The production method of a kind of complex abrasion-proof steel plate of the present invention realizes through following technical scheme: with vacuum electron beam sealing welding common iron material and abrasion-resistant stee material, manufacture the complex abrasion-proof steel plate.
Concrete production stage is following:
(1) compound ordinary steel material and abrasion-resistant stee material be will treat through machined, iron scale, the dirt of treating composite surface removed, and with being processed into same size around the compound material of remain;
(2) the ordinary steel material that processes and abrasion-resistant stee material are stacked together after, on equipment, organize and align together;
(3) will make up adopting vacuum electron beam sealing welding around the material group just in time, form complex abrasion-proof steel plate raw material;
(4) assembly welding is good complex abrasion-proof steel plate raw material is through the heating furnace heating, and 1100-1280 ℃ of heating tapping temperature become a useful person through the milling train thermal processing distortion after coming out of the stove.
Process the raw material of back as rolling wear-resisting steel plate with ordinary steel material and abrasion-resistant stee combination of materials, the ratio of abrasion-resistant stee material and ordinary steel material thickness is 1:5 ~ 1:6.
The ordinary steel material is low-alloy steel material or straight carbon steel.
