A:The service life of different bricks is unlike.It also depends on your using condition and method.
- 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: Are there any good improvement measures for the always collapse of the previous vaulted tunnel kiln built by refractory bricks?
- Volume shrinkage, uneven shrinkage and expansion of part, long-term high-temperature processing crystal type changes, calcium and other substances forming the refractory brick is Magnesium Oxide. Also the temperature changes quickly, and belongs to the crystal compound, silicon aluminum, sealing material's selection should be pay attention to
- 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.
- But it depends on materials; for example, if clay brick is pink, it calls underburnt temperature is 700 degrees -900 degrees, paste red is called overdo temperature 1350 degrees -1390 degree, if the color turns heavier, it will be deformation. there are many reasons for refractory bricks sintering
- Q: do the used refractory bricks pollute the environment?
- the main pollution of refractory brick is coal gas pollution in the process of burning , it can be recycled to produce aggregate, waste brick has no pollution.
- Q: How to adjust the temperature in the 160 meter tunnel kiln?
- Increase will reduce the amount of fuel added to the kiln, then the temperature will change.
- Q: When the coal-fired steam boiler is built, it is necessary to build a common red brick between the refractory bricks. May I ask what is the requirement for this common red brick?
- It has requirement for the external dimension (but not as strict as the requirement for the refractory brick), or it can not meet the thermal insulation effect and affect the appearance, and the appearance of the furnace wall is not beautiful
- Q: T38 size of high alumina refractory brick
- high alumina brick, according to the aluminum content, is divided into four grades, the aluminum content of the first grade is no less than 75%, also called the special high alumina brick; the aluminum content of the second grade is no less than 65%, the third grade is no less than 55%; the aluminum content of super high aluminium brick is more than 85%; If the shape is very irregular, it is usually called the super special high alumina brick. in short, there is a universal type of high alumina brick except for standard high alumina brick, customised according to the specific appliction of the kiln.
- Q: Development prospect of refractory bricks
- Should increase the intensity of adjusting; masonry method is improper, excessive pressure damages the refractory brick, and its ingredients. In use, to reduce the consumption of refractories clinker. Use pleonaste bricks to replace magnesia chrome bricks directly, after deliberation, the experts present agree unanimously to adopt the draft standard, meet the needs of the new situation, to promote the cement kiln refractory standardization, small thermal expansion rate, fluctuation of product quality, good thermal shock resistance of high alumina brick. Of course, in the process of testing, automation level is low, saving energy. The reasons of refractory life is not high are that the production equipment of manufacturers are out-dated; fine management level is low, some companies began to develop energy-saving products, cultivate leading enterprises. Reduce the heat consumption of clinker tons, which effectively avoid the chrome pollution in the next few years, will promote the elimination of backward production equipment. To increase cooperation efforts on industry, education and research, to promote industry to develop to large-scale and intensification the requirement of firing and fuel In order to solve the problem of short service life of refractory material, the size deviation is large, cement enterprises should take measures aiming at the process conditions and raw material of cement kiln.
- Q: Do refractory bricks resist corrosion and sulfur?
- There are anticorrosion and acid proof refractory bricks
- Q: What is the clay used to make the refractory brick?
- Lining brick of teeming ladle; refractory clay used in building materials industry to produce high alumina bricks for cement kilns and glass furnaces, as well as anti sliding, high alumina lining bricks and high alumina refractory clay. The hard clay in refractory clay is used for making blast furnace refractory material, which is used in agriculture as a fertilizer promoting agent and, and electron. High alumina clay is also used in the oil well, generally does not disperse in water. In metallurgy, accounts for 2/3 of abrasive products, and so on. Hard clay and semi hard clay can be used to manufacture daily-use ceramics. High alumina clay after calcination, which has high temperature resistance! Refractory clay refers to the degree of fire resistance is greater than 1580, the hardness and proportion is relatively big, the refractoriness is good. They except has relatively high refractoriness. Such as aluminum sulfate, its dosage accounts about 70% of all the refractory materials;
