Q:whether the fire resistant level of aerated concrete building blocks can reach the grade one?

it has fire resistant level, incombustible?material,and it should reach grade one level.

Q:How to measure the influence of high-temperature performance of the products refractory in the formation of the liquid phase.

Generally how can do high-temperature performance to measure how much liquid may affect hot bending strength rul refractoriness levels of high temperature creep?

Q:Does hardware construction materials contain refractory?

refractory includes one kind of building materials. It is a special material and not commonly used.

Q:Ask some questions about refractories

Application: it is suitable for blast furnace tapping system.

Q:What are the main components of refractory cement?

Refractory cement, also known as aluminate cement, can also be gray. Aluminate cement is often yellow or brown. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. The main mineral of aluminate cement is mono calcium aluminate (CaO · Al2O3, abbreviated CA) and other aluminates, and a small amount of dicalcium silicate (2CaO · SiO2), etc.

Q:What's the refractory material?

Main components of basic refractory are magnesium oxide and calcium oxide, and magnesia brick is commonly used. For the magnesia brick with magnesium oxide content of more than 80%-85%, it has good resistance to basic slag and scum, and it has higher refractoriness than that of the clay brick and silica?brick. It is mainly applied to the open hearth furnace, oxygen-blown converter, electric furnace, non-ferrous metal smelting equipment and some high-temperature devices.

Q:Who knows the fire rating of fire?partition with steel stud?

Partition system made by fire?partition with steel stud and high-quality keel has good fireproofing performance and is non-combustible sheet. Flame burn duration is zero. It does not burn at 800℃, and it is without flame at 1200℃. Its fire resistance rating reaches GB8624-A standard through test, which reaches the highest fireproofing and non-combustible level grade A1. 10MM fire endurance can reach up to 4 hours fire resistance maximum limit. It can absorb a lot of heat during the process of burning and delay the rise of temperature in surrounding environment.

Q:What are the specifications of fireclay bricks?

Specifications of fireclay bricks are shown in the figure;

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 dose the fireproof and thermal insulation material include?

Protective cloth, fireproof cloth, plastic coated cloth, PVC tarpaulin, flame retardant cloth, duct cloth, automobile tarpaulin, PVC protective cloth, the freight yard covered cloth, PVC plastic coated cloth, Industrial Canvas, widely used in automobile tarpaulin, trains covered cloth, ships covered cloth, open-air yard covered cloth, industrial and agricultural covered cloth ; used in glass, timber, fertilizer plants, steel plants, mechanical hardware factories, feed mills, grain storages, container plants, oil refineries plants, packaging plants, paper plants, air conditioning plants, logistics, ore factories, fleet, rail and sea fields, etc.
