Problems solved by technology

[0002] In iron and steel smelting production, liquid steel (iron) slag is easy to adhere to the slag pot and slag pan during transportation and turning over, making it difficult to dump slag
Steel (iron) slag will stick to the inner wall of the slag tank after thickening, which increases the difficulty of removal. Some use cranes to hit and shake, or cut and break the slag, which not only wastes manpower, material and financial resources, increases production costs, but also easily damages the slag. tank, reducing the service life of the slag tank container, there are potential safety hazards, and accidents occur from time to time
[0003] Although the prior art adopts measures such as spraying graphite powder on the inner wall of the slag tank and laying lime clay powder or coal cinder, red bricks in the slag tank, there are still defects such as incomplete deslagging and poor detachment effect. Solve the problem of steel (iron) slag sticking to the slag tank

Abstract

The invention provides a formulation for the raw materials of a steel slag tripping agent, which comprises a predetermined amounts of dolomite, alta-mud, clay, tripolyphosphate, silicon micronized quartz powder, sodium carboxymethylcellulose, graphite and boric acid, the agent can be used for the realization of one time slag-peeling of the slag pots at high and low temperature.

Description

technical field [0001] The invention belongs to the technical field of iron and steel smelting, and relates to a raw material formula of a steel (iron) slag release agent. Background technique [0002] In iron and steel smelting production, liquid steel (iron) slag tends to adhere to the slag pot and slag pan during transportation and overturning, making it difficult to dump the slag. Steel (iron) slag will stick to the inner wall of the slag tank after thickening, which increases the difficulty of removal. Some use cranes to hit and shake, or cut and break the slag, which not only wastes manpower, material and financial resources, increases production costs, but also easily damages the slag. tank, reducing the service life of the slag tank container, there are potential safety hazards, and accidents occur from time to time. [0003] Although the prior art adopts measures such as spraying graphite powder on the inner wall of the slag tank and laying lime clay powder or cind...
