Tungsten carbide coal picks are vulnerable parts of mining machinery.
Coal picks are mainly used for coal mining and roadway, tunnel, ground trenching and other projects. It is mainly equipped with coal mining machines, roadheaders, milling machines and other equipment. Through long-term analysis and research on coal picks, the company has analyzed the reliability of coal picks from several aspects such as selection of new coal picks, arrangement of coal picks and improvement of pick structure. Improve the reliability of coal picks, reduce the proportion of coal pick consumption in the cost per ton of coal, and increase the effective working time of coal shearers.2. The type of coal pick is mainly divided according to the hardness of the coal to be mined, the type of coal pick seat and other factors. The picks are divided into: U62, U47, U82, U84, U85, U92, U94, U95, S100, S120, S135, S150, S160, S170 and other models, if there are special models, can be produced in quantitative quantities.
Mainly features:
• high durability due to wear-resistant tempered steel
• high grade tungsten carbide tip
• excellent rotation (and thus uniform wear) and secure seating due to a clamping sleeve
• high degree of solder quality
• extraction groove for easy tooth replacement
Carbide columnar coal pick
Tungsten carbide columnar coal pick is a high-quality hard alloy pick dedicated to coal shearers. It is made by pressing and sintering a series of metallurgical powder processes such as mixing tungsten carbide and cobalt powder, ball milling, etc. It has high strength and its characteristics For the characteristics of good wear resistance and long service life. It is widely used in various coal shearers and roadheaders for roadways, tunnels, ground trenching and other projects.
Advantages of carbide columnar coal picks:
1. Corrosion resistance, no rust, long service life, 1 to 2.5 times that of traditional coal picks.
2. The brazing is firm, no desoldering phenomenon, high working efficiency: 3.5 times that of the old coal pick.
3. Good energy-saving efficiency: because the number of replacements is greatly reduced, the downtime of the shearer is shortened, and the mining cost is reduced.
4. Wide range of application: Our company has developed high-strength tungsten steel hard rock coal picks for different coal seams according to different hardness coal seams, which are basically divided into ordinary wear-resistant seam coal picks for F1-F3 layers; F4-F6 Sandstone coal picks for grade sandstone layers; high-strength hard rock coal picks for F7-F9 grades.
Flake coal pick
Advantages of carbide flaky coal picks:
1. Long service life, 1-1.5 times that of traditional coal picks.
2. High working efficiency: 2.5 times that of the old-fashioned coal picks.
3. Good energy-saving efficiency: because the number of replacements is greatly reduced, the downtime of the shearer is shortened, and the mining cost is reduced. Yield quality standard: A. Cone hardness: HRC>65B, Pick shaft hardness: HRC28°-32° Surface hardness: HV>2000 Adopt special heat treatment process, reach 40-45 degrees, and the surface is basically free of oxidation.
4. Our company According to the hardness of the coal seam, high-strength hard rock coal picks for different coal seams have been developed, which are basically divided into ordinary wear-resistant seam coal picks for F1-F3 layers; sandstone coal picks for F4-F6 sandstone layers; F7 -F9 grade high-strength hard rock coal picks, according to the theory of using different coal picks for different coal seams, greatly reduces the production cost of customers, improves work efficiency and saves expenses.
Tungsten carbide special-shaped coal picks
Tungsten carbide special-shaped coal picks are mainly used to make shield teeth for drilling into hard rock formations and hard rock formations, coal shearers, fully mechanized mining machines, fully mechanized excavators, continuous miners, roadheaders, rotary excavators, Coal picks, rotary digging teeth, picks.
The process is powder making→formulation according to the application requirements→wet grinding→mixing→crushing→drying→sieving→adding forming agent→re-drying→sieving to obtain a mixture→granulation→cold isostatic pressing→forming → SHIP sintering → forming (tungsten steel approved material rough) → packaging → storage.
Cemented carbide road pick
The tooth body of the cemented carbide road pick is made of heat-treated high-strength alloy steel, which can maintain high strength, toughness and high wear resistance; the pick springs are all made of high-strength spring steel, and the pick springs have excellent wear resistance. The head of the coal pick adopts austempering process, so the hardness does not decrease. The cemented carbide adopts YG13C produced by regular domestic manufacturers, and the quality is stable. The wear-resistant layer can be welded according to customer needs. Pick hardness reaches 65 degrees or more.
Advantages of road picks:
1. Long service life, 1-1.5 times that of traditional coal picks.
2. High working efficiency: 2.5 times that of the old-fashioned coal picks.
3. Good energy-saving efficiency: the number of replacements of the picks is greatly reduced, the picks shorten the downtime of the shearer, and the picks reduce the mining cost.
Fourth, our company's pick output quality standards:
A. Cone hardness: HRC>65;
B. Rod hardness: HRC28°-32°;
C. Surface hardness: HV>2000; the pick adopts a special heat treatment process, the pick reaches 40-45 degrees, and the pick surface is basically free of oxidation.
After years of practical experience, the patented product non-sparking hard rock coal picks for gas coal mines has been developed. Improve production efficiency and ensure the personal safety of miners.
