furnace steel. The performance of the opposite steel is much better, including the purity of steel and other electroslag steel.

Electroslag steel is more expensive than electric furnace steel because electroslag steel is called electroslag remelted steel. As the name suggests, it is a steel ingot that needs to be melted twice. This process is more complicated than electric furnace steel, and the performance of the opposite steel is much better, including The purity of the steel is equal to the following. The non-metallic inclusions in the steel are absorbed by the slag. Harmful elements (sulfur, lead, antimony, antimony, tin) in steel are effectively removed by steel-slag reaction and high-temperature gasification. The liquid metal is substantially covered by the slag pool and substantially avoids reoxidation. Because it is melted, refined, and solidified in a copper water-cooled crystallizer, this eliminates the contamination of steel by refractory materials. Before the steel ingot is solidified, there is a metal molten pool and a slag pool at its upper end, which serves as heat preservation and feeding to ensure the compactness of the steel ingot. The rising slag pool forms a thin slag shell on the inner wall of the crystallizer, which not only makes the surface of the steel ingot smooth, but also acts as insulation and heat insulation, so that more heat is transmitted to the lower part, which is beneficial to the directional crystallization of the steel ingot from bottom to top. Due to the above reasons, the quality and performance of the ingot produced by electroslag remelting are improved, and the plasticity and impact toughness of the alloy steel at low temperature, room temperature and high temperature are enhanced, and the service life of the steel is prolonged.
