Product Description:

Rotary Kiln Bauxite 85. Homogenized Bauxite 88


1.Structure of Calcined Bauxite 88 Description

The products are produced by corundum and chromium oxide as main materials, formed from casting, being treated under high temperature. Reheating furnace chrome corundum slideway brick. High-speed heat flow erosion and ball dynamic conditions of wearing and tearing, and the low-melting materials under high temperature erosion, infiltration of rotary kiln body, the demanding is rigour for the refractory materials. These materials have high temperature strength, wear resistance, corrosion resistance, long-life time and other excellent properties. 

 

2.Main Features of the Calcined Bauxite 88

Calcined bauxite is one of the principal ore of aluminum. Calcined bauxite contains hydrous aluminum oxides and aluminum

hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areas .Calcined bauxite is obtained by calcining (heating)superior grade bauxite at high temperature (from 85OC to 1600C) .This removes moisture there. By increasing the alumina content,compared to an alumina content of about 57%to 58% in raw bauxite, calcined bauxite has an alumina content of 84%to88%.The heating is carried out in rotary kilns. 

3.Main usage of the Calcined Bauxite 88

1) The bauxite for aluminum industry in defense, aerospace, automotive, electrical, chemical, and daily supplies;

2) Bauxite clinker processed into fine powder and made after the casting mold. Used in military,  aerospace, communications, instrumentation, machinery and medical equipment sector;

Q:what's the fireproof levels of fireproof and thermal inuslation matertial?
1, organic materials: B level material is flammable, B1 level material is flame retardant. 2, inorganic materials: Grade A flame-resistant materials are divided into three classes and two kinds of materials.
Q:What are the use of fire-resistant material and admixture?
I am engaged in admixture and thus familiar. Welcome to exchange!
Q:What things and cement mixed can act as refractory?
This has a lot. I suggest you can check monolithic refractories.
Q:How long is the fire resistant limit for ultra thin fire retardant coating?
The fire resistant limit of ultra-thin fire retardant coating is 1.5 hours, generally fire resisting time for thin fire retardant coatings does not exceed 1.5 hours. If the time exceeds 1.5 hours, thick fire resistive coating should be uesd. There is no detailed stipulation for ultra-thin fire retardant coating, and the thickness of the inside is the fire resistance limit shall reach certain time(at least). If fire resistance limit is 2.5 hours, the thickness shall be 4.9mm. If the fire resistance limit is 2 hours, the thickness is 3.5mm. If fire resistance limit is 1.5 hour, the thickness should be 1.75mm.
Q:which kind of fire bulkhead is better?
I think fire bulkhead is good, fire bulkhead also known as non-combustible fire retardance board, and it's made by various incombustible material after the scientific pressing, and has good flame resisting properties, it's non-combustible time can reach over 3 hours, high mechanical strength,it has characteristics of non-explosive, water and oil resistance, good chemical corrosion resistance and non-toxic.
Q:How many types of fire-resistant material?
1. Acid fire-resistant material refers to one with more than 93% SiO2. It is featured by resistance to the corrosion of acidic slag ad high temperature and easy to react with alkaline molten slag. 2. Alkaline refractory material generally refers to one with magnesium oxide or magnesium oxide and calcium oxide as the main component. It has high refractoriness and strong resistance to basic slag. 3. Silicate aluminum refractory material refers to one with SiO2, Al2O3 as the main component. According to the content of Al2O, it can be divided into three categories: half siliceous (15-30% Al2O3), clay (Al2O3 30 ~ 48%), high aluminum (more than 48% of Al2O3). 4. Fused cast refractory material refers to shaped refractory products made by high temperature melting and casting.
Q:I want to know what is the slim in the refractory bricks
Where are you from, I can introduce to you
Q:What do we mean by saying that a ladle cover knots, elbow knots, blowpipe knots in refractory materials? What is the “knot”?
A less accurate view of the statement is probably the meaning of the “construction of refractory material" , for example, pouring castable can be called “knot”, the pounding of the construction can also be said that, so it is with spraying paint.
Q:What's the difference of fire-resistant material's density, specific gravity and bulk specific gravity?
glass
Q:The performance of refractory material
As for easticity modulus, you can serach for information on the Internet or specialized books.
