Q:What are the models of refractory cables?
NH is the firat letter of "refractory" in Chinese phonetic alphabet; It is V, not W. PVC insulation and sheath; K in KVV represents the control cable. 5 * 10 represents the cable is made up of 5 core cables whose nominal cross section is 10 square milimeter.
Q:How much refractory material is needed when 1 million ton coke oven is produced?
Q:Does refractory belong to metallurgical auxiliary materials?
Refractory is widely used in industrial circle, such as metallurgy, chemical industry, petroleum, mechanical manufacturing, silicate and power, and its coonsumption is the maximum in metallurgy, accounting for 50% to 60% in total output. In order to improve slag-corrosion resistance of furnace lining, usually choose carbon-containing refractory. Refractory of various furnace lining are respectively: For the body, it is clay brick; as for the lower part, bosh and middle, it is SiC brick; for furnace bottom, it is carbon brick. Lattice brick is an important refractory product used in air heating furnace and regenerative chamber. Refractory is widely used in metallurgy. In order to improve slag-corrosion resistance of lining. Central line in tuyere and hearth are high-alumina brick. Refractory consumption is the maximum in metallurgy, accounting for 50% to 60% in total output. For the bosh and middle, it is SiC brick. In order to improve its thermal storage capacity: The furnace stack is clay brick. It is defined as refractory where the physical and chemical properties allows its use in high temperature environments; The lower furnace body
Q:Does the production of refractory belong to advanced technology?
It certainly is advanced technology as it is the new material.
Q:How is the development of Xinmi refractories industry? What's its advantages and disadvantages?
The advantages are largest scale, top production amout in the country, accounting for one-third of the national market, having technology, strength and the market. The disadvantages are the lack of mineral resources, serious environmental pollution,
Q:how does the fire endurance of first rate fire resistant window?
class A window not less than 1.5 hours, class B window not less than 1 hours, Class C window not less than 0.5 hours.
Q:What crusher is used for raw material of broken refractory material? What is the rough crushing process? What are the materials? Thank you!
What are the requirements of granularity of material?
Q:Why does refractory need to add coarse firstly and then add fine aggregate?
Binding agent can wrap particles and improve binding effect.
Q:I wanna ask that magnesium oxide is refractory?
Magnesium oxide is used in refractory material, because it has the following characteristics and properties: 1, high stability: Anti-oxidation, anti-reduction, thermal decomposition; 2, high melting point, 2800 degrees; 3, low prices. In particular, the stability and melting point is very good, I hope I can give you help.
Q:What types does refractory floor include?
It includes ecoplates, chipboard,density board, composite board, etc. Wherein ECO-plate is solid wood board, and it is environmetanl and healthy. Its nail-holding ability and flatness is much better than that of chipboard and solid wood particle board. After all it is solid wood board. But we must pay attention to whether the eco-board is produced in the original factory. According to our original factory, the board only produced by Treezo Group and Dede board are the original.
