Abstract
Resist the invention discloses a kind of high temperature and invade wear-resistant castable, include the component of following mass percent：Bauxite aggregate 50 ~ 70%, corundum aggregate 10 ~ 20%, white fused alumina fine powder 5 ~ 15%, chromium oxide 3 ~ 8%, pure calcium aluminate cement 3 ~ 5% and silicon powder 3 ~ 6%.Meanwhile, the invention also discloses the anti-preparation method for invading wear-resistant castable of above-mentioned high temperature.The present invention is compared with conventional art, and not only production technology is simpler, and cost is lower, kiln is not needed to fire, more energy efficient, abrasion diminishes, and anti-thermal shock is more preferable, because construction uses anchoring piece to add the integrated poured scheme of castable, refractory material good integrity, has prevented the shortcoming of similar refractory brick globality poor, lateritic nickel ore direct reduction process for rotary kiln high temperature section service life was up to more than 1 year and will not bring production accident because of disconnected brick etc., greatly reduce the production cost of ferronickel enterprise, the comprehensive power consumption of reduction.
Description
Technical field
The invention belongs to fire resisting material field, and in particular to a kind of high temperature is anti-to invade wear-resistant castable and preparation method.
Background technology
In recent years, as the improvement of people's living standards, stainless steel product is being increased with the demand more than 12% every year,
Also constantly developed rapidly as the ferronickel of the primary raw material product of production stainless steel, particularly lateritic nickel ore rotary kiln for directly reducing
Technology is developed rapidly.Because of little power consumption, the low advantage of more energy efficient, smelting cost, lot of domestic and international ferronickel enterprise progressively starts
Using the technique productions ferronickel, its operation principle is：Using lateritic nickel ore as raw material, using cheap coal, mud coal, middle coal as reducing agent,
Using rotary kiln as main production equipments, four steps are refined just by material the pre-heat treatment-reducing and smelting technique-water quenching-sorting
Product can be formed, with technique is simple, energy consumption is small, pollute less, cost is low, good product quality（Nickeliferous height, reaches 10-15%
Nickel）The advantages of.
Found in production process, the refractory material of lateritic nickel ore direct reduction process for rotary kiln high temperature section is now basic at present to be used
Based on magnesia fire-protecting wall, but there is disconnected brick, stripping in rotary kiln production process because itself compressive property is poor, often in magnesia fire-protecting wall
Fall, or even the serious problems such as collapse, cause the main cause of these problems：
1. rotary kiln is in production run, because rotary kiln diameter is big（2.8-5.6m）, length is long（Reach 60-110m）, therefore in life
During production operation, rotary kiln can produce huge torsion and radial shear power, because magnesia fire-protecting wall's compression strength is generally relatively low（Normal temperature
Compressive resistance ＜ 80Mpa）, so being particularly easy to disconnected brick and peeling occur, even collapsing.
2. high-temperature slag（1450-1500℃）Erosion and violent scour with metallic vapour to magnesia fire-protecting wall is especially tight
Weight, and reducing metal particle and a large amount of slags are produced after high temperature, because of magnesia fire-protecting wall, its wear resistance is relatively poor, so returning
Relatively easily worn and torn in rotary kiln production process.
3. because in production process, it sometimes appear that stopping kiln phenomenon, because magnesia fire-protecting wall's heat-resistant knocking stability is poor, typically existing
（1100 DEG C of water cooling ＜ 8 times）, therefore also it is particularly easy to disconnected brick.
Lateritic nickel ore direct reduction process for rotary kiln is most crucial, and the worst position of operating mode occurs in high temperature section, high temperature section
Inner lining refractory need to be subjected to calorifics, mechanics, the chemical depletion effect of most serious, therefore its high temperature section refractory material should possess well
The performance such as anti-erosion, high-wearing feature, high intensity, good thermal shock resistance.Magnesia-alumina brick, magnesia carbon brick, magnesium on existing market
Chrome brick, magnesium-aluminum-zirconium etc. are that, using magnesian as base material, therefore can not meet direct reduction of laterite nickel mine with rotary kiln technique, often
Property disconnected brick, fall brick, or even collapse（It is average to be monthly required for maintenance）.
The content of the invention
Goal of the invention：In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide, a kind of high temperature is anti-to invade wear-resistant pouring
Material.
Another object of the present invention is to provide above-mentioned high temperature the anti-preparation method for invading wear-resistant castable.
Technical scheme：In order to reach foregoing invention purpose, what the present invention was specifically performed by：A kind of high temperature is anti-to invade resistance to
Castable is ground, includes the component of following mass percent：Bauxite aggregate 50 ~ 70%, corundum aggregate 10 ~ 20%, white fused alumina fine powder 5
~ 15%, chromium oxide 3 ~ 8%, pure calcium aluminate cement 3 ~ 5% and silicon powder 3 ~ 6%.
Wherein, the fineness of the white fused alumina fine powder is not more than 100 mesh.
Wherein, the fineness of the silicon powder is not more than 20 mesh.
It is a kind of to prepare the anti-method for invading wear-resistant castable of high temperature, measure each raw material addition kneading machine by formula and kneaded,
Mixing carries out packaging of weighing after 30 ~ 40 minutes.
Beneficial effect：The present invention is compared with conventional art, and not only production technology is simpler, and cost is lower, it is not necessary to kiln
Fire, more energy efficient, abrasion diminishes, anti-thermal shock more preferably, adds the integrated poured scheme of castable, refractory material because constructing using anchoring piece
Good integrity, has prevented the shortcoming of similar refractory brick globality poor, makes in lateritic nickel ore direct reduction process for rotary kiln high temperature section
Up to more than 1 year and production accident will not be brought because of disconnected brick etc. with the life-span, greatly reduce the production cost of ferronickel enterprise, reduce comprehensive
Close power consumption.
