Improved ceramic core firing method
The invention discloses an improved ceramic core firing method. The technical problems of long time, high possibility of bulging, cracking and trace formation and the like of the conventional ceramic core in a wax removal stage are mainly solved. According to the method, n-heptane is used for dissolving and removing a part of a plasticizer in a ceramic core green body, and an open passage facilitating discharging of the plasticizer is formed on the premise of ensuring sufficient green body strength; in a later firing process, the plasticizer can be easily discharged from the formed open passage, so that the aims of shortening firing time and reducing the defects of a wax removal process are fulfilled; the firing cycle can be remarkably shortened, the firing time can be shortened to be within 10 hours, the firing qualified rate of the product can be increased, and the method has an important promotion effect on energy resource saving, cost reduction and expansion of the application range of the ceramic core.
