Manage of brick of tall aluminous light qualitative heat preservation changes index to the intensity of body close density, compression, heavy change that burn a line, coefficient of thermal conductivity, material pledges content and impurity reach use temperature to wait, kiln furnace liner undertakes selection according to using a requirement, had these index to be able to know whether this product can be used, the manage of fireproof material changes index to detect is by many special apparatuses equipment is undertaken detecting of assay, flourish Cheng Naicai owns the testing instrument facility of a complete set of, offer be able to bear or endure material research and development, offer high grade product for broad client, and offer construction serve, the welcome comes to a factory make an on-the-spot investigation, negotiate, cooperative win-win.
The use temperature of light qualitative firebrick pledges firebrick is to show hole leads density of tall, bulk gently the fireproof product with small, low thermal conductivity. Light qualitative firebrick has poriferous structure (hole rate is commonly 40% , the characteristic with 85%) and adiabatic tall sex. According to the use temperature of light qualitative firebrick, are there a variety of classification: ? Buttock is walked on dash forward ℃ of?00~900 of dew of dream of A Chinese-style unlined garment of Hu , be like diatomite brick, asbestine brick; In lukewarm firebrick; ℃ of use temperature 900~1200, be like brick of vermiculite, light qualitative clay; Light qualitative tall aluminous brick; Firebrick of high temperature heat insolation uses temperature to exceed 1200 ℃ , if pledge gently,corundum brick, high temperature not comes brick of stone heat insolation. Industrial kiln uses adiabatic firebrick to have a lot of advantages, it is managing the sources of energy is used up, general but managing 2/5~3/5; 2 it is to reduce weight of body of heater, simplify kiln system structure, drop environmental temperature, improve working condition; 3 it is kiln can warm up quickly cooling, raise equipment to manufacture efficiency. But rate of hole of light qualitative firebrick is old, the organization is inattentive, the sex that fight broken bits is poor, slaggy and rapid invade bricky aperture inside, make its broken, cannot use at direct contact slaggy the place with liquid metal.
How much is the price of brick of tall aluminous light qualitative heat preservation? The advantage of light qualitative tall aluminous brick is long-term high temperature resistant performance is good, defect is difference of heat proof quality. The hole in light qualitative firebrick can burn the light aggregate such as material, vesicant or hollow ball to be made through adding, the size of aperture is opposite bigger. These aperture not only adiabatic effect is not tall, and the mechanical performance that affects a product. If stomatic bulk mark increases, collect of a lot of large hole assemble are together, affect the intensity of adiabatic brick. However, the area comparing a list of light qualitative firebrick is smaller, lower than the surface. Accordingly, thermodynamic stability is better. After heating for a long time, not allow to pledge changeably. Do you need to know to pledge how much the price of firebrick is gently? Must clear up the following problem: 1. The particular use case of the kiln heat that you use, if use temperature, whether to contact blaze to wait. 2. Does the kind that wants light qualitative firebrick include: normally? A screen-like mountain peak receives ┑ of of word of of oath of a screen-like mountain peak of ⑶ of of fleeing phosphor of Xia of ⒐ of of phosphor of thing of a screen-like mountain peak of ⑶ of punish phosphor to take herd of U Wu ┎ is? of of brilliant of arm of collect Zou a surname. Know the value of light qualitative firebrick.
The fireproof sex of brick of tall aluminous light qualitative heat preservation detects method. Fireproof sex is the character with high temperature resistant material. When raw material of 3 kinds of concentrate uses stone of line of cyanite, andalusite, silicon, need measures his fireproof sex, in order to understand the purity of raw material. If foreign matter composition, have the foreign matter of strong flux function especially, fireproof sex can be reduced. Of fireproof sex determine methodological: ? dash forward herd of ancient name for a kind of scorpion of Jiao small box shows of fan of shoot a glance at to kiss fourth H to wrap up accept shipboard in person rash ざ holds the post of? millimeter, length are 8 millimeter, height is 30 millimeter. Put awl of high temperature standard in next same on cone, in the regulation warm up heat below speed, compare sample awl and standard awl photograph. As a result of the occurrence of photograph of high temperature fluid, sample awl gradually bate, the gravity that passes its oneself curves bottom. When cone coping bends and coming down to contact cone, temperature is fireproof. At the same time with sample number of bent standard awl shows fireproof gender. Be in fused before beginning; B- falls in the temperature that is equivalent to fireproof sex; C- is able to bear or endure in prep above below the temperature of bad temper. A few concepts need to make clear: (The meaning of 1) fireproof sex and melting point is different. Melting point is fuse from solid liquid balances temperature. Fireproof sex is all sorts of mineral fused limits. Really, the melting point with mineral crystal is high, what interaction forms is low in all the temperature of frit content is high also. (2) fireproof sex cannot misunderstand the temperature that can use below high temperature for fireproof material. Because it is already complete,bate arrives lose mechanical strength. For example, the combinative part of alkalescent and fireproof material fuses first in inferior temperature right-hand seat, its caustic is based on the bate of bond, far the fireproof sex under material. Generally speaking, the use temperature of argillaceous brick is mixed under 200 ℃ 250 ℃ .
Of density of bulk of brick of tall aluminous light qualitative heat preservation determine the dry quality that methodological bulk density is fireproof material and its are overall indigestion (aperture of solid, mouth and the total volume the sum of the aperture that close a mouth) than, namely the quality of data unit volume, express with G/cm3 or Kg/m3. The bulk density of sealed and fireproof product should decide according to national level GB/T2997-2000. The bulk density of sealed and fireproof product should accord with national level GB/T. Measure time to be 2998-2001. Sealed and fireproof pouring the bulk density of makings should decide according to YB/T5200-1993. Bulk density is the compact sex of fireproof material, it is one of main index of all and fireproof material and standard of fireproof product quality. The bulk density of material is right sex of shake of temperature of bate of porosity, intensity, corrosion resistance, bear, wearability, heat-resisting other a lot of function have showing an effect. To light qualitative heat-insulating material, pledge brick, gently like heat insolation pouring makings, bulk density also is mixed with hot conductibility closely related thermal capacity. Generally speaking, material bulk density is high, be helpful for temperature of bate of its intensity, corrosion resistance, wearability, bear.
GB/T36133-2018 fireproof material, method of hot conductivity experiment (platinic resistor thermometer law) this standard was announced on May 14, 2018, carried out formally on April 1, 2019. It is limits. Measure of the principle that this standard set to platinic resistor thermometer measures fireproof material coefficient of thermal conductivity, equipment, sample, installation, test, result is calculated and check a report. This standard applies to the coefficient of thermal conductivity that measures the fireproof material that does not contain not carbon, electric, coefficient of thermal conductivity not to exceed 15W/(mk) . Note 1: ? The neck sunlights envy seeks dainty dizzy dew truly paragraph chair annulus?500 ℃ , test temperature upper limit also depends on the temperature that the operating limit temperature of material or fireproof material become conductor. Notice 2: - general to be not homogeneous materials, contain fibrous material especially, get accurate test is worth very hard. When this kind of method is testing these material, need related side talks things over consistent. 2 it is normative citation. The following file is crucial to the application of this file. The citation that fixes date only apply to the article. File. Any not the citation of dated, its are newest version (include all modification lists) apply to this file.
