采用堆焊方法来修复机件,不仅能延长机件寿命,同时往往堆焊层便于选用特殊合金成分,使得机件能获得更优良的性能。本实验的目的是研究用电渣堆焊法修复锤击式破碎机的高锰钢锤头。经一系列实验,使用最廉价易得的材料和极简易的设备,获得了初步结果:用电渣堆焊法,堆焊出相当于高锰钢化学成分的堆焊金属层,经哈尔滨水泥厂在生产中试用证明,基本上能满足要求。
The use of surfacing method to repair parts, not only to extend the life of mechanical parts, while often easy to use surfacing layer of special alloy composition, making the parts can get more excellent performance. The purpose of this experiment is to study the use of electroslag surfacing hammer hammer crusher high manganese steel hammer repair. After a series of experiments, using the cheapest and easy-to-obtain materials and very simple equipment, obtained preliminary results: Electroslag surfacing method, surfacing welding steel equivalent to the chemical composition of high manganese steel surfacing metal layer, the Harbin Cement Plant Proof of production in the trial, basically to meet the requirements.
