Specifications

  1. Low creep under high tempereature
    2.High refractoriness under the load
    3.Less pollution
    4.ISO 9001


  2. Function:


    Dolomite is a carbonate mineral comprised of magnesium and calcium. Dolomite isn't a fertilizer, but a soil conditioner that's used to "sweeten" acidic soils and make them more alkaline. Because dolomite is particularly slow-acting, it must be added to the soil well in advance of planting to gain the desired benefit. Powdered dolomite lime can also be mixed into a nutrient rich fertilizer blend so that you can enrich the soil and correct its pH at the same time..

Q:What is the difference between fireclay bricks and high alumina refractory bricks?
First of all, there is a difference in the material, one is clay, and one is high aluminum.Also known as clay brick brick, is a man-made small bulk building, clay brick clay (including shale, coal gangue powder) as the main raw material, through mud processing, molding, drying and roasting, solid and hollow.
Q:What are the grades of high alumina bricks?
According to the size of high aluminum brick is divided into: standard brick, special-shaped brick.
Q:What does refractory consist of
According to the chemical characteristics of refractory raw materials can be divided into acidic refractory materials, such as silica, zircon etc.; neutral refractory raw material, such as corundum, bauxite, mullite (acidic) (acidic), Ge (alkaline) iron and graphite; alkaline refractory materials, such as magnesite, dolomite, magnesium sand calcium sand.
Q:What refractory material does cupola lining use?
Materials defined as physical and chemical properties that allow them to be used in a high temperature environment are called refractory materials. Refractory materials are widely used in metallurgy, chemical, petroleum, machinery manufacturing, silicate, power and other industrial fields, the largest amount of metallurgical industry, accounting for 50% ~ 60% of the total output.
Q:What is the price of the first grade high alumina brick?
Many factories in Xinmi have high alumina bricks, but they must choose a regular factory. Kuwait refractory level high aluminum brick price at around 1600, the quality of double stable supply
Q:Density of high alumina bricks
The density of high alumina bricks is determined according to the price. The average density is between 2.3-2.5g/cm3. The higher the density, the higher the price, the higher the aluminum bricks are in the industry. More than 2.4 are required.
Q:The difference between ordinary and diatomite brick refractory brick
To say the difference, the material is the biggest difference. There are diatomite brick density, compressive strength of small brick kiln belongs to the outer thermal insulation, and heavy refractory brick kilns for multi village in direct contact with the flame, high temperature resistance, good compressive strength, but no insulation. Hope to help you.
Q:What are the common thermal insulation materials for thermal conductivity?
The vacuum heat insulation plate is a kind of high efficiency thermal insulation board made of inorganic fiber core material and high resistance gas composite film. It is made of vacuum encapsulation technology and covered with special interface mortar.
Q:Corundum, high alumina and fireclay refractory difference is what
Corundum is unknown. The high alumina brick has higher aluminum content than the clay brick, and the temperature resistance is higher than 300 degrees. It is more durable and durable than the clay brick. The production process of high alumina brick is better than that of clay brick. For example, the weight of good clay brick is 3.7kg, and that of high alumina is 4.2kg. Good density. But the price of high aluminum is too high: ordinary clay brick (standard brick example) in 1.1--2.5 yuan / block, high aluminum to 4.5 yuan / block, or even more expensive. The extra high aluminum has reached 5000 tons. Say straight white point is: under the same conditions, clay brick for a period of one year, then the high aluminum for more than three years.
Q:What's the weight of the refractory bricks?
Fireclay refractory bricks: 3.4kg-3.8kg - according to the quality of raw materials, prices ranging from 1 yuan to 2.7 yuan, high alumina refractory brick: three, high aluminum in 3.9kg or so. Ordinary T-3 firebrick weight calculation method: 230*114*65*2.2/2.1.
