Specifications Met coke

 

Met Coke(metallurgical coke), that is a carbon material resulting from the manufactured purification of multifarious blends of bituminous coal. In its natural form, bituminous coal is soft; its medium-grade composite contains a high occurrence of unstable components. The majority of the unstable components are either reclaimed or recycled.

The coke handled by our couporation is made from superior coking coal of Shanxi province. Provided with the dvantages of low ash, low sulphur and high carbon.Our coke is well sold in European,American,Japanese and South-east Asian markets. Our owned Coke plant are located in Shanxi Province and supplying of you many kinds of coke.

Q:In the coke analysis index, M40% and M25% respectively mean what?
(2) mainly used in: Coal Science and Technology (first level), coal processing and utilization (level two), coal chemistry and coal quality analysis (level three)
Q:The pulverized coal is separated from the air to enhance the heat, in addition to the main coke
Ethylene containing carbon carbon double bonds can react with bromine and bromine, and reaction of bleaching, b.:
Q:What are the requirements for the quality of coke in blast furnace smelting
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%.2, the phosphorus in the coke: iron metallurgical coke coke content should be in the following 0.02 - 0.03%.3, the ash content of coke: Coke Ash on the impact of the blast furnace smelting is very significant. Coke ash increased by 1%, coke consumption increased by 2 - 2.5%, therefore, the reduction of coke ash is very necessary.
Q:What is coke and how is coke classified?
Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% are used in blast furnace, the furnace coke often called metallurgical coke. Metallurgical coke quality standard Chinese formulation (GB/T1996-94) is the blast furnace quality standards.Gasification coke is a kind of coke, which is specially used in the production of gas. It is mainly used in the fixed bed gas producer with solid slag, as the raw material to produce CO and H2 gas:C+O2 - CO2+408177KJCO2+C - 2CO-162142KJC+H2O - CO+H2-118628KJC+2H2O - CO2+2H2-75115KJBecause the process of producing the CO and H2 are endothermic reaction, need heat supplied by the coke combustion, so the heat is gasified char gasification process. The gasification coke required low ash content, high ash fusion point, block degree appropriate and uniform. The general requirements are as follows: >80% fixed carbon ash; 1250 degrees Celsius; volatile 84%, ash
Q:What is the effect of coke moisture on the blast furnace?
2, if the long-term use of water containing high coke and blast furnace gas purification system and dry, it will affect the normal operation of the purification system (filtration pressure increased, serious and even lead to normal filtration, also lead to dust can not be normal unloading etc.); more serious for the blast furnace with net gas said not even a normal discharge (top pressure tank or a pressure higher than indoor clock dozens of kPa
Q:Why does Coke provide heat during ironmaking?
In addition to the reaction of iron and iron oxide will react C+O2=CO2; reaction exothermic;
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:What's the connection between coking coal and coke
Coking coal is divided into two categories, the first category of coking coal dry ash free volatile Vdaf>10% ~ 28%, G>65 bond index, thickness, y = 25mm. This part of the coking coal is particularly good, can separate the qualified blast furnace coke. Another kind of coking coal dry ash based volatile Vdaf>20% ~ 28%, caking index G>50 ~ 65, coking than the former difference. Coking coal is a kind of typical coking coal, which has a good thermal stability
Q:The reaction of the blast furnace ironmaking is the reduction reaction: the coke produces CO in the furnace,
Coke index:The mechanical strength of the mechanical strength of ash sulfur%% volatile(crush strength M40) (abrasion strength M10)No greater than 12 is not greater than 0.6 not less than 80 not greater than 8 not greater than 1.9Two level 12.01-13.50 0.61-0.80 not less than 76 not greater than 9 not greater than 1.9Three level 13.51-15.00 0.81-1.00 not less than 72 not greater than 10 not greater than 1.9
Q:What is the difference between the industrial analysis of coke and the industrial analysis of coal samples
Coke GB/T 1996-2003, volatile coke is the most difficult to do
