Abstract

PURPOSE:To hold surface level of molten metal in a pipe at high accuracy without any relation with the molten metal quantity in a holding furnace by detecting reaching of the molten metal supplied by the pipe with a sensor and energizing an electromagnetic pump so that the molten metal in the pipe holds the prescribed molten metal surface by the output signal. CONSTITUTION:When the command signal for pouring the molten metal is made, this signal is lutched with a third lutch IC 76. On the other hand, when the molten metal 12 reaches to the sensor 22 after inputting the command signal for pouring the molten metal, a third multiplexer 74 is changed over from the position shown in the figure with output of the IC 76 and a comparator 62 is moved to return, and digital voltage generated from a programmable voltage generator 56 is impressed to the electromagnetic pump 18 through a D/A converter 60. Then, after completing pouring of molten metal by releasing the command for pouring the molten metal, the third multiplexer 74 is moved to return and the surface level of the molten metal 12 is held to the above range. By the pouring control apparatus in this invention, the accuracy is high and the die casting product having uniform and high quality without containing pin-hole and blow hole can be obtd. under high efficiency.
