由于柱齿钎头与片状钎头相比具有其独特的一些优点,因而,近年来,柱齿钎头在国外被迅速推广使用,予计将有取代片状钎头的趋势。在我国由于机械化程度不高,矿山风压较低(4～5公斤/厘米~2),全面推广和取代片状钎头尚不可能,但较大面积的推广却正在进行中,其经济效果也是显著的。如葛洲坝工程使用柱齿小钎头11000只,节约资金100万元。云柱锡公司松树脚矿签订了推广使用中型柱齿钎头的奖惩合同,矿方在一个采场一年使用钎头共276只,节约资金21000元。随着矿山机械化程度的提高及管理水平的改进,使用柱齿钎头的经济效果,将越来越明显,柱齿钎头将会有越来越广阔的前景。目前,全国一些钎头生产厂也陆续开始生产柱齿钎头,有些矿山也开始自己制造柱齿钎头,如龙烟铁矿、大厂、漓渚铁矿等。制造柱齿钎头的关键工艺——固齿,在国内均有不同程度的报道,有的认为焊接固齿是
Because of the unique advantages of columnar shaving heads compared with flaky sharpening heads, in recent years, the sharpening of shank teeth has rapidly been promoted abroad. It is expected that there will be a tendency to replace flaking shaving heads. In our country, due to the low degree of mechanization and the lower mine pressure (4 ~ 5 kg / cm ~ 2), it is impossible to promote and replace the flaky brazing heads in an all-round way. However, the promotion of larger area is underway and its economic effect It is also significant. For example, Gezhouba Project uses 11,000 small tooth heads to save 1 million yuan. Yunzhu tin company foot pine mine signed a promotion of the use of medium-sized column teeth drill bit reward and punishment contracts, mining side in a stope a total of 276 bits of drill bit, saving 21,000 yuan. With the improvement of mine mechanization and improvement of management level, the economic effect of using columnar bit will be more and more obvious. There will be more and more broad prospects for columnar bit. At present, some drill bit production plants across the country have gradually begun to produce column tooth drill bits. Some mines have also started to manufacture column tooth bits by themselves, such as Longyan Iron Mine, Dachang, and Lizhu Iron Mine. The key process of making the teeth of the column teeth - solid teeth, are reported in varying degrees in China, and some think that welding solid teeth is
