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:How to reduce porosity of high alumina brick
High alumina brick used as refractory products in refractory material, has a great application in masonry kilns, insiders pointed out that the quality of high alumina brick general porosity and it has a great relationship! So, how to reduce the porosity of high alumina brick rate is very important!
Q:What are the common thermal insulation materials for thermal conductivity?
Aerogels are known to be the lightest solid materials in the world. It is made of nanometer silica aerogel as main material and is compounded by special process. The utility model has the advantages of high temperature resistance, low thermal conductivity, small density, high strength, green environment protection, waterproof and non inflammable performance. At the same time, with excellent sound insulation and shock absorption performance, it is now widely used in metallurgy, chemical, national defense, aerospace and other fields, is an indispensable high-performance insulation materials.
Q:In 2016, a few of the traditional refractory materials will be able to survive
In short, the overall market of refractory enterprises is in a turbulent adjustment process, but the volume is still in place. Elimination is inevitable, as to how many can be eliminated, dare not assert.
Q:How to reduce the harm caused by two times mullite in high alumina refractory material
Prolong the sintering time and adjust the aluminum content of the high alumina brick.
Q:Application characteristics of high alumina brick
Refractoriness. High alumina brick products are advanced varieties of aluminium silicate refractory products, and their refractoriness increases with the increase of Al2O3 content, generally not less than 1750 - 1790 DEG C. If the content of Al2O3 is more than 95% of corundum brick, the refractoriness can be as high as 1900-2000 degrees.
Q:Which thermal shock stability of clay brick and high alumina brick is good?
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.Thermal shock stability is much better than clay brick.
Q:How to distinguish the good or bad of the high aluminum brick?
Weigh the weight of the next block. According to the weight standard, a high alumina brick is 3.9 kg in weight, two in high alumina brick, three in high aluminium brick and 4.5 kg in 4.2. The same grade, the same type of high alumina brick, if the weight of a single brick to this standard, but for high quality high alumina brick, otherwise, can not reach such a weight, it shows good quality. If there is a crack, a large piece of broken angle, four sides of inequality, it is for substandard products.
Q:What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?
Quality requirements for aluminium bricks of different grade. 2, high aluminum powder and high alumina aggregate and other materials of reasonable proportion, to reach the production requirements.
Q:What is the difference between T3 refractory bricks or high alumina refractory bricks?
The T3 in T3 refractory bricks refers to the model indicating that the refractory brick model is T-3, and that the corresponding T-3 model is 230*114*65 (mm)
