At present, the main smelting furnaces are vacuum induction smelting furnace, electric arc smelting furnace and electroslag remelting.

Common smelting methods and heating principles

Chinese steel output is increasing day by day, and the growth rate is very fast. However, the proportion of electric furnace steel is not large.

In the circulating cooling water system, due to the inlet water quality and other reasons, it often leads to scale and corrosion. At the same time, there will be a large number of bacteria breeding, thus forming dirt. This paper will introduce the common control methods of scale and dirt in circulating cooling water.

The lining of medium frequency furnace depends on the size of the furnace to decide whether to use castable or ramming material.
