Cr18Ni12Mo2Ti钢属于奥氏体不锈耐酸钢,这种钢的特点是:①含铬量高。这么高的铬,要是放在还原期加入,那末即使把铬合金烤得很热,仍会使钢液大量降温,并因吸收大量的熔化热而使钢液进一步降温。这样,还原期就会拖得很长。再者,还原期加入大量铁合金,将给钢液带入大量的气体。所以,冶炼这一类的高铬钢,希望大部分的铬合金能在熔化期装入。但是这种装料法,不采用特殊工艺,那末铬的损失将是很可
Cr18Ni12Mo2Ti steel is austenitic stainless steel, the characteristics of this steel are: ① high chromium content. Such a high level of chromium, if added during the reduction period, will leave even a very hot chrome alloy, which will still cause a significant cooling of the molten steel and a further cooling of the molten steel due to the absorption of a large amount of heat of fusion. In this way, the reduction period will be dragged very long. Furthermore, adding a large amount of ferroalloy during the reduction period will bring a large amount of gas into the molten steel. Therefore, smelting this type of high chromium steel, hope most of the chromium alloy can be loaded in the melting period. However, this charge method, without using a special process, then the loss of chromium will be very acceptable
