Product Description:

    

1. Structure of Metallurgical Coke of UT  COKE  of  size  is  5 --- 15 mm Description:

Coke is 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.

Coke is mainly used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting of blast furnace, reducing agent, compound and the function of stock column frame. 

Blast furnace with Coke instead of charcoal, which laid a foundation for the large-scale of modern blast furnace, is a major milestone in the history of metallurgy.

5. FAQ

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

1) How to guarantee the quality of the products?

We have established the international advanced quality management system,every link from raw material to final product we have strict quality test;We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

2) What are coke's main physical properties?

The average heat capacity is 0.808 kj/(KGK) (100 ), 1.465 kj/(KGK) (1000 )

Thermal conductivity is 2.64 kj/(MHK) (room temperature), 6.91 kj/(MHK) (900 );

Ignition temperature (air) is 450-650 ℃.

3) 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 the difference between coke and coking coal
Coking coal is a kind of bituminous coal with a high degree of deterioration, and the thermal stability of the resultant colloid is good when the coke is produced separately. The block size of the coke is large, the crack is small and the strength is high
Q:What are the indicators of first grade coke and the two grade coke?
No greater than 12 is not greater than 0.6 not less than 80 not greater than 8 not greater than 1.9
Q:What does the M40% and M25% mean in the analysis of coke?
(1) crushing strength (shatter strength): the ability of a certain particle size coal sample to fall under the condition of free fall.
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:What is the essential difference between coal and coke?
[coal]Coal is a kind of solid combustible mineral which is buried in the underground plants and has been formed by the complex biochemical and physicochemical changes. Coal is a kind of solid combustible organic rock, which is mainly formed by the chemical reaction of the remains of plants.
Q:What are the main uses of coke
The utility model is used for casting blast furnace smelting of non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury, etc..
Q:Distinction and distinction of cokeSoil coke, improved coke, coke machine coke do, what is the difference between
2, gasification coke, is dedicated to the production of coke gas, mainly used for solid slag in the fixed bed gas producer, as a gasification raw material, the production of CO and H2 as a combustible component of the gas:C+O2 - CO2+408177KJCO2+C - 2CO-162142KJC+H2O - CO+H2-118628KJC+2H2O - CO2+2H2-75115KJBecause the process of producing the CO and H2 are endothermic reaction, need heat supplied by the coke combustion, so the heat is gasified char gasification process. The gasification coke required low ash content, high ash fusion point, block proper and uniform.
Q:How coal is turned into coke in the coking chamber
In the furnace in the absence of air through the kiln wall edge ignition hole artificial ignition, coking coal will be stacked in the kiln fire, coking coal self combustion heat by layer coal heating (direct fire heating); a large amount of coal gas from coal combustion and unburned cracking formation hot air flow,
Q:In the coke analysis index, M40% and M25% respectively mean what?
M40% and M25% represent the breaking strength rate, 40%>25%, which means that the M40% coke is more resistant than M25%
Q:What is the use of coke
A definition of English Name: Coke, coke metallurgical coke blast furnace coke, coke, iron alloy coke and non-ferrous metal smelting coke ". Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as coke. Coke is a special and molten iron cupola coke. Coke is the main fuel cupola molten iron. Its role is to melt the burden and make the hot metal overheating, the support column to maintain good ventilation. Therefore, the foundry coke should have large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough.
