Introduction:

High strength high alumina castable is made of super high alumina clinker, composite binders and adhesives. The products are featured with high strength, good wear resistance, permeability resistance, erosion resistance, good mechanical properties, convenient construction, etc. It is commonly used in top of CFB boiler furnace, rear wall, etc.

Characters of refractory castable:

1. High refractoriness, high refractoriness under load.
2. High density, low porosity.
3. Good slag resistance and corrosion resistance.
4. High strength and wear resistance.

5. Good resistance to flake performance.

6. Good thermal shock stability.

7. Scouring resistance

8. Good hot strength.

Q: What is fireproof concrete?: Silicate fireproof heat-resistant concrete using temperature can reach 700 DEG ~800 DEG, the main mechanism of its heat is dehydrated calcium hydroxide silicate hydrates series of cement clinker under high temperature, the calcium oxide and slag and mixing activated silica material in the three and two aluminum oxide and the reaction of anhydrous calcium silicate and anhydrous aluminum acid calcium has strong heat resistance, the fire resistance of concrete is a certain. Such as the use of high alumina bauxite and broken bricks, magnesia brick and magnesia for fireproof heat-resistant concrete materials with the highest using temperature can reach 1100 DEG C.

Q: What is the difference between corundum and high alumina??: The main components of high alumina brick are high alumina bauxite, mullite and partial corundum sand.

Q: What's the difference between high alumina refractory bricks and high alumina refractory bricks?: High alumina refractory brick in all thermal shock properties except performance are better than clay refractory brick, masonry in furnace and thermal equipment, such as clay bricks can be competent the work environment is not high aluminum brick masonry.

Q: How many cubic bricks does a high alumina brick have?: It is related to the content of aluminum in high alumina bricks.

Q: What materials are used for roof insulation?: The other one is inorganic insulation materials, such as Portland, rare earth insulation, the thickness should be 5 cm or more, up to the high cost of auxiliary materials of construction, to reinforce, new inorganic insulation material, the material thickness, on the line of 2-3 cm, direct smear on the top of the house, without auxiliary material, than the price of wool, high aluminum silicate cotton.

Q: Which is faster for heat transfer between corundum bricks and high alumina bricks?: 75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.

Q: What are the alloy wear resistance materials?: According to the composition of Beijing Naimo metal materials company will wear resistant metal materials is divided into the following five categories: one: high manganese steel series: high manganese steel (ZGMn13),

Q: Use of high alumina refractory bricks?: High alumina refractory brick in Al2O3 more, close to neutral refractory material, can resist acid slag and alkaline slag erosion, because it contains SiO2, so alkaline slag ability than acid resistance slag ability less.It is widely used in building blast furnace, hot blast furnace, furnace top, blast furnace, reverberatory furnace and rotary kiln lining. In addition, high alumina bricks are widely used as furnace regenerative checker, pouring system for plug nozzle, etc..

Q: What are the lining structures of lime rotary kilns and what are the requirements for refractories?: The current configuration of domestic calcining active lime rotary kiln refractories are as follows: the discharge end of low cement high alumina castable with 3% steel fiber; the cooling zone and the firing zone: dry magnesia spinel brick with high aluminum brick with high temperature; preheating: high alumina brick; low temperature preheating zone: clay brick light clay brick; feeding end: low cement high alumina castable with 3% steel fiber; in addition, brick size also have the corresponding requirements; dimensional tolerances: dimensional tolerances used in different parts of the requirements are not the same, the general control in 2mm; corner damage: general permit edge damage 40mm and 5mm deep within angle loss in the hot and cold surface is allowed to have only one, three edges and the length of not more than 50mm; there are cracks parallel to the use of surface crack is not allowed, cracks of brick surface are allowed.

Q: High alumina brick 80 with which high aluminum cement?: In order to maintain a reasonable comprehensive lining, should adopt high quality aluminum refractory mud, such as Sichuan resistance card phosphate refractory mud, refractory clay, high alumina refractory mud PA-80 LN-75, if you use the card volume of Sichuan resistant refractory clay masonry, the effect is better.
