问:磁分析方法是否可用于转炉炼钢终点碳的控制检验? (张炤) 答:(1)磁分析方法一般可用于平炉炼钢炉前定钢液碳量。由于碳素钢含碳量与钢的磁导率有一定关系,这种仪表也称为导磁测碳计。应用时,将钢液注入仪表中的一根铅笔状的模中。俟钢液凝结后,即可由表上读出碳量。仪表中当然包含磁化电路与二级线圈等。每测定一次一般需要三分钟左右。(2)转炉炼钢终点控制有采用光电池的。现有一种简单直接观察用的小型光谱
Q: Can magnetic analysis be used for the control test of carbon at the end of BOF? (Zhang) Answer: (1) The magnetic analysis method can generally be used to determine the amount of carbon steel in front of open hearth steelmaking furnace. Due to the carbon content of carbon steel and the permeability of steel has a certain relationship, this instrument is also known as the magnetometer. In use, the molten steel is injected into a pencil-like mold in the instrument.俟 molten steel condensation, you can read out the amount of carbon from the table. Of course, the instrument contains magnetizing circuits and secondary coils. Each measurement generally takes about three minutes. (2) the end of the converter steel control using photovoltaic cells. There is a simple direct observation of the small spectrum
