High temperature separating material for preventing cinder and steel from staining to cinder ladle

Abstract

The invention makes public a kind of high temperature separating material which can prevent dregs from adhering the dregs pot. The material includes 30~50 units of dolomite, 30~45 units of bentonite, 18~28 units of clay, 1.0~2.5 units of trimer sodium phosphate, 0.5~3.0 units of carboxymethyl cellulose and 135~220 units of water in proportion of weight. All water-fast particles' size should not lesser than 180 eyes. And about 0.5~5 units of black lead can be joined in the material. The material has good property of high temperature, dregs proof, and anti-strip. It can prevent the pot from being dregs adhered effectively, so it can make sure turning dregs automatically and high velocity of the pot. Adhering degree of the material is moderate, and no deposition and delamination in 72 hours. The material has good working performance.

Description

technical field [0001] The invention relates to the protection technology of a slag tank container for storing hot slag and residual steel in the metal smelting process, in particular to a high-temperature separation material for preventing the slag tank from sticking to slag and steel. Background technique [0002] When iron and steel enterprises produce various metal products, they will inevitably produce various high-temperature furnace slags and steel slags. For example, 8-10% slag can be produced in the oxygen converter smelting process. Usually, these molten steel slags are poured into the slag tank and then transported to the slag yard to be turned out for processing. The slag pot is actually an intermediate transition metal container. In order to reduce damage to the slag tank, ensure safety, speed up turnover, and stabilize production, a layer of high-temperature-resistant separation material must be coated on the inner wall of the slag ...

AI Technical Summary

Problems solved by technology

At present, most of the ordinary high-temperature separation materials (also known as high-temperature coatings) used in slag tanks by domestic metallurgical iron and steel enterprises are prone to sticking to slag and steel.

When the slag tank is overturned, the slag and steel slag are often not poured out smoothly, and people are forced to use mechanical methods or oxygen melting and cutting methods to remove the residual steel, which consumes a lot of manpower and material resources, and directly affects the steel production process. time rhythm
