Q:What are the high aluminum bricks made of?
The amount of refractory mud accounts for about 6% of the brick weight
Q:How much is the bending temperature aluminum silicon carbide brick for torpedo car
The product has the advantages of high temperature, little creep, strong corrosion resistance and good thermal shock resistance, and is suitable for large and medium-sized hot blast stoves.
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 is the price of the latest thermal insulation material?
Also through online pre understand the products and prices, and now have large-scale manufacturers are generally opened on the cable business. Goods than three, manufacturers on-site inspection, confirm the quality of goods after considering cooperation.
Q:What is the density of a super high alumina brick and what is the price?
Of course, the transaction price, please choose refractory brick manufacturer is better.
Q:How to reduce porosity of high alumina brick
In order to reduce the porosity of high alumina brick, the corresponding measures should be taken from the selection of raw materials, batching, mixing, molding and firing.The water absorption rate of the first grade high alumina bauxite clinker should be less than 5%, and the water absorption rate of two grade high alumina material should be less than 7%. Fine grinding of soft clay and bauxite clinker with less than 4% water content. Mixed fine milling ingredients with this, can reduce the porosity of bricks.
Q:What is the standard classification of high alumina bricks or high alumina bricks?
High alumina brick is a kind of refractory material in refractory brick products. It is made of refractory clay or other refractory material. It belongs to the product of Si Al System
Q:How to distinguish the good or bad of the high aluminum brick?
In the procurement of high alumina brick, the first color, high quality aluminum brick, brick surface smooth, yellow color pale, four sides equal, no broken angle, no cracks.
Q:Density of high alumina bricks
Alumina content of 48% or more, mainly from mullite and glass phase or corundum composition of lightweight refractory. The volume density is 0.4 ~ 1.35g/cm3. The porosity is 66% ~ 73%, and the compressive strength is 1 ~ 8MPa. Better thermal shock resistance.
Q:What are the high temperature refractory mortars made of?
Siliceous mud, mineral composition and chemical composition is similar with silica, excellent corrosion resistance, water glass slurry, drying shrinkage, but also can be used for bonding fiber products, sealing furnace wall.
