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: What is the difference between metallurgical coke and chemical coke
- Metallurgical coke, bituminous coal in the absence of air is heated to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, curing and contraction of the final stage of this process is made of coke, coking high temperature (high temperature carbonization).
- 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: Ca3 (PO4) 2, SiO2, coke and other raw materials for the production of silica gel (SiO2? NH2O), phosphorus, phosphoric acid and CH3OH, the following process raw materials comprehensive utilizationCa3 (PO4) 2, SiO2, coke and other raw materials for the production of silica gel (SiO2? NH2O (P), phosphorus, phosphoric acid and CH3OH, the following process raw materials comprehensive utilization rate is high, less waste(1) in the reaction, which belongs to the replacement reaction is ______[optional: (I), (II) and (III), (IV), (V).(2) chemical reaction equation II under high temperature of ______; solid waste can be used for ______. CaSiO3(3) reaction to be carried out in isolation and oxygen under anhydrous conditions, the reason is ______.(4) CH3OH can be used as a fuel cell fuel in strong acid medium, the electrode reaction type anode for ______.(5) pointed out that the significance of ______. (VI) in this part of the industrial production(6) written by P H3PO4, the reaction of the ______ ______.
- The answer is: (I), (III);(2) under the condition of high temperature, calcium phosphate reacts with carbon and silica to produce calcium silicate, phosphorus and carbon monoxide. The reaction equation is Ca3 (PO4) 2+5C+3SiO2High temperature.?3CaSiO3+2P+5CO =, calcium silicate is silicate, so can produce cement, brick or building materials such as,
- Q: What are the main uses of coke
- Main use of coke:1, is the most important coking products, more than 90% countries most coke used in blast furnace, blast furnace with coke instead of charcoal, laid the foundation for the large-scale modern blast, is an important milepost in the history of metallurgy.
- 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: What are the ingredients of coke
- 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: 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?
- 3) skeleton: smelting process in blast furnace is gas rise and decline occurred in the opposite charge of movement and interaction, the core permeability is the key operation of blast furnace. In the upper column, gas flow distribution of coke layer; in the middle of the column material, the coke from the skeleton effect, support has been melting the iron ore, the normal gas rise; in the lower column, high temperature in the solid massive existing coke and has become liquid hot metal and slag mixed together, become loose skeleton gas rising and falling iron and slag.
- Q: Why in the blast furnace ironmaking with coke instead of charcoal why coke can produce heat to improve the heat of the furnace how to produceWhy in the blast furnace ironmaking with coke instead of charcoal why coke can produce heat to improve the heat of the furnace how to produce
- The reaction of the blast furnace ironmaking is the reduction reaction: the coke produces CO in the furnace, 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!
- Q: How long should it be to store coke in the open air
- The ground is flat, so it is convenient to transport.In addition, if it can be stored indoors, try not to open. For shelter.
- 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!
- Coke strength index is divided into cold strength index and thermal strength indexCold strength index: M40 M25 M10
