1. Structure of Metallurgical Coke of Coke Strength after Reactivity 60 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's main physical properties are as follows:
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 ℃;
Low calorific value of dry ash-free basis for 30-32 kj/g;
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
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.
- Q: What is the difference between metallurgical coke and chemical coke
- Chemical coke:Chemical gasification coke, the intensity of the requirements are not strict, but requires a good reaction, high ash melting point; calcium carbide production requirements for coke to improve the fixed carbon contentQuality index of coke
- Q: The chemical composition of coke is m10.m25
- Quality index of cokeThe quality index of coke coke [] is a solid product of high temperature carbonization, the main ingredient is carbon, is the pore structure has a crack and irregular (or pore porous). The crack number directly affects the coke strength and crushing strength, the index of general degree (refer to how to crack crack length unit the volume of coke in the measure.) to measure the pore structure of the main indicators for the porosity (coke pore volume only percentage of the total volume) that it affects the coke reactivity and strength
- 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: Coke boiler belongs to coal-fired boiler
- Coke is commonly used in the smelting industry, such as iron smelting converter, steel blast furnace, ferroalloy electric furnace, etc.
- 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: 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 coke is divided into several separate uses
- Metallurgical coke is 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. The metallurgical coke quality standard (GB/T1996-94) developed in China is the quality standard of blast furnace.
- Q: I work in the coking plant, so there are conditions to get coke and is burning, I would like to use coke barbecue line? Just like charcoal Mutton Cubes Roasted on a Skewer, OK? Understand the answer
- Under the condition of air isolation, the bituminous coal is heated to 950-1050 DEG C, which is finally made into coke by drying, pyrolysis, melting, bonding, solidification and shrinkage.
- Q: How long should it be to store coke in the open air
- So, in addition to avoid rain and direct sunlight, ventilation is.Coal and coke stored in an airless environment, a large degree of risk. The temperature is too high or spontaneous combustion has been easy to stuffy.
- Q: The two day of the fire is not wang you have a good way to have any good way. Such online
- Take the gas stove ignition, and so it was burning 3, and then into the barbecue. Remember to add carbon, open the ventilation cover.
