我矿由于沒有鍛钎設备,风鑽打眼用的十字形钎子起初全靠金嶺鉄矿协助鍛制,由于往返搬运費用很大,供应不及时,影响正常生产。因此,在党的領导和积极支持下,經过多次試驗,土法鍛钎終于成功,现簡要介紹如下: (一) 钎头的锻制:其作业次序和操作方法如下: 1.钎鋼加热:加热时間2～3分鐘。加热部分长度为15公分。加热至鋼头呈紅色即可(溫度約1000°)。 2.端部鈍粗:在鑄鉄座或鉄砧子上进行。鈍至头部胀大近似等于钎头直径即可。鈍时应尽量使钎 Due to the lack of forging and brazing equipment, our mine used cross-shaped brazing tools for drilling and drilling of wind drills to assist in forging due to Jinling Antimony Mine. Due to the heavy transportation expenses, the supply was not timely and affected normal production. Therefore, under the leadership of the party and with active support, after several trials, the method of earth forging and brazing was finally successful. Now it is briefly introduced as follows: (1) Forging of bit heads: The operation sequence and operation method are as follows: 1. Brazing Steel heating: heating time 2 to 3 minutes. The heating section is 15 cm in length. Heating until the steel head is red (temperature about 1000°). 2. Dullness of the end: It is carried out on a castor or anvil. Bluntness to head swelling is approximately equal to the tip diameter. When blunt, try to make the brazing
