Description
Technical field
The present invention relates to technical field of refractory materials, a kind of hot semidry method spray paint of mixed iron blast is related in particular to.
Background technology
Mixed iron blast is the elevated temperature vessel of steel mill storage molten iron, homogenizing hot metal composition and temperature, while having adjustment to produce
Save the function of gathering.Therefore, the long-life of metal mixer liner is common, the unremitting pursuit of each steel mill.There is mixed iron blast the country at present
About 500, capacity has 300 tons, 600 tons, 900 tons, 1300 tons.
Before 2000, the inner lining material of mixed iron blast is fairly simple --- magnesia brick, clay brick, high-alumina brick.In 2000
More than ten years into 2014 are the stages that China's steel industry is developed rapidly, and iron and steel output becomes 800,000,000 from 1.5 hundred million tons
Ton, refractory material yield becomes 29,000,000 tons from 12,000,000 tons.Yield, kind and the construction technology of refractory material have also been obtained very
Big development.
The inner lining material of mixed iron blast has high-alumina brick, corundum brick, corundum-mullite brick, aluminum silicon carbide brick, corundum-mullite to pour
Material feeding, aluminium silicon carbide castable, high-strength light castable etc., build furnace technology also from single brick technological development to brick work
Skill, mixing furnace building process, integrated poured three kinds of technique are simultaneously deposited.
No matter which kind of technique and material make the mixed iron blast of liner, use as a servant the later stage in stove, slag line and tapping hole position often exist
There is corroding more serious band in a certain height.Blowing out is repaired, taken time and effort, and is worked under hard conditions and dangerous, upsets follow-up
STEELMAKING PRODUCTION section gathers.In this case, maximally effective method, which is not blowing out, sprays repairing, i.e., hot spraying.Spraying repairing can divide again
For flame-spraying, semidry method spraying, wet spray.Flame spray device is complicated, of a high price；Wet spray equipment and requirement
It is more complicated.Consider, semidry method spraying is the most feasible.
It is used as the hot spray paint of mixed iron blast, it is necessary to possess following performance：Adhesion property is good, rebound rate is low；Inside material
Moisture is heated not to concentrate a large amount of volatilizations；Resistant to corrosion, scour resistance are good.In the market spray paint aluminous cement consumption all compared with
It is high（More than 15%）, it is also possible that but for cold conditions spraying due to largely being absorbed water in aluminous cement hydration process, aquation when being heated
Product is largely dehydrated before 350 DEG C, causes material avalanche, is not particularly suited for hot spraying, and high-temperature behavior is also poor, and spray is once
It is only capable of using first quarter moon or so.
The content of the invention
It is an object of the invention to the defect for above-mentioned prior art, there is provided a kind of hot semidry method spraying of mixed iron blast
Expect, the adhesiveness after the hot semidry method spray paint use of the mixed iron blast is good, rebound rate is low, material resistant to corrosion, scour resistance are good,
Moisture does not concentrate a large amount of volatilizations.
To achieve these goals, the technical scheme is that：
A kind of hot semidry method spray paint of mixed iron blast, including bauxite, silicon ash, 95 magnesia and soft clay；95 magnesia is
200 targeted fine powders；The mass ratio of the silicon ash, 95 magnesia and soft clay is 3：6~9：3~6, the silicon ash, 95 magnesia and
The gross mass of soft clay and the mass ratio of bauxite are 2~18：82~88.
As the improvement to above-mentioned technical proposal, the bauxite by the mm of particle diameter 0.21~5 bauxite aggregate and 200
Purpose bauxite powder is mixed, and the mass ratio of the bauxite aggregate and bauxite powder is 64：18~24.
As the improvement to above-mentioned technical proposal, the hot semidry method spray paint of mixed iron blast also includes anti-bounce-back agent, institute
State the STABEN that anti-bounce-back agent is BASF AGTMSeries of products, the addition of the anti-bounce-back agent and bauxite, silicon ash, 95
Magnesia, the mass ratio of the total amount of soft clay are 0.15：100.
As the improvement to above-mentioned technical proposal, the hot semidry method spray paint of mixed iron blast also includes water reducer, is subtracted
Aqua is the one or more in Quadrafos, HAD, FS series, the water reducer and bauxite, silicon ash, 95 magnesia, soft clay
Total amount mass ratio be 0.2：100.
In above-mentioned material, bauxite is containing alundum (Al2O3) 80.02%, containing silica 1 3.07%, containing di-iron trioxide
1.3%th, containing titanium dioxide 2.88%, containing magnesia 0.36%；Silicon ash is containing silica 94.74%, containing di-iron trioxide 0.1%；95 magnesium
Sand contains magnesia 95.42%, containing calcium oxide 1.83%, containing di-iron trioxide 0.74%, containing silica 2.01%；Soft clay contains three
Al 2 O 33.14%, containing di-iron trioxide 1.41% .42% containing silica 1.
Compared with prior art, the present invention has the advantages and positive effects of：
The hot semidry method spray paint of mixed iron blast of the present invention, after use, the spray paint is under low-temperature condition, bauxite, silicon ash, 95
Magnesia and soft clay form MgO-SiO at low temperature2-H2Olivine is generated under O combination systems, high temperature, material is substantially improved
High-temperature behavior, meets the good performance requirement of material resistant to corrosion, scour resistance；The soft clay of addition is plastic raw material, and is drawn
Enter a certain amount of anti-bounce-back agent, enable material adhesion very well, rebound rate is less than 5%, meets the property that adhesiveness is good, rebound rate is low
It can require；This spray paint MgO-SiO2-H2O systems replace alumina cement, material was only discharged Free water, nothing before 700 DEG C
Crystal-water discharge.Meet the moisture inside material and do not concentrate the performance requirement largely volatilized.
Its MgO-SiO2-H2O system hydration reactions are as follows：
3MgO+2SiO2+2H2O=3MgO.2SiO2.2H2The 700-800 DEG C of dehydration of O serpentines
3MgO+4SiO2+H2O=3MgO.4SiO2. H2The 900-1100 DEG C of dehydration of O talcums
3MgO.2SiO2.2H2O+ MgO =2M2S+2H2O
3MgO.4SiO2. H2O+ MgO=2M2S+2SiO2+H2O
Show on different steel mill mixed iron blasts using result, the hot half-dried spray paint adhesion property developed is good, rebound rate
Less than 3%；Moisture inside material is heated not to concentrate a large amount of volatilizations, spraying no longer to be come off after adhering to, thickness is more than 200mm；
Resistant to corrosion, scour resistance are good, spray once can be used more than 3 months.
