Product Description:

1. Structure of Metallurgical Coke of Coke lumps15-50MM Description:

Coke is mainly used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting of blast furnace, reducing agent, compound and the function of stock column frame. 

Domestically, a record of steel production has propped up the coking coal demand.Domestic crude steel production record high in March, up 21.9% from a year earlier, to 54.96 million tons."Into the construction and supported by the rising industrial production peak season, coking coal is expected to short-term demand will remain strong.

Blast furnace with Coke instead of charcoal, which laid a foundation for the large-scale of modern blast furnace, is a major milestone in the history of metallurgy.

On China's coke production distribution, the regional distribution imbalance of coking enterprises, mainly distributed in north China, east China and northeast China.

Q:The difference between coke and coal
This is the nature of coal from the formation of coal is coal, and coal deep-processing products
Q:Coke in the steelmaking process in the end is what
Coke is not used for blast furnace ironmakingThe use of blast furnace burden include iron ore (natural ore, sinter and pellets), solvent (limestone or dolomite), and coke, charge from top order batch into the furnace. Coke in the blast furnace ironmaking can be summarized as follows:(1) provide the heat: coke in the coke oven in front of the raceway in the intense combustion, combustion heat generated in the blast furnace smelting process is the main heat source(2) reduction: high temperature gas generated in coke combustion in the raceway, passed to the material in the process of heat rising, the endothermic reaction and coke formation, CO and H2, then CO and iron oxide in iron ore reduction reaction is transformed into metallic iron.
Q:What is the difference between coke and coking coal
Coking coal is a kind of bituminous coal with a high degree of deterioration, and the thermal stability of the resultant colloid is good when the coke is produced separately. The block size of the coke is large, the crack is small and the strength is high
Q:How coke is involved in steelmaking,
Molten iron is produced in a reducing atmosphere of the blast furnace, which is then supplied to the steelmaking plant for steelmaking.
Q:Who knows the proportion of pig iron and coke used in Cupola
Raw material inputs: the main raw material for casting pig iron, scrap steel, manganese, etc.. Under normal circumstances after the melting of ordinary cast iron scrap iron and scrap steel ratio of 9:1 or so, the drying enterprises use pig iron and scrap ratio of about 6:4, according to the requirements of the product. Because pig iron and scrap carbon content is not the same, the higher the carbon content of pig iron is about 4 ~ 4.3, low carbon steel scrap, about 0.8.
Q:Coke is how to make it? What is the use?
The production process has the following procedures:The preparation of coking coal is called coal preparation, which is prepared from various kinds of cleaned coal (or raw coal with low ash content), which is made up of coal, which has the advantages of high accuracy, good particle size, uniform quality and meeting the requirements of coking. Generally include: coal unloading, storage and mixing, mixing, crushing and mixing, and the preparation of coal to coke oven coal storage tower. In cold regions, there should be thawing and freezing equipment. To improve the quality of coke, we must pay enough attention to coal preparation. The coal blending is good, the accuracy of coal blending is improved, the fluctuation of coal quality is minimal, and the chemical composition and the physical mechanical property of the coke are ensured to stabilize the coke quality. Therefore, the coal blending equipment must be accurately according to the given value of coal blending; coal blending tank to be uniform continuous coal. In addition to the impurities in the coal, water can not be too high. The reasonable crushing of coal can effectively improve the mechanical strength of coke. According to the specific situation, the most suitable grinding particle size should be determined.
Q:Coke and coal is one thing
Not the same thing.Coal is often said of coal, including bituminous coal, lignite, anthracite, etc.
Q:How much coal can a kilogram of coal weigh?
This made the better quality of coke and coking coal can be saved!. if it is reality, and generally not numerical said a meal how much coke coking coal, coking coal is mixed because the values of various uncertain coal
Q:Coking coal, coke, coal, steam coal what is the difference?
Coke is used for blast furnace ironmaking and iron ore in the steel furnace to play the role of the heating skeleton to support reducing agent
Q:What's the connection between coking coal and coke
Coke: the quality is hard and the hole is thick, the short hair will be wiped awayCoking coal is a kind of bituminous coal with medium caking property and strong caking property. The title of bituminous coal with high degree of coalification. Main coking coal.
