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 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:Which is better for tunnel kiln suspended ceiling, refractory brick or ceramic fiber module ?
It's certain that refractory brick is better.
Q:What is the heating temperature in the test method of thermal shock resistance of refractory bricks
1, quenching (air cooling or water cooling), after the completion of the specified number of times. 2, maintain 20min, introduce the following types briefly. 3, repeated testing and record the times of the material produces macro cracks. The thermal shock resistance is shown by the times of thermal cycle of damaging half of the heated end face, quenching(air cooling or water cooling ) there are many expressions and testing methods of the thermal shock resistance, and then dry. Put the heating end surface of standard size brick((200~230mm) X (100~150 m K (50~100mm) claw)into the preheated to 1100 DEG C 50mm in furnace, quenching (air or water), then quenching in room temperature water for 3min, measured the maximum temperature of sample surface produces cracks. After the temperature of the material rises to a predetermined temperature, the ratio of residual anti-bending strength and anti-bending strength at room temperature before heat shock, after the material rises to various temperatures, measure its strength retention rate.
Q:What is the relationship between the firing process and the manufacturing technique of fireclay bricks?
Q:does furnace use refractory cement to make refractory bricks?
You can use fireclay, refractory cement is commonly used to arch. fireclay has good viscidity, it is handy to use.
Q:What is the color of the refractory brick to repair the same color as the 1400
Smash the same brick into fine powder
Q:does all the refractory refer to refractory bricks when making steel?
chamotte, castable refractory, etc are shapeless refractory, above are all ferrous metallurgy auxiliary
Q:Why are the refractory bricks near to rotary kiln tyre easy to be short lives?
Q:How many degrees of refractory brick if its surface turns red, how to test the temperature of refractory brick after it is burnt to red.
Dark red? Bright red? Orange red? 400,1100 or 1500 probably
