熔摸铸钢常选用工频感应炉(酸性炉衬)熔炼,它的化学成分中的硅是很难控制的一种元素。在熔炼过程中,硅有时不但没减少,反应增加,甚至超出给定的工艺范围,见表1、表2。为此,下面谈谈使用工频感应炉(酸性炉衬)炼钢时硅超差的主要原因,熔模铸钢化学成分中硅的合理含量,进而提出在生产中如何控制硅的含量。一、硅起差的主要原因 1.熔炼设备:使用工频炉(酸性炉衬)熔炼铸钢时,在氧化期,金属中的硅与空气中的氧和铁锈中 Melting cast steel often use frequency induction furnace (acid lining) smelting, its chemical composition of silicon is a very difficult to control an element. In the smelting process, sometimes not only did not reduce the silicon, the reaction increased, or even beyond the scope of a given process, see Table 1, Table 2. To this end, the following talk about the use of frequency induction furnace (acid lining), the main reason for silicon ultra-poor steelmaking, chemical composition of the investment casting of silicon in the reasonable content, and then put forward in the production of how to control the silicon content. First, the main reason for the difference between silicon 1. Melting equipment: the use of frequency furnace (acid lining) smelting cast steel, the oxidation period, the metal in the silicon and air oxygen and rust
