Tungsten carbide tips cutter picks for underground coal mining

Cut the warm extrusion technology manufacturing tooth body, warm extrusion is in metallic re-crystallization temperature of material forming, molding temperature from 600 to 800 degrees Celsius. In this temperature range, the metal is no longer produce the defects such as oxidation and the grain growth, improve the micro-structure, fine grains, increase the impact toughness of the cutting teeth. At the top of the cobalt cemented carbide carbide and synthesis, formed very high hardness and wear resistance of alloy, the use of advanced welding technology to ensure the high performance ratio of the cutting teeth.

Description

Description of coal mining picks

The tooth body is made of high quality cold extrusion 42CrMo, high density not decarburization. Numerical control lathe processing ensures consistent size. With special heat treatment process of 40-45 degrees, its surface is almost no oxidation, tooth head using isothermal quenching process, its hardness doesn't reduce. Production of cemented carbide by formal domestic companiesYG11C, stable quality can accord customer needs to add welding wear-resisting layer, hardness reaches more than 65 degrees.

Feature of coal cutting picks

1) Replace easily no need special tools;
2) Effective against abrasion working conditions;
3) In the working process don’t produce high temperature spark.

We can also provide mining picks with wear-resistance and laser cladding technique

Application of coal cutting picks

Superior material and technology makes the cutting pick have a impact toughness and high wear resistance. Cutting teeth can’t produce high temperature spark in the working process. Thus is benefit to the safety production of coal mining. Coal cutting teeth often uses with shearer.

Packaging and shipping

Packaging for coal cutter picks is in plastic pail, 10 pieces are in one pail.

Samples are shipped by express, batch products are shipped by sea or by air.

Delivery: 1-5 days for sample, 1-15 days for batch products.
