Q:Who knows that among refractory materials, insulation boards from which refractory material industry is superior in quality?

When casting ingot, after high temperature molten steel is poured into ingot mold, molten steel keeps shrinking during cooling, for example, killed steel is shrinking 3% --5%. because of fast heat dissipation of ingot head , some shrinkage holes appear at the head of ingot. Therefore, you should cut shrinkage holes which account for more than 15% of the ingot quality in the head while cutting steel ingot cogging. If effective measures were taken to insulate the head of ingot from heat, then the coagulation time of ingot head would lag behind in the body of the ingot solidification, which will greatly shrinkage holes, improve ingot yield so as to reduce energy consumption of steelmaking. Adiabatic plate can achieve this purpose. China Heng insulation board has the advantages of uplifting adiabaticity and small heat capacity, so that it greatly reduced heat loss of molten steel, And the tundish can be directly put into use without preheating, thereby saving a large amount of preheating fuel. So in the current process of continuous casting, the heat insulation board is the main material of tundish lining.

Q:What needs to be noted when choosing and using blast furnace fireproof materials? Who knows?

there are different temperatures in various parts of the blast furnace, thus using different types of refractory.

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:The following statement is correct: artificial corundum has a high melting point and can be used as a high grade refractory material. The main component is silica dioxide

Artificial corundum has high melting point and can be used as high-grade refractory material. The main component is silica, and the main component is aluminaThe chemist uses agate mortar friction solid reactant without solvent synthesis, the main component of agate is the main silicate is silicon dioxideThe early construction of the Three Gorges dam uses a lot of cement, which is made of silicate materialIn the summer, tourists wear by adding cuprous oxide silica made of glass color glasses to protect eyes [] color glasses is added to the material made of silver, it is now possible to have more advanced material, but the middle school stage is said with silver bromideIt sees light, decomposes easily, and combines easily, so use it.Solar cells can be made of silicon material, and its application is favorable to environmental protection and energy saving

Q:what is the Specifications Grading for Fireproof rubber insulation materials ?

At present, China Building Materials has two grading criteria for combustion performance. "Combustion Performance Classification Method of Building Materials" and "Combustion Performance Classification Method of Building Materials and Products" (GB8624-2006). Among them, one of the major changes of GB8624-2006 and GB8624-1997 is to divide the material combustion performance grading from homogenous material)Class A (composite sandwich material), B1, B2 and B3 level five minutes as A1, A2, B, C, D, E, F seven levels.

Q:Can quantitative feeder be used in refractory plant? Thank you

Well, can the Weifang Sanyou automation equipment production chain plate feeder is fully applicable to the measurement and control of boring high temperature, chain plate feeder with 16 4-5MM manganese plate.

Q:I wanna ask that magnesium oxide is refractory?

Magnesium oxide. magnesium oxide has high refractory insulation properties. After above 1000 ℃ high temperature burning, it can be transformed into crystals. And it can be transformed into dead-burned magnesium oxide or sintered magnesia oxide until rising to above 1500 ℃. It has heat-resistant, non-conductive at room temperature and relatively poor thermal conductivity. Magnesium oxide is mainly used for the preparation of ceramic, enamel, refractory crucible and refractory bricks. I hope to help you

Q:How to make the service life of refractory materials longer?

Take acid resistant refractory materials as example: the atmosphere should be acidic atmosphere, if used in an environment whose temperature is 1900℃, it would exacerbate the loss of refractory materials, so don’t use overloaded. Second, select the appropriate refractory materials according to the environment. For example, if its operating temperature is 1800℃, generally speaking, the normal use of it according to the instruction of refractory materials would be fine.
