1. Carbide buttons

  Carbide buttons have unique properties and are widely used in mining, water wells, oil field drilling and coal mining equipment. Depending on the oilfield drilling machinery, such as cone drill bits, down-the-hole drill bits, geotechnical drilling tools, etc. Carbide buttons are used in shearer drill tools, mining machine tools and road maintenance tools for snow clearing and road milling. Carbide mining down-the-hole drills are widely used in rock tools, mining tools for quarrying and mining, tunneling and civil construction. The ball teeth are pressed into the hole of the drill through an interference fit and cannot be removed once in, ensuring the effectiveness of the drill.

2. Material

  Tungsten carbide (WC) is an inorganic compound containing equal parts of tungsten and carbon atoms. Colloquially, tungsten carbide is often simply called carbide. In its most basic form, it is a fine gray powder, but it can be pressed into shape and used in industrial machinery, tools, and abrasives. In 1923, Schroeter of Germany added 10% to 20% cobalt as a binder to tungsten carbide powder and invented a new alloy of tungsten carbide and cobalt. Its hardness is second only to diamond. This is the world's artificial The first cemented carbide. Cemented carbide is a powder metallurgical product made of carbide (WC, TiC) micron powder of high-hardness refractory metal as the main component, with cobalt (Co) as the binder, and sintered in a vacuum furnace or hydrogen reduction furnace. . Mining tools: rocks with high hardness and large impact load use coarse-grained WC. Rocks with small impact and low impact load use medium-grained WC as raw materials.
