Iron ore species type is various, has found that the iron content of iron ore minerals and about 300 kinds, among the common there are more than 170 kinds.But in the current technical conditions, the main industrial utilization value is magnetic hematite, magnetite, hematite, ilmenite, limonite and siderite, etc.

Q:Why is coke used in blast furnace steelmaking?
The role of coke in blast furnace steelmaking is as follows:(1) providing heat: the coke burns fiercely in the raceway in front of the tuyere of the coke oven, and the heat generated by the combustion is the main heat source in the process of blast furnace smelting.
Q:What kind of coke is used for steelmaking? The difference between metallurgical coke and foundry coke.
Coke is a special and molten iron cupola coke. Coke is the main fuel cupola molten iron. Its role is to melt the burden and make the hot metal overheating, the support column to maintain good ventilation. Therefore, the foundry coke should have large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough
Q:With the number of 1 tons of steel smelting coke
Because it can reduce energy consumption and reduce costs. So in the iron and steel enterprises coke rate decreased as the main goal of public relations, all the staff for the blast furnace coke rate reduction efforts. A few data in Liaoning, the average coke rate of Anshan and Benxi, Anshan Benxi is 330kg/t, is 360kg/t, that is to say a pig needs 330 360kg and coke production 2 saddle of the iron and steel enterprises. Shanghai Baosteel coke for the best in the country, can reach about 280kg/t. Is about 280kg per ton iron coke, the national leading level.
Q:Standard grade two grade coke standard
Evaluation of coke quality1, sulfur content in coke: sulfur is a harmful impurity of iron smelting, which reduce the quality of pig iron. The sulfur content in the pig iron is more than 0.07%. 11% of the sulfur from the blast furnace charge into the furnace comes from the ore, and the other comes from the limestone; the other is from the coke, so the coke is the main source of sulfur in the charge of the 82.5% of the charge. Sulfur content in coke directly affects the production of blast furnace. When the sulfur content in coke is greater than 1.6%, sulfur increased 0.1%, the amount of coke increased 1.8%, limestone amount increased 3.7%, 0.3% increase in amount of ore blast furnace output to reduce the sulfur content under 1.5 - 2.0%. metallurgical coke is not greater than 1%, the use of large and medium-sized metallurgical coke content in blast furnace is less than 0.4 - 0.7%.
Q:The coke is divided into several separate uses
Types of cokeCoke is usually divided by use of metallurgical coke (including blast furnace coke, coke and iron alloy coke etc.), coke and calcium carbide with coke gasification. The utility model is characterized in that the coal is formed by the compression of the coal powder, and a new type of coke, which is processed after carbonization, is called a coke.
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:It was concluded that the following two facts: coke can not be used to restore aluminum ore, but can be used to restore copper and iron ore
K, Ca, Na, C, Mg, Al is not able to use C, CO, H2 and so on to restore the preparation of metal, because these metals are very active, can be used to restore copper and iron ore, indicating that the reduction of strong;
Q:What is the density of coke?
There is also a parameter is also available for your reference: coke porosity of 35% ~ 55%The above parameter is a general range, according to the need to choose to determine.
Q:In the coke analysis index, M40% and M25% respectively mean what?
(1) crushing strength (shatter strength): the ability of a certain particle size coal sample to fall under the condition of free fall.
Q:What are the main uses of coke
A small smelting industry, used to produce calcium carbide, carbon disulfide, phosphorus etc.. In the iron and steel enterprises, coke powder is also used as sintering fuel. Coke can also be used as raw material for the preparation of raw materials for the synthesis of water gas.   4, in order to make the blast furnace operation to achieve better technical and economic indicators, smelting coke (metallurgical coke) must have the appropriate chemical and physical properties, including the smelting process of thermal properties.
