High Purity Acid Resistant Alumina Ceramic Lining Brick

Refractory brick made of sillimanite minerals.Sillimanite into after high temperature calcination mullite and free silica.Commonly used high

temperature burning method and mud casting method.The physical and chemical performance is better than high alumina brick, 1770 ~ 1830 ℃,

refractoriness under load softening the starting point of 1500 ~ 1650 ℃.It is mainly used for glass tank furnace discharge hole forming,

blast furnace lining, furnace throat and ceramic industry kiln furniture.

Crystalline silicon steel gray, amorphous silicon is black, 2.4 g/cm3 density, melting point 1414 ℃, boiling point 2355 ℃, crystalline silicon atomic

crystal, hard and glossy, semiconductor properties.Silicon structure are similar to diamond, is a regular tetrahedron structure.Silicon chemistry

more lively, can at high temperature and oxygen etc. Various elements combined, insoluble in water, hydrochloric acid and nitric acid, soluble in

hydrofluoric acid and alkali, used to build alloy such as ferrosilicon, silicon steel, silicon single crystal is a kind of important semiconductor materials,

used in the manufacture of high power transistor, rectifier, solar cells, etc.Silicon is widespread in nature, containing about 27.6% of the earth's crust,

mainly exists in the form of silica and silicates.In the crust, the content of silicon in all elements content is second only to oxygen, second.Its shape is divided into crystalline form and network form

Q:Is it good for your cupola to use that kind of refractory, high aluminum brick, clay brick or red silica?: The high aluminum clay brick is slightly more stable and can be used!

Q:I am a student of refractory materials. I would like to know the general rank of national refractory materials company: Zhejiang Sunon Refractories Co., Ltd. is a group member of the factory of industrial economy research China (country), building materials building materials industry center Changxin Branch Center of refractories. The main products are: wear-resistant refractory brick, aluminum silicate fiber board, ordinary magnesia, heavy casting materials, spalling brick kilns, special casting materials, high strength and abrasion resistant castable refractory castable, special pulverized coal burner, MF-170 coating (with fabric), clay brick, corundum wear-resistant plastic, calcium silicate board, lightweight castable and the direct combination of magnesia chrome brick, unburned magnesia chrome brick, anti flaking high alumina brick, mullite brick, antiskinning castable,

Q:What refractory materials are adopted in each part of the blast furnace?: Bosh temperature reaches 1600~1650, high alumina brick, corundum brick or silicon carbide brick. The upper hearth tuyere zone near the temperature at 1700~2000 Deg. C, the use of sillimanite brick, corundum and silicon carbide refractory filler, Shi Mozhi. Bottom temperature at 1450~1500 Deg. C, the use of graphite bricks and microporous carbon brick, now also used corundum brick, Gang Yumo brick and synthetic mullite brick.

Q:Sillimanite brick: After calcination at high temperature, sillimanite transforms to mullite and free silica. Generally use the firing process and production of high temperature mud casting method. Its physical and chemical properties are better than those of aluminum bricks, the refractoriness is 1770~1830 degrees, and the load softening point is 1500~1650 degrees centigrade. The utility model is mainly used for the forming of a liquid hole in a glass furnace, a lining of a blast furnace, a furnace throat and a ceramic industrial kiln tool.

Q:What kind of refractory material will be used in the glass kiln?: 3. standard zirconium brickThe content of ZrO2 in the brick is about 66%, and the bulk density is 3.7g/cm3, which has better thermal stability and anti stripping property. The use of erosion serious investment outlet area and after the parapet wall in the powder melting furnace, observation hole brick and pathway of flame space and roof parapet wall brick, brick burner. But there are also AZS burner brick with mullite brick for brick kiln and transition two side clearance brick etc..
