Recently, the development of China's welding tool industry has shown a trend of pick-up. The development of the mining accessories industry in China has been in a stagnant state for a while, and the development of the coal mining industry has been slow. On the 1st, there were many coal mines inviting tenders all over the country. Our gorgeous sales department phone kept ringing, and some dealers were inviting tenders for mines to make inquiries about our products. It seems that winter is the peak period for the development of our industry. Since the beginning of winter, the development of the domestic drill industry has surpassed the development of foreign countries.

2. A large amount of 95CrMo and T8Cr are used, but the process has not been fully grasped and understood. There are early fractures and failures in the use of the drill rods-brazed shoulder breaks, blowouts, breaks, etc., and the overall level is worse than 55SiMnMo. .
3. The power of the rock drill is increased. For example, the 7565 rock drill is 65J, YT28 rock drill, 76J, and YJ29 rock drill is 82J . In order to promote the three small rock drills and blasting, H22 drill rods are still used to make the drill rods in the rock drilling process Increased load .
From this point of view, in the future development, the development of domestic tools will become better and better!
