Container capable of transporting molten metal received therein to separate factory and method of producing the container

Abstract

A container capable of transferring molten metal from a factory that produces a molten metals such as molten aluminum alloys and so on to a factory that uses the molten metal while the molten metal being stored therein and supplying the molten metal to a use point using the pressure difference. The container comprises a frame 1a and a lining 2 having a passage for flowing the molten metal therein. The passage 34 is being provided at an inside of the frame and at least a part thereof is being surrounded by a member restricting a flow of a gas. The pipe 34 is, for example, made of a metal and inside thereof has a lining layer 34b formed with a refractory member. The pipe 34 may be structured with a ceramics. As such structure being adopted, even when a crack and the like is formed in the lining 2 of the container, the flow of a gas is shut off, resulting in stable supply of the molten metal.

Description

technical field [0001] The present invention relates to containers for transporting and supplying, for example, molten aluminum alloys to points of use. Background technique [0002] In a factory that performs aluminum molding using a plurality of die casting machines, not only the aluminum material inside the factory but also the aluminum material outside the factory are often supplied. At this time, the container containing the aluminum in the molten state is transported from the factory on the material supply side to the factory on the molding side, and the material in the molten state is supplied to each die casting machine (for example, document 1: Japanese Patent Application Publication No. 3-31063 (Fig. 1)). [0003] The inventors of the present invention have proposed a technique of supplying materials from such a container to a molding machine using a pressure difference. That is, in this technique, the inside of the container is pressurized, and the molten metal ...

AI Technical Summary

Problems solved by technology

[0005] However, the lining in the container has a problem that cracks are generated due to thermal expansion, mechanical impact, etc., and when the crack reaches the flow path from the space of the container, the pressurized gas passes through the crack and directly flows into the flow path. , resulting in unstable supply

However, this kind of container must be heated (or preheated) before use, and a large thermal load is applied to the casting tube during heating, so there are durability problems such as immediate rupture of the casting tube.
