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 at the same time solidifies into a casting in a special-shaped water-cooled mold; The bottom water tank is one of the most critical structural components in the melting and casting device. The bottom water tank closes the space formed by the crystallizer from below, and the bottom where the steel ingot starts to melt. The shape of the bottom water tank is generally adapted to the shape of the melted ingot, but the existing The bottom water tanks generally have the following problems: 1) The structure is complex, 2) The contact between the bottom plate and the mold is poor, which affects the casting effect, 3) It is easy to be electrically broken down during the production process; 4) The cost is high. Once a problem occurs, the entire The structure needs to be completely replaced, therefore, a new technical solution is urgently needed to solve the above technical problems

Embodiment 1

[0013] Example 1 : see figure 1 , a bottom water tank for a special-shaped melting and casting device, the bottom water tank includes a support 1, a working plate 2 arranged on the support 1, cooling fixtures 3 are provided on both sides of the working plate 3, and a cooling fixture 3 is provided on one side of the support 1. The water pipe 5 is provided with an outlet pipe 6 above the water inlet pipe, and a crystallizer 7 is provided above the working plate. In order to introduce and discharge cooling water, a water inlet pipe is arranged on one side of the bracket, and a water outlet pipe is arranged above the water inlet pipe. The water inlet pipe and the water outlet pipe are welded on the bracket or fixed on the bracket by a gasket. The overall structure is ingeniously designed, compact, and low in cost, and the bottom water tank can ensure good contact between the bottom plate and the mold, avoid electrical breakdown, and ensure good casting results.

Embodiment 2

[0014] Example 2 : see figure 1 , as an improvement of the present invention, the bottom water tank further includes a gasket, and the gasket is arranged on the bracket 1 . The rest of the structures and advantages are exactly the same as in Embodiment 1.

Embodiment 3

[0015] Example 3 : see figure 1 , as an improvement of the present invention, the shape of the working plate 2 is one of flat, concave and convex. In this technical solution, the working plate 2 bears the heat load and electric load of the bottom plate, and the shape of the working plate is set as one of flat, concave, and convex, so as to form the required shape of the lower part of the electroslag ingot. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Abstract

The invention relates to a bottom water tank for an irregular casting device. The bottom water tank is characterized by comprising a bracket and a working plate, wherein the working plate is arranged on the bracket; cooling clamps are arranged on two sides of the working plate; a water inlet tube is arranged on one side of the bracket; a water outlet tube is arranged on the water inlet tube; a crystallizer is arranged above the working plate. Compared with the prior art, the bottom water tank has the advantages that firstly, the bottom water tank is smart in overall structural design, compact in structure and high in practicability; secondly, good contact of the cooling clamps and the crystallizer can be ensured, electric breakdown can be avoided, and a good casting effect can be ensured; thirdly, the technical scheme is relatively low in cost and convenient in large-scale popularization and application.

Description

technical field [0001] The invention relates to a melting and casting structural part, in particular to a bottom water tank for a special-shaped melting and casting device, and belongs to the technical field of electroslag remelting equipment. Background technique [0002] Electroslag casting is an electroslag metallurgy process that completes metal refining and casting at one time to produce high-quality alloy castings. 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 at the same time solidifies into a casting in a special-shaped water-cooled mold; The bottom water tank is one of the most critical structural components in the melting and casting device. The bottom water tank closes the space formed by the crystallizer from below, and the bottom where the steel ingot starts to melt. The s...
