NUT COKE of Normal Phosphorus
1. Structure of NUT COKE of Normal Phosphorous 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.
Coke is mainly used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting of blast furnace, reducing agent, compound and the function of stock column frame.
Blast furnace with Coke instead of charcoal, which laid a foundation for the large-scale of modern blast furnace, is a major milestone in the history of metallurgy.

- Q: Which heroes know, please give the source of the data.
- Each ton of refining coke can produce 430 cubic meters of gas, half melted combustion, the other half must be recovered with a special device, it can only be discharged directly into the air or "point sky lanterns
- Q: Coke is how to make it? What is the use?
- The production process has the following procedures:The preparation of coking coal is called coal preparation, which is prepared from various kinds of cleaned coal (or raw coal with low ash content), which is made up of coal, which has the advantages of high accuracy, good particle size, uniform quality and meeting the requirements of coking. Generally include: coal unloading, storage and mixing, mixing, crushing and mixing, and the preparation of coal to coke oven coal storage tower. In cold regions, there should be thawing and freezing equipment. To improve the quality of coke, we must pay enough attention to coal preparation. The coal blending is good, the accuracy of coal blending is improved, the fluctuation of coal quality is minimal, and the chemical composition and the physical mechanical property of the coke are ensured to stabilize the coke quality. Therefore, the coal blending equipment must be accurately according to the given value of coal blending; coal blending tank to be uniform continuous coal. In addition to the impurities in the coal, water can not be too high. The reasonable crushing of coal can effectively improve the mechanical strength of coke. According to the specific situation, the most suitable grinding particle size should be determined.

- Visible: the two are called coke crushing strength index, has a certain correlation. Coking coking coal coke, the two general values are relatively large, and vice versa.The specific number of relations, to specific measurement of different manufacturers of coke M40 and M25 values, statistical regression, in order to determine.
- 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.
- 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: Distinction and distinction of cokeSoil coke, improved coke, coke machine coke do, what is the difference between
- The concept of 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). By high temperature coking coke for blast furnace smelting, casting and gas generated in the process of coking. After the recovery and after the purification of coke oven gas is not only a high calorific value of fuel, and is an important raw material for organic synthesis industry. Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% were used for blast furnace ironmaking blast furnace coke, so often referred to as metallurgical coke is coke. The special cupola molten iron and coke. Coke is the main fuel cupola molten iron. It is melting charge and molten steel overheating, the support column to maintain its good permeability. Therefore, coke should be Preparation of large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough.
- Q: How much coke is needed for a ton of iron
- Blast furnace production is continuous. A generation of blast furnace (from start-up to overhaul shutdown of generation) to continuous production of more than ten years. The production, from the top (usually roof is composed by Bell and hopper of modern blast furnace is the valve bell and bell less top) constant load of iron ore, coke, flux, from the lower part of blast furnace tuyere blowing hot air (1000 to 1300 degrees Celsius), sprayed into the oil, coal or natural gas.
