前言沸腾钢由于钢水沸腾反应的洗涤作用,在钢锭表皮层形成干净的沸腾层,钢锭表面美观,而且与镇静钢相比,钢坯收得率高、生产成本低,所以被大量作为低强度薄板生产用钢。
Preface Boiling steels form a clean boiling layer in the ingot skin due to the washing effect of the boiling reaction of molten steel. The surface of the ingot is beautiful. Compared with the killed steel, the yield of the billet is high and the production cost is low. Therefore, it is widely used as a low- Steel.
