Product Description:

Calcined Bauxite for aluminate cement

1.Introduction

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.

Q:The coke is divided into several separate uses
Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke ". Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as coke. The metallurgical coke quality standard (GB/T1996-94) developed in China is the quality standard of blast furnace.
Q:Why does casting coke require phosphorus?
Phosphorus is a kind of harmful element in metal, which reduces the mechanical properties of castings. Under normal circumstances, GB castings of phosphorus content requirements of less than 0.06%, the lower the special requirements
Q:Coke in the steelmaking process in the end is what
3) skeleton: smelting process in blast furnace is gas rise and decline occurred in the opposite charge of movement and interaction, the core permeability is the key operation of blast furnace. In the upper column, gas flow distribution of coke layer; in the middle of the column material, the coke from the skeleton effect, support has been melting the iron ore, the normal gas rise; in the lower column, high temperature in the solid massive existing coke and has become liquid hot metal and slag mixed together, become loose skeleton gas rising and falling iron and slag.
Q:Coke boiler belongs to coal-fired boiler
They produce coke boiler to clean fuel production to reduce emissions as the main content.
Q:What kind of coke is used for steelmaking? The difference between metallurgical coke and foundry coke.
The following indexes: Metallurgical Coke metallurgical coke: fixed carbon, 86%; calorific value 7300cal/kg; ash < 12%; volatile < 1.9%; all 5% "0.6%" water; sulfur; two metallurgical coke: fixed carbon 84.5-85%; calorific value 7000cal/kg; ash < 13.5%; volatile "1.9% full" water; 6%; "three sulfur 0.7%; metallurgical coke: fixed carbon 83-84.5%; calorific value 6500cal/kg; ash < 15%; volatile < 1.9%; all 6%" 1% "water; sulfur;
Q:What is the use of petroleum coke
According to the quality can be divided into two kinds of primary and qualified products. Qualified products are divided into six grades. Used in the manufacture of electrodes, calcium carbide, corundum and so on and used as a filling tank, also used as insulating materials and fuel, etc..
Q:What chemical plant used to coke
Under the condition of isolated air, the bituminous coal is heated to 950-1050 DEG C, and finally, the coke is made by drying, pyrolysis, melting, bonding, solidification and shrinkage
Q:What are the quality indicators of coke
More than 83 of the fixed carbon; sulfur below the volatile content of less than 1.5; ash around 15 e:Mechanism coke: used in metallurgy; steel plantFiddle coke size 8cm-150cm: of molten iron for casting {;} of motor shell, radiator, mechanical counterweightCoal tar: molten iron; used in the casting of motor shell, radiator, mechanical counterweightLarge modified coke: {for ordinary casting; mechanical parts such as rough parts for 2-3.5 tons of furnace type}The shape of coke size 25cm:{is used for ordinary casting and slightly rigid casting products, such as water pump pipe fittings, such as fire fastener
Q:What are the national standards for grade two coke?
All of these are the main indicators, and the water is not the quality evaluation index. The other is the coke reactivity: no more than 35%; after the reaction intensity: not less than 50%
Q:Coke is how to produce, what is its purpose?
Coke is a color of deep gray to black solid, soft; internal structure of porous, and sometimes can be six square column.
