1. Structure of Metallurgical Coke of NUT coke of 10-30mm  Description:

Coke is made by high temperature metallurgical coke for blast furnace smelting, casting and gasification. Occurring in the process of coking after recovery and purification of coke oven gas is a high calorific value of fuel, is an important industrial raw material in organic synthesis.

On June 3, in most domestic coke market and stable operation, individual regions have appeared downtrend, but declines gradually narrowed.By declines in the commodities market and the downstream steel demand remains sluggish performance, under the influence of the focal company of coke producer prices generally cut 10 to 30 yuan (tons of price, similarly hereinafter), leading to individual regions have with coke prices drop phenomenon, jiao qi said, but most of the region is low and coke coke prices are losing money, so the price will is not strong.After coke enterprises, according to the area where the price reduction, coking plant shipments did not have obvious improvement, the downstream steel receiving still light, lead to coking plant inventory increase slightly.Above all, expected short-term domestic coke market weak downward is given priority to, but not drop too much.

5. FAQ

Our country has experienced from rapid growth to coke production capacity to stabilize rebound, the process of China's coke production in 2010 of 388 million tons, up 9.10% from a year earlier, the proportion of total world production has rose from 20% in 1990 to 61.60% in 2010, is the world's first major producer of coke.


Q: What are the companies that produce coke
Know where you are, there is a good Wuxi, if necessary, can be introduced to you
Q: The chemical composition of coke is m10.m25
Different uses of different coke porosity index requirements, the general requirements of metallurgical coke porosity in the 40 ~ 45%, 35 ~ 40% in coke, coke export demand is about 30%. The crack and porosity of coke and coking coal for the level, which has a direct relationship, such as coal based coke refining cracks, porosity, high strength, low; with coal as the foundation of the coal refining coke crack less, low porosity and high strength. The strength of coke is used to denote the crushing strength and abrasion resistance of the two indicators.
Q: How to distinguish the level of coke. What is metallurgical coke
Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as coke. Other more specific can see here:
Q: Why is coke used in blast furnace steelmaking?Why not use coal?
The reason of coke used in blast furnace steelmaking:Coke is the product after the desulfurization of coal, because the removal of sulfur in coal, coal tar and other harmful substances, no longer in the process of steelmaking, the impact on the quality of steel, the formation of unnecessary ingredients.
Q: What is the difference between the industrial analysis of coke and the industrial analysis of coal samples
There are also ISO and ASTM, I do not know what you want the standard?
Q: What are the ingredients of 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. Coke obtained from high temperature coking for blast furnace smelting, casting and gasification. Coke oven gas produced in the process of coking and recovery is not only a high calorific value of fuel, but also an important industrial raw material for organic synthesis.
Q: The coke is divided into several separate uses
Gasification coke is used for the production of coke gas. The utility model is mainly used in a fixed bed coal gas producer with solid slag discharging, and is used as a gasification raw material to produce CO and H2 as combustible components. The main reaction of gasification process:C+O2 - CO2+408177KJ
Q: Natural gas can replace coke smelting pig iron
No, because the coke in the blast furnace to heat, reducing agent, skeleton and carbon supply four functions
Q: What is the effect of coke moisture on the blast furnace?
The influence of coke moisture on blast furnace can be divided into two parts:
Q: How much coke is needed for a ton of iron
Iron ore in blast furnace, mainly iron and oxygen compound. At high temperature, the carbon monoxide produced in the coke and the carbon dioxide in the injection and the carbon monoxide generated by the carbon capture the oxygen in the iron ore, which is called the reduction. The iron ore is used to produce pig iron by reduction reaction. The gangue in the iron ore, the ash in the coke and the spraying material and the flux of the limestone in the furnace are combined to generate the slag, and the slag is discharged from the taphole and the slag outlet respectively. The gas is derived from the top of the furnace, which is used as industrial gas after dust removal. Modern blast furnace can also use the top of the high pressure, with the export part of the gas power generation.
