General Information

Refractory Acid-resistant brick is the main refractory materials of steel processing system cold-rolled sheet,
silicon steel line, etc. used for acid reproduction baking furnace, and its performance will directly
affect the service life and economic benefits of acid reproduction baking furnace.

It is used as working lining for anti erosion and acid proof pickling groove,acid storage tank,leaching tower,anti-erosion and acid proof floor,tubes and etc, Except hydrofluoric acid as the medium in chemical, petroleum, metallurgic, smelt, electric power, fertilizer, fiber, pharmacy, and alkaline system industries.

Applications
The reaction boilers, columns & tanks.
Mixing pools
Acid-resistant walls in non-ferrous metal industry
Acid-resistant structures in chemical industry.

Q:What role does silica play in refractories?
The production of clay brick refractory clay raw material is natural, its main mineral is kaolinite (formula Al2O3 - 2SiO2 - 2H2O), clay brick containing SiO2 in 45% ~ 65%, belongs to the weak acid refractory materials, have a certain ability to resist acid slag, but easy to be alkaline slag erosion.
Q:How to judge the quality of brick, clay brick, high alumina brick furnace from the appearance?
Mainly from the impurities to determine how much, generally less impurity single color brick.
Q:Common bond brick
Manufacturing for silica brick binder hi-li sulfate pulp waste liquid and lime milk. When lime milk is used as a bond, it acts as a plasticizer. To increase the strength of lime brick in the drying process, as mineralizer in the firing, promote the transformation of quartz.
Q:The brick is mainly used in the place?
Partitions used in coking and combustion chambers for coke ovens
Q:Common bond brick?
Lime should contain a lot of active CaO, I decompose CaCO3 and MgCO3 not more than 5%, Al2O3+Fe2O3+SiO2 no more than 5%. When the content of large particles, burned Ca-CO3 and over burned lime, the product produced caves, affecting the quality of products.
Q:Why is the new trend of the high thermal conductivity of silica brick
The use of high thermal conductivity of silica brick, reducing coke fuel consumption, reduce emissions of pollutants such as NOx, with considerable economic benefits and social benefits, is the future direction of the new technology of using coke oven refractory.
Q:The production of brick, the ingredients of why join the waste brick
Preparation of silica brick pug, a certain amount of waste silica brick used to add ingredients, for the purpose of expansion and stress reduction products when firing, reduce cracks, improve the rate of finished products.
Q:Why in the production of the brick to detect the volume density
Product quality control of silica brick.
Q:Can iron oxide be used as refractory material?
Iron oxide can not be used as refractory material, but it can be used as refractory additive. Iron oxide can be used as pigment
Q:The production of brick, the ingredients of why join the waste brick?
The production of silicon material is added to the cause of waste brick:Preparation of silica brick pug, a certain amount of waste silica brick used to add ingredients, for the purpose of expansion and stress reduction products during firing
