Description
Technical Field
The invention relates to the technical field of preparation of blast furnace iron runner protective materials, in particular to an iron runner working lining anti-oxidation coating and a preparation method thereof.
Background
A blast furnace tapping channel, also called as an iron channel, is a channel for leading out high-temperature molten iron or molten slag and is also an important component of a blast furnace. The inner lining of the blast furnace tapping hook generally comprises a permanent lining and a working lining, and the current working lining mainly comprises two types: one is casting material integral casting, and the other is masonry by high-alumina brick or clay brick.
The working layer poured by the iron runner castable contains more water, and needs to be baked by blast furnace gas, and the maximum baking temperature of the gas can reach 677 ℃. The carbon raw material in the casting material is basically amorphous carbon, and the carbon raw material can be oxidized in an oxidizing atmosphere at the baking temperature, so that the thermal shock resistance stability and the structural strength of the iron runner lining are poor, the service life of the iron runner lining is finally shortened, and the positive output of iron is influenced.
Disclosure of Invention
The invention aims to provide the anti-oxidation coating for the working lining of the iron runner, which can effectively reduce the oxidation degree of carbon in the casting material of the working lining of the iron runner, thereby improving the working performance of the lining of the iron runner and prolonging the service life of the lining of the iron runner. The invention also aims to provide a preparation method of the anti-oxidation coating for the working lining of the iron runner.
The purpose of the invention is realized by the following technical scheme:
an anti-oxidation coating for an iron runner working lining is characterized by comprising the following components in parts by weight:
by adopting the technical scheme, the wood glue is used as the adhesive of the coating, the water is used as the wetting agent, the granular and powdery materials in the coating are connected, and the coating has good adhesion, can be firmly adhered to the surface of the working lining, is not easy to fall off and plays a good protection role. Brown sugar is used as an auxiliary adhesive, and has the effects of thickening and increasing the adhesive force. The light-burned magnesia is used as a filler binder, and the component of the light-burned magnesia is MgO, and the MgO has the characteristic of high fire resistance and insulation, thereby improving the thermal stability and the high temperature resistance of the coating.
It should be noted that carbon black is a loose, light and extremely fine black powder, and has a high specific surface area, and therefore has higher reactivity than the carbon raw material in the castable. When the working lining is baked by blast furnace gas, the carbon black preferentially reacts with oxygen, so that the oxidation degree of the carbon raw material in the castable in the baking stage is reduced, and the carbon raw material is better protected from being oxidized, thereby improving the corrosion resistance reduction, the thermal shock stability and the spalling resistance of the castable working lining, and finally prolonging the service life of the iron runner lining.
Further setting the following steps: also comprises 30-35 parts by weight of coke powder.
By adopting the technical scheme, the coke powder is the coke powder with the particle size of less than 10mm generated in the coke production process of the coke oven, has strong reducibility, and can also play a role in preferential oxidation so as to protect the carbon raw material in the castable. In addition, because the solubility of the carbon black in the water solvent is poor, only a small amount of carbon black can be dissolved in the coating, so that the protection effect of the carbon black is incomplete; the coke powder and the hydrosolvent have better intermiscibility, so that the problem of insufficient carbon black can be solved, and a more thorough protection effect on the castable working lining is further achieved.
Further setting the following steps: also comprises 10-15 parts by weight of aluminum powder.
By adopting the technical scheme, the aluminum powder is a metal simple substance with extremely strong reducibility, and the aluminum powder and oxygen in the air generate oxidation-reduction reaction under the heating and baking conditions to generate a compact alumina film, so that the oxygen in the air is reduced, the oxidation reaction of carbon raw materials in the castable is inhibited, and the compact alumina film can further obstruct the oxygen from oxidizing the carbon raw materials in the castable, thereby having double protection effect on the carbon raw materials.
Further setting the following steps: also comprises 20-30 parts of ammonium acetate.
By adopting the technical scheme, the ammonium acetate is a weak acid weak base salt, has good water solubility, and simultaneously has an ionization hydrolysis reaction with the ionization reaction formula of CH3COONH4＝CH3COO-+NH4 +(1) The hydrolysis reaction comprises the following steps:
and
the light-burned magnesium oxide is hardly soluble in water and ethanol, but is easily soluble in acid and ammonium salt, and as can be seen from the formulas (2) and (3), the ammonium ion in ammonium acetate is hydrolyzed to produce H+Light-burned magnesium oxide and H formed by hydrolysis+Reacting to form water-soluble Mg2+And further, the solubility of the light-burned magnesium oxide in the coating is increased.
When the blast furnace gas is used for baking the working lining, the temperature of the working lining is gradually increased, the aluminum powder is oxidized to release heat, and the hydrolysis reaction of the formulas (2) and (3) is an endothermic reaction, so that the hydrolysis equilibrium of the formulas (2) and (3) is continuously shifted to the right, and H is enabled to be generated+Continuously dissolve more Mg2+,Mg2+Then continuously hydrolyzing with the formula (2) to generate OH-Formation of Mg (OH)2And (4) precipitating. Mg (OH)2Is an excellent flame retardant, and when the temperature of a working lining reaches 380 ℃, Mg (OH)2The magnesium oxide solid is isolated from oxygen on the surface of the working lining, so that the carbon raw material in the casting material of the working lining is further protected from being oxidized, and the service life of the working lining is prolonged.
Further setting the following steps: the wood adhesive adopts polyvinyl acetate adhesive.
By adopting the technical scheme, the polyvinyl acetate adhesive is formed by polymerizing vinyl acetate, has high relative molecular mass, has high solution viscosity and excellent mechanical strength, can play a firm adhesion effect when used as the adhesive, and improves the bonding strength of the coating and the surface of the working lining.
Further setting the following steps: the viscosity of the polyvinyl acetate adhesive is more than or equal to 500cps, the pH value is 4-7, and the solid content is more than or equal to 40%.
Further setting the following steps: the carbon black has a fixed carbon content of 99.8% and a particle size d1 of 280 nm.
Further setting the following steps: the fixed carbon content of the coke powder is 90%, and the granularity d2 is more than 0 and less than or equal to 1nm and less than or equal to d 2.

A preparation method of an anti-oxidation coating for an iron runner working lining comprises the following steps:
s1, dissolving ammonium acetate in water to form an ammonium acetate aqueous solution;
s2, stirring the wood adhesive at a speed of 120r/min, and sequentially adding brown sugar, light-burned magnesium oxide, aluminum powder, coke powder and carbon black while stirring to form a primary mixed material;
and S3, adding the ammonium acetate aqueous solution prepared in the step S1 into the primary mixed material prepared in the step S2 while stirring, and uniformly stirring to obtain the finished coating.
