Coal Mining Teeth U95-25- Jixing

Coal Mining Teeth U95-25

Product Description

In soft coal seams, the pick can cut quickly, improving efficiency and reducing resistance; in medium and hard coal seams, its optimized cutter shape design effectively improves cutting force and reduces equipment wear; in hard coal seams, high-strength alloy cutter heads can withstand Strong impact ensures long-term stable operation.

Product advantages

It is welded with a low-alloy structural steel tool body and a cemented carbide tool head. The hardness of the tool body (40~45HRC) and impact toughness (≥49J/c-m²) are improved through a heat treatment process. In addition to coal mining, it has expanded to fields such as metal mining and tunnel engineering (such as shield machine picks).

Classification application

By shape: knife type (low cutting resistance), pick type (suitable for hard rock). By material: ordinary type, wear-resistant type, sandstone special type (with alloy strips).

Scope of application

In practical applications, suitable rotary digging teeth need to be selected according to the geological characteristics of the construction site to ensure construction efficiency and safety.

Product performance

Wear resistance: Cemented carbide tips can still maintain high hardness at high temperatures of 600~800 ° C, but insufficient red hardness may lead to softening and accelerated wear. Impact resistance: Special geometric tooth head designs (such as tapered, curved) reduce cutting resistance and reduce the risk of broken shank.
