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.
The high abrasion composite panel that is used for chute of the utility model and second embodiment of chute; 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 utility model and chute; 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.
Use the submerged arc welding machine of electric current as 500-1000A; Use abrasion-proof overlaying welding flux-cored wire; Has the wear-resisting weld seam of formation on the steel plate body of high welding performance; Hardfacing is sewn on the shape that forms on the surface of plate in the chute and is set to rhombus, and hardfacing is sewn on the surface of steel plate body and is set to parallel built-up welding, in chute, forms diamond tread design on the plate; Abrasion-proof overlaying welding flux-cored wire is set to open arc self-shield abrasion-proof overlaying welding flux-cored wire, and 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.
A kind of chute, the middle plate of chute are set to the high abrasion composite panel and the chute that are 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 and the chute that are 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 and the chute that are used for chute in the present embodiment one that width is 100mm in the rear and front end of the middle plate of chute.
