With the development and progress of the times, cast iron bushing has also occupied a place in the foundry industry. No matter what equipment and original parts are cleaned, it is very important, because it will affect the effect when you use it next time. Therefore, some materials will remain on the surface of ductile castings after molding. Therefore, in order to avoid bad scenes during the production process and to achieve better quality of ductile castings, they will be cleaned after molding. The following is about the cleaning of cast iron bushing.

1. Dust on the surface, because castings are often carried out in dusty occasions, there must be dust on the surface. It can be removed with water or alkaline solution. If there is adhesive dirt, high-pressure water or steam is needed to clean it. If the dust is not clear, it will cause corrosion of the casting over time.

2. Surface scratches and rust spots are treated mechanically, polished, polished, etc., to restore a good surface to the nodular graphite castings.

3. If the iron casting is broken, the cleaning method: first wipe the adhesive on the rubber ring first, bend the rubber ring into a "plum blossom" or "8" shape into the socket groove, and use your hand to run the entire rubber ring Press it again, or smash it with a rubber hammer to ensure that all parts of the rubber ring are not warped and twisted evenly, and are evenly stuck in the groove. Apply the lubricant evenly to the inner surface of the rubber ring installed in the socket and the outer surface of the socket When applying lubricant, brush all the socket parts except the socket line. The pipe should be lowered to the bottom of the tank according to the requirements of the pipe, usually by manual pipe down method or mechanical pipe down method.

A cast iron bushing with good quality and complete performance is inseparable from its cleaning work. Magnesium or rare earth magnesium combined with gold spheroidizing agent is added to the molten iron before pouring to spheroidize the graphite and reduce the stress concentration, so that the pipe has high strength, high elongation, impact resistance, corrosion resistance, and good sealing.
