在炼鋼时,炉渣的化学成分与物理特性变动甚大,每次冶炼均不相同。此种变动直接影响到炉渣与鋼液間的作用,也就影响到鋼貭的优劣,所以电炉炉渣的控制,不仅对炉渣化学成分的調整,也包括炉渣与鋼液的关系。化学分析是控制炉渣的基本方法,但有其缺点,由于它只能示知試样的平均成分,不能区別全部炉渣的組成,而此种組成对于鋼液的影响很大。为了解决此种困难,不时取样是有帮助的。但目前我們化学分析需时較长,即使象在炉渣控制上占极重要地位的氧化鉄或总鉄量能于十五分鐘左右測定完毕,但要測定氧化鈣等需时仍很多,配合不上炉前需要,在试样較多时更感棘手。为此我們拟对氧化鈣等
In the steelmaking, the chemical composition and physical properties of slag vary greatly, each smelting is not the same. Such changes directly affect the role of slag and molten steel, also affect the pros and cons of steel 所, so the furnace slag control, not only to adjust the chemical composition of the slag, but also the relationship between slag and molten steel. Chemical analysis is the basic method of slag control, but has its drawbacks. Since it can only show the average composition of the sample, it can not distinguish the composition of all the slag, which has a great influence on the molten steel. In order to solve such difficulties, it is helpful to take samples from time to time. However, for the time being, chemical analysis takes a long time. Even if the total amount of lutetium oxide or its total amount, which occupies a very important position in slag control, can be measured at about 15 minutes, it still takes a lot of time to measure calcium oxide Need before the furnace, when the sample is more thorny. To this end we intend on calcium oxide and so on
