Vice White Fused Alumina

Vice White Fused Alumina is developed on the basis of brown fused alumina smelting. The Vice White Fused Alumina can substitute compact Fused Alumina to make tapping launder castable refractory.

Vice White Fused Alumina can also substitute white fused alumina and tabular Alumina to make sliding plate, corundum bricks and abrasion-resistant castable etc. All of which have achieved the same effectiveness compare with usingcompact fused alumina and white fused alumina.



Vice White Fused Alumina has the hardness of White Fused Alumina, and it also has the toughness of brown corundum. It is used to replace the iron grate castable made from dense corundum, as well as the skateboards, corundum bricks, wear-resistant castables, etc. that are made by replacing white corundum and plate corundum. Acquire and use dense corundum, white corundum and other equivalent effects.

The Vice White Fused Alumina Segment sand, and Vice White Fused Alumina Powder have the characteristics of no bursting, no chalking, large stacking, and good fluidity during use, and can be widely used to produce a variety of shaped refractory products and corundum casting materials and other amorphous bulk materials and light fired corundum refractory products.

Ceramic Roller Kilns - The best Ceramic Roller Kiln from Luwei Ceramic Roller Furnace.

Description of Ceramic Roller Kilns
Ceramic Roller Kilns for fast firing of wall and floor tiles have been used for nearly 25 years. In this type of kiln the products to be fired are transported through the kiln by means of rotating ceramic rollers. Ceramic Roller Kilns is manufactured using optimum grade raw material and sophisticated technology in synchronization with international standards. In order to ensure quality, the entire range is rigorously tested on various parameters by our quality controllers.



The Ceramic Roller Kilns offers the manufacturer a fuel efficient solution where cycles are fast and products require a very tight temperature uniformity. For special technical applications, Nutec Bickley have provided roller hearth kilns as an alternative to shuttle or tunnel kilns. Ceramics rollers are supplied in different materials (mullite or silicon carbide) depending on the application requirements.

Features of Ceramic Roller Kilns
The Ceramic Roller Kilns is mainly used in the production of ceramic tiles table dishware bone teaset pottery bowls ceramic gifts and other ceramic building materials. Ceramic Roller Kiln is continuous heating and work it is made by the rotation of the ceramic tube as the roller kiln vehicle the ceramic tiles or bricks materials in the kiln inner chamber. The rotation of the ceramic tube with high temperature(high-alumina)or SiC depending on the calcination temperature and ar driven by independent controller.

Brown Fused Alumina Micro Powder

Brown Fused Alumina is made of high-quality bauxite as the main raw material, and it is made into various particle size products by adopting processing methods such as purification, impurity removal, crystallization, sorting, crushing, magnetic separation, and sieving in the high temperature above 2200°C of the arc smelting furnace.

Brown Fused Alumina Powder is made of natural bauxite as raw material, carbon (mainly coke) as reducing agent, and iron scrap is added as settling agent (clarifier) ​​to form ferrosilicon at the bottom of electric furnace.



Brown Fused Alumina Micro Powder is tan, generally Al2O3 ≥ 94.5%, SiO2 ≤ 3.5%, TiO2 ≤ 3.5%, Fe2O3 ≤ 1%. The mineral composition is dominated by α-Al2O3. The central part of the crystal shape is diamond-shaped, thick plate-shaped, and cracked particles. There are more silicon oxide and calcium oxide in the periphery and melt crystallize, showing a long plate shape and the most coarse grains. Slit platelets.

Since the impurities have not been completely removed, the brown fused alumina also contains secondary phases such as calcium hexaaluminate, calcium plagioclase, spinel, rutile, and glass phases, ferroalloys, and solid solutions. The color of Brown Fused Alumina depends to a large extent on the titanium oxide remaining in the product.

Brown Fused Alumina Micro Powder performance include High hardness, high strength, impact resistance, high temperature resistance, oxidation resistance, corrosion resistance, low creep, etc.

Brown Fused Alumina is mainly used as abrasive. In recent years, it has been used as the raw material for large and medium-sized blast furnace cast iron hook castables and cast iron aggregates and for the production of common corundum bricks (including high-alumina silicon carbide casts).

Brown Fused Alumina Micro Powder is suitable for making bonded and coated abrasive tools, wet or dry blasting, superprecision grinding and polishing, making high quality refractory materials, grinding carbon steel, alloy steel, malleable cast iron, hard bronze and semi-conductor materials.

The role of Fused Cast AZS Bricks in Glass Furnaces

For a glass kiln, Fused Cast AZS Bricks effect in galss furnace is very important, in order to achieve the design life or to avoid contamination of the glass solution, a thorough understanding of the appearance quality and intrinsic quality of the fused cast bricks is required. we need to understand the performance of the fused cast azs bricks and the weak points of the fused cast bricks.



First, the appearance quality of Fused Cast AZS Bricks in Glass Furnaces, the pool wall part of the corner brick, kiln chopped brick, bubbling bricks, liquid flow brick is generally fused cast azs 41#. With the neighboring brick assembly gap to be strict requirements, the gap assembly to speed up the glass solution on the brick erosion, assembly The gap requirement is not more than 0.5mm. It is advisable that there is no shrinkage hole at the bottom of the brick. More than twelve per cubic meter of surface air holes above the ¢2mm are not allowed. The color of the brick body is yellowish and white, bubbling, and liquid flow bricks are not allowed. The presence of cracks does not allow the presence of flaws within 300 mm of the top of the pool wall section.

Second, the intrinsic quality of Fused Cast AZS Bricks in Glass Furnaces.
1. From the brick color to determine the impurities in the fused cast brick, or to determine whether the carbon content is large, the color of the large carbon brick will be green, this brick is strictly prohibited.
2. While a massive greening on the surface of the brick body, there must be iron blocks inside. The iron blocks come from the flat material in the production process or the iron and solder part of the exhaust gas falls off, and other factors. This imagined brick is also prohibited.
3. The glass phase contrast must be strictly controlled. When the glass phase exceeds the standard, the large amount of glass phase precipitated at high temperatures can reduce the service life of the furnace and contaminate the glass melt.

Pusher Kilns - The best Pusher kiln from Luwei Ceramic Pusher kilns.

Description of Pusher Kilns
Pusher Kilns and tunnel kilns are ideal for processes requiring precise control of temperature and atmosphere, for those with longer residence times that require exact control of the heat up rate of the product (temperature profile), and those with a lower gas/solid reaction.



The Pusher Kiln has a hydraulic system that pushes load trays (ceramic or metal) through the kiln tunnel. The trays may push through various zones of temperature to meet a particular temperature profile. For larger load sizes, more than one tray may be pushed in at a time. When the trays reach the exit end of the kiln, they may be manually or automatically returned to the entrance end for reloading. As in the Car Kiln, the entire process can be automated to be safer and more efficient.

Features of Pusher Kilns
Pusher Kilns is mainly used in the production of ceramic tiles table dishware bone teaset pottery bowls ceramic gifts and other ceramic building materials. Pusher Kiln is continuous heating and work it is made by the rotation of the ceramic tube as the roller kiln vehicle the ceramic tiles or bricks materials in the kiln inner chamber.
