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

Embodiment 2

[0014] Formulation example 2 of the steel slag release agent of the present invention uses the following raw materials in parts by weight: dolomite 80, bentonite 30, clay 30, sodium tripolyphosphate 5, silicon powder 5, sodium carboxymethyl cellulose 5, graphite 5, boric acid 5 . Prepare and apply according to the method of Example 1.

[0015] Formulation Example 3 of the steel slag release agent of the present invention uses the following raw materials in parts by weight: Dolomite 50, bentonite 20, clay 20, sodium tripolyphosphate 3, silicon powder 3, sodium carboxymethyl cellulose 3, graphite 3, boric acid 3 . Prepare and apply according to the methods of the above-mentioned examples.

[0016] Formulation Example 4 of the steel slag release agent of the present invention may also use the following parts by weight of raw materials: In the formulation of Example 1, 0.5 sodium silicate and 5 magnesium chloride are added.

Embodiment 5

[0017] Formulation Example 5 of the steel slag release agent of the present invention may also use the following raw materials in parts by weight: In the formulation of Example 2, sodium silicate 5 and magnesium chloride 10 are added.

[0018] Formulation Example 6 of the steel slag release agent of the present invention may also use the following parts by weight of raw materials: In the formulation of Example 3, sodium silicate 3 and magnesium chloride 7 are added.

[0019] Prepare and apply according to the methods of the previous examples.

[0020] The above formulas of Examples 1-6 are all obtained through repeated trials and improvements by the inventor. Small batches of samples have been tried on site by multiple users, and satisfactory results can be obtained, and liquid steel slag can be better prevented. The iron slag adheres to the inner wall of the slag tank container, and there is no need to use the crane to hit the slag, no need to cut and break the slag, realize a co...

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 stick to the slag pot of the slag pot during transportation and overturning, making it difficult to discharge the slag. The thick steel (iron) slag will stick to the inner wall of the slag tank, which increases the difficulty of removal. Some use cranes to hit and throw, or cut and break the slag, which not only wastes manpower, material and financial resources, increases production costs, but also easily damages the slag The tank reduces the service life of the slag tank container, and there are hidden safety hazards, and accidents occur from time to time. [0003] Although the prior art has adopted measures such as spraying graphite powder on the inner wall of the slag tank, laying lime clay powder or coal s...
