METALLIC MOLD PREHEATING APPARATUS AND PREHEATING METHOD, METHOD FOR DESIGNING METALLIC MOLD PREHEATING APPARATUS

摘要

PROBLEM TO BE SOLVED: To improve product yield by performing the optimization of temperature distribution on the surface of a metallic mold in a short time and fully excluding a testing shot process, when the metallic mold for casting is preheated.;SOLUTION: Systems for a plurality of burners 7, 8, 9 are classified at each necessary temperature zone. Further, the adjustment of supplying amounts of gas and air to respective systems 12, 13 of the supplying means of the gas and the air to the respective burners 7, 8, 9 is performed with a control means 14. The necessary calorie is given in each prescribed portion of the metallic mold for casting, and the temperature distribution on the surface of the metallic mold for securing the good casting quality can be realized in a short time.;COPYRIGHT: (C)2005,JPO&NCIPI
