Coal cutter tooth using should all know.

Carbide Chisel Tungsten Carbide Tips Coal cutter tooth using should all know, it is one of the biggest problems is too vulnerable to damage, wear more serious, so, our manufacturer is the most attention should be to fix the problem of the coal, not only should take preventive measures, but also to encounter problems after the repair work. Coal cutter tooth is the wearing parts used in the process of coal mining, the tooth body wear is one of the main failure forms, to welding repair of wear and tear of the tooth, can improve the service life of the cutter tooth, create objective economic benefits. Prolong the service life of equipment, it will bring us more economic benefits!

Coal winning machine(Carbide Buttons Manufacturers Tungsten Carbide Button Rock Auger Teeth )working environment is very bad, mixed with a large number of impurities such as coal gangue in coal seam, the cutting tooth in high impact and high wear and high stress conditions, the shoulders are big bending moment and shear force, so the coal cutter tooth the tooth body should have a certain hardness, abrasion resistance and toughness. Once we pick by the wear, we should take corresponding measures.

Welding repair of surfacing process was conducted in the abrasion of the tooth body surface after machining, and then to heat treatment to obtain the finished product. 42 crmo steel is a commonly used material, coal cutter tooth the tooth body belongs to the carbon in the conditioning heat resistant steel. Welding process:
1, cleaning before welding, clean coal cutter tooth welding surface impurities such as oil, rust, oil by oxyacetylene flame cleaning, rust with Angle grinder grinding, the surface of fatigue crack with Angle grinder, completely exposed metallic luster.
2, preheating before welding, using oxyacetylene flame swing uniform heating, using infrared thermometer temperature 250 ~ 250 ℃, and keep the interpass temperature about 300 ℃. 850 ℃ quenching heat treatment after welding, use and then go to 500 ~ 600 ℃ tempering treatment, in achieving a certain hardness at the same time to obtain has good wear resistance of bainitic tempered martensite + tempering complex organization. Heat treatment after welding is the main channel of steel to obtain comprehensive performance, material under the condition of its kind, with higher hardness, wear resistance improved significantly.
