Q:Coke is how to participate in the steel, and the pellets, sintering, a piece of the furnace in the furnace or in other containers: . It is necessary to add coke, pellet, sinter ore, ore and other materials into the blast furnace according to a certain proportion, batch and order

Q:Coking coal, coke, coal, steam coal what is the difference?: Coal is used to generate electricity, which is used to burn coalPower coal is generally only coal

Q:the CO reduces the iron oxide, and the part of CO burns, and the whole process will release a lot of heatCheck information, combined with the knowledge of the professional knowledge, for reference purposes only!: Thermal strength index: CSR CRIM40 M25 is the bigger the better, the smaller the better M10CSR the bigger the better the smaller the better CRISpecific standards to see the specific requirements of steel mills

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 chemical plant used to 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

Q:Various types of coal coke are the main test items: Coal test items which specific indicators of coal test:Generally include coal test indicators include: calorific value of coal (calorific value), sulfur content (sulfur), ash, volatile, fixed carbon, char residue characteristics, total moisture, water analysis and other indicators

Q:What is the concept, relationship and difference between coke and coke? The main difference and contact, thank you: Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke ". Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as 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:What is the use of petroleum coke: Petroleum coke, petroleum coke. Solid residues produced by high temperature coking of residual oil, residual oil or bitumen from petroleum refining.

Q:Coke is how to produce, what is its purpose?: Coke is a color of deep gray to black solid, soft; internal structure of porous, and sometimes can be six square column.

Q:What kind of coke is needed for smelting special steel: What kind of coke smelting special steel need to ask the question itself is wrongThere are many kinds of special steel, different steel with different raw materials, the requirements of the quality of coke is not the sameSteel comes from iron, iron from iron ore and coke, and other additives
