- Q: What are the weak points of clay bricks?
- SiO2 and Al2O3 in clay bricks form eutectic, low melting point silicates with impurities during sintering, and are surrounded by mullite crystals. Clay brick belongs to weak acid refractory products, it can resist acid slag and acid gas corrosion, and its resistance to alkaline material is a little worse. The thermal performance of clay brick is good, it is fast and cold. The clay brick refractory brick and be roughly the same, up to 1690~1730 DEG C, but the load softening temperature is 200 degrees Celsius above the low brick. Because clay bricks contain crystalline Mullite with high refractoriness, they contain nearly half of the amorphous glass phase of low melting point.
- Q: Is the quality of refractory brick influenced if it is soaked by water
- Refractory bricks shouldn't be got wet by damp. Other refractory brick is not much problem, after touching, please wash hand, or masonry stove ignition will burst. In addition, refractory bricks containing chromium can't meet water, it's easy to hydrate and scrap, it will generate Cr VI ( chromium VI ), which is hanrmful to health and pollutes the environment, but try not to get wet
- Q: Why should the clay bricks be watered first when they are building masonry walls?
- And because a portion of the water in the mortar brick absorb, can lead to early dehydration, but are not very good on the hydration of the brick and mortar bond strength weakened, greatly reduce mortar and masonry compressive strength, shear strength, affecting the integrity and seismic performance of masonry.
- Q: Mainly use the raw materials inside refractory bricks,
- Go to the refractory factory to buy some refractory mortar that has the same texture of refractory bricks, the general boiler use clay refractory mortar.
- Q: several refractory brick of rotary kiln several is damaged, how many refractory bricks should be replaced?
- The life of refractory bricks in rotary kiln is generally short.
- Q: What are the simple ways to distinguish between excessive clay bricks and less fired clay bricks?
- Refers to the internal combustion brick to save raw material and fuel in clay mixed with waste parts containing combustibles, such as coal cinder, coal gangue and fly ash, and make the fuel burning in a brick in the baking process, so as to obtain uniform calcination temperature and combustion, called by this method of roasting brick brick.
- Q: When the coal-fired steam boiler is built, it is necessary to build a common red brick between the refractory bricks. May I ask what is the requirement for this common red brick?
- It has requirement for the external dimension (but not as strict as the requirement for the refractory brick), or it can not meet the thermal insulation effect and affect the appearance, and the appearance of the furnace wall is not beautiful
- Q: What can be applied to the burned refractory brick to resist heat shock?
- Acidic refractory material use monox as the main component, among which cilica brick and clay brick are commonly used. Silica brick is silicious product containing monox more than 93%, whose raw materials include silica, waste silica brick scrap and etc. The acid resistance of slag erosion ability is good, and the softening temperature under a fixed load is high. The volume won't shrink after repeated burning, but even a slight expand; but it is vulnerable to the erosion of basic slag, and has low thermal shock resistance. The silica brick is mainly used for coke oven, glass melting furnace, acid hearth furnace and other thermal equipments. Clay brick uses refractory clay as the main raw material, containing 30% to 46% of aluminuum oxide, belong to weakly acidic refractories. It has good heat shock resistance and corrosion stability to acid slag, and it's widely used. Neutral refractory materials use aluminum oxides, chromium hemitrioxides or carbons as the main components. Corundum products containing more than 95% of alumina is a kind of high quality refractory material with wide application.
- Q: What kind of refractory material is used in the furnace when the boiler reaches more than 1200 degrees?
- except refractory brick, refractories include refractory concrete (refractory cement+aggregate), fire-resistant insulating layer (refractory cement+vermiculite powder or refractory cement + diatomaceous earth) and so on.
- Q: How to make refractory bricks? ? ?
- Solution of the production of refractory brick raw materials
