The classification of rock drilling tools (drilling tools) in the steel drilling tool industry
160 years ago, the Swedish Nobel and his sons, following the Chinese gunpowder, invented nitroglycerin colloidal explosives and used them in road construction and mining, which triggered the "real industrial revolution" that led to the rapid growth of social wealth. Until 1921, Schluttel, Germany, invented WC-Co cemented carbide, which quickly formed two major industries: cemented carbide cutting tools and cemented carbide rock drilling tools (drilling tools), which led to the rapid development of machinery and mining industries and was known as "industry" Developing teeth". The two great inventions of industrial explosives and cemented carbide have greatly increased the ability of mankind to conquer nature, accelerated the development of transportation, energy, and resources, and promoted the rapid development of basic industries such as metallurgy, machinery, electronics, chemicals, and construction. Promoted the rise of high-tech industries such as nuclear energy, computers, and aerospace.
So far, modern rock drilling and blasting technology and geotechnical excavation operations have become the main means for mankind to obtain resources from rocks and open up space for survival and development underground. This requires long-term cooperation between experts in rock drilling, blasting, rock crushing, mining, materials, metallurgy, steel, machinery, physics, chemical engineering, electronics, mathematics, mechanics, and biology (simulation). The development of long-life rock drilling tools (drilling tools) has become a major engineering technical problem that must be solved in the new century for the global mining industry to deal with rocks with high efficiency and low consumption.
The mining industry is one of the basic industries of the national economy. In order to improve the living conditions and environment, human beings need to extract more resources, expand a wider living space, build more convenient roads, and build more energy and defense bases. Rock drilling tools (drilling tools) are indispensable tools in mining and infrastructure construction. They are used in domestic and foreign mining, railway, highway construction, ports, power station defense projects, etc., as well as urban construction, quarrying and other fields. Various types of rock drilling tools (drilling tools) products are used. Rock drilling tools (drilling tools) are tools for drilling blast holes in rock or rock soil drilling and blasting construction, depending on the construction method and operation method. , It can be divided into several categories, such as top hammer type, scraping type, down-the-hole type, rotary type, etc., with thousands of specifications.
