$Dry Impermeable Refractory Material$

Q:What is the mechanism of the errosion of the iron to the refractories?: For example, the effect of the iron oxide: Mo corundum given temperature Fe2O3 solid solubility limit of the solid solution formed of corundum stone high solubility than the solid solution Mo Mo corundum lattice shape so Fe2O3Al2O3-SiO2-based material starts melting temperature of the system or the content of Al2O3 and Al2O3 / SiO2 ratio off Al2O3 / SiO2 & lt; 2.55 starting melting temperature of 1380 ℃ when Al2O3 / SiO2 & gt; 2.55 start melting temperature is increased 1460 ℃ and with its Al2O3 content increased gradually to increase the original atmosphere Fe2O3 original FeO off the solvent into the glass phase and the system starts melting temperature drops do not fall to 1240 ℃ 1380 ℃. Lower the melting point, increase the erosion, and reduce the life span.

Q:What are the differences and connections between softening temperature of the refractory under a fixed load and thermal resistant creep property of the refractory?: The result of refractoriness under load is temperature while the result of creep is percentage of deformation. Refractoriness under load and creep can be tested by an instrument. Refractoriness under load reflects the temperature in which the deformation reaches a certain degree under the condition of load. Creep reflects the deformation refractory has under the condition of constant temperature and load. Both refractoriness under load and creep are important criterion for the operating temperature of refractory.

Q:What type of firebrick does TZ-3 represent?: It is the standard brick.

Q:What kind of material is refractory fiber?: Refractory fiber, also known as ceramic fiber, is fibrous thermal insulation refractory. It has the characteristics of ordinary fibers, such as softness, flexibility, having a certain tensile strength. And it can be further processed into a variety of products such as paper, wire, rope, tape, blankets and felts.

Q:What refractory materials are used in power plant: Vacuum mud machine, sintering furnace! And then I will introduce some application of thermal material in power plant (below) I hope I can help you. Energy saving is the trend of future industrial development efforts, grinding machine, conveyor belt, so the production of light thermal insulation materials will gain state support, drying kiln. Our factory mainly produce light thermal insulation brick. The refractory material we use most is light insulation brick, and the equipment used is sand mixer (Luohe, Henan)

Q:What are the models of bauxite with high alumina?: China Ferrous Metal Industry Corporation released the industry standard of bauxite (YS / T78-94) in 1994. According to this standard, bauxite can be divided to sedimentary diaspore, stacked type diaspore and lateritic gibbsite. According to the chemical composition, it can be divided into nine trade marks as LK12-70, LK8-65, LK5- 60, LK3-53, LK15-60, LK11-55, LK8-50, LK7-50 and LK3-40. In addition to the provisions of chemical composition of bauxite, the standard also requires that the water of sedimentary diaspore shall not exceed 7% and water of stacked type diaspore and lateritic gibbsite shall not exceed 8%. Moreover, particle size of bauxite should be not greater than 150mm. Bauxite shall not be mixed with clay, limestone and other debris.

Q:How can refractory materials be divided?: There are many criteria for the classification of refractories.Just referring to a book about refractory.

Q:What is the difference between the fire?rating and the fire resistant level of the fire-fighting equipment?: Hello there. Fire rating and fire-fighting rating are the misnomer to the building fire resistant level. The building fire risk is measured by fire resistant level. The article 3.2.1 and 5.1.7 of "Architectural design code for fire protection" have made provision respectively on the fire resistant level of plant (the storeroom) and civil construction. Article 3.0.2 of "Code for fire protection design of tall buildings" has made provisions on the fire resistant level of tall buildings. As for the warehouse building "category malonate", it refers to one of the fire risk of goods storage, which is divided into A, B, C, D, E, and each category is refined depending on the nature of different substances. "Malonate class" specified in article 3.1.3 of "building design for fire protection" refers to the flammable solid.

Q:What are unshaped fire-resisitance materials?: Refractory castable, refractory plastic material, usually classified according to construction and manufacture method, unfired bricks precast block, refractory pressed into material, refractory cast material, refractory coating, refractory ramming material there are many classification methods
