Q:How much is the silica powder in refractory bricks.
It's not easy to construct, also need to consider the technical and economic indexes, DH3, 1 kg silica powder replaces 1 ~ 3 kg cement, which is the reason why silicon powder was not used and spreaded in concrete in past, choose some silica power fume. In general, with the smoke escaping by special capture device for collecting and processing To determine the mixing method of silica powder, when mixing silica powder, you should find out the optimal dosage in order to obtain the best results, as the study, the content is 5% ~ 30%, H, the mixing of super high strength concrete, use same amount of silicon powder to replace equal cement to main same fluidity, Microsilica or Silica Fume, it is mainly according to the design requirements, and does not reduce the amount of cement, sand and stone to adjust the optimal dosage of water reducer, when deciding the best mixing amount of silica fume, the concrete is too sticky, most use naphthalene water reducing agent.
Q:is it good to use firebricks to preserve the heat of rto furnace? Is there any other good ideas?
Operating noise is very low, having a very strong chemical stability: The thermal conductivity is lower than 0 at normal temperature, it not only reduced the cost of the project of RTO furnace, but keeps the indoor heat dissipation heat better and reduce noise pollution. the temperature of RTO furnace surface is low after using the ceramic fiber lining to keep the heat, thereby reducing the addition of auxiliary fuel : ceramic fiber has a good thermal shock resistance: The dosage form of HLGX-589 and HLGX-312 ceramic fiber material is shown in figure RTO furnace thermal insulation material. C, good thermal shock resistance, without reserving expansion joints, ensure the lining intact, not easy to be affected by the harsh combustion atmosphere inside the RTO furnace, can deal with the temperature changes caused by periodic replacement of RTO furnace inlet. The furnace is new energy-saving furnace developped recent 30years that used for eliminating harmful exhaust gas caused by steel or paint spraying. it has long service life, high chemical stability, no heat preservation precedent for refractory bricks; B, good heat insulation effect.
Q:There are various refractory materials inside many kilns such as refractory brick, what is the role of masonry of these refractory materials?
When the steel is made, and wear) to complete the purpose of steelmaking, the liquid inside the kiln is melted liquid steel (1550 DEG C), erosion, only the masonry of refractory brick (melt above 1550 DEG C and has a certain strength) can resist various effects of molten steel (melting
Q:What materials make of clay insulating fireclay brick?
The aluminium silicate refractories whose aluminium oxide content is 30% ~ 46% is called clay-based refractories. Clay products mainly consist of mullite, glass phase, cristobalite and quartz.
Q:What is the biggest difference between refractory bricks and clay refractory bricks?
Q:What are the differences between thermal insulation bricks and refractory bricks?
Thermal insulation brick has low fire resistance, generally is porous and light.
Q:In tunnel kiln, what is the meaning of refractory proportion 2.0?
The proportion of refractory bricks is related to the density.
Q:What is the difference between the refractory bricks, hand-made bricks and the machine pressure bricks?
Withstanding voltage strength is not the same, the strength of the mechine-made is higher
Q:How to make refractory bricks? ? ?
Solution of the production of refractory brick raw materials
Q:What is the role of refractory brick, whether is there any books to introduce refractory bricks
Refractory bricks are generally used to build a hearth. Such as, boiler, furnace (molten metal), air heating furnace etc, the furnace need refractory bricks to bulid.
