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:The difference between light high alumina brick and heavy aluminum brick
Lightweight high alumina bricks, commonly called insulating refractory bricks, also known as insulating refractory bricks. First of all, literally, lightweight aluminum bricks and heavy aluminum bricks are very different in weight. Lightweight high alumina bricks, also called insulated high alumina bricks, are designed for insulation and heat preservation. In normal use, the utility model is not directly contacted with the furnace temperature, and is a refractory brick product which is close to the furnace wall and has the function of heat insulation and heat preservation.
Q:Can high alumina brick resist carburizing?
Louzhu can use heavy impervious material, it is neither high alumina brick nor mullite, this product can resist seepage and have good compressive strength
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?
Generally, the thermal shock resistance of high alumina brick products is worse than that of clay brick products
Q:What is the heat preservation material used in a laboratory furnace?
Silicon carbide (SiC) is made from quartz sand, petroleum coke (or coal tar), sawdust (green salt produced when adding green silicon carbide) and other raw materials by smelting with resistance furnace at high temperature. Silicon carbide also rare minerals in nature, Mo sangshi. Silicon carbide, also known as carbon silica. Silicon carbide is the most widely used and the most economical kind of refractory materials in C, N, B and other non oxide refractory materials. It can be called "carborundum sand" or "refractory sand".
Q:What's the price of high alumina refractory bricks?
The price of high alumina refractory bricks varies greatly according to the content of AL2O3.
Q:What are the requirements for Rubble backfill height?
1, filling thickness is not greater than 50cm.2, filling, the use of layered filling.
Q:What is the difference between corundum and high alumina??
The main components of high alumina brick are high alumina bauxite, mullite and partial corundum sand.
