NATURAL FLAKE GRAPHITE WITH GOOD DELIVERY TIME NFG

Q: Does anyone know the difference between refractory and thermal insulation material?: The main difference between insulation bricks and refractory bricks are as follows: 1. Insulation effect The heat conductivity cofficient of insulation bricks is usually 0.2-0.4 (average temperature of 350 ± 25 ℃) w / mk while the heat conductivity coefficient of refractory bricks is 1.0 (average temperature of 350 ± 25 ℃) w / mk or more. Thus it can be seen that the insulation effect of insulation bricks is much better than that of refractory bricks. 2. Refractoriness The refractoriness of insulation bricks is generally below 1,400 degrees centigrade while the refractoriness of refractory bricks is above 1,400 degrees centigrade. 3. Density Insulation bricks are generally light-weight insulation material, and the density is generally 0.8-1.0g / cm3. But the density of refractory bricks is above 2.0g / cm3.

Q: Is fireclay poisonous?: Refractory materials are typically oxides, alumina, magnesium oxide and aluminate cement and etc, which are non-toxic.

Q: Are the specification of fireclay bricks and ordinary clay brick the same?: The standard size of refractory bricks in our country is: 230mm × 114mm × 65mm; ordinary brick: 240 ×115 ×53, building blocks: (it is divided into blind hole and via) 240×390×190, 240×190×190, 240×90×190, 190×190×190, 190×390×190, 190×190×190, 190×90×190, 140×390×190, 140×190×190, 990×200×400, 0×390×190, 90×190×190, 90×90×190. Another is interlocked hollow block : 90×200×400，90×200×245，90×200×200，90×200×100，90×200×290，150×200×275，150×200×200，150×200×100，150×200×290.

Q: What is the fire endurance of ceramsite concrete blocks?: What is mentioned in fire?safety?rules is that the fire endurance of 240mm thick hollow brick of ceramsite concrete is 2.9h, so 190mm thick hollow brick is 3h. B05 thickness(mm), fire endurance(h). Combustion performance 100 4.0. Non-combustible component 150 6.0200 8.0300 〉8.0B06 100 〉4.0150 〉6.0200 〉8.0300〉8.0: The fire endurance performance of building blocks wall in the table is taken from the Tianjin Construction Standard "light steam pressing aerated?concrete?block" DB / T29-128.

Q: I am a manufacturer of refractory materials. I would like to receive some orders from abroad. I would like to know what foreign trade companies in Dalian place foreign orders abroad: You don't give a cent to this question, no one will answer it

Q: What refractories are used in various parts of the blast furnace.: Blast furnace from top to bottom has the throat, hearth staves, waist, bosh, hearth and furnace bottom. the specific structure is as follows: The throat is the first to be affected by the impact and abrasion, generally use high-density alumina bricks. the upper and central portion of temperature furnace is only 400 ~ 800 ℃, the area with high alumina bricks and silicate bricks. The lower part of furnace is subject to erosion and dust erosion alkali metal vapor due to high temperatures, it is required in such case to use high quality clay brick,high alumina brick,carborundum brick,corundum brick that is slag resistance and alkali?resistance, temperature resustant and wearproof. Furnace bosh temperature reached 1400 ~ 1600 ℃, serverly eroded by slag,vapor, flush. so we use carborundum brick and reaction-bonded silicon?carbide?brick. Bosh temperature reaching1600 ~ 1650 ℃, using alumina brick, corundum brick or silicon carbide brick. the temperature of Hearth near the upper portion of the outlet zone at 1700 ~ 2000 ℃, use of silicate bricks and corundum castable graphite filler, silicon carbide bricks. In 1450 Silly twitch bottom temperature sealing die of hunger slander bet phoenix astringent preserved Grade ~ 1500 ℃, use of graphite bricks and microporous carbon bricks, now use more corundum brick, corundum mullite brick and synthetic mullite brick. x26lt;P class x3d "share-btn"x26gt;

Q: What are refractory materials?: Refractories can be divided to two categories based on the shape and three categories according to the chemical nature of acidity, neutralily and alkalinity. Alkaline refractory materials are magnesia-carbon brick, magnesia chrome brick, calcium magnesium brick and magnesia-chrome bricks. Neutural refractory mateial are high alumina brick, corundum brick and clay brick. Case-hardened refractory materials are castable, ramming mass, gunning mix, coated mix, dry vibration material, etc.

Q: What are the best refractory materials in 2,400 Celsius degree?: You can try zircon sand which has a melting point of 2430.

Q: Can anyone tell me what is the material of which the mould for refractory is made？: W18Cr4V die steel

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)
