1. Structure of Metallurgical Coke of Met coke of CRI 30 Description：

Sulfur content in coke: sulfur is one of the harmful impurities of iron smelting, it lower the quality of cast iron.The sulfur content in pig iron for steel making is more than 0.07% for the trash.By the blast furnace burden into furnace sulfur 11% came from the ore;3.5% from limestone;82.5% from coke, so coke is the main source of sulfur in charge.Coke sulfur content directly affect the blast furnace ironmaking production.When coke sulfur content is greater than 1.6%, sulfur, every 0.1% increase in coke consumption increased by 1.8%, increased by 3.7%, for the amount of limestone ore content of 0.3% by 1.5 - a 0.3% increase in the blast furnace production. The sulfur content of metallurgical coke is not greater than 1%, large and medium blast furnace using the sulphur content in metallurgical coke is less than 0.4-0.7%.

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

5. FAQ

The coke of phosphorus points: metallurgical coke ironmaking use phosphorus content should be below 0.02-0.03%.

Q:Why is coke used in blast furnace steelmaking?Why not use coal?: 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:China's coke iron smelting began in what time?: The ancient iron smelting method in smelting iron block, lower temperature, iron ore solid reduction sponge iron, and iron into play by forging. Smelting iron block, furnace, furnace with ground and shaft 3. The block iron making in our country began in the spring and Autumn period, and in the near future, the pig iron with more than 2% carbon dioxide was refined and used as a casting tool

Q:Coke boiler belongs to coal-fired boiler: In addition, the utility model is characterized in that the utility model is used for heating and catering industry. Generally speaking, coke boiler belongs to coal fired boiler. Reason is that coke is a coal and fat coal for coke production.

Q:What is the difference between metallurgical coke and chemical coke: The chemical composition of coke including fixed carbon, ash, sulfur, volatile matter and moisture. Except moisture, other ingredients in dry coke, is an important raw material of cupola smelting, casting of the components of specific inspection requirements.

Q:What is the difference between coking plant and coke plant: Ha-ha，Coking plant, is a chemical industry, a variety of products,,Such as the production of coal tar, gas, coke and other chemical raw materials

Q:What kind of coke is needed for smelting special steel: It is necessary to add coke, pellet, sinter ore, ore and other materials into the blast furnace in a certain proportion, batch and sequence, and then to produce molten iron in the reducing atmosphere of the blast furnace

Q:Ask: coking coke tower tower and what is the relationship?If you can give a working principle to explain what is better!Coking tower in oil coking plant: Coking plant coal tower, primary cooling tower, cooling tower, etc.. The coal tower is used to store coal for coke oven. The cooling tower is used to cool the gas and cooling tower cooling water.

Q:How many degrees of coke ignition temperature can ignite coke: The average specific heat capacity is 0.808kj/ (KGK) (100 DEG C), 1.465kj/ (KGK) (1000 DEG C);The thermal conductivity is 2.64kj/ (MHK) (room temperature), 6.91kg/ (MHK) (900 DEG C);Ignition temperature (450-650) in air;

Q:Coke in the whole process of steelmaking in the end is what to do, just to provide heat or carbon and other substances into steel or iron?In the study of coal classification inside, one is divided into coking coal, coking coal and coke as main, and then you see is steel or iron coke must material. What is not clear. In the end, out of coal mining is mainly used to burn energy extraction, or said that coal like oil can be converted into other products, which is a coke can convert?: It is necessary to add coke, pellet, sinter ore, ore and other materials into the blast furnace in a certain proportion, batch and sequence, and then to produce molten iron in the reducing atmosphere of the blast furnaceAfter the hot metal to steel in converter against the general converter, scrap also need to add a certain amount of used to balance the heat. Hot metal and scrap are added to the converter after the oxygen lance for oxygen operation, the oxidation of oxygen to carbon in liquid iron, silicon, manganese, phosphorus, sulfur and some non-metallic inclusions to form steel. Adding lime, dolomite, iron oxide and mine slag and coolant is needed in oxygen at the same time. After the completion of steel smelting in the tapping process according to different requirements with the corresponding iron alloy steel, after also refining process.

Q:What is the essential difference between coal and coke?: [coal]Coal is a kind of solid combustible mineral which is buried in the underground plants and has been formed by the complex biochemical and physicochemical changes. Coal is a kind of solid combustible organic rock, which is mainly formed by the chemical reaction of the remains of plants.
