Heat-resistant steel castings are heat-resistant steel used as raw material, through a certain process of casting a workpiece, is unique compared to other casting performance. While we have a lot of casting process to understand, but how about the heat-resistant steel castings molding is still relatively unfamiliar, followed by the non-Xifuaier Metal Technology Co., Ltd. to tell it.

To get a good quality heat-resistant steel castings, the first step is pre-foamed, is through steam rapid heating mode it will be used for the production of raw material beads models advance to the appropriate density; even then stabilized after processing before it can be fed into the mold steel, the raw materials after heated state will change, eventually sticky integrally formed model.
This is just the initial stage, the model should be stored before using it for some time aging stability, then the block model Adhesive binding and dipping process, the purpose is to make the internal bore of all cluster models of dry sand and peripherals have been tight and real support. After the completion of the metal can be poured into it, after the model material vaporized and replaced by a metal at high temperatures to form a casting we need. After casting, the casting will be solidified and cooled in the sand box, and then only need to clean off the sand and the entire process is complete.
