Application:
1) Thermal power plant: lining plate of medium speed pulverizer barrel, impeller shell of fan, inlet flue of dust remover, ash duct, lining plate of bucket wheel, connecting pipe of separator, lining plate of coal crusher, lining plate of coal hopper and crusher, burner burner nozzle, lining plate of coal hopper and funnel, air preheater support, guide vane of separator. The above parts have no high requirements for the hardness and wear resistance of the wear-resistant steel plate. The wear-resistant steel plate with the material of NM360 / 400 and the thickness of 6-10 mm can be used.
2) Coal Yard: feed chute and hopper lining, hopper lining, fan blade, pusher bottom plate, cyclone dust collector, coke guide lining, ball mill lining, bit stabilizer, screw feeder bell and base, Kneader bucket lining, ring feeder, tipper bottom plate. The working environment of the coal yard is very bad, so it has certain requirements for the corrosion resistance and wear resistance strength of the wear-resistant steel plate. It is recommended to use the nm400 / 450 wear-resistant steel plate with a thickness of 8-26mm.
