PRODUCTION PROCESS
Preparation of hot meta
Blast furnace ironmaking: The quality of hot metal is closely related to the composition of raw materials. Our company tests each batch of raw materials, refines low-phosphorus and low-sulfur hot metal, and ensures that the content of carbon, phosphorus and sulfur in the hot metal meets the requirements.
Centrifugal casting
Centrifugal casting: Our company uses the water metal process for centrifugal casting. The molten iron at about 1360C after melting in the electric furnace is continuously poured into the high-speed rotating pipe mold, and the molten iron is solidified by water cooling to form a ductile iron pipe. Quality control: The cast ductile iron pipe is immediately inspected for casting defects on the surface to ensure the quality of the centrifugally cast ductile iron pipe.
Finishing
Weighing: Use electronic scale to weigh each ductile iron pipe to ensure that the weight of the pipe meets the quality standard requirements. Zinc spraying: In order to further enhance the corrosion resistance of ductile iron centrifugal cast iron pipes, zinc spraying is required on the outer surface of the pipe. Metal zinc spraying is used, and the material is metal zinc with a zinc content of more than 99%. The weight of the zinc layer is not less than 130g/m’, and the weight of the zinc layer in any area is not less than 110g/m’. To ensure the quality of zinc spraying, zinc spraying should be carried out after the heat treatment process is completed and the pipe body itself is still at a certain temperature.
