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?
(1) power coal(2) coking coal (bituminous coal)(3) coal used in coal chemical industry, which mainly includes gasification coal, coal for low temperature carbonization, hydrogenation of liquefied coal and so on.
Q:The cost of iron ore and coke
Per ton of iron ore 490 yuan / ton, the use of steel per ton coke of 500 kg, coke per ton of 1250 yuan / ton. You can calculate the proportion of these data
Q:What chemical plant used to coke
. 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
Q:How coal is turned into coke in the coking chamber
The kiln chamber wall set to continue burning, and some heat incoming kiln (indirect heating). High temperature gas flow (800 DEG C, is mixed with coal pyrolysis, chemical products into the fabric of unburned.
Q:Relationship between coke M40 and M25
50 kilograms of size greater than 60 mm coke coke samples, in meters Qom in the drum at 50 rpm speed of 100 revolutions (4 minutes), with the aperture is 40 mm (25 mm) sieve screening, measuring more than 40 mm (25 mm) and the weight percentage of the coke, the total weight of the coke drum, denoted as M40 (or M25).
Q:Who knows what the provisions of the coke train sampling country?
Test procedureDetermination of total moistureA, said the samples size less than 13mm with pre dried and weighed for about 500g (referred to 1g), smooth specimen,B, a sample tray is placed on the 170 a 180 C in the drying box, LH removed after cooling, weighing 5min. C, check dryness, each time 10min, until the two consecutive quality difference in LG, calculate the quality of the last time.Determination of moisture content of samplesA, with the weighing bottle drying to constant quality in advance and has quickly called weighing samples size less than 0.2mm uniform mixing of the 1 + 0.05g (referred to 0.0002g), flat on the weighing bottle.B, will be filled with a sample of the bottle to be placed in the 105-110 drying box drying 1H, remove the weighing bottle immediately covered with lid, put into the dryer to cool to room temperature (about 20min), weighing.C, check of dry, insult 15min, until two consecutive poor quality in 0.001g, take the quality of the last calculation, if quality is weight gain first calculated on the basis of.Five, the calculation of test resultsCalculation of total moisture content according to formula (L):
Q:How to remove the bottom of coke steel
After high temperature sintering, and carbonization of things, glued to the pot, often with chemical methods.The most effective way to do this is by hand:Soak in hot water for a few hours (or a day and night).
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:Types of coke and use of coke
The vertical furnace processing of low metamorphic coal production of calcium carbide, ferroalloy, coke, chemical fertilizer production and ultra high power electrode, aerospace and medical high technology and high value-added products such as carbon needle coke the world's most complete and unique characteristics of the Chinese coking industrial system.
