In the present embodiment, steel plate body 1 is set to manganese steel plate.
In the present embodiment, on steel plate body 1, implement whole parallel built-up welding.
Second embodiment of high abrasion composite panel that is used for chute of the present invention, steel plate body 1 is set to general steel plate, the width d of hardfacing seam 2 is set to 36mm, and the degree of depth h2 of hardfacing seam 2 in steel plate body 1 is set to 6mm, and the height h1 of hardfacing seam 2 is set to 14mm.
The 3rd embodiment of high abrasion composite panel that is used for chute of the present invention, steel plate body 1 is set to manganese steel plate, the width d of hardfacing seam 2 is set to 26mm, and the degree of depth h2 of hardfacing seam 2 in steel plate body 1 is set to 4mm, and the height h1 of hardfacing seam 2 is set to 10mm.
The high abrasion composite panel method for making that is used for chute, use the submerged arc welding machine of electric current as 500-1000A, use abrasion-proof overlaying welding flux-cored wire, have formation hardfacing seam 2 on the steel plate body 1 of high welding performance, hardfacing seam 2 forms the shape of rhombus on the surface of steel plate body 1.
In the embodiment of this method for making, abrasion-proof overlaying welding flux-cored wire is set to HRC greater than 56 open arc self-shield abrasion-proof overlaying welding flux-cored wires.
In the embodiment of this method for making, hardfacing is sewn on the surface of steel plate body and is set to parallel built-up welding.
A kind of chute, the middle plate of chute are set to the high abrasion composite panel that is used for chute in the present embodiment one.
First embodiment of chute after a kind of repair is provided with the high abrasion composite panel that is used for chute in the present embodiment one that width is 70mm in the rear and front end of the middle plate of chute.
Second embodiment of the chute after a kind of repair is provided with the high abrasion composite panel that is used for chute in the present embodiment one that width is 100mm in the rear and front end of the middle plate of chute.
The 3rd embodiment of the chute after a kind of repair is provided with the high abrasion composite panel that is used for chute in the present embodiment one that width is 85mm in the rear and front end of the middle plate of chute.
Existing large-scale slat conveyer chute mostly adopts casting ledge steel, its good welding performance, cost is low, but wear resisting property is poor, plate is welded into the slat conveyer chute in the high abrasion if use, its wear resisting property height, but its welding performance is poor, the cost height, also do not promote the use of widely now, have technology trends at the slat conveyer chute now and be on the steel plate at common high welding performance wearing layer in the melting welding, but the width that has the wearing layer of melting welding on the steel plate of common high welding performance now is to the maximum about 15mm, the built-up welding bed thickness is 2-3mm, does not satisfy the requirement to slat conveyer chute wear resisting property far away.
