High Hardness & Wear Resistant Castings For Mining

High hardness alloy materials are widely used superhard wear-resistant materials, due to their high hardness and low fracture properties, It causes frequent cracking in use, shortening the service life of carbide material; also, carbide material The powder particles make it difficult to combine with the steel matrix material, unable to use the conventional welding and casting process To achieve metallurgical fusion with matrix materials, currently generally using copper liquid brazing (bonding) or mechanical combination mode, Due to the low binding strength, easy to fall off and other reasons, the performance of the carbide material is affected.

Melt-casted Cutting Picks for Core Mining/Heading machine

The  tooth head of casted coal cutter picks adopts a coating structure, with high fracture toughness and high wear resistance.

                                                       The mismatch of physical properties at the binding interface between hard alloy                                                         and steel matrix material is determined to alleviate the heat The difference of                                                             expansion coefficient, the effect of high temperature load, the concentration of                                                         interface stress and crack and fracture, its products It can be applied
                                                       in welding and casting production. The core and the cladding layer have                                                                       different hardness, strength, toughness and other mechanics The performance                                                           of the hard metal carbide material made, combined with the interface of the                                                                adhesive phase and the hard phase composition ratio gradually change, its thermal response Force performance and performance also change gradually.

The low price, life is better than the same type of Bravery welding Core cutting picks, cost performance; work department The position tooth material is made of in-situ composite wear-resistant alloy steel, which can be seen in the metallographic photos.

Ladder stare blankly plate used for new-type ball grinding mill
Ladder stare blankly plates used for new-type ball grinding mil are structured with squared concave surface for both sides.The surface of the plates are combined with the magnetic materials on the surface of the ball crusher by inlay.The squared concave frame plates are arranged closelythen it forms scaleboard with ladder-shaped blankly plate.The working face drives ball crusher to move. Because of the effect of concave frame plates structure,it enhances the kinetic of ball-miling. thus it also greatly enhances work efficiency.

High hardness Casted Hammerhead

The product takes a completely different technology from the traditional hammer head production. The wear-resistant part of the front end of the hammer head adopts hard alloy casting process, which melts the wear-resistant hard alloy and matrix material, and the hammer is made of alloy steel with high toughness. The product has a comprehensive performance with strong impact resistance and high wear resistance.

The forged hammer head in the former market are composed of copper brazing process in the hammer surface bonding or mechanical combination process. The alloy block is easy to fall off. Once the alloy block falls off, it is easy to cause partial wear in use, and the hammer head will quickly wear out, not only the hammer head will fail, but also is likely to cause damage to the equipment. Our new hammer adopts the casting process a casting molding, by changing material wettability, enhanced element combination, carbide material and steel matrix material contact surface form diffusion metallurgical fusion transition layer, not only combined with high firmness, good wear resistance, high service life, the technical indicators are more than the traditional hammer, and cost is controllable.
