沸腾钢是什么沸腾钢是一种低碳钢。在浇注钢水时,钢水在锭模内凝固的过程中,发生大量的气体(大部份是一氧化碳,小部份是氢和氮),形成一种“沸腾”现象,故称沸腾钢。在沸腾的时候钢锭上部的质点是运动的,所以沸腾钢的上部,在离表面一定距离分布着小的气孔,没有缩孔存在,因此又可称做紧缘钢。这种钢的小气孔,分布良好,控制了钢的脱氧作用,故又称不脱氧钢。沸腾钢的性质与结构由於钢的脱氧程度的不同,制成的钢锭可分为三种:不脱氧钢(紧 Boiling Steel What is Boiling Steel is a type of mild steel. In the pouring of molten steel, molten steel in the ingot mold solidification process, the occurrence of a large amount of gas (mostly carbon monoxide, a small part of hydrogen and nitrogen), forming a “boiling” phenomenon, it is called boiling steel. In the boiling ingot when the upper part of the particle is sports, so the upper part of the boiling steel, a certain distance from the surface of the distribution of small pores, there is no shrinkage, it can be called tight edge steel. The stomatal of this steel, good distribution, control of the deoxidation of steel, it is also known as non-deoxidized steel. Properties and Structure of Boiling Steel Due to the different degree of deoxidation of steel, the steel ingots made can be divided into three types: Non-deoxidized steel (tight
