Q:After the long-term use of non stick pan, oil stains can not be effectively removed, over a long period of time in the non stick coating on the formation of a layer of coke, the effect of losing non stick. As a result of this layer of coke is relatively dense and smooth, scouring cloth has been ineffective, steel ball can not be used to damage the coating, what chemical or physical methods to remove this layer of coke?

Four, wash the metal wire ball friction force discoloration, and always use water to clean out the dirt.So that the whole place to restore the original black dye can be done.Water sandpaper rubbing can of course, but in the end to more than 1000 mesh water sandpapering. Another 100 clean cloth polishing line. The coke on the stove can only be removed by hand.Finally, wash the rice cooker, stove, as well as your tired hands, thoroughly washed several times. Here, everything is back to normal, as if nothing had happened.

Q:Ask: coking coke tower tower and what is the relationship?If you can give a working principle to explain what is better!Coking tower in oil coking plant

Coking plant production capacity on the exclusion of the tower is also on the two: first, the coal tower; the two is coke bin;

Q:How long should it be to store coke in the open air

And the most important thing is to avoid the sun. Coal and coke, like the sun, the temperature inside the stack is very high. So try to cool down.

Q:What is the amount of waste gas produced by a ton of coke burning

Process for producing coke, coke oven gas and coking chemical products by thermal decomposition and coking.

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 phosphorus content in 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.

Q:What is the reasonable ratio of coal to coke

According to the proportion of each unit type, different operation, different existing coal and different coke quality requirements are different and so on, can be said to suggest that the landlord can look at the altar of the myriads of changes, in some aspects of the coal blending, grasp some general principles, and then develop the proportion according to the actual situation.

Q:What are the uses of these early industrial iron and steel? Any difference?What kind of carbon do we eat in the middle of a long strip of carbon?

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:How to determine the maturity of coke or not?

The degree of fragmentation of coke: refers to the different levels of coke accounted for the percentage of total coke production. The particle size of coke is very important in blast furnace smelting. The coke block is uniform, the gap is large, the resistance is small, and the furnace condition runs well.Breaking strength of metallurgical coke (M40 drum index)The breaking strength of metallurgical coke is an index to reflect the breaking resistance of coke.Wear resistance of metallurgical coke (M10 drum index)The wear resistance of metallurgical coke is an index to reflect the wear resistance of coke.

Q:8 points will be isolated from the air to enhance the heat of coal, in addition to the main coke, but also the material listed in the following table: No.

Carbon containing ammonia, which belongs to the inorganic carbon monoxide; although contain carbon and inorganic nature but similar, belonging to the inorganic material, so the answer is: the 7;
