Lime: lime in steelmaking applications. It is mixed with molten steel, having a rapid slagging (slag) removal rate and improve the S (sulfur) removal of P (phosphorus) efficiency. Active lime used in the process of steelmaking also has: Asher Whitehead shorten the refining time, improve the furnace, lower raw material consumption buy lime powder, increase production, quality, reduce costs, operating stability lime powder, help smelting advantages of automation. Lime: lime quality requirements. The so-called active, refers to the ability to respond lime and water. Activity on behalf of the ability of lime in the molten steel with other substances (impurities) reactions. Because lime powder production line, to directly measure the lime in the slag during the reaction speed of the molten steel is very difficult. At the same time, it can be used to determine the quality of calcined lime and guidance through the level of detection of the activity of production. Thus, it created a demand for calcined lime products for the activity of the testing requirements.
