本专利是从高炉出铁沟中取铁水样,用电位法快速测定其硅含量,再按此含量调整脱硅条件的有关脱硅的控制方法。高炉铁水含有大量的碳,转炉吹炼是将这些碳氧化去除,同时升温至铸锭所需要的温度。以往,在这个过程中总是将脱碳与脱硅、脱磷、脱硫等一道进行,造成大量的钢渣,使吹炼条件不易控制,终点碳与钢水温度产生波动,甚至脱硫、脱磷亦不稳定,以致生产的钢材不十分纯净。为此,最近已将脱磷和脱硫与转炉吹炼分开进行,使后者作
This patent is taken from the blast furnace taphole to take a sample of molten iron, with the potential method of rapid determination of silicon content, and then adjust the content of desiliconization conditions related to desiliconization control method. Blast furnace hot metal contains a lot of carbon, converter blowing is to remove these carbon oxides, while heating to the required ingot temperature. In the past, decarburization and desilication, dephosphorization and desulphurization were always carried out in this process, resulting in a large amount of steel slag, which makes the blowing conditions difficult to control, the temperature of the end point carbon and molten steel fluctuate, and even the desulfurization and dephosphorization are not Stable, so that the production of steel is not very pure. For this reason, dephosphorization and desulfurization have been recently conducted separately from the converter blowing, making the latter work
