2013
For changing the current situation that the evanescent mould technology is hardly applied to mining machine casting, the invention provides a casting technique of a coal mining machine casting evanescent mould. The casting technique is characterized by comprising the following steps of selecting materials for preparing a mould sample; preparing the mould sample; preparing a coating; spraying the coating; casing; carrying out vacuum-assist pouring; and cooling. By adoption of the technique, the evanescent mould technology can be applied to the coal mining machine casting; moreover, the process is simple, the finished product is level and smooth, the rejection rate is low, the labor intensity is low, and the casting technique can create great social benefit.
