Drawings
FIG. 1 is a schematic view of a slag stopper for tapping from a steel converter;
in the drawings, the reference numerals denote: 1. the device comprises a winch, 2, a manual crank, 3, a support rod, 4, a first thick steel wire rope, 5, a converter, 6, a steel tapping hole, 7, a slag blocking cone, 8, a thin steel wire rope, 9, a second thick steel wire rope, 10, a limit baffle, 11 and a movable supporting seat.
Detailed Description
The utility model is further illustrated by the following figures and examples.
The slag stopping device for tapping of the steel converter comprises a winch 1, a manual crank 2, a support rod 3, a first thick steel wire rope 4, a slag stopping cone 7, a thin steel wire rope 8, a second thick steel wire rope 9, a limiting baffle 10 and a movable support seat 11; the slag blocking cone is made of refractory materials, the specific gravity of the slag blocking cone is between that of slag and molten steel, and due to the difference of the specific gravity, the slag blocking cone is suspended above the molten steel and is positioned in the slag; when the converter 5 is turned over, the molten steel flows out along the steel outlet 6, and the slag blocking cone blocks the steel outlet as the liquid level of the molten steel is lowered, so that the molten steel flows out completely, and slag is blocked in the converter.
The steel tapping slag stopping device of the steel converter is characterized in that the position of the limiting baffle 10 is predetermined according to the position of the steel tapping hole 6, and when the movable supporting seat 11 moves to the position of the limiting baffle, the slag stopping cone can be ensured to be positioned right above the steel tapping hole.
The slag stopping device for tapping of the steel converter is characterized in that the right end of the support rod 3 is provided with a 3-4 m fireproof layer 12.
The working process of the steel tapping slag stopping device of the steel converter is described as follows: when the converter needs to tap steel, the converter is turned over, the movable supporting seat 11 is pushed to the limit baffle 10 at the moment and then stopped, the manual crank 2 is shaken to drive the winch 1 to rotate, the first thick steel wire rope 4 moves rightwards under the action of the gravity of the slag blocking cone 7, and the thin steel wire rope 8 also moves rightwards gradually; when the thin steel wire rope is exposed out of the rectangular groove below the support rod 3, the thin steel wire rope is melted in a short time due to the action of high temperature in the furnace, and the slag blocking cone falls into molten steel; because the guide rod is arranged below the slag blocking cone, and the diameter of the guide rod is far smaller than that of the steel tapping hole 6, the slag blocking cone is easy to insert into the steel tapping hole.
