溶解保持炉。 In a melting and holding furnace, a furnace body is rotatably attached to a support stand, and the furnace body is tilted by extension of a piston of a cylinder connecting the support stand and the furnace body to pour molten metal into the furnace. A pulse detection circuit that detects the number of pulses corresponding to the tilting angle, a pulse setting circuit that sets the number of pulses that corresponds to the furnace tilting angle required for the set pouring amount, and the set number of pulses and the detected pulses. A comparison calculation circuit that compares and calculates the number and issues a signal to stop tilting the furnace body when they match, and a tilting stop that calculates the pouring time for pouring metal while stopping the furnace body from the tilting stop angle and the set lubrication amount. A melting and holding furnace comprising: a time calculation circuit; and a return angle calculation circuit that calculates the return angle of the furnace body to a position where the hot water runs out after the tilting stop time has elapsed, and returns the furnace body.
