Over-flow type maguesium alloy melt quantitative transfering apparatus

Abstract

The invention relates to an overflow type magnesium alloy fused mass fix quantity transferring device that sets quantifying room in crucible, which forms overflow system with material transferring pipeline. The invention decreases the contact area with air in the transferring process, and the protecting gas is supplied through simple pore and would not easy to make melt oxidize or material jamming and decrease gas supplying and thermal losing. The transferring efficiency would be improved.

Description

technical field

[0001] The invention relates to an overflow device for quantitatively transferring magnesium alloy melt from melting equipment to other equipment, and belongs to the technical field of material processing equipment. Background technique

[0002] In the field of magnesium alloy forming, it is usually necessary to transfer the high-temperature magnesium alloy melt from its melting and holding equipment to other equipment such as die-casting machines and rolling mills. During the transfer process of the melt, not only requires constant temperature, stable flow, no oxidation, but also requires accurate quantification, efficient transfer process and simple equipment maintenance.

[0003] The current quantitative transfer devices for magnesium alloy melt are mainly divided into pneumatic type and pump type. Pneumatic transfer device fills the surface of the magnesium alloy melt in the closed crucible with a certain pressure of inert gas, and uses the gas pressure ...

Examples

Embodiment Construction

[0012] The specific structure and working process of the present invention will be further described below in conjunction with the accompanying drawings.

[0013] The overflow type magnesium alloy melt quantitative transfer device provided by the present invention comprises a crucible 1, a quantitative pump 8 and a feeding pipe 22, and a melting chamber 2, a heat preservation chamber 3 and a quantitative chamber 4 are arranged in the crucible; the melting chamber and the heat preservation chamber Heating and heat preservation are carried out independently; a high liquid level probe 5 and a low liquid level probe 6 are installed in the melting chamber, and the liquid level of the melting chamber and the heat preservation chamber is controlled between the high and low liquid level probes, so the liquid level can be ignored The influence of small changes of the quantitative pump on the amount of melt transferred by the quantitative pump; the melting chamber and the heat preservati...
