Abstract

This invention relates to the steel industry. The purpose of the invention is to increase the durability of the runners by reducing the load on their outer zones. The shutter consists of fixed and movable refractory plates and a collector glass. The plates are pressed together using the support plate 6 through balancers 7 and rollers 8 enclosed in separators 9. Rollers 8 are offset from each other by 0.2-0.5 of their length, and the support surface of the runners 10 and 11 is inclined relative to the horizontal by 1 - 3 °. 1 hp f-ly, 2 ill., 2 tab.

Description

FIG. g

The invention relates to ferrous metallurgy and can be used for casting metal from steel-ladle ladles.

The aim of the invention is to increase the durability of the runners by reducing the load on their outer zones.

Figure 1 shows the valve steel - (casting bucket, the cutj in ia figure 2 - node I in figure 1.

R

The shutter includes a fixed plate 1, a movable plate 2, a glass collector 3. The stationary plate 1 is enclosed in a steel ferrule 4, the movable plate 2 and a collector glass 3 are enclosed in a movable ferrule 5. The plates are clamped to one another. Kim's plate 6 through balancers 7 and rollers 8 enclosed in separators 9. The supporting surface for the rollers is formed by the runners 10 and 11, made in the form of protrusions.

The supporting surface of the protrusions is inclined relative to the horizontal by 1-3 °.

Data showing the effect of the inclination angle (when the rollers are displaced by 0.2 length) of the supporting surfaces on their

(resistance, are given in table.1.

The rollers in the separators are offset from one another by 0.2-0.5 of their length.

The data, allowing to judge about the effect of the displacement of the rollers on the resistance of the runners, are given in Table 2, (with the sizes of the rollers cTs1 12 "12 mm).

The device works as follows.

By means of a drive, the movable sleeve 5 with plate 2 and glass-collector 3 is moved relative to stationary plate 1, resting on rollers 8 enclosed in separator 9. Movement is made along the rails m 10 and 11 to the Closed position.

The use of the proposed invention will reduce the load on the extreme zones of the runners, which accordingly will lead to an increase in their durability and an increase in the service life.
