Electro-slag ingot casting device

Abstract

The invention relates to an electro-slag ingot casting device which is characterized by comprising a charging device, a feeding device, a control device, a reaction device and a bottom water tank part, wherein the charging device is arranged above the feeding device; the reaction device is arranged between the control device and the bottom water tank part. Compared with the prior art, the electro-slag ingot casting device has the advantages that (1) the electro-slag ingot casting device is ingenious in overall structural design, compact in structure and high in practicability; (2) steel ingots in different shapes such as a round, a square, a rectangle and a sectional shape with a large wide and narrow surface length ratio can be formed, so that the electro-slag ingot casting device is higher in degree of freedom and wider in application range; (3) the device can further be used for casting castings in different shapes, such as a hollow billet, a high-pressure vessel and a large-sized high-pressure valve; (4) the technical scheme is lower in cost, and convenient to popularize and use in a large scale.

Description

Technical field [0001] The present invention involves a melting casting device, especially a molten casting device, which belongs to the technology field of electric slag heavy melting equipment. Background technique [0002] Electric slag melting casting is a process that makes metal refining and casting into one at one time, producing high -quality alloy castings.It is a technology that uses the resistance heat generated by the current through the current through the current through the fluid residue, and the metal electrodes are constantly melted., Most of the large -scale electric slag melting furnaces in the domestic electric slag metallurgical industry are complicated, the cost is high, and the shape of the steel ingot is limited, and the degree of freedom is small.The high -power transformer that uses single -phase entry in and out of power generally adds a dynamic compensation device to achieve the effect of reducing the impact on the grid. However, the investment is larg...

Problems solved by technology

It uses the resistance heat generated by the current passing through the liquid slag to continuously melt the metal electrode, the molten metal gathers into droplets, passes through the slag layer and drops into the molten metal pool, and solidifies into a casting in a special-shaped water-cooled mold at the same time; Most of the large-scale electroslag remelting furnaces in the domestic electroslag metallurgy industry have complex structures and high costs, and the shape of the formed steel ingot is limited, and the degree of freedom is small; and the output current of the transformer is industrial frequency, the power factor, and the power consumption are large. , high-power transformers that use single-phase power in and out generally need to add dynamic compensation devices to reduce the impact on the power grid, but the investment is relatively large, and a new technical solution is urgently needed to solve the above technical problems
