Q:Does circulating fluidized bed boiler's furnace wall use refractory to have thermal insulation?
Now all use castable refractory, the outer layer is generally pouring refractory castable, the inside layer is a heat insulation castable refractory.
Q:Where the refractory bricks rider bricks that are used for building arch and vault should be put?
Arch and vault shall be built simultaneously from both sides of the arch of the foot to the center of symmetry, when masonry, inverting concentric reducer of arch brick is prohibited; the lock should be driven into the brick arch from the side, if the last rider brick can't be driven from the side, you can process the first 1-2 brick to make the size of the lock and the lock buckle equal, and then drive suitable rider brick from top, and use steel plate to jam-pack the side; dismantling arch tire must be performed after all rider bricks are driven and lock brick arch foot ditch masonry is completed and the final tightening nut for skeleton retractor rear.
Q:air-cooled razheng times of magnesia-alumina spinel refractory bricks
The ingredients are magnesium, oxygen, and aluminum. the components of spinel refractory can be magnesia-alumina spinel with excessive aluminium oxide, or magnesia-alumina spinel with excessive magnesium oxide. excessive magnesium oxide and aluminium oxide can form magnesia-alumina spinel in above 1700 degrees.
Q:What is the meaning of the new type of dry rotary kiln refractory brick 620,320?
It should be the length of the turn. I'm not sure if it is right.
Q:How about clay bricks?
Fired ordinary brick is one of the indispensable building materials in production and life, but its quality is not good or bad in the absence of professional equipment. Now to introduce a little trick:According to the main raw materials for clay brick, shale, coal gangue and fly ash brick. Mainly in our local clay brick. According to the compressive strength of weathering resistance of radioactive material and qualified brick, according to the size deviation, appearance quality, efflorescence and lime burst into superior products, first-class products, qualified three quality grades.
Q:Why is the house made of refractory bricks not warm in winter
Refractory bricks are not used in the house, but used in a large boiler inner
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:Are refractory bricks poisonous?
Zirconium minerals are often associated with other minerals in the mining, because the bricks are basically burned under more than 1 thousand degree. But some of the bricks contain heavy metal elements chromium. Some of the brick contains zirconium, the vast majority are very safe, and heavy metal elements have a certain toxicity, there are many kinds of refractory bricks that the nature is very stable, and the associated minerals are generally radioactive
Q:Which is better for tunnel kiln suspended ceiling, refractory brick or ceramic fiber module ?
If there is no strong hot erosion by airflow, then module is certainly better
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.
