[0022] Example 1:
[0023] Double-liquid centrifugal casting manufacturing method of bimetal composite wear-resistant pipe, see for process flow Figure 4 , See the structure diagram of the composite wear-resistant pipe during the manufacturing process figure 1 , Follow the steps below in sequence:
[0024] a) Coating preparation. The water-based graphite coating is prepared according to the volume ratio of water to graphite powder of 1:0.3~1.0, the particle size of graphite powder is generally 10~100um;
[0025] b) Spraying on the inner surface of the mold tube. Spray the prepared water-based graphite paint uniformly on the inner surface of the centrifuge mold tube 1, so that the bimetal composite wear-resistant tube can be pulled out of the centrifuge mold tube 1, and its thickness is 0.05-0.15mm;
[0026] c) Dry paint and mold tube encapsulation. Use flame to dry the paint on the inner surface of the mold tube; encapsulate both ends of the centrifuge mold tube 1, and the encaps...

[0030] Example 2:
[0031] Manufacture the bimetal composite wear-resistant straight pipe with an inner diameter of Φ133mm, a length of 6m, and an inner lining thickness of 5mm. Process flow see Figure 4 , See the structure diagram of the composite wear-resistant pipe during the manufacturing process figure 1 , Follow the steps below:
[0032] a) Coating preparation. The water-based graphite coating is prepared according to the volume ratio of water to graphite powder of 1:0.5;
[0033] b) Spraying on the inner surface of the mold tube. Spray the prepared water-based graphite paint uniformly on the inner surface of the centrifuge mold tube 1, the thickness of which is about 0.1mm;
[0034] c) Dry paint and mold tube encapsulation. Use flame to dry the paint on the inner surface of the mold tube 1; and encapsulate the two ends of the centrifuge mold tube 1;
[0035] d) Manufacture of outer sleeve. Molten steel, melt A3 steel melt in an intermediate frequency furnace, and measure 0...
