Embodiment 1

[0024] Prepare 100Kg iron ladle anti-sticking slag smear, the raw material that adopts and weight percentage thereof are as follows:

[0025]

[0026]

[0027] Accurately weigh the above-mentioned raw materials, pour them into a mixer, mix evenly, pack them in bags after discharge, conduct random inspection, and put them into storage to obtain the required anti-sticking slag smear for molten iron tanks.

Embodiment 2

[0029] Prepare 100Kg iron ladle anti-sticking slag smear, the raw material that adopts and weight percentage thereof are as follows:

[0030]

[0031] Accurately weigh the above-mentioned raw materials, pour them into a mixer, mix evenly, pack them in bags after discharge, conduct random inspection, and put them into storage to obtain the required anti-sticking slag smear for molten iron tanks.

Embodiment 3

[0033] Prepare 100Kg iron ladle anti-sticking slag smear, the raw material that adopts and weight percentage thereof are as follows:

[0034]

[0035]

[0036] Accurately weigh the above-mentioned raw materials, pour them into a mixer, mix evenly, pack them in bags after discharge, conduct random inspection, and put them into storage to obtain the required anti-sticking slag smear for molten iron tanks.

[0037] Specifically, in a 200-ton molten iron tank where the slag line and the edge of the tank are prone to slagging, an industrial comparison experiment was carried out using the smear of the present invention and the currently commercially available smear. The experimental results show that the use of the smear of the present invention The construction of the material smearing process is simple. After the smearing is completed, the molten iron tank has excellent anti-slag performance, high sintering strength, and low maintenance cost. It has strong market competitiven...

Abstract

The invention discloses a slag anti-adhesion coating for a hot metal ladle. The slag anti-adhesion coating consists of the following components in percentages by weight: 35-70wt% of carbonaceous fireproof waste brick A-level materials, 10-35wt% of waste high-aluminum brick materials, 5-30wt% of black silicon carbide, 3-8wt% of aluminous cement, 3-8wt% of Guangxi white clay, 0.1-2wt% of carboxymethyl cellulose sodium, 0.1-1wt% of sodium tripolyphosphate, 0.1-1wt% of organic explosion-proof fibers, and 0.01-1wt% of quick lime. According to the slag anti-adhesion coating for the hot metal ladle disclosed by the invention, the preparation process is simple; besides, in the construction project of slag anti-adhesion treatment for the hot metal ladle, the slag anti-adhesion coating has the characteristics of being simple in construction, excellent in slag anti-adhesion property, high in sintering intensity, low in cost and the like, and is obvious in economic benefit and social benefit.

Description

technical field [0001] The invention relates to the technical field of refractory materials for iron and steel metallurgy, in particular to an anti-sticking slag smearing material for molten iron tanks. Background technique [0002] In the iron and steel metallurgy industry, the hot metal tank is an important equipment for collecting and transporting molten iron in the blast furnace and adding iron in the steel plant, and has a long service life. However, in the process of use, slag and iron slag are easily formed on the slag line of the molten iron tank and along the tank edge, and gradually thicken, which seriously affects the production efficiency and production safety of iron and steel enterprises, and slag cleaning must be carried out. However, the slag cleaning process seriously damaged the refractory material along the slag line and the tank, which not only affected the normal turnover of the molten iron tank, but also reduced its service life. Therefore, it is neces...
