Bauxite Ore / Raw Bauxite / High Alumina Bauxite

Q: What is the function of refractory material?: Refractory is a basic material in the field of high temperature technology. Generally, the refractory is used as structural material or lining to resist high temperature in various thermal equipment and high temperature container. In the iron and steel industry and metallurgy industry, coke ovens are mainly composed of refractory materials. Various refractories that meet the requirements are essential in blast furnace for ironmaking, hot stove, all kinds of steel-making furnaces, soaking furnace and heating furnace. Not only the die casting for molten steel needs lots of refractory materials, but also the continuous casting needs some high-quality refractory materials. Without high-quality refractory materials, external refining is also not impossible to achieve. Statistics show that the steel industry is the sector that needs the most refractory. Pyrometallurgy and thermal processing of ferrous metal also needs refractories. All high-temperature furnaces or lining in construction materials industry or other high temperature industries that produce silicate products such as glass industry, cement industry, and ceramics industry must be constructed with refractory materials. All kinds of roasting funaces, sintering funaces, heating furnaces, boilers, flues, chimneys and protective layers in chemical, power and machinery manufacturing industry need refractories. In short, when some kind of structures, devices, equipments or vessels are used under high temperature, they all should utilize refractory to resist the high temperature because those materials will deform, soften and fuse or will be eroded, scoured or broken due to the physical, chemical, mechanical effects, which may stop the operation, affect the production, contaminate processed objects and impact the quality of products.

Q: Concrete composition and function of magnesia bond used in refractory: According to the chemical composition and use can be divided into metallurgical magnesia, magnesia brick, magnesia brick, magnesia brick, magnesia calcium brick, magnesia brick and other varieties. Its performance is greatly affected by CaO/SiO2 ratio and impurities. High purity magnesia brick refractoriness under load and thermal shock resistance are better than the general magnesia brick. High refractoriness, has good resistance to alkaline slag and iron slag, is a kind of important senior refractories. Use of magnesia product production by sintering process, sintering temperature is 1500 ~ 1800 DEG C, in addition, you can also add chemical bond, made of brick and unshaped refractory material. Mainly used in open hearth furnace, electric furnace, converter, oxidation non-ferrous metal smelting furnace, cement kiln and alkaline refractory kiln etc..

Q: What type of firebrick does TZ-3 represent?: Z represents a straight brick, T stands for common brick, common straight standard brick, -3 represents the length, and the specification is 230 * 114 * 65 (mm).

Q: Can anyone say something about the curtain wall fire-proof material key sealing point?: Hello. 1. Gaps between the curtain walls and floors of all tier and partitions outer edge should be sealed with non-combustible material or flame retardant materials. Filling material can be rock wool or mineral wool, whose thickness should be not less than 100mm and should meet the designed fire endurance requirements, forming fire and smoke prevention areas between floors and rooms. Fireproof layer should use galvanized steel bearing with thickness of not less than 1. 5mm, and should not use aluminum plate. Gaps between bearing plate and main structure, curtain wall structure and the bearing plate should be sealed by fireproof sealant; fireproof sealant should has fireproof inspection reports granted by statutory testing organizations. 2. When building designs requiring transparent effect of fire compartment and separation, monolithic fire-resistant glass or hollow and laminated fire-resistant glass nade by monolithic fire-resistant glass can be adopted. 3. Windowsills-free curtain walls, incombustible entities skirt wall or fireproof glass wall whose fire endurance is not less tan 1.0 hour and height is not less than 0.8m should be set on the outer edge of each floor. The thickness of reinforced concrete floor or height of the side beams should be counted when calculating the height of the skirt wall. 4. Fire protection layer should not contact directly with the glass curtain wall, and the side towards the glass of fireproof materials should be covered with the decorative material. 5. Glass units of the same curtain wall should not cross two fire?compartments.

Q: What kind of materials can be tested their electrical resistivity in the current refractory industry?: Graphite, Magnesium Oxide, and alumina are all feasible.

Q: What are included in fireproofing materials?: There are many types of fireproof materials, and the following listed below is the main species: All kinds of fire retardant coating such as finishing fire retardant paint, fire retardant coating components, fire-resistant coating for steel structure; all kinds of fire-proof materials such as fire?retardant material and its products, textile, fire?retardant fabric, building materials and products, flooring material and external wall thermal insulation system; all kinds of fireproofing components such as fireproof?panel, fire door, fire resistant window frame, fire resisting shutter, fireproofing glass, elevator landing door,ventilating duct, fire-proof?sealing?material and fire protection smoke exhaust fan. The main indicators to judge fire resistance are: Flame retardency, ignition,production of?toxic?gases, smoke density,heat release and exhaust gas; fire resistance, combustion performance, heat of combustion, fire-resistant performance, high temperature resistance, fire?rating, etc. There are some specific parameters which need to be judged by a professional testing equipment.
