Shearer picks

The shearer cutter produced by Henan Coal Science and Technology Wear-Resistant Technology Co., Ltd. adopts 42CrMo material for one-time cold forging forming process, and the tooth body has high mechanical strength. The alloy head adopts a coarse-grained tungsten-cobalt alloy head, which can greatly improve the service life of the shearer cutter.

采煤机截齿 Shear picks

Shearer pick is a very important component of coal mining comprehensive mining equipment, and its performance directly affects mining efficiency. After analyzing the cutting mechanism of the picks and the combined forces of compression, shear and impact under light, medium and heavy conditions of cutting coal seams, coal-rock mixed layers and rock layers, and analysis of the reasons for the failure of the picks, Henan Academy of Coal Science Abrasion Technology Co., Ltd. has produced "non-spark wear-resistant picks", which has the following characteristics:

One: The pick tooth body is preferably made of high-strength alloy structural steel. It adopts a single cold forging process. The internal structure is uniform and the grains are fine.
Second: The outer surface of the upper cone of the pick is reinforced by micro-arc plasma cladding technology, which improves the overall wear resistance of the pick and can effectively prevent the alloy head from falling off.
3: The alloy head uses coarse-grained tungsten-cobalt cemented carbide, which has the characteristics of uniform hardness, impact resistance, and wear resistance, and is suitable for harsh working conditions under the mine.
Four: The pick-cutting solder is made of copper-based solder and flux imported from the United States. The welding strength is increased by 30%, which effectively guarantees the welding strength of the cemented carbide head and the tooth body.
Five: When the pick cone is brazed with a hard alloy head, the outer surface of the alloy head and the inner surface of the matching hole are micro-porous, which increases the area of brazing filler metal during brazing and strengthens Wetness between solder, tooth head and tooth body.
Six: Ceramic particles are added to the cladding material, and no spark will be generated when the cladding layer collides with the rock.
Seven: Micro-arc plasma cladding technology of wear-resistant hardened picks, the cladding layer and the substrate are deeply combined, uniform hardness, wear resistance, impact resistance, thereby greatly improving its service life.
Eight: Aigang series of coal picks have obtained 2 national invention patents and 3 utility model patents.

研究与应用 Research and Application

The shearers produced by our company are actually used by large-scale mines such as Shanxi Coking Coal, Shanxi Lu'an Group, Zhengmei Group, Yushuwan Coal Mine (10 million tons of mines, and Eickel units in Germany), and their service life is similar to that of similar products. 2 ~ 3 times, won the recognition and praise of application customers.
