時(shí)間:2020-06-13   訪問量:1746

There will be a layer of paint on the surface of the centrifugal casting, this is to make the workpiece in the best condition. And few people know about the operation process of coatings for centrifugal castings? The following is the basic content related to it.


When casting a workpiece, you need to bake the mold first, remove the water vapor and increase the mold temperature to prevent explosion and splashing. Baking can be done with blowtorch or red iron block, etc., and it is also ready for drying the paint.


The next step is to clean the mold, push the asbestos pad, close and lock the front cover, put the spout and so on. Use the paint tube to pour the paint into the mold, which can be poured after the paint is dried into a shell, but it should be noted that the paint tube is easy to collide with the rotating front end cover and cause an accident. Therefore, when the paint tube is drawn out, Start the machine to rotate by driving to ensure safety.


After the casting is completed, in order to obtain the refined grain structure, water spray cooling can be appropriate, but it is necessary to pay attention to the control of temperature and time to avoid affecting the thickness of the paint.
