Q:What are the application of used refractory brick pieces?
auxiliary material made of refractory bricks or refractory is not as good as that of bauxite.
Q:What are the materials for building blocks and what are the specifications?
Material: clay brick, shale, coal gangue brick, fly ash brick, lime sand brick, concrete brick etc..
Q:Do refractory bricks resist corrosion and sulfur?
The refractory brick just plays the role of resisting high temperature and insulating heat.
Q:Which is the higher price of concrete solid brick and MU15 fired common brick (non clay brick)?
On the wall to change the gradual implementation of the policy process, as excessive wall material, porous clay brick wall reform in some areas has completed his mission to history, new material shale and shale gangue to replace clay brick emerging. In order to promote the application of porous brick technology (Kong Xin), to further implement the policy of building energy saving and wall reform work, put forward the national standard design atlas "porous brick wall building structure" 96SJ101 "and" 96SG612 structure of porous brick wall revision work of the 2003 China building standard design and research institute.
Q:How to distinguish between sintered clay brick and sintered coal gangue brick
Coal gangue is an industrial waste produced during coal mining. Using coal gangue as raw material for the production of new wall materials, both to protect the ecological environment, but also save the land, save energy, it meets the development policy of wall materials industry in China, is a new wall material attaches great importance to and vigorously support the development of the.
Q:What raw materials can be added to fireclay brick to respond to the urgent cold and urgent heat?
The effect of adding andalusite is better
Q:Is the diameter of 2.5 meters of the calcium aluminate powder rotary kiln referred to the inner diameter of the refractory brick?
No, it should be outer diameter.
Q:Which thermal stability of clay bricks and high alumina bricks is good?
Thermal shock stability is much better than clay brick.
Q:What are the differences between sintered bricks and refractory bricks?
Sintered bricks belong to a type of refractory bricks.
Q:buliding method of refractory bricks in boilers
