Product Description:

1. Structure of Metallurgical Coke of Met Coke 5-25mm 90% min  Description:

Bituminous coal under the condition of the air, heated to 950-950 ℃, after drying, pyrolysis, molten, bonding, solidification and 


contraction phase resulting coke, this process is called high temperature coking (high temperature carbonization).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.

The current coke market resources abundant, steel mills purchase intention is not positive, and steel mills to hong kong-listed late still don't look good.Local high-quality coking coal prices continue to run high at the same time, shanxi main coke plant is controlled in 1200 yuan/ton, generalized the national view, coking enterprises are forced to limit production sharply more, some companies have stopped production, limit production rate in more than 50%, some small coking plant maintain only coke oven heat preservation.

5. FAQ:

We have organized several common questions for our clients,may help you sincerely:

1)Do you have any in stock?

yes,we have.

2)How about your company?

Our company began to export coke when China cancelled 40% of coke export tariffs and quotas on January 1, 2013. We export many kinds of coke, such as CSR60 % and CSR 62% metallurgical coke (met coke), the NUT coke of 20 to 50 mmcoke breeze of 3 to 6 mm, and so on.

Q:What is cokeWhat applications are, what is the fire of Malachite copper
Coke is a kind of reducing agent (C), under the heating conditions and some of the oxidation reduction reaction, can restore some important minerals, such as steel mills, etc..
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:Coke indicators are divided into grades
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).
Q:Who knows the proportion of pig iron and coke used in Cupola
There are doubts: if the scrap ratio is too large to increase the difficulty of processing, product quality can not be guaranteed. The proportion is too high or too low are abnormal.2, auxiliary material input: foundry auxiliary materials mainly coke. Ordinary casting (except dry cylinder) 1 tons ~ ~ 5 tons cupola, each investment of 1 tons of coke, according to the situation of the piece can be from 4.5 tons to 5.5 tons. Ordinary blank (special pieces extra), 5 tons to 10 tons per 1 tons of coke in cupola furnace about 6.5 tons to 7.5 tons of blank (waste products re melted are calculated according to the above method).
Q:What is the difference between coke and coking coal
Coke: a solid fuel, hard, porous, high calorific value coal. High temperature carbonization made for ironmakingTypes of coke:Coke is usually divided by use of metallurgical coke (including blast furnace coke, coke and iron alloy coke, calcium carbide and coke gasification etc.) with coke. The pressurized pulverized coal forming coal, coke carbonization etc. in the new postprocessing process called Formcoke.
Q:Coke in the steelmaking process in the end is what
It is necessary to add coke, pellet, sinter ore, ore and other materials into the blast furnace in a certain proportion, batch and sequence, and then to produce molten iron in the reducing atmosphere of the blast furnaceAfter the hot metal to steel in converter against the general converter, scrap also need to add a certain amount of used to balance the heat. Hot metal and scrap are added to the converter after the oxygen lance for oxygen operation, the oxidation of oxygen to carbon in liquid iron, silicon, manganese, phosphorus, sulfur and some non-metallic inclusions to form steel. Adding lime, dolomite, iron oxide and mine slag and coolant is needed in oxygen at the same time. After the completion of steel smelting in the tapping process according to different requirements with the corresponding iron alloy steel, after also refining process.
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:What does Coke test index M25 mean?
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%. Coke crack degree and the porosity level, and the coking coal has a direct relationship, such as coal based coke refining, crack, high porosity, low strength; with coal as the foundation of the coal refining coke crack less, low porosity and high strength. The strength of coke is usually represented by two indices of crushing strength and abrasion resistance
Q:How to calculate the average particle size of coke
Broken before and after the comparison of granularity, see D50 on the line. There are many kinds of average grain size, and the calculation steps are more complicated.
Q:Various types of coal coke are the main test items
The basic instrument of coal laboratory of these conventional indicators required are: calorimetry, sulfur detection apparatus, muffle furnace (Gao Wenlu), or when the microcomputer controller temperature controller, drying oven (oven), instrument, glial layer measuring instrument, the ash melting point determination of caking index, in addition to auxiliary equipment: crusher, pulverizer, electronic balance, vibration sieve machine, two points etc.. The above is the coal test indicators by Hebi Huanuo coal testing equipment factory to provide, I hope to help you.
