Meishan tungsten alloy rod manufacturer, CNC blade

Large, medium and small bearings are generally cold installed.Traditionally, the bearing is installed with a hammer head and a section of old pipe.This method can cause the external force to be transmitted through the rolling members, thereby destroying the raceway..The SKF installation special tool releases the external force to the bearing rings that are press-fitted to each other, which is helpful to avoid the damage of the bearing..Before installation, generally use cooking oil bath to heat the bearing.However, this kind of method is likely to pollute the bearing environment and cause the bearing to become invalid too early..In the past, electromagnetic induction heating was a very common trick to heat bearings because of its zoning planning, high efficiency and high heat resistance..

Tungsten is very hard and counts among metals dth hammer It is one of the best, but tungsten carbide, a compound of tungsten and carbon, has higher hardness and is harder than tungsten steel, which is comparable to the extremely hard diamond in nature..The cemented carbide made of tungsten carbide powder has the advantages of high hardness, good wear resistance, high temperature resistance, etc., and can be used for metal cutting tools, drills, drill bits, bulldozer blades, crushing machinery, etc., even small ones used by dentists. The drill bit is also made of cemented carbide.my country's tungsten ore reserves, tungsten ore output, and tungsten trade volume all rank first in the world.

In particular, the bar stock and high-carbide cutting tools, CNC cutting tools have grown strongly, and continue to maintain double-digit growth. The adjustment of the commodity industry structure and the development of industrial chain transformation continue to promote.In my country's tungsten smelters, the production process and product quality have achieved a leading position in the world. The tungsten manufacturing industry has followed the trend of high development in the industrial chain. The production process of cemented carbide tools and the level of weapons and equipment have continued to improve. Product quality and level, and The difference between its competitiveness and excellent overseas companies has become smaller, and it is continuing to develop towards excellent performance, high precision, and high efficiency, and it is approaching the excellent team of global tungsten industry production..

The production capacity of cemented carbide companies has a relatively high market concentration. Zigong Cemented Carbide Mould Co., Ltd. aluminum alloy dth drill pipe Classic numbers are: Stellite1, Stellite4, Stellite6, Stellite8, Stellite12, Stellite20, Stellite31, Stellite100, etc..In China, the key to Zigong Cemented Carbide Mould Co., Ltd. heat-resistant alloy scientific research is more in-depth and in-depth.Unlike other heat-resistant alloys, the heat-resistant alloys of Zigong Cemented Carbide Mould Co., Ltd. are not strengthened by the orderly settling phase that is integrated with the conventional solid.
