FIG. 2 is a diagram illustrating a usage status of a slag stopper of a converter according to an embodiment of the present invention;
labeled as: 1. a converter slag stopper; 2. a clamping rod; 3. asbestos cloth; 4. a circular tube; 5. the upper end surface of the slag stopping plug; 6. a slag stopper; 7. a support bar; 8. a steel tapping hole; 9. a slag stopping vehicle; 10. and (5) repairing materials.
Detailed Description
The present invention will be described in detail with reference to the following embodiments in order to fully understand the objects, features and functions of the present invention, but the present invention is not limited thereto.
Referring to fig. 1, the utility model provides a pair of converter pushing off slag stopper comprises supporting rod 2, pushing off slag stopper 6, pipe 4 and bracing piece 7 etc. and pushing off slag stopper 6 is the hexagonal prism table structure of invering, and the upper and lower terminal surface of pushing off slag stopper 6 is hexagonal steel sheet structure respectively, and the lateral wall of pushing off slag stopper 6 is isosceles trapezoid steel sheet structure, and the hexagonal steel sheet of upper and lower terminal surface forms the pushing off slag stopper 6 of the hexagonal prism table structure of invering with six isosceles trapezoid steel sheet welding. The steel plate is made of waste steel of a steel mill, and the manufacturing cost is low.
The upper end face 5 of the slag stopping plug is fixedly connected with the lower end of the clamping rod 2 and the lower end of the circular tube 4 respectively, the circular tube 4 is sleeved on the outer side of the clamping rod 2, and the space formed by the clamping rod 2, the circular tube 4 and the upper end face 5 of the slag stopping plug is filled with asbestos cloth 3, so that the repairing material is prevented from entering, and the raw material waste is reduced. The lower end surface of the slag stopper 6 is fixedly connected with the upper end of the support rod 7.
Referring to fig. 2, when a converter tap hole 8 is repaired by using the converter slag stopper 1, the converter slag stopper 1 is first clamped by the slag stopper car 9 and inserted into the tap hole 8 of the converter, and at this time, the lower portion 1/3 of the terrace of the slag stopper 6 is located in the tap hole, and the remaining portion 2/3 of the terrace is exposed outside (about 200 mm) the tap hole 8, and the slag stopper 6 seals the upper edge of the tap hole 8 to prevent the repair material 10 from entering the tap hole 8. And then a circle of repairing material 10 is filled around the exposed slag stopper 6, the height of the repairing material 10 is about 50mm, the baking is completed, the slag stopper 6 and the repairing material 10 are sintered together after the baking is completed, the repairing material is higher than the steel tapping hole, and the repairing material is firstly flushed by molten steel during use, so that the service life of the steel tapping hole is prolonged. And finally, after the furnace is supplemented, adding molten iron and scrap steel into the converter for smelting, and directly melting the converter slag stopper 1 by using high-temperature molten iron through shaking the converter without influencing tapping operation.
Because the height of the slag stopper of the converter of the utility model is exposed 2/3 (about 200 mm) at the tap hole, the repairing mass can not enter the tap hole 8; and the clamping rod 2, the supporting rod 7 and the round pipe 4 of the converter slag stopper 1 are made of steel materials, can be directly melted by high-temperature molten iron, and do not influence tapping operation. Meanwhile, the converter slag stopper 1 is made of waste steel of a steel mill, so that the manufacturing cost is low, the operation is simple and convenient, and the spare part consumption and the production cost are reduced.
Finally, it is noted that: the preferred embodiments of the present invention have been shown and described, and it will be understood that modifications and variations may be made by those skilled in the art without departing from the scope of the invention.
