Product Description

Low Porosity Clay Brick

This product is mainly used in glass heating chamber with features of low porosity, strong corrosion resistance, etc. To meet different environmental need of glass kiln, it is made in three serials according to corresponding process formulas: DN-a, DN-b, DN-c.

Al2O3 (%)	45	42	40
Fe2O3(%)	1.2	1.5	2.0
Refractoriness (℃)	1770	1750	1730
Refractoriness Under Load (KD℃)	1470	1450	1400
Apparent Porosity (%)	13	15	17
Bulk Density (g/cm3)	2.35	2.30	2.25
Atmospheric Pressure Strength (MPa)	75	60	50

Q:What's the weight of the refractory bricks?: Referred to as refractory brick. Refractory made from refractory clay or other refractory material. Light yellow or brownish. The utility model is mainly used for laying smelting furnaces, and can withstand high temperature between 1580 DEG C and 1770 DEG C. Also called brick. Refractory material of a certain shape and size. According to the preparation process can be divided into bricks, brick, electric melting brick, refractory insulating bricks (Rong Zhuzhuan);

Q:What materials are used for roof insulation?: There are two kinds: one is a kind of cotton insulation board, such as rock wool board, aluminum silicate cotton board, but this is not environmental protection, harmful to life, foam board (this fire safety factor minimum), these relatively cheap.

Q:What is the high temperature limit of refractory bricks and refractory soil?: Fire clay -- usually refers to folk point stove furnace set with a kind of soil, limit under atmospheric pressure of 1500 degrees fire clay soil 1, properties and uses: clay brick of weak acid refractory material, its thermal stability is good, suitable for hot blast furnace, boiler and flue, smoke chamber lining, etc..2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.

Q:Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of high temperature refractory brick?: The super high alumina brick in high alumina refractory brick has the highest refractoriness, and the corresponding production cost is higher.

Q:What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?: All the raw materials adding order, mixing time, material and material moisture trapped. 4, the pressure and the volume density of Pei brick and brick Pei size etc..

Q:Which is faster for heat transfer between corundum bricks and high alumina bricks?: There must be a difference. They vary in color from the amount of aluminum, the weight, the temperature, and the color.

Q:Which thermal shock stability of clay brick and high alumina brick is good?: Generally, the thermal shock resistance of high alumina brick products is worse than that of clay brick products

Q:Which is better, the soft core or the hard core?: When the current through the wire, it will produce a magnetic field in the vertical plane space of the wire, if there is a current two wire close by in the same direction, because they produce a magnetic field in the direction is opposite, it will produce a repulsive force is due to the magnetic field force. They will mutually inhibit current intensity of the other party, caused by the reduction of current in the wire, this inhibition of each current intensity, we called wire inductance. When the AC current line frequency is high, the inductance is stronger.

Q:The difference between aluminium refractory and magnesia refractory: Therefore, the difference between the two is a neutral, one is alkaline, the original product is different naturally.

Q:What are the main components of high alumina bricks?: High alumina brick materials according to the main mineral phase can be divided into: aluminum silicate minerals, such as sillimanite, kyanite, andalusite, and synthetic mullite.
