During normal crushing operation, the hardened layer at the tip of the drill rod of the crushing hammer is hard to the core, and the overall hardness of the head is relatively high, and the edges and corners are distinct, so it has better wear resistance and correspondingly brittle. Therefore, the new broken hammer drill rod just used should pay attention to the correct method of operation: although in the beginning of use, it is not appropriate to use too much impact force, nor to operate directly on rocks with high hardness.
Just like the warm-up before human movement, the new drill rod is preheated for a period of time in the place where the hardness is relatively low and the force is lower at the initial operation. After preheating, the toughness and plasticity of the tip of the drill rod can be improved, so that the drill rod can be in a better working state.
In addition, in the crushing of reinforced concrete structures, the tip of the drill rod will be broken by forced pulling after it is stuck in the steel bar. Customers are requested to re-machine and sharpen the drill rod before continuing to use it.
Correct treatment after tip prizing: The drill rod tip should be stopped immediately after it is found to be broken. If the drill rod tip continues to be used after it is broken, there will be a phenomenon of block dropping. Customers are requested to re-machine and sharpen the drill rod before continuing to use it.
Gujian drill rod belongs to Jiangyin Jiangnan Heat Treatment Co., Ltd. It can produce various types of hydraulic crushing hammer drill rod by using its own professional heat treatment advantages and complete advanced equipment, and set stricter enterprise standards on the basis of national standards. It can also produce different types and qualities of drill rods according to the materials produced by different technological processes of different steel mills to meet the diversified needs of customers, and break the passive situation that domestic high-end drill rods rely entirely on imports, thus filling the gap in China. And with high performance price ratio, product quality meets the real needs of customers.
