Q:Ask for help about the phase of refractory material
Major crystalline phase. The main crystalline phase is a crystalline phase that constitutes the principal part of the material structure and has a high melting point and a dominant role in the properties of the material. The properties, quantities, distribution and bonding state of the main crystalline phases of refractory determine the properties of the products directly. A lot of refractory products, such as mullite brick, corundum brick, magnesia brick, magnesia spinel brick, silicon carbide refractory products, etc., are the main phase named.
Q:What problems should we pay attention to in the use of fused zirconia corundum brick (fused zirconia corundum brick) in glass furnace?
Casting, casting mouth often appear shrinkage, brick porosity more, the density is lower, so in the brick wall of glass melting, the shrinkage in the kiln direction, if the nozzle outward, when the brick to erosion is very thin, can cause leakage of liquid glass accident. When the flame space is used in the upper part of the bath furnace, the service life is long, and the glass liquid problem can not happen, so the casting mouth is used outwards, and the service life is prolonged.
Q:What is the hardness of corundum refractory bricks?
Such as zirconium corundum refractory brick, chrome corundum refractory titanium corundum refractory brick.
Q:What are the main constituents of refractory bricks
Refractory brick composition is mainly composed of a variety of aggregate or aggregate and one or more kinds of sticky agent composed of mixed powder particles, when used, must be mixed with one or more liquids, mixing evenly, with strong liquidity. Different refractory bricks are different, such as silicon, aluminum, clay and so on:According to the composition of refractory bricks, they can be divided into five major categories, namely, silicon aluminum refractory bricks, basic series refractory bricks, carbon containing refractory bricks, zirconium containing refractory bricks and insulating refractory bricks. Any furnace is not made of only one kind of refractory brick, and it needs different fire bricks to match with each other. The following five categories of refractory bricks are described in detail.
Q:What kind of refractory material will be used in the glass kiln
High temperature & glass corrosion performance of the brick is slightly lower than that of chromium oxide, also by isostatic pressing forming method, its technical indicators ZrO2>65%, <2.0% porosity, volume density of about 4.25g/cm3, the temperature in E glass is higher than 1370 DEG C have erosion. Used in the E glass melting pool unit kiln glass temperature slightly lower at the end of the transition path, forming the bottom of the pool and forming path path flow tank and bushing support brick etc.. In addition, the dense zirconia brick is used as the backing brick of the dense chrome brick.
Q:Can the PE sintering plate dust collector be suitable for dust removal in the coking plant?
The sinter plate dust collector is also called plastic plate dust collector. The utility model has the advantages that the utility model can adapt to various complicated working conditions, the dust removal rate is 99.99%, the utility model has the advantages of long service life, stable operation, high temperature resistance, and the utility model is a leading dedusting equipment in china.
Q:Expansion ratio of lightweight corundum refractory bricks
Now with the production of lightweight foam corundum brick, basically still meters with molding casting, moulding after together with die in the drying room drying in 60~70 C 4 days of release, then the appropriate drying, finally after 1300 and 1550 C firing, the total burning time: 50~60h. Light corundum brick after firing is usually not the size and shape of accurate, so that products after the kiln to mechanical or manual cutting, can be made into a density of 0.8 - 1.3g/cm3, 4MPa compressive strength and porosity, the thermal conductivity of 70%~80% 0.17W/ (M - K), light-weight corundum brick use temperature of 1500~1700 DEG C.
Q:How do corundum bricks bind?
High temperature bonding clay can be used for bonding masonry
Q:What is the difference between T3 refractory bricks and high alumina refractory bricks?
The T3 in T3 refractory bricks refers to the model indicating that the refractory brick model is T-3, and that the corresponding T-3 model is 230*114*65 (mm)
Q:What is the main component of corundum?
Corundum is mainly used in advanced grinding materials, watches and precision mechanical bearing materials. A ruby based artificial crystal used as a laser emitting material. Ruby and sapphire are corundum minerals. Except for the starlight effect, only translucent transparent and vivid corundum can be used as gems. The red is called ruby, while the other tones of corundum are commercially referred to as sapphires.
