Coal mining pick is one of the vulnerable parts in coal mining and roadway tunneling machinery, and it is the main tool for falling coal and crushing coal. Its working environment is very bad, and its performance directly affects the production capacity of coal mining machinery., Power consumption, work stability and the service life of other related parts. It must have high wear resistance, very high strength and toughness.
The new standard for the coal industry-the pick material is defined as alloy structural steel. The general coal pick material in domestic plants is 35, which is a high-strength steel. To meet the above heat treatment requirements, the heat treatment process must be isothermal quenching. Arguably, under such strict requirements, the performance of the pick is as follows:
1. There are many kinds of picks and different shapes, which can adapt to various working conditions. The working environment that the shearer "encounters" is different. For example, if the hardness of some coal rocks is low, the engineers will use picks with the same hardness, and vice versa, they will need to use the same type of high hardness picks.
At present, the common shapes of shearer pick are flat and pick. Among them, the flat pick is suitable for cutting coal with different hardness, such as hard type and viscous type. The pick pick is more suitable for brittle coal. This extends the useful life of the different picks.
2. The pick and the equipment for fixing the pick itself are simple. In order to improve the efficiency of the project, the picks produced now are very user-friendly. Engineers can not only quickly install and fix them, but also easily disassemble and maintain them after use.
3, good wear resistance, more production process ---, really realize the beauty---. It is understood that the materials used to make cutting teeth are more in line with the environmental needs of engineering personnel. Not only is it good in wear resistance, coal mining cutting teeth are cheap, and it is also more secure. Moreover, in terms of price, the new pick has not become expensive because.
