一、前言转炉炉龄是影响转炉生产率的重要因素之一,是炼钢厂一项重要的技术经济指标。随着顶底复合吹炼、二次燃烧等转炉冶炼新工艺的出现,炉内冶金反应及工艺操作更加强化,对炉体寿命的要求越来越高。因此,提高转炉炉龄已是国内外冶金科研和技术改进的重要课题。本文将对近年来国内外在转炉炉体冷却技术应用与研究方面所取得进展作一介绍,期望这一新技术能受到我国炼钢工作者的重
I. Preface The furnace age of converter is one of the important factors that affect the converter productivity. It is an important technical and economic index of the steelmaking plant. With the advent of the new process of converter smelting such as top-bottom compound blowing and secondary combustion, the metallurgical reaction in the furnace and the operation of the process are strengthened, and the requirements on the life of the furnace body are getting higher and higher. Therefore, improving the furnace furnace age is an important issue of metallurgical research and technological improvement at home and abroad. This article will introduce the progress made in the application and research of the converter furnace cooling technology at home and abroad in recent years, expecting that the new technology will be able to withstand the weight of the steelmaking workers in our country
