Q:What is the strength of high strength refractory material?: With the help of high temperature and load, refractory material deforma to a certain degree of temperature from the beginning of deformation (load softening point), known as high temperature structural strength or high load softening temperature. It is a the ability to resist deformation ih high temperature and load at the same time. The nature of the high temperature is very improtant for selection of a furnace building materials under the effect of high temperature and force.

Q:Why do magnesium oxide refractory bricks can be made into refractories?: The substance used in refractories must have the following characteristics and properties: 1, High stability: Anti-oxidation, anti-reduction and thermal decomposition; 2, High melting point of 2800 degree; 3, Low price. The magnesium oxide refractories have all these three characteristics and properties, particularlly in the aspects of melting point and stability .

Q:What are the differences between first-level fire-resistant materials and second-level fire-resistant materials?: 1, these refer to fire resistance rating of building materials. 2, As for steel, elements that used in different parts should reach different duration of fire resistance according to fire resistance rating. For example, fire resistant pillars of first level can endure fire within 3 hours; the second level, 2.5 hours; the third level, 2 hours. With respect to beams, three levels of fire resistance are included.

Q:What types of steel are silicious quicksand and chromium quicksand used in respectively?: Chromium quicksand can be used in steel-making process that has longer refining time like LF, VD and RH, in stainless steel drainage and thin plate drainage agent. Silicious quicksand is used in short steel-making process, process that is less than 45 seconds or process without refining. You can consult Hua Heng for details or inspect it by yourself.

Q:What are the characteristics of thealuminium oxide refractory?: Physical properties of refractories include structural properties, thermal properties, mechanical properties, performance and job performance. The structural properties of refractories include porosity, bulk density, water absorption, air permeability and pore size distribution. The thermal properties of refractories include thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, thermal diffusivity and thermal emission rate, ect. Mechanical properties of refractories include compressive strength, tensile strength, flexural strength, torsional strength, shear strength, impact strength, abrasion resistance, creep resistance, adhesive strength and modulus of elasticity, ect.

Q:which kind of refractory is commonly used in the industry: Therefore it is known as special fire-resistant materials, such as yttria, high alumina raw material (sometimes neutral), olivine,which is used for alkalinity furnace, dolomite, and we roughly divided into several categories, beryllia, cerium oxide, these materials have a strong alkaline slag resistance, thorium oxide, lime, serpentine, which is picked from these refractory raw materials. the raw materials of basic refractory materials are mainly magnesia clay and titanium oxide, but because not many sources of raw materials, it can not be widely applied in the refractory industry, and we can analyze which kind of materal is processed by the pulverizer. There are many kinds of refractory materials, rotary?kiln can only be used in particular circumstances. These materials have a variety of slag resistance at different degrees. the main material of special refractories is zirconium oxide. the refractory clay is the most basic and most widely used raw material in the refractory industry.

Q:What is the type of heat resistance property of high temperature electric furnace ?: According to the levels of refractoriness : Common refractories: & Gt: 1580 ℃ ~ 1770 ℃ advanced refractories: 1770 ℃ ~ 2000 ℃ AAA refractories; 2000 ℃

Q:How long is the duration of fire resistance of autoclaved flyash-lime bricks?: How long is the duration of fire resistance of autoclaved flyash-lime bricks?

Q:What is the difference between wear-resistant material and refractory material?: However, the purity and the requirement are not the same. For example, brown emery is often used in abrasive paper, which doesn't matter. Refractory material uses brown corundum brick. The material used in texture and refractory material of abrasive is different. For example, it is to facilitate their forming and easy sintering. However, some other materials should be added when making brown corundum brick. In general, some top grade materials are used to make abrasive.
