Structure Design of P20 Wear-resistant Steel Liner

The structure design of P20 wear-resistant steel plate liner adopts the combination of nest-type and overlay welding wear-resistant steel plate structure, that is, the chute blanking point adopts the hard-surface overlaying wear-resistant steel plate stacking structure, and the tail of the chute and below the blanking point Adopt hard surface welded wear-resistant steel plate as the depressed structure of the depressed plate. The liner at the tail of the chute and under the blanking point also adopts a nest-like structure with 6+14+6 hard-surface wear-resistant steel plates arranged at the resting angle of the material, so that the material directly impacts on the material mat formed by the natural accumulation of loose charge during the distribution. It does not directly impact the chute liner, and the material slides relative to each other when the material slides, reducing the sliding wear of the material on the liner.
 
The chute liner is made of HP308 hardfacing wear-resistant steel plate, and the chute shell is made of SUS304 heat-resistant stainless steel. The bottom plate at the blanking point of the chute adopts a specification of 8+6 (the thickness of the base plate + the thickness of the surfacing layer) hard-faced wear-resistant steel plate, and the rib plate adopts 6+14+6 (that is, the double-sided surfacing 6mm on the 14mm substrate Wear-resistant layer) Hard-face wear-resistant steel plate and surfacing treatment of the ribs are carried out, so that all working surfaces of the chute lining board are wear-resistant layers.
