Title: Production of casting
Inventor: MAGUSA SHIYUNKAI
IPC: B22D35/04
Filed: 1979-09-13
Abstract: PURPOSE: To obtain a sound casting with a good casting yield by installing a float composed of a refractory material of specific gravity smaller than that of the molten metal to be poured and having a hollow part in the longitudinal direction into the mold space and pouring the molten metal through the hollow part of this float.  
     CONSTITUTION: A float 5 comprising a refractory material of specific gravity smaller than that of pouring metal and having mechanical strength and heat resistance  and having a hollow part 6 is installed in the mold. Thence, when pouring of molten metal is performed through the hollow part 6 of the float 5, the molten metal  poured passes through the gaps or resembling places and spreads in the mold sapce  9. As the molten metal level ascends, the float 5 also ascends. With this constitution, the molten metal of high temperature is successively replenished always to the  surface layer part of the molten metal level in the mold; therefore, the ideal temperature gradient is formed from the bottom of the mold inside toward upward.

Then when the hard copy (printing) key is depressed by the keyboard of the screen display terminal side, the state of the printer hardware is confirmed and it is judged that the drawing processing is under way. For this judgement, the synchronous type function is sent to a drawing data group transmission queue that a server holds and a response is expected to received.  After the response is received, a hard copy printing process is started on condition that the return value indicates normal response reception, and the printing processing is carried out to perform output to a hard copy printer.
