Collected Papers on Self-Drill Steel and Drill Tools
At present, China's domestic production of several mining cone enterprises are mainly concentrated in Jiangsu, Jiangxi, Liaoning, Henan, Hubei, Sichuan and other regions. On the market, roller cone bits are mainly products with diameters of 250mm and 310mm. At present, due to the downturn in the steel industry and the reduction of surface vein resources for large open-pit iron mines, some open-pit iron mines have begun to compress production or move to underground mining. In addition, in order to reduce production costs, some mines began to choose PDC diamond composite drill bits as drilling tools, so the recent domestic roller bit usage has declined. In order to make up for the decline in domestic market demand, some manufacturers have increased their exports to Australia, South America, Eastern Europe and Mongolia to ensure the balance of the sales market.
At present, only 3-4 enterprises in China's domestic drilling tool production enterprises produce patio drilling tool rolling scraping cutter head, and the annual output value is only tens of millions of yuan. The products are mainly exported to the international market, and the utilization rate in domestic large underground mines is not yet universal. The production of roller cone bits has considerable requirements for equipment (forging, machining, heat treatment) and production technology.
