Q:Is refractory brick afraid of rain?
High alumina clay is not afraid of rain, but covering is better, magnesium carbon refractory brick had better not be rained.
Q:When using high alumina refractory brick, what are the reasons leading to the decline of the performance of high alumina brick?
The excess air coefficient is controlled in 1, in order to prevent producing water cracks in the production of high aluminum refractory brick from, control the water absorption of 2 grade clinker of bauxite with high alumina below 4%-5%. 1-1,the water absorption of the tube mill should also be controlled below 6%, and adjust thermotechnical, making the high alumina refractory brick burning be in the stable weak oxidizing atmosphere. should be 2
Q:is it good to use firebricks to preserve the heat of rto furnace? Is there any other good ideas?
1. what variety and grade of refractory materials should be chosen to build all parts of the industrial furnace?; 2. is the origin of these materials be assured? mesothern resistance furnace, lightweight refractory brick, refractory fiber, bead brick of 1000 degrees; fuel heating furnace, refractory clay brick, high alumina brick, silica brick, carborundum brick, refractory castable, the plastic refractory of 1300 degrees; heat treatment furnace, refractory clay brick, refractory fiber of 1100 degrees; high temperature salt bath furnace, refractory clay brick, high alumina brick, zircon brick, refractory castable of 1300 degrees; high temperature resistance furnace, lightweight refractory brick, high aluminum bricks, lightweight alumina brick, lightweight refractory clay brick of 1400 degrees; molybdenum wire furnace, alumina brick, corundum brick, carborundum brick, finished alumina hollow ball product of 1650 degrees; cupola, refractory clay brick, carborundum brick, dolomite Brick, carbon brick, graphite brick of 1650 degrees; arc furnac, high alumina brick, silica brick, magnesia brick, magnesia brick, magnesia chrome... Corundum brick, carbon brick, magnesia chrome brick, magnesia brick, high aluminum brick, silica brick, finished alumina hollow ball product of 1700 degrees; cupola, refractory clay brick of 1650 degrees;
Q:refractory bricks of fireclay
According to the preparation process, it can be divided into bricks, high alumina brick, magnesia brickand so on, such as refractory clay brick, and ordinary brick; according to the shape and size, it can be divided into standard brick and silica brick, it can withstand all kinds of physical and chemical changes and mechanical action at high temperature; silica brick can be used as high-temperature building materials and structural material to build kiln and kinds of thermal equipments. Refractory material and fused brick with a certain shape and size are called refractory brick for short.
Q:Whether yellow dextrin is used in refractory bricks?
use professional mortar, do not use yellow dextrin
Q:How many degrees of refractory brick if its surface turns red, how to test the temperature of refractory brick after it is burnt to red.
If the raw materials are different, then the redness is different under different temperatures.
Q:What mud is the refractory brick made of?
The main material of the ordinary refractory brick is clay, the main component is aluminium oxide.
Q:Lining of refractory bricks in rotary furnace
The lining of the converter is probably a furnace, but if it is changed at least to see the material and the use of it. There are a lot of damage to the lining, such as: The total impurity content reduces to 2%, lining life will increase 20%-40%; CAO in brick is of 60%-80% content , lining life are the highest; also some other proper index can not be ignored such as bulk density,heat/thermal shock resistant performance,porosity,thermal expansion,fracture resistace,volume stability,Slag resistance,and so on. In addition, lining erosion rate is the largest when the basicity of slag is 1, with the increase of basicity, erosion rate decrease rapidly, the temperature can cause cracks spalling of lining. At the same time, the building process is also very important.
Q:How much fireclay is needed per cube refractory bricks?
Normal refractory bricks need to use 70-80kg refractory mud each cubic . In fact, this can be calculated, because the volume of refractory bricks and refractory mud density can be measured. Of course, here is an important point, that is the size of the brick seam, 1mm brick seam and 3mm is significantly different. Sichuan brand refractory mud has many kinds, like high aluminum, clay, corundum, magnesia, insulation and so on, the dosage is different.
Q:What is the raw material for the production of refractory bricks?
Mainly Magnesium Oxide, use sodium silicate as a binder.
