What are the functions of ductile iron castings

The components of the mechanical equipment we use in our daily lives always suffer from severe wear and tear due to various reasons. If the severely worn components continue to be used, they may result in some serious consequences. Therefore, in order to ensure the service life of the equipment, we usually use Shandong ductile iron castings to replace the severely worn components. Except for the original machine, many parts of the equipment have stopped being replaced. Due to the characteristics of the equipment, some local parts have severe wear, and even if replaced with new parts, the severely worn parts will still show severe wear after a short period of time. For this situation, many friends will choose Shandong ductile iron castings for replacement. The Shandong ductile iron casting manufacturer has informed us that the quality of Shandong ductile iron castings is much higher than the quality of the original parts of the machine. As the reason for the appearance of ductile iron castings is to replace some easily worn parts, their hardness level is high, and in order to cooperate with machine equipment, their appearance still requires lubrication level. In addition, in order to prolong the service life of ductile iron castings in Shandong, manufacturers often adopt a similar process when manufacturing ductile iron castings. By attaching layers on the surface layer of the ductile iron castings, their service life can be extended, and the weather resistance after the attachment layer also increases their service life.

The functional machine tool castings, casting processing, mechanical castings, ductile iron castings, and cast iron platforms cannot be separated from their sorting operations. The use of magnesium or rare earth magnesium as a separation agent for gold spheroidization is added to the molten iron before pouring, resulting in graphite spheroidization, reduced stress concentration, and high strength, elongation, corrosion resistance, and good sealing of the pipe material

1. Surface dust, as castings often stop in dusty areas, there will definitely be dust on the surface. It can be removed by using water or an alkaline solution. If there is adhesive dust, high-pressure water or steam is needed to stop cleaning. If the dust is not clear, it will cause corrosion of the casting over time

2. Surface scratches, rust spots, mechanical methods should be used to stop disposal, polishing, etc., to make the surface of ductile iron castings smooth

3. If the ductile iron casting is broken, the cleaning method is to first clean the adhesive on the rubber ring, bend the rubber ring into a "plum blossom" or "8" shape and install it into the socket groove. Use your hand to press along the entire rubber ring, or use a rubber hammer to compact it. The rubber ring should not be warped or twisted in any part, and should be evenly stuck in the groove. Then, apply the smoothing agent evenly to the inner surface of the rubber ring installed in the socket device When applying a lubricant on the outer surface of the socket, all socket areas outside the socket wire should be evenly brushed. The pipe should be lowered to the bottom of the groove according to the request of the pipe, usually using manual or mechanical lowering methods.

After forming, some substances will remain on the surface of ductile iron castings. Therefore, in order to prevent the occurrence of poor quality during the manufacturing process and ensure the quality of ductile iron castings, cleaning will be stopped after they are formed.
