Q:How to adjust the temperature in the 160 meter tunnel kiln?

Tunnel kiln can be attemperated by burning products, this will not affect the firing of different products, and can burn back processing products.

Q:does furnace use refractory cement to make refractory bricks?

consistence Mainly concern about the strength, generally masonry mortar does not consider the degree of fire resistance

Q:What are the hazards of solid clay bricks?

The prohibition or restriction of high energy solid clay brick production, the development of low energy consumption, thermal insulation of new wall materials, insulation performance is good, not only can save energy in production, but also can make the function of the building can be effectively improved, reducing the energy consumption in buildings in use.

Q:What is the density of the high alumina refractory brick?

it depends on the aluminum content, the higher it contains, the larger the density is. the hjghest is 3, the lowest is 2.

Q:Why can't gravity retaining walls be made of clay bricks?

The masonry of gravity retaining walls, of course, takes into account compression problems, and the use of clay bricks requires consideration of compression calculations and service life.

Q:Is there any special requirements for the building blocks of the smoke and gas wells, how about the refractory bricks?

There are no special requirements. Not necessarily need refractory bricks, red bricks are ok. The building size of the flue is according to the smoke exhaust rate.

Q:Are buildings allowed to use red bricks?

Clay brick is forbidden to be used by the state, whether red or green. Red and cyan are just the difference between making techniques. Now also produces appearance and clay sintering, red brick like silicate sintered brick can be used.

Q:What to do if refractory bricks saltpeter when they are used outdoor

Efflorescence is usually dialysised from brickwork joints, dealing with the gap is ok These white substaince inside the pan tile: Cement efflorescence efflorescence is wow cake section from light leather intestinal common disease inumiya Hua building surface, according to their different causes and manifestations, there is pan cream, white, whitening, cream, on the walls and decorative surface erosion and other names, is the change of soluble saline alkali soil, adobe, brick, cement, mortar, concrete, masonry, ceramic tile, paint and other building materials with temperature, humidity and other external environment, in a water absorption, water transfer, water evaporation process with physical and chemical changes of the original building material damage disease phenomenon, erosion degree also has the very big difference there is a common, get damp, foaming, powder, drum, hollowing, cracking, spalling, mildew and crystallization phenomenon. Cement efflorescence may have some relationship with the quality of the cement, sand, water, air, temperature, humidity, it is a common fault in building. Use cement to do the pebble shape, it also prones to the above problems: A layer of white stuff on the surface. Terms of settlement： Scrape the dust in brickwork joint, pointing again. Use special pointing agents, more resistant to corrosion, not easy to efflorescence.

Q:What material is good of refractory bricks?

It can also be divided into a variety of kinds, it mainly depends on where it is used, each has its own advantages, neutral three categories of refractory bricks have a variety of materials

Q:T38 size of high alumina refractory brick

high alumina brick, according to the aluminum content, is divided into four grades, the aluminum content of the first grade is no less than 75%, also called the special high alumina brick; the aluminum content of the second grade is no less than 65%, the third grade is no less than 55%; the aluminum content of super high aluminium brick is more than 85%; If the shape is very irregular, it is usually called the super special high alumina brick. in short, there is a universal type of high alumina brick except for standard high alumina brick, customised according to the specific appliction of the kiln.
