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:What is the role of refractory brick, whether is there any books to introduce refractory bricks
Just as its name implies it is a fire burning, making stove is very good
Q:What is the name of the white clay refractory brick
Kaolin
Q:What are the differences between high alumina brick and high alumina refractory brick?
with the increase of the fire temperature and other indicators, Al2O3 content is also improving. the general content of Al2O3 in high alumina brick is more than 60% .
Q:What raw materials are used for making refractory bricks
That is silicon aluminum refractory brick/, it can be divided into five types:thermal insulation refractory brick, alkaline series refractory brick, refractory brick containing zirconium, carbonaceous refractory brick/. Refractory bricks are divided according to the ingredient of refractory. Refractory bricks are generally made from refractory clay (kaolin) or other refractory materials.
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:How to built refractory bricks as fitting between square and circle ducts
Build a big mushroom, and build the legs as square
Q:Do cement kiln refractory bricks have quality guarantee period? can them still be used for a long time's pile?
They of course can be used. The plant will produce some bricks for standby application in advance, so they put for a period of time is completely no problem
Q:What materials make of clay insulating fireclay brick?
Clay insulation bricks are general according to the different origins of raw materials, not the same
Q:can the refractory sand be used to make refractory bricks?
yes, a lot of refractory sand is made by broken refractory brick, they have the same function.
