(一)引言得到最低含量的氧是炼钢生产的最重要任务之一,它在很大程度上决定于脱氧制度是否适当。脱氧的基本目的在于除去液体钢中的氧,不管氧是否熔在钢中或者以氧化物状态存在.氧不仅影响炼钢过程很大,而且影响钢与铁的基本性质:把熔解氧量减少到钢凝固温度时碳与氧平衡数值以下,使钢水结晶时没有一氧化碳放出,因而保证得到结实的钢锭;脱氧剂不仅提高去硫的程度和速度,而且可以减少硫对钢性质的有害影响;氧决定合金元
(I) Introduction Oxygen, which has the lowest oxygen content, is one of the most important tasks in steelmaking and largely depends on the suitability of the deoxygenation system. The basic purpose of deoxidation is to remove oxygen from liquid steel, whether it is molten or in the oxide state of oxygen.Oxygen not only affects the steelmaking process but also affects the basic properties of steel and iron: reducing the amount of dissolved oxygen to Steel solidification temperature carbon and oxygen balance below the value of the molten steel is not carbon monoxide emission, thus ensuring a solid ingot; deoxidizer not only improve the degree and speed of desulfurization, and can reduce the harmful effects of sulfur on steel properties; Oxygen determination Alloy yuan
