- Q: is it correct that the higher the refractoriness is, the better refractory bricks are?
- Does not necessarily, it has a great relationship with the compression and bending and corrosion resistance.
- 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 fireclay brick and high alumina refractory brick?
- One is the high alumina, solid and hollow respectively, fused mullite as main raw material made of high-grade refractory materials, strong corrosion resistance, has the advantages of through mud treatment, good thermal shock stability. Good resistance to slag, used to build steel making furnace and glass furnace. High alumina brick is a kind of refractory material. Clay brick is also known as sintered brick, electric smelting corundum and low creep high alumina brick [1] with high grade bauxite, this kind of refractory brick's main component is AL2O3, which is suitable for large and small buildings with artificial bulk. High thermal stability. A neutral refractory material with more than 48% of alumina oxide content, clay brick has clay (including shale, molding, coal gangue and other powder) as the main raw materials, cement rotary furnace lining. The product has a small high-temperature creep, one is clay. From bauxite or other high content of aluminium oxide raw materials' forming and firing, refractoriness is above 1770 deg. High R.U.L and medium-sized hot-blast furnace is different firstly in the material, forming from drying and roasting
- Q: which kind of refractory bricks do coke oven and oxtongue brick belong to ( ) A, silica?brick B, clay brick C, high alumina brick
- General use clay bricks, but the silica?brick is better, the price is expensive.
- Q: How about clay bricks?
- The strength of brick can be judged by the sound produced by two bricks colliding with each other.Two hands each take a brick, gently hit, such as a uniform, crisp sound, indicating brick high strength, good quality, if the collision sound hoarse or stuffy, it shows that brick strength is low.2. to observe the crack state of bricks, elliptical repeat crack if large surface of the brick on the head, like twistcore, called "spiral brick"; some bricks will be broken, the shell off angle, crack and other symptoms, hand picked up the pieces of a pinch, immediately in powder form. The inner core is yellow and honeycombed. It is called "crisp brick", which belongs to the waste brick.3. to observe the color of brick brick brick section: open, heart was uniform black, no unburned carbon brick, high strength of such. On the contrary, the intensity is low.
- Q: What is the advantage of the ceramic fiber material compared with the refractory brick?
- Ceramic fiber material is heavier than refractory bricks, property of machinery operation, low heat capacity, and has high anti-stretchability and good thermal shock resistance, low thermal conductivity make its thermal insulation effect is ten times than refractory brick, it won't has crack in sudden coolness and heat, and the construction is much easier than that of refractory brick, not delaying the production.
- Q: Can thick steel plate be used instead of the furnace inside the refractory brick?
- It depends on the temperature. The steel plate is a kind of heat conduction material which hasn't heat insulation, which should be based on the working environment.
- Q: how to test the high alumina refractory brick mixed alumina?
- Test
- Q: What is the difference between the refractory brick and the thermal insulation brick
- Refractory bricks are used in the stove, in order to prevent from burnouting the stove under high temperature. Thermal insulation brick is used for preserving heat, is to heat preservation
- Q: What is the perservation method for refractory bricks used for cement kiln?
- The hydration resistance ability is better than the alkaline materials, 1 years will be no problem if the environment is good, alkali-resistant bricks used in cement kiln brick refractory brick (magnesia-chrome brick, the preservative time will be longer, the remaining products should also be moistureproof. No matter what refractory materials, phosphate brick. If the package is complete, it must be stored in a dry and rain-proof environment, silmo brick. Anti-stripping alumina brick, if is not immediately used, it's necessary to take measures of moisture proof, such as spinel brick must be moisture-proof
