Embodiment Construction

[0012] As shown in the accompanying drawings, the submerged metal liquid valve of the present invention contains a melting furnace 2 and a holding furnace 8, and the corresponding positions at the bottom of the furnace wall of the melting furnace 2 and the holding furnace 8 are respectively processed with an outlet 13 and an inlet 10. A delivery pipe 9 is indirectly arranged so that the inner cavity of the melting furnace 2 and the holding furnace 8 is communicated. Wherein the delivery pipe 9 is a silicon carbide pipe. A circulating cooling medium source 12 is arranged between the melting furnace 2 and the holding furnace 8, and the circulating cooling medium source may be circulating cooling water, circulating compressed air or other refrigerants. The refrigerant is a refrigerant for refrigerators or air conditioners. Condenser 3 is arranged on delivery pipe 9, and this condenser can be made by coiling with metal conduit, also can be metal water jacket etc. Both ends of th...

Abstract

The undercurrent type molten metal valve includes smelting furnace and heat retaining furnace, and features that the smelting furnace and the heat retaining furnace are communicated through conveying pipe to connect the bottoms of the furnaces. On the conveying pipe, there is a condensator communicated with one circulating cooling medium source and separated into two sections separately on two ends of the conveying pipe. On the middle part of the conveying pipe, there is inducing coil wound with conducting metal pipe, connected to controllable power source and with inner cavity connected also to the cooling medium source. Using the undercurrent type molten metal valve to convey molten metal can prevent air suction and slag inclusion to raise casting quality. The present invention is suitable for in casting industry.

Description

(1) Technical field [0001] The invention relates to a liquid metal valve. Specifically, it is a submerged molten metal valve that uses heating or cooling to open or close the molten metal flowing through the pipeline. It is suitable for opening or closing the pipeline for conveying molten metal between the melting furnace and the holding furnace in the foundry industry. (2) Background technology [0002] In the foundry industry, the molten metal melted by the melting furnace and adjusted in chemical composition needs to be sent to the holding furnace for heat preservation before it can be drawn out through the casting machine and cast. At present, the common method of sending the molten metal in the melting furnace into the holding furnace is the differential launder method. In the level difference laundering method, the melting furnace and the holding furnace are arranged one high and one low respectively, so that a drop is formed between the melting furnace and the holdin...
