Q:How to prolong the furnace age of Induction furnace by using fireproof materials?
magnesia solid materials have thermal endurance and erosion/ performance and its change of temperature is likely to cause cracks. properties of materials (aluminum) in such case have to be taken into consideration.
Q:Which refractory material is better in China? Industrial furnace, mainly in non-ferrous industries, glass kiln, cement kiln business.
Such solid nano microporous insulation material with nano inorganic refractory powder special, with a huge surface area, nano particles contact between the minimum point contact point contact thermal resistance is very large, the heat conduction effect of the material becomes very small, resulting in heat conduction coefficient of solid such nano porous insulation materials very small; nano pores formed of nanoparticles, the average size of 20 nm, and the average free path of molecular thermal motion at room temperature under static air is 60 nm, thus locking the air molecules in powder within nano pores, making the micro convection heat transfer effect between the stationary air molecules disappeared. The room temperature thermal conductivity of solid such nano microporous insulation material is lower than the static air; at high temperature, the main effect of heat transfer heat radiation, Good energy-saving insulation materials with nano microporous infrared additive special, stop at a high temperature and reflected infrared radiation, reduce the heat radiation effect to the lowest point, the radiation heat transfer coefficient of materials under high temperature is reduced to the lowest value.
Q:What is the concept of lightweight refractory material?
Lightweight refractory material has high porosity, mechanical strength and erosion resistance. Compared with normal refractory bricks, it is a kind of refractory material with large volume shrinkage in high temperature, low thermal conductivity and small bulk density. It is used as thermal insulation material in industrial furnace and other thermal equipments. It has poor wear resistancel.
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
Q:Selection of refractory materials?
Basic refractories in Magnesium Oxide and calcium oxide as the main ingredient, commonly used is brick. Magnesium Oxide 80% to more than 85% containing magnesia brick, has good resistance to alkaline slag and slag, refractory clay brick and brick high ratio. Mainly used in open hearth furnace, oxygen converter, electric furnace, non-ferrous metal smelting equipment and high temperature equipment.
Q:What is molten silicon? What refractoriness do refractories made by it have? What properties of using does it have?
Molten silicon can be called quartz glass, which shows an amorphous silicon state. It is a liquid fusion at above 1723 degree and is an ultra-cooling state at low temperatures. It is not generated in refractories, but generated in the matrix, showing liquid state at a high temperature capable of buffering the stress with somewhat binding properties. If quartz glass is used as refractory, its function are melrly these ones. (These are what I konw for reference only.)
Q:Which are fire proofing thermal insulation materials?
Grade-A fire proofing inorganic thermal insulation materials include rock wool, glass wool, vitrified micro bead, foaming cement, foaming ceramics, vacuum thermal insulation board,
Q:I would like to know if there is any requirement for refractories in the crucible type high-frequency smelting furnace Worry! I hope you can help me! This time!
Good thermal stability, the crucible wall hour working temperature fluctuation is great, and the temperature field distribution is uneven, so the crucible wall will continue to produce volume expansion and contraction, resulting in cracks, which directly affect the service life of the crucible
Q:Does the aluminum silicate thermal insulation material fireproof?
How does its fireproof performance? this is the material that the decoration master worker recommands to me, how do you think of it?
Q:How many kinds of A-level fireproof and thermal insulation materials are there?
Shenyang polystyrene board, extruded sheet, polystyrene particles, and polystyrene plastic plates...
