Product Description:


1. Structure of Metallurgical Coke of Coke Breeze of 3-6mm  Description:

Calcium carbide with coke is in the production of calcium carbide electric arc furnace coke used as conductive and heating element.Calcium carbide with coke in electric arc furnace, the electric arc heat and heat resistance of high temperature (1800-2200 ℃), and lime complex reaction, generate molten state of calcium carbide (carbide).

Focus carbon ferrosilicon alloy production requirement is: high fixed carbon content, low ash, ash harmful substances in the 3 oxidation 2 aluminium and less content of phosphorus pentoxide, etc, coke reactivity is good, coke resistivity especially resistivity at high temperature, volatile lower, with the proper strength and the degree of blocks of food, water and less stable.

Q:How much coke can a ton of coal
The key depends on volatile coking coal quality good volatile low words should now 1.3-1.4 tons of coking coal out of a ton of coke
Q:How many degrees of coke ignition temperature can ignite coke
Ignition temperature (450-650) in air;The main physical properties of coke are as follows:True density is 1.8-1.95g/cm3;Apparent density of 0.88-1.08g/ cm3;
Q:How long should it be to store coke in the open air
So, in addition to avoid rain and direct sunlight, ventilation is.Coal and coke stored in an airless environment, a large degree of risk. The temperature is too high or spontaneous combustion has been easy to stuffy.
Q:What is the effect of coke moisture on the blast furnace?
The influence of coke moisture on blast furnace can be divided into two parts:
Q:Why does Coke provide heat during ironmaking?
Generate CO2;Of course, high temperature will produce CO, but not many;Please ask questions
Q:The total amount of heat released by the fully burnt 200g coke is 60% by the mass of 10kg water absorption [q coke =3.0 * 107J/kg, C water =4.2 * 103J/ (kg = C)
Dry water temperatures:Delta t=Q ceilingC water m water=3.6 x 106J4.2 x 103J/ (kg * c) * 10kgC = 85.7,At the end of a water temperature t=t0+ t=20 C +85.7 =105.7 oc,
Q:Coke crushing equipment prices, manufacturers offer is how much
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:What is the essential difference between coal and coke?
Coke]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 is made, the process is called high temperature coking (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.Coke is mainly used in blast furnace ironmaking and smelting of non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury and so on. The use of coke instead of charcoal in the blast furnace has laid the foundation for the large-scale development of modern blast furnaces and is a major milestone in the history of metallurgy. In order to achieve better technical and economic indexes of blast furnace operation, the coke (metallurgical coke) must have proper chemical and physical properties. In addition to a large number of coke used in iron smelting and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, the quality requirements are different. Such as foundry coke, generally require large size, low porosity, high fixed carbon and low sulfur; chemical gasification, strict requirements for strength, but requires good response, high ash melting point; calcium carbide and coke production requirements to improve the fixed carbon content.
Q:Coke coal charcoal are used for what
Charcoal:1 metallurgical industryIn the past, the charcoal was used to smelt iron ore, and the pig iron was melted by charcoal and coke. The structure and mechanical properties were not the same even if the chemical composition was the same. The charcoal smelting pig iron generally has the fine grain structure, the casting is compact, does not have the crack the characteristic, the pig iron with the charcoal production contains the impurity is few, is suitable for the production high quality steel. Due to the reduction of charcoal, so in the metallurgical industry can be used to restore ore smelting metal.In the non-ferrous metal production, charcoal used for surface flux, non-ferrous metal melting, the surface flux in the molten metal surface protective layer, so that the separation of metals and gases, can reduce the loss of molten metal splash, and can reduce the melting material in gas saturation.A large amount of charcoal is also used to produce crystalline silicon, silicon used charcoal ash production should not contain too much carbon and head.
Q:The difference between coke and coal
Coal is known as the black gold, the food industry, which is one of the main sources of energy used in the human world since eighteenth Century...
