Introduction of open health steel
Open hearth steel refers to carbon steel and ordinary low-alloy steel that are smelted by open hearth. According to the properties of the lining material, it is divided into acid hearth steel and alkaline hearth steel. Process for treating molten steel with argon in an open-hearth molten pool. Trials were carried out in open hearth furnaces with capacities of 150, 300 and 430t. Steel is smelted using the scrap-ore method according to the current process. The metal blowing Ar was carried out by a tilted oxygen gun on the furnace top, and the gas consumption was 400 to 1200 m / (h · gun). The YKOC-1 sensor was used to check the oxygen activity in the melt before and after spraying. In the smelting group, metal and slag samples are selected from the furnace.
