Problems solved by technology

The ladle with sticky slag is difficult to clean, and safety accidents are prone to occur
[0003] After the existing anti-adhesive slag spray coating is sprayed, the anti-adhesive isolation protective film formed has a large thickness and low adhesion, which is easy to fall off and has poor protection effect on iron ladles.
Furthermore, the production cost of spray coating is high and the economic benefit is poor.

Abstract

The invention provides an anti-stick slag spray coating for iron clad, which comprises the following components by weight: 70-80% of aggregate, 16-25% of binder, 1-10% of anti-stick slag functional additive, and external additives 0.01-1%, the binder is a composite binder, including microsilica, Portland cement, water glass powder and bentonite. When using, firstly prepare the mixture according to the above weight ratio, secondly add water with a weight ratio of 5 to 8% of the mixture under strong stirring, and finally spray it onto the iron-clad anti-sticking slag position through a spray gun. Compared with the prior art, the anti-stick slag spray coating for iron ladle proposed by the present invention has high strength, good anti-slag effect, strong slag erosion resistance and oxidation resistance, and good thermal shock resistance. The use of waste skateboard recycled material as the main component of the aggregate of the anti-stick slag spray coating greatly reduces the production cost of the anti-stick slag spray coating, and the comprehensive benefit is high.

Description

technical field [0001] The invention relates to the technical field of spray paint, in particular to an anti-sticking slag spray paint for iron ladle and its application method. Background technique [0002] The molten iron is poured into the converter through the reverse transport of the ladle. During the use of the ladle, the brick lining is eroded by high temperature, and it is easy to stick to slag and iron, which shortens the service life of the ladle. There are two main methods of sticking slag and iron in the ladle: one is that the molten iron and slag are directly fused with the castable along the ladle, react with each other, and finally merge into one; the other is that the molten iron slag solidifies in the Pack along the castable. The ladle with sticky slag is difficult to clean up, which is prone to safety accidents. [0003] After the existing anti-adhesive slag spray coating is sprayed, the anti-adhesive isolation protective film formed has a large thickness...
