- Q:Is the waste of the fire resistant hazardous waste?
- Can be recycled and reused.
- Q:several refractory brick of rotary kiln several is damaged, how many refractory bricks should be replaced?
- In general, if the brick inside the kiln break or loose core, the bricks of whole circle should be replaced, if only mend by replacing a damage part is also ok, but the service life is shorter.
- Q:What are the ingredients of brick?
- Is the most traditional brick masonry material, its composition is clay as the main raw material gradually to the development of industrial waste utilization of coal gangue and fly ash, and by solid and hollow porous to development, development by sintering to non sintering.
- Q:The harm of wet bricks used in refractory bricks
- Increase the natural protection time, increase the baking time, or water can not discharge, this will cause swelling deformation of furnace wall.
- Q:Are clay bricks radioactive?
- Basically, any substance has radiation, because natural conditions contain a lot of radioactive particles, and even the body itself has reflective particles, such as carbon 14, but the dose is safe.
- Q:How to prevent the refractory bricks from burning to crack?
- There is just allowed a little moisture contained in adobe.
- Q:Why is there cracks in the use of refractory bricks?
- Several reasons for the emergence of cracks: (1) temperature difference stress (2) mechanical stress (3) crystal type change stress
- Q:What are the type, location and the physical and chemical effects of the refractory brick used in the cement rotary kiln?
- But most people use high alumina brick or clay brick, G6 refractory brick. The specific masonry location, such as G4 refractory brick, standard brick, T38, OD, T39, according to the length of your rotary kiln, many kinds of refractory bricks are used in cement rotary kiln, the specific size of the inner diameter should be calculated in detail
- Q:What is the difference between the refractory bricks, hand-made bricks and the machine pressure bricks?
- The density of hand-made is not enough, it's light, while the density of machine pressure is high, it's heavy, each has their own benefits
