一概说钎子钢在矿山生产战线上起着主要性的作用,因此其质量良否,不论在技术上或是成本上,都有很大的关系。直接从事于现场工作者对于钎子钢之锻钎作业(obar——plening)已经作了种种的研究和改善,且今后将要永久成为研究的主要问题。在此所谈到的是关于钎子钢之质量鉴定法,根据此种方法,我们必须严格于原钢 Generally speaking, the brazing steel plays a major role in the mine production front. Therefore, the quality of the brazing steel has a great relationship both in terms of technology and cost. Directly engaged in site workers have made various studies and improvements on the obar - plening of the brazing steel, and will continue to be the main issue of the study permanently. What we are talking about here is the quality appraisal method of the brazing steel. According to this method, we must be strict with the original steel
