Abstract

The utility model discloses a sliding water gap brick used for a molten steel ladle, which is characterized in that an upper sliding board brick and a lower sliding board brick are two parallel plates. Two surfaces of the sliding board bricks are both sliding planes. The two surfaces of the upper sliding board brick and a lower sliding board brick of the utility model can be used. The service life is effectively prolonged with economic performance.

Description

A kind of steel ladle sliding sprue tile for smelting

The utility model relates to a kind of sliding sprue tile for smelting that is used for liquid metal casting ladle gate valve, specifically the refractory material sliding sprue tile for smelting in the molten steel casting ladle slide gate nozzle gate valve is improved.

Sliding sprue tile for smelting of the prior art such as Fig. 1; this class sliding sprue tile for smelting is made up of upper nozzle brick 1, upper slide brick 2, lower skateboard brick 3 and lower nozzle brick 4; between upper nozzle brick 1 and the upper slide brick 2; between lower skateboard brick 3 and the lower nozzle brick tongue and

groove interface

5,6 clampings that rely on convex-concave; so upper and lower sliding plate brick slip working face only is the A face; the back surface B face is unrenewable; owing to around upper and lower sliding plate brick, all be with the ferrule protection, therefore only use the one side of upper and lower sliding plate brick to seem uneconomical.

The purpose of this utility model is to provide a kind of improved sliding sprue tile for smelting, and it can make the two sides of upper and lower sliding plate brick all can use.

The technical solution of the utility model is achieved in that a kind of steel ladle sliding sprue tile for smelting, it is made up of upper nozzle brick, upper slide brick, lower skateboard brick, lower nozzle brick successively, in upper and lower sliding plate brick, the upper and lower nozzle brick tap hole is arranged all, it is characterized in that: upper and lower sliding plate brick is two blocks of parallel-plates, and their two faces are slip plane.

The utility model is owing to be improved to two blocks of parallel-plates with upper and lower sliding plate brick, and their two faces are slip plane, so the two sides all can be used, have prolonged the service life of upper and lower slip brick effectively, have more economy.

Fig. 1 is a sliding sprue tile for smelting cutaway view of the prior art

Fig. 2 is a cutaway view of the present utility model

Fig. 3-Figure 10 is the vertical view of the upper and lower sliding plate brick embodiment among Fig. 2

The utility model will be further described below in conjunction with drawings and Examples

The utility model is by upper nozzle brick 1, upper slide brick 2, lower skateboard brick 3, lower nozzle brick 4 is formed, on, the lower skateboard brick, on, one tap hole 7 is all arranged in the lower nozzle brick, it is different from prior art: upper slide brick 2, lower skateboard brick 3 is two blocks of parallel-plates, their two faces, be face A, face B is slip plane, these two faces can form through attrition process, in an embodiment with last, the lower skateboard brick match on, lower nozzle brick also is the plane, with original tenon interface 5, the clamping of blind mortise interface 6, change the plane into and connect, on, lower nozzle brick 1,4 with last,

lower skateboard brick

2,3 contact-making surface also can form through attrition process; Shape such as Fig. 3 to Figure 10 of upper and lower sliding plate brick among the embodiment, the shape of general upper and lower sliding plate brick can be circle, avette, oval, double trapezoid, rectangle, circle and adds rectangle, ellipse and add trapezoidal, circle and add trapezoidal, rectangle and add trapezoidal, or other well-regulated shape, fillet all can be made in all obtuse angles in them.

Claims

1. steel ladle sliding sprue tile for smelting, it is made up of upper nozzle brick, upper slide brick, lower skateboard brick, lower nozzle brick successively, in upper and lower sliding plate brick, the upper and lower nozzle brick tap hole is arranged all, it is characterized in that: upper and lower sliding plate brick is two blocks of parallel-plates, and their two faces are slip plane.
