Q: Kinds of refractory mortar: Refractory mortar can be divided into ordinary refractory material and special refractory material. Ordinary refractory materials can be divided into acidic, neutral and alkaline refractory materials chemical properties. Special refractory material can be divided into high temperature oxide, refractory compounds and high-temperature composite materials according to their components. Furthermore, according to refractoriness, it can be divided into general refractory products (1580 ~ 1770 ℃), high grade refractory products (1770 ~ 2000 ℃) and super refractory products (2000 ℃ above). It can be divided into bulks (standard bricks, special-shaped bricks, etc.), special shapes (crucible, sagger, pipe, etc.), fibrous (aluminum silicate, zirconia filter and boron carbide , etc.) and indefinite shape (refractory clay, pouring materials and ramming mass, etc.). According to the sintering process, it is divided into sintered products, fused cast products and melting jetting products.

Q: What's the requirements of fire-fighting criteria of heat insulating material?: It shouldn't be under than B2 level. Roofing insulation fire rating requirements: the ministry of public security, housing and urban-rural development department issued about printing and distributing the civil building external thermal insulation system and the interim provisions on the exterior wall decorative fireproof prescribed in the notice: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm.

Q: Who knows the classifications of magnesia refractory?: They can be devided into two major categories of fettling magnesite grain and magnesite products. They can be divided into fettling magnesite grain, magnesia?brick, magnesia-silica brick, magnesia-alumina brick, magnesium-calcium brick, magnesia-carbon brick and other varieties according to the chemical compositions and purposes Its performance is greatly affected by CaO / SiO2 ratio and impurities. The load softening point and thermal shock resistance of high purity magnesia brick are much higher than those of the general magnesia bricks. It has high refractoriness and good resistance for alkaline slag and iron slag, which is an important kind of advanced refractory material. Magnesia products are mainly produced by sintering, and sintering temperature is generally between 1500 ~ 1800 ℃. Besides, chemical binder can be added to make unburned?bricks and unshaped refractories. Mainly used in open hearth furnace, electric furnace, oxidation converter, non-ferrous metal metallurgy furnace, cement kiln and calcining kiln for basic refractory.

Q: Using what kind of melting aluminium furnace refractories is more appropriate?: If it's the ordinary, you can use high aluminum refractory brick with general clay, GB/T 3994-2005 clay heat insulation refractory brick. If you need these with good material, there is high alumina thermal insulation refractory brick, GB/T 3995-2006 high aluminum heat insulation refractory brick, models have A13 and material is the alumina, A13 50 u, high insulating brick B5.Intermediate insulating brick B2, etc. Dolomite brick: good hang kiln performance, good erosion resistance, but brick is usually without f - CaO, hydration, and difficult to transport and storage, less used in the production. Magnesia-chrome bricks: good hang kiln, used in calcining zone. The disadvantage is that its thermal shock resistance is poor and plus hexavalent Cr is toxic, the production and use of magnesite chrome bricks in international countries gradually reduce. Now unit using the brick find replacements as soon as possible.

Q: What is the most reasonable drying heating curve of magnesia refractories? Products of less than 0.5T: o

Q: How to choose refractory material: Refractory fiber according to different raw materials, there are aluminum silicate, quartz, alumina and graphite, refractory fiber. Commonly used aluminosilicate refractory glass fiber is amorphous, including ordinary aluminum silicate fiber, high-purity aluminum silicate fiber, chromium silicate fiber, long-term use temperature of 1000-1200 degrees.

Q: Does the refractory material used in steelmaking all refer to refractory brick?: It includes not only refractory brick but also unshaped refractory; while the foaming?agent, ladle filler sand and deoxidizer are not refractory materials but ferrous metallurgy auxiliary materials.

Q: who knows the fire resistant level of fireproof gypsum board ?: Gypsum board is flame retardant materials, combustion performance rating B1, but when mounted on a steel joist, it can be seen as rating A(non-combustible material) . So it is fine to use as a ceiling. As for the Dragon brand, rock wool can be filled in the mddle according to its design requirements, using different series of gypsum board, steel stud. the walls may have fire resistance and sound insulation property of various degrees. You can randomly choose several samples to run some tests at the quality inspection insititute and the quality of these samples are subject to the testing results.

Q: What are the components of refractory clay?: The component of refractory mortar comprises refractory powder, binders and admixtures. Almost all the refractory materials can be used as the powder to formulate refractory mortar. Ordinary refractory mortar is made from refractory chamotte powder, an appropriate amount of plastic clay as binding agent and plasticizer. It has low strength under normal temperature, but the ceramic formed under high temperature has a high strength. Refractory mortar which is formed with bonding material of hydraulicity, gas or thermal hardness is called chemical binding chamotte refractory mortar. It is hradened through chemical reaction before below the temperature of ceramic bonding formation.

Q: How to distinguish the fire resistant level of construction materials?: Division of fire resistant level of building material: 1, It can be divided into five levels according to the importance: a, special class: commerative, historic, international and national buildings. b, Class A: high-grade residential architecture and public building. c, class B: middle-grade residential architecture and public building. d, class C: orinary residential architecture and public building. 2, It can be divided into four grades according to fireproof?performance: Fire resistance level buildings is divided into four levels. Standard of fire resistant level is based on the combustion performance and fire endurance of main components of the house. 3, It can be divided into 4 levels according to durable life: a, A grade durable life, over 100 years, for important buildings and high-rise buildings. b, second level durable life, from 50 to 100 years, for ordinary buildings. c, third level durable life, from 25 to 50 years, for secondary buildings. D, fourth level durable life, less than15 years , for temporary buildings. I hope my answers will help you.
