第一铜矿过去在钎子钢消耗上超过很多,其原因除由于采矿,采准掘进率低、管理上不严密、发生丢失、或用钎子钢作其他工作之外,主要原因是在80～70公分以下的短钎子,只有一部分可以用于‘开眼’,其余都不能使用,因此造成短钎子过多,长钎子不足的情况。本坑车间计划员黄照清同志根据这一情况创造出‘钎子接手’,经过(在水平采矿、采矿的数次试验已获得成功。凡在40公分以上的钎子頭(根据锻钎需要的长度)都能接成长的钎子,並可和普通钎子同样使用。一、钎子接手的制作方法及注意事项(一)原材料为:直径38～40公厘之中空炭素钢,每个长80公厘。
In the past, the first copper mine consumed more than a lot of brazing steel because of the low mining and mining rates, poor management, and the loss or the use of brazing steel for other reasons. The main reason is that at 80 Short braids up to ~ 70 cm can only be used for ’open eyes’ and the rest can not be used, resulting in excessive short brazing and insufficient brazing. According to this situation, Comrade Huang Zhaoqing, a planner of this pit workshop, created a ’brazier takeover’ that has succeeded in several tests of horizontal mining and mining, where the brazing head of more than 40 cm (according to the required length of forging ) Can be connected to the growth of the solder, and the same can be used with ordinary solder .. First, the production method and precautions (1) the raw material is: 38 to 40 mm in diameter hollow carbon steel, each length 80 Mm.
