论文部分内容阅读
本文是根据上海钢研所杨宁、张庆安、宋宝瑞同志所写的“高炉料钟埋弧自动堆焊”、上海重机厂金结构车间李本华同志所写的“高炉大料钟、大料斗的耐磨合金高效率自动堆焊”与上钢八厂李志芳同志写的“用陶质焊剂制造新型耐磨合金在高炉料钟堆焊中的应用”综合而成的。对于应用陶质焊剂达到掺合金目的制造新型复合层耐磨金属,是五十年代在我国问世的,但一直未得到推广应用。然而,近几年来,上海钢研所、四川中国电焊条厂、梅山工程指挥部、冶金部建筑研究院及上海重机厂等对这项新工艺进行了联合试验,并首次应用于冶金工业的高炉料钟,料斗的堆焊,取得了可喜的成绩。本文就这三篇文章中的合金设计、渣系选择、堆焊工艺等作一综合报道,供学习参考。
This article is based on the Shanghai Steel Research Institute Yang Ning, Zhang Qingan, Comrade Song Baorui written by the “blast furnace clock submerged arc automatic surfacing,” Shanghai Heavy Machinery Factory gold structure workshop comrades written by Li Benhua, “blast furnace large bell, hopper resistance Grinding alloy high-efficiency automatic welding ”and the steel plant eight Comrades Comrade Li Zhifang written“ with ceramic welding flux new wear-resistant alloy in the blast furnace bell surfacing applications ”integrated. For the application of ceramic flux to achieve the purpose of blending gold to create a new composite wear-resistant metal layer is the fifties came out in our country, but has not been popularized. However, in recent years, Shanghai Steel Research Institute, Sichuan China Welding Electrode Factory, Meishan Engineering Headquarters, Metallurgical Construction Research Institute and Shanghai Heavy Machinery Factory conducted a joint test of this new technology and applied to the metallurgical industry for the first time Blast furnace clock, hopper surfacing, made gratifying achievements. In this paper, the three articles in the alloy design, slag system selection, surfacing technology made a comprehensive report for reference.
