Automatic magnesium alloy quantifying furnace

Abstract

The invention relates to the technical field of quantifying furnaces, in particular to an automatic magnesium alloy quantifying furnace. The automatic magnesium alloy quantifying furnace comprises guide rails, wherein a furnace frame is arranged on the guide rails; a furnace body is arranged on the furnace frame; a material pump and a crucible are arranged in the furnace body; a floating ball detection system is arranged above the furnace body; an inlet of the crucible is connected with an automatic magnesium ingot feeding device; a liquid outlet of the crucible is provided with a counter flange; the counter flange is connected with a liquid conveying pipe; the automatic magnesium ingot feeding device, the floating ball detection system and the material pump are connected with a PLC (Programmable Logic Controller); the floating ball detection system is capable of accurately detecting the liquid level height of magnesium liquid in the furnace body, and then conveying a detection result to the PLC; the PLC thus controls the feeding timing and the feeding speed of the automatic magnesium ingot feeding device; the PLC controls the rotating speed of a rotating shaft of the material pump according to the liquid level height of the magnesium liquid and the size of a die pressed casting so as to control the liquid conveying amount, and the precise quantification conveyance of the magnesium liquid is realized. The size error of the conveyed magnesium liquid does not exceed 0.5%, the precision is high, and the sealing effect is good.

Description

technical field [0001] The invention relates to the technical field of dosing furnaces, in particular to an automatic dosing furnace for magnesium alloys. Background technique [0002] At present, the quantitative furnace for magnesium alloy mainly includes the following structures: heating furnace, crucible, discharge pipe, control system and lifting platform, etc. Magnesium ingots are added into the sealed crucible through the feeding port, and enter the heat preservation room after being melted in the melting chamber , and then through the discharge pipe, enter the die-casting machine for die-casting, complete the die-casting cycle, the existing magnesium alloy automatic quantitative furnace quantitative is not accurate enough, the control of the quantitative delivery of the magnesium alloy liquid is difficult to grasp, can not achieve accurate control, resulting in large errors The quality of the product is affected; in addition, the discharge port of the automatic quant...
