Origin of domestic explosion-proof tools

As early as 35 years ago, in China's petroleum, chemical, oil refining, oil and gas transportation and other flammable and explosive places, accidents of detonating explosive gases caused by tool friction and impact occurred from time to time, resulting in serious losses of national property and personal safety. There is no guarantee. In order to ensure personal safety and national property from loss, we had to import explosion-proof tools with very expensive foreign exchange (at that time, the price of foreign explosion-proof tools was 4.5 times that of our present). In 1983, at the beginning of reform and opening up, the petrochemical industry rose. Yang Qinglai, senior engineer and chairman of the board, and his R & D team, after careful market research, evaluation, investigation and trial production, decided to develop Chinese explosion-proof tools according to the Japanese JIS explosion-proof tool standard according to the experience of manufacturing mechanical tools of the predecessor. After six years of hard work and thousands of tests, explosion-proof tools that meet the national standards were produced in 1989, filling the national gap. The company was qualified for national import and export in 1996, and the domestic explosion-proof tools went abroad from import to export explosion-proof tools.

In 2018, the general manager of the company was awarded the title of "Chinese good man" for honesty and trustworthiness.

Explosion-proof tool industry development status

Explosion-proof tools have been applied in special fields such as domestic petroleum, chemical, oil refining, oil and gas transportation as early as the 1980 s. However, since the domestic explosion-proof tool industry was not developed at that time, it could only be imported from abroad with foreign exchange, which was not abundant at that time. In order to allow customers to use our own explosion-proof tools, Hebei Zhongbo Explosion-proof Tools Co., Ltd. as the representative of the domestic production enterprises after several years of efforts and continuous practice, and finally manufactured domestic explosion-proof tool products. Over the past 30 years, China's explosion-proof tool manufacturers have always adhered to technological transformation and scientific and technological investment, and silently realized the dream of building China into a world explosion-proof tool manufacturing power through practical actions. According to industry insiders, at present, the explosion-proof tools made in China account for about 80% of the global market space, and the explosion-proof tools made in China occupy a certain position in the international market. According to customs statistics, the products of Hebei Zhongbo Explosion-proof Tools Group Co., Ltd. have reached more than 94.6 percent of the country's export of explosion-proof tools for five consecutive years. The company's domestic market share also reached more than 80%. According to the release of domestic explosion-proof tool manufacturing industry, Hebei and Tianjin are the most concentrated areas of explosion-proof tool industry, especially in Botou City. Botou not only has a large number of explosion-proof tool manufacturers, but also a large-scale explosion-proof tool professional manufacturer-Hebei Zhongbo Explosion-proof Tool Co., Ltd. is located here. At present, China's explosion-proof tool industry has entered the ODM independent design and production stage from the initial OEM OEM production stage. At present, China's explosion-proof tools have advanced manufacturing technology and have entered the fifth-generation product stage to gain a competitive advantage in the international market. ● The first generation of products, learn from the European Danish casting process, cast tire blank processing molding, to the market, to fill the national gap. Cast tire products have pores, trachoma, casting shrinkage, rough surface is not standardized, easy to bend, easy to shape, easy to break, short service life. Note: From 1983 to 1989, domestic materials were manufactured and 23 beryllium bronze smelting and production patents were obtained. ● Second-generation products. The surface of steel mold casting products was refined quickly, which solved the surface blisters and improved the quality of some products, but they were still steel mold casting tire products.

Explosion-proof tool material category

1. Beryllium bronze explosion-proof tools Beryllium bronze is a world-recognized explosion-proof tool manufacturing material. Beryllium is the basic alloy. When beryllium bronze is impacted at high speed or friction at high speed, its mechanical energy is converted into heat energy when it acts on the surface of the object, and the surface temperature suddenly rises. However, due to its high electrical conductivity and thermal conductivity, the heat of the working surface is quickly transferred to other parts of the workpiece, and the heat of the working surface is drastically reduced. Some particles that are detached from the workpiece under impact or friction are not at the temperature of the ignition source. Beryllium bronze intermetallic compounds are relatively stable, and the melting point is high, not easy to violent oxidation. Impact or friction at high speed
