Detailed description of the invention
Below for Q255 carbon steel and ZCuSn3Zn11Pb4 tin bronze, specifically describe technical scheme of the present invention.
Q255 carbon steel is usually used in manufacturing the part not too high to requirement of strength, and as the various shaped steel of bolt, key, rocking bar, axle, pull bar and steel construction, steel plate etc., its solid-liquid phase change temperature is at about 1450 DEG C.ZCuSn3Zn11Pb4 tin bronze is a kind of conventional cast copper alloy, and its excellent in mechanical performance, has good Wear vesistance and decay resistance, easily carry out machining, good welding performance, casting constriction coefficient is little, is usually used in making flexible member and wear part.
First, by machining, the Q255 carbon steel bar of corresponding size is processed into the axle sleeve of high 50mm, external diameter 50mm, wall thickness 4mm.Designing and producing corresponding casting mold stand-by, is then the ZCuSn3Zn11Pb4 tin bronze alloys of 5mm at the outer surface casting last layer thickness of above-mentioned Q255 carbon steel axle sleeve with reference to the schematic flow sheet in accompanying drawing 1.Concrete foundry technology process is as follows:
