Q:What is coke and how is coke classified?

Coke definitionBituminous 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 have Large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough.

Q:What are the requirements for the quality of coke in blast furnace smelting

Coke is a solid product of high temperature carbonization, the main component is carbon, is a crack and irregular pore structure (or porous). The number of cracks has a direct impact on the strength and crushing strength of the coke, the index is generally measured in terms of crack degree (the number of cracks in the unit volume coke). The index of pore structure is mainly expressed by the porosity rate (the percentage of the total volume of coke), which affects the reactivity and strength of coke.

Q:F.C Ash S V.M H2O SizeMore than 85 less than 15 less than 8 less than 0.8 less than 1.5 10-70mm over 90%,I would like to ask, what is the size of the corresponding coke? Metallurgical coke or something else, there is no relevant information about, thank youF.C = 85, Ash = 15, H2O = 8, S = 0.8, V.M = 1.5, Size:10-70mm 90% and above, so clear, like the product, the current price?

Two metallurgical coke: fixed carbon 84.5-85%; calorific value 7000cal/kg; ash < 13.5%; volatile < 1.9%; all 6% "0.7%" water; sulfur;

Q:What is the reasonable ratio of coal to coke

Coal is mainly composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus, and carbon, hydrogen, oxygen and three of the total possession of more than 95% of the quality of the machine, is a very important energy, metallurgy, chemical industry is an important raw material

Q:Used in a restaurant?Dry or dry carbon carbon, coke or coke, and I do not know which word is a word of this sound. The use of coke for iron making. They are more than 1000 yuan price.The main problem is: dry carbon is coke?Toxic smoke, then the chimney can not do? Can I use the blower?

Coke is 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). Coke obtained from high temperature coking for blast furnace smelting, casting and gasification. Coke oven gas produced in the process of coking and recovery is not only a high calorific value of fuel, but also an important industrial raw material for organic synthesis.

Q:The two day of the fire is not wang you have a good way to have any good way. Such online

Coke obtained from high temperature coking for blast furnace smelting, casting and gasification. Coke oven gas produced in the process of coking and recovery is not only a high calorific value of fuel, but also an important industrial raw material for organic synthesis.

Q:Braised meat burning coke, iron black layer, I do not know how to clean, please help answer

Orange to the bottom of the potCut a few slices of orange into the pot boil, stuffy night, second days will be turned over the paste paste, it is easy to clean up.7, the old telephone card, magnetic card washing paste potProblem Description: run out of phone cards, shopping cards, discount cards, VIP cards piled up, although there are people who love this kind of thing, but most people had no interest, so, or use it to do something. When cooking is paste pot, if made of hard coke fouling cleaning shovel, cause scratches with the wooden shovel, and difficult to completely remove the coke fouling. Why not let those old cards reflect the use value?Method of operation: with the card along the edge of the pot, and gradually remove the coke scale clean. Note that when you do not need to force too hard. If the card is made of hard plastic, can also be used to scrape the dirt on the gas stove.

Q:Effect of coal fineness on coke

In coking, the caking property is not good and the coke quality is reduced. Therefore, from the perspective of the uniformity of coal, coal fineness of some good. From the operation point of view, the greater the fineness of coal coal bulk density is lower, the production capacity of coke oven is low, into the coke oven, fine coal powder easily by gas is brought out, and easy blockage of ascending pipe, gas collector, affect the normal production of the coke oven, and the set of tar in the trachea increased, the effect of recovery operation. Therefore, from the production point of view, the fineness of coal should not be too large. Bulk coal in the top of the coke oven, coal crushing fineness of the general control in less than 3mm component in the range of 73~83%. Tamping coking, generally about 90%. In this range, the fineness of pulverized coal can meet the requirements of coke quality and coke oven operation. The small coal crushing will reduce the adhesion and the bulk density of coal, so as to reduce the coke quality.

Q:Coke crushing, coke plant equipment, coke jaw crusher, coke crushing equipment prices, manufacturers offer? How is the output of these equipments?

The index of pore structure is mainly expressed by the porosity rate (the percentage of the total volume of coke), which affects the reactivity and strength of coke. 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 in about 30%.

Q:Can the sulfur content of coke affect the casting process of nodular cast iron at 0.65?

The high sulfur content of nodular cast iron, the most significant impact on the casting is caused by poor balling,
