Abstract
The invention provides molten-slag-resistant spray paint for a ladle. The molten-slag-resistant spray paint comprises the following components in percentage by weight: 70-80 percent of aggregate, 16-25 percent of a bonding agent, 1-10 percent of a molten-slag-resistant functional additive and 0.01-1 percent of an additional additive, wherein the bonding agent is a composite bonding agent, and comprises silica powder, silicate cement, sodium silicate powder and bentonite. A method for applying the spray paint comprises the following steps: firstly, preparing a mixture in the weight ratio; secondly, adding water in an amount of 5-8 percent based on the weight of the mixture under strong stirring; and lastly, spraying the mixture onto a molten slag resisting position on the ladle through a spray gun. Compared with the prior art, the molten-slag-resistant spray paint provided by the invention has the advantages of high strength, high molten slag resistance, molten slag erosion resistance, oxidation resistance and high thermal shock resistance. Moreover, a waste sliding plate reclaimed material is taken as a main component for the aggregate of the molten-slag-resistant spray paint, so that the production cost of the molten-slag-resistant spray paint is lowered greatly, and high comprehensive benefit is achieved.
Description
Technical field
The present invention relates to spray material technical field, refer to especially a kind of iron bag slag adhesion spray material and using method thereof.
Background technology
Molten iron is blended into converter by having bad luck of hot metal ladle, and hot metal ladle in use bricking is subject to high temperature erosion, and easily dry slag, glues iron, has shortened the work-ing life of hot metal ladle.The sticky iron of hot metal ladle dry slag mainly contains two kinds of modes: first molten iron and slag directly and iron handbag merge mutually along mould material, react each other, finally combine together; Its two be because temperature reduce, molten iron slag be set in bag along in mould material.The hot metal ladle of dry slag is difficult to cleaning, and security incident easily occurs.
After existing slag adhesion spray material spraying, the antiseized insulation blocking thicknesses of layers of formation is large and adhesive power is low, is easy to come off, to the protection weak effect of iron bag.Moreover spray material production cost is high, deficiency in economic performance.
Summary of the invention
The present invention proposes a kind of iron bag slag adhesion spray material and using method thereof, for solving the problems referred to above of background technology.
Technical scheme of the present invention is achieved in that
A kind of iron bag slag adhesion spray material, comprise the component of following weight percent: aggregate 70～80%, bonding agent 16～25%, slag adhesion functional additive technique thing 1～10%, outer doping 0.01～1%, bonding agent is combined binder, comprises silicon powder, silicate cement, water glass powder and wilkinite.
Selection of the present invention is reasonable, ratio optimization, and the slag adhesion spray material intensity that makes is high and have stronger oxidation-resistance, anti-slag corrosion and a good thermal shock resistance; By homemade combined binder, reach the object of sprayed coating rapid solidification, improved the intensity of slag adhesion spray material, make it firmly be attached to bag along on mould material and hot metal ladle slag line, form the nonmetal isolation protection film of one deck, effectively protected hot metal ladle furnace lining; In bonding agent, add wilkinite and silicon powder and (claimed again silicon powder, silicon ash, there is the features such as high workability, low water storage, high-compactness and high strength), improve the mixing uniformity of spray material, made slag adhesion spray material there is good mobility, convenient construction.
Preferably, comprise the component of following weight percent: aggregate 76～80%, bonding agent 16～25%, slag adhesion functional additive technique thing 1～6%, outer doping 0.2%.
Preferably, in bonding agent, the weight percent of each component is: silicon powder 10～20%, silicate cement 10～20%, water glass powder 30～50% and wilkinite 20～40%, in bonding agent, the granularity of each component is all less than 200 orders.
Preferably, aggregate comprises the component of following weight ratio: useless slide plate reworked material 45～65%, three grades of bauxitic clays 20～40% and quartz 10～30%, in aggregate, the granularity of each component is 0.1～3mm.
By selecting useless slide plate reworked material (such as useless slide brick, comprise the fire-resistant useless brick of aluminium silicon carbide, the fire-resistant useless brick of aluminium carbonaceous, the fire-resistant useless brick of magnesium carbonaceous etc.) as the main component of the aggregate of slag adhesion spray material, the production cost that greatly reduces slag adhesion spray material, comprehensive benefit is higher.
Preferably, slag adhesion functional additive technique thing comprises amorphous graphite, and amorphous graphite granularity is not more than 200 orders.
Amorphous graphite claims again micro crystal graphite, there is good coating property and lubricity, well to cast releasing agent, graphite for the wetting angle of iron liquid much larger than 90 °, by selecting the amorphous graphite of suitable particle size as slag adhesion functional additive technique thing, make slag adhesion spray material have good slag adhesion function, result of use is good.
Preferably, external additive comprises tripoly phosphate sodium STPP, certainly other phosphoric acid salt also can, such as Sodium hexametaphosphate 99, they are all to use as water reducer, can reduce the water consumption of spraying application.
The invention allows for the using method of above-mentioned iron bag slag adhesion spray material:
First obtain mixture according to above-mentioned weight ratio preparation, secondly under strong stirring, add mixture weight than 5～8% water, finally arrive the position of iron bag slag adhesion by spray gun spraying, under equipment cold conditions and hot condition, all can carry out slag adhesion and process construction, after construction, can come into operation immediately.
The iron bag that the present invention proposes is high and have stronger oxidation-resistance, anti-slag corrosion and good thermal shock resistance by slag adhesion spray material intensity, can form the antiseized isolation protection film that adhesive power is strong when use, effective to the protection of iron bag.Moreover starting material sources is wide, cost is low, can accomplish the comprehensive utilization of waste and old resource, good in economic efficiency, market outlook are good.
