China Calcined Bauxite Ore Metallurgical Grade Bauxite for Cement Industry

Bauxite is a kind of earthy minerals, the main constituent is impurity hydrated alumina. It is white or

off-white, but it will appear tawny or light red because of adding iron.

Bauxite is extremely difficult to melt. It is insoluble in water, but soluble in sulfuric acid and sodium hydroxide solution.

China Calcined Bauxite Ore Metallurgical Grade Bauxite for Cement Industry

Application:

Bauxite is widely apply to refractories, aluminum silicate refractory fiber, precision casting, alumina smelting industry, bauxite cement, etc.

Our Advantages:

1. The bauxite ore is competitive price.

2. High purity.

Q: What is the common inorganic fireproof and thermal inuslation matertial?: inorganic materials of insulation materials 1, inorganic thermal insulation materials are mainly concentrated in the materials that have a certain insulation effect and can achieve level A fireproofing, such as aerogel blanket, glass wool, rock wool, expanded perlite and micro-nano thermal baffle. 2, rock wool production is harmful to human body, workers also do not want to occure the situation under the construction. The cycle of rock wool construction plate is long about 2 years from construction to production. The supply of the domestic wool market also cannot meet the requirements for use. 3, expanded perlite has great weight and high water absorption. 4, the insulation performance of micro-nano insulation panels is 3-5 times that of conventional insulation materials, commonly used in high temperature environment, but is more expensive. 5, aerogel blanket is level A1 inorganic fireproofing building materials, thermal conductivity at room temperature is 0.018W / (K · m), and absolutely waterproofing, its insulation performance is 3-8 times of traditional materials, which can replace the unenvironment-friendly froconventional flexible material with poor insulation properties, such as glass fiber products, asbestos insulation felt and silicate products.

Q: What requirements should refractory materials meet?: The operating temperature of forging furnace is above 1000, which can ensure the normal operation of the furnace, prolong the life of the furnace and save energy. General requirements for refractories are as follows. 1 They should deform at a sufficient temperature without melting. 2, They should have necessary structural strength without softening and deforming. The volume should be stable at high temperature without expansion, contraction or cracking. 4, They can resist erosion of molten metal, slag, gas and other chemicals.

Q: How to detect the acid resistance of refractory? Is there any standard? Thank you: What material it is. There are many kinds of refractory materials, and I basically understand all petrochemical refractory.

Q: Which brand of thermal insulating refractory is good?: The most famous is the dragon, Morgan, Luyang, which are good at making ordinary thermal insulation materials and whose products are cheap but quality. Guangdong ALISON nanometer aerogel is more expensive. The heat conductivity coefficient is 0.018. It can work under 1000℃

Q: Are the specification of fireclay bricks and ordinary clay brick the same?: The standard size of refractory bricks in our country is: 230mm × 114mm × 65mm; ordinary brick: 240 ×115 ×53, building blocks: (it is divided into blind hole and via) 240×390×190, 240×190×190, 240×90×190, 190×190×190, 190×390×190, 190×190×190, 190×90×190, 140×390×190, 140×190×190, 990×200×400, 0×390×190, 90×190×190, 90×90×190. Another is interlocked hollow block : 90×200×400，90×200×245，90×200×200，90×200×100，90×200×290，150×200×275，150×200×200，150×200×100，150×200×290.

Q: What refractories have good mechanical property resistance and heat expansion and cold contraction property?: Explain that where you use it for and what requirements you have. Follow-up: I use it in metallurgical furnaces with the features of strong stirring and acidic residue.

Q: Does hardware construction materials contain refractory?: refractory includes one kind of building materials. It is a special material and not commonly used.

Q: What kind of foundry ingot refractory materials are there? Please be more detailed.: This question is a little bit extensive, because there are too much foundry ingot refractory materials.

Q: what is steel fire door made of ?: 1. fire resistance steel door has steel made door frames, door leaf framework and door panels. if the door leaf is filled with nontoxic fire insulation material, added with fireproof hardware accessories, which consists of a door that is fire resistance. 2. Category 1)safety facilities to prevent underground building from fire expansion and control volatilation. It is usually divided into steel and wooden fire door. 2) Class A fire doors, fire endurance of 1.5 hours; B fire doors, fire endurance of 1.0 hours; Class C fire doors, fire endurance of 0.5 hours. 3) In fact, there are many types of fire doors. For example, there are wooden made fire doors glass fire doors and steel fire doors based on different materials. access control fire doors, entrance fire resistance door, interior fire doors, explosionproof and fireproof door, quick-lock fireproof doors, quick opening door encountered with fire and multi-functional fire doors. 4) Based on the installation location: External fire doors and built-in fire doors. 5) divided by technology: Electronic fire doors.
