Embodiment Construction
[0008] In conjunction with the accompanying drawings, the new manufacturing process of the bimetallic composite liner of the present invention includes molding and pouring, and the process steps are as follows: (1) use a special mold to shape, place the thin steel plate C welded with the steel brace D in the cavity, and the thin steel plate C divides the cavity into two separate parts, that is, the wear-resistant layer A and the ordinary steel layer B; several steel braces are welded on the thin steel plate to enhance the composite strength, and the thin steel plate can also be adjusted according to the thickness of the wear-resistant layer its shape and angle. (2) Use a self-made automatic pouring machine to pour molten steel, control the temperature of molten steel in wear-resistant layer A at 1350°C, and control the temperature of molten steel in ordinary steel layer B at 1510°C-1550°C. When pouring, pour wear-resistant layer A first, and wait for the molten steel When the ...
