PRODUCTION PROCESS

Centrifugal casting of ductile iron pipe production technology

The ductile iron pipes produced by our factory are centrifugally cast by spraying water cooling process. Molten iron at about 1400℃ after melting in the electric furnace is continuously cast into the high-speed rotating tube mold, and the molten iron is solidified to form ductile iron pipes by means of water cooling. The servo motor electric turn-over rack transmission system has better stability than the traditional hydraulic transmission system. More precise. It is beneficial to better control the weight of the tube and the thickness of the tube wall, quality control, and immediately detect the casting defects on the surface of the cast ductile iron pipe to ensure that the quality of the centrifugal cast ductile iron pipe fully meet the requirements.

High temperature annealing of ductile iron pipe production process

After centrifugal casting production of the pipe in the metallogenetic structure there are a large number of cementite and pearlite so that the mechanical properties of the pipe can not meet the requirements of the ISO2531 standard, the need to use the annealing equipment temperature set value of 920℃-950℃ annealing treatment, the basic structure into ferrite as the basic structure of ductile iron pipe, improve the ductile iron pipe toughness, Make its performance meet the requirements of ISO 2531 standard.

The outer surface of ductile iron pipe production process is sprayed with zinc

In order to better make the ductile iron pipe corrosion resistance further enhanced, need to spray metal zinc treatment on the surface of the outer wall of the pipe, the metal zinc spraying material for zinc content of more than 99% metal zinc, zinc layer weight is not less than 130g/㎡, any area zinc layer weight is not less than 110g/㎡, in order to ensure the quality of zinc spray, Zinc spraying should be completed when the tube body itself is still at a certain temperature after the heat treatment process, and no dust and oil should be checked before spraying.
