1. Structure of Metallurgical Coke of Coke Strength after Reactivity 62 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.

Our country's metallurgical industry has a long history, is the original fuel charcoal smelting industry, due to the charcoal burning temperature is lower, and short duration of fire and not easy to master hour, therefore, directly affect the level of smelting, to make the steel quality is not guaranteed. Later, people use coal as smelting, coal combustion temperature is higher, and the combustion duration is longer than charcoal, but easily broken after coal is heated in the oven, affect the burden of permeability, and high content of sulfur in coal, directly affect the quality of the cast iron. After a period of practice, it has been found that the coal after dry distillation (i.e., separated flame heating), volatile components may be removed, and the porosity increased, resembling charcoal, fire is better than that of coal, but also can avoid charcoal and coal. This after carbonization of coal is coke.

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?

on the relative density of density, coke, coke porosity, thermal conductivity for the heat capacity of coke, coke, coke, coke ignition temperature, coke thermal expansion coefficient of thermal stress and coke, coke shrinkage rate, coke resistivity permeability, etc.

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)Main type

Metallurgical coke is blast furnace coke, coke, iron alloy and nonferrous metal smelting with coke. As more than 90% of the metallurgical coke for blast furnace ironmaking, so often called the blast furnace coke metallurgical coke.

Foundry coke is dedicated to cupola molten iron. Coke is the main fuel of cupola molten iron. Its role is hot metal melting furnace charge and overheating, support stock column maintain its good air permeability. As a result, coke blocks should have large, low reactivity, low porosity, with sufficient impact crushing strength, ash content and low sulfur content.

In China, "natural coke" used as a fuel. Underground coal seam spontaneous combustion, and can also form natural coke. Natural coke, the grey to dark grey color, more porous, can sometimes show hexagonal prism shape. Compared with artificial coke, weight big, small porosity, density.

Q:The difference between semi coke and coke
Coke strength is poor, poor permeability, high temperature performance is poor, the use of a large risk, easy to cause fluctuations in blast furnace conditions. Prices are relatively cheap. Low temperature coke and high temperature are all coal products.
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: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:How to distinguish the level of coke. What is metallurgical coke
Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as coke. Other more specific can see here:
Q:What is coke and how is coke classified?
Coke definitionBituminous 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 of this process is made of coke, coking high temperature (high temperature carbonization). By high temperature coking coke for blast furnace smelting, casting and gas generated in the process of coking. After the recovery and after the purification of coke oven gas is not only a high calorific value of fuel, and is an important raw material for organic synthesis industry. Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% were used for blast furnace ironmaking blast furnace coke, so often referred to as metallurgical coke is coke. The special cupola molten iron and coke. Coke is the main fuel cupola molten iron. It is melting charge and molten steel overheating, the support column to maintain its good permeability. Therefore, coke should have Large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough.
Q:Braised meat burning coke, iron black layer, I do not know how to clean, please help answer
Orange to the bottom of the potCut a few slices of orange into the pot boil, stuffy night, second days will be turned over the paste paste, it is easy to clean up.7, the old telephone card, magnetic card washing paste potProblem Description: run out of phone cards, shopping cards, discount cards, VIP cards piled up, although there are people who love this kind of thing, but most people had no interest, so, or use it to do something. When cooking is paste pot, if made of hard coke fouling cleaning shovel, cause scratches with the wooden shovel, and difficult to completely remove the coke fouling. Why not let those old cards reflect the use value?Method of operation: with the card along the edge of the pot, and gradually remove the coke scale clean. Note that when you do not need to force too hard. If the card is made of hard plastic, can also be used to scrape the dirt on the gas stove.
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:Who can talk about the coke industry prospects?
With the rapid development of the domestic and international iron and steel industry, the demand for coking products is increasing rapidly, the investment is heating up, and the industry is expanding rapidly. But the coking industry of high resource consumption, production and emissions, especially the emissions of harmful substances, causing serious waste of resources and environmental pollution, brings great pressure to the sustainable development of national economy, which also hindered the rapid development of coking industry.
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,
