一、对十二年来几个重大技术改革的看法十二年来,我国各厂及科研单位在侧碱炉方面进行了许多研究和改进工作,无法一一加以讨论,现仅就摇炉制度、双渣留渣操作、热风碱性化铁炉、转炉热风吹炼、转炉三排风眼、不烘炉炼钢等六方面较重大的问题提出初步看法。(一)摇炉制度:吹炼效果的好坏与风眼和液面的相对位置有密切关系,即与吹炼角度和吹炼深度有关。由于在吹炼过程中铁水不断耗损,使液面不断下降,为了使风眼与铁水面处于一定的合适位置,
First, the views of several major technological reforms in the past 12 years In the past 12 years, various plants and research institutes in our country have carried out many researches and improvements in the side-caustic furnaces and can not discuss them one by one. Slag residue operation, hot air alkaline iron furnace, converter hot air blowing, converter three exhaust eye, not baking furnace steel six major issues raised a preliminary view. (A) Shaker system: The effect of blowing is closely related to the relative positions of the eye and the liquid surface, that is, the angle of blowing and the depth of blowing. As the molten metal in the blowing process constantly depleted, so that the liquid level continues to decline, in order to make the eye of the eye and the molten iron in a certain suitable position,
