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

Q:How can the silica in zircon sand be removed during the smelting of zirconium corundum?

How can the silica in zircon sand be removed during the smelting of zirconium corundum?The fused zirconia corundum brick is mainly made of fused zirconia and corundum. ZrO2-Al2O3-SiO2 three element system fused brick, containing Al2O3:40% to 50%, ZrO2:30% to 50%, SiO2:10% to 17%.

Q:What's the weight of the refractory bricks?

Fireclay refractory bricks: 3.4kg-3.8kg - according to the quality of raw materials, prices ranging from 1 yuan to 2.7 yuan, high alumina refractory brick: three, high aluminum in 3.9kg or so. Ordinary T-3 firebrick weight calculation method: 230*114*65*2.2/2.1.

Q:What material is good for refractory bricks?

No definite answer can be given, because any furnace is not made of only one refractory brick and needs a different fire brick to be used with each other.

Q:What are ordinary bricks, refractory bricks, hollow bricks?

Referred to as refractory brick. Refractory wood made from refractory clay or other refractory material

Q:Zirconium corundum 25 content and 40 content, how to distinguish in appearance?

It is in the production process, zirconium corundum bricks are likely to cause pollution.

Q:Outside wall tile (whole body smooth surface has small hole split brick) has cement pollution, with what product cleaning (cement, mortar, cleaning agent)?

Tile has a long period of cement pollution, a variety of weak acid cleaning can be removed, such as oxalic acid, acetic acid and so on, of course, the use of special cleaning agent is perfect. But the cost is higher.

Q:Is the wall around the fire area using a firewall? What's the difference between a fireproof brick and a regular brick?

Fire bricks burn well!!In fact, the firewall does not necessarily have to use the so-called "fire brick", but to see the brick fire limit!240, the fire limit seems to be 4 hours, 370 I do not remember clearly, fire codes have, you see, do not think so naive!

Q:What are the categories of bricks?

Ordinary brick size of 240 mm * 115 mm * 53 mm, according to compressive strength (Newton / square millimeter, N / mm2) size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these intensity levels. Clay brick materials, cheap, durable, and fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, is widely used in civil engineering. Waste brick can also be used as aggregate of concrete. In order to improve the shortcomings of ordinary clay bricks, such as small, self important and waste of soil, they are developing in the direction of light weight, high strength, hollow and big blocks.

Q:Can the fire clay be reused?

Refractory soil cannot be reused.Clay refractory soil 1, characteristics and uses: Clay refractory brick is a weak acid refractory material, its thermal stability is good, suitable for hot air furnace, all kinds of boiler lining, and flue, smoke room, etc.. 2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.
