Problems solved by technology

[0006] Spray coating on the slag basin and slag pot: the thickness of the sprayed coating layer is limited, the ability to resist high-temperature molten steel erosion is poor, and it cannot achieve the effect of anti-sticking steel, and the use is limited, so only thermal spraying can be used; for cold slag basins 1. After the slag tank is sprayed, undried liquid spray paint is easy to accumulate at the bottom, and it will explode when it encounters high-temperature molten steel, which will affect production safety and make this type of method not very applicable.

Embodiment Construction

[0024] The present invention will be further described below, preferred embodiment of the present invention is:

[0025] The raw material of the overflow steel channel ramming material in this embodiment is high-quality quartz sand (0.2-2mm), high-alumina bauxite clinker powder (-80 mesh), zircon sand powder (-80 mesh), kaolin (-80 mesh) , Phosphorus flake graphite powder (-200 mesh), the adhesive uses ethyl silicate aqueous solution, boric acid is used as a sintering agent, and a small amount of tar is added to enhance the plasticity and ramming of the material; its weight percentage is: quartz sand 60% , High alumina bauxite clinker powder 6%, zircon sand powder 15%, kaolin 5%, phosphorus flake graphite 4%, ethyl silicate aqueous solution 4%, boric acid 1%, tar 2%, water 3%;

[0026] 1) Add quartz sand, high-alumina bauxite clinker powder and zircon sand powder into the mixer according to the ratio and mix at low speed for 5 minutes;

[0027] 2) Add kaolin, phosphorus flake...

Abstract

The invention provides an anti-steel-sticking treatment method of slag basins and slag tanks by using an overflow steel tank ramming material. The overflow steel tank ramming material comprises the following components by weight percent: 55% to 70% of quartz sand, percent, 5% to 10% of high alumina bauxite clinker powder, 12% to 22% of zircon sand powder, 4% to 8% of kaolin, 3% to 5% of flake graphite, 3% to 6% of ethyl silicate aqueous solution, 0.8% to 1. 6% of boric acid, 2% to 6% of tar and 3% to 6% of water. The overflow steel tank ramming material is smeared on the inner walls of the slag basins and the slag tanks, so that the overflow steel tank ramming material has good tamping performances and smearing performances, has the good characteristics of high temperature resistance, erosion resistance, easiness for tamping, no burst, non-baking, makes up for the defects of application of traditional refractories to the slag basins and the slag tanks, realizes the stable and smooth operation of the slag basins and the slag tanks on a steelmaking line, and has a greater economic value.

Description

technical field [0001] The invention relates to the technical field of anti-sticking steel treatment of slag pots and slag pots for steelmaking production, in particular to a method for treating anti-sticking steel of slag pots and slag pots by using ramming material overflowing a steel tank. Background technique [0002] Slag pots and slag pots are containers used to hold steel slag and molten steel in steelmaking production. They are one of the indispensable equipment in the steelmaking production system, and their operation is synchronized with the steelmaking line. [0003] For a long time, steelmaking plants have used slag pots and slag tanks to hold high-temperature tail steel and high-temperature molten steel scrap, so that the slag pots and slag tanks often appear sticky and welded by molten steel. The tank scrap rate is high, and there is great pressure on the smooth operation of the slag basin and slag tank. The traditional way to solve the problem of sticking ste...
