本文概述包钢钢轨生产工艺及性能特征。指出通过钢罐吹氩,使用高粘度保护渣浇注,采用低碳保温剂等,减少了表面及内部缺陷;同时在钢锭加热,钢坯清理、钢轨矫直等工序中进行了一系列的技术改进,加上超声波探伤的采用,使钢轨质量得到明显改善。 This article outlines the production technology and performance characteristics of the clad steel rail. It is pointed out that a series of technological improvements have been made in the processes of steel ingot heating, billet cleaning, rail straightening and so on through argon blowing of steel cans, pouring of high-viscosity mold fluxes and using low-carbon thermal insulation agents, Coupled with the use of ultrasonic testing, the rail quality has been significantly improved.
