在本刊第八期上见到王坚同志的文章后，个人对钎库损坏问题有些意见，提出来和大家研究一下：钎库损坏的原因，总的说是两方面，一是钎库本身的质量不好，一是操作有问题。钎库的损坏主要表现在库断、库裂和库老。按照王坚同志的意见，损坏的原因主要是钎杆锥体制造问题，这是不够妥当的，应该说除了钎库本身质量问题外主要是操作方面的问题，也就是安钎头和卸钎头的问题，为什么呢？
After I saw Comrade Wang Jian’s essay in my eighth issue, I personally had some opinions on the issue of brazing library damage. I came up with a study on the causes of the damage to the brazing library. Generally speaking, there are two aspects. One is the braze library itself The quality is not good, first, there is a problem with the operation. Brazing library damage is mainly manifested in the library off, library cracking and library old. According to Comrade Wang Jian’s opinion, the main reason for the damage is the manufacture of drill rod cones. This is not proper enough. In addition to the quality problems of the braze reservoir itself, it is mainly an operational problem, that is, The question, why?
