Product Description:

1. Structure of Metallurgical Coke of Coke nuts 10-30mm 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.

Chinese coal classification standard of coking coal is divided into two categories:
The first kind of coking coal volatile dry ash-free basis Vdaf = 10% ~ 28%, and the bonding index G > 65, glial layer thickness, y 25 mm or less.This part of the coal coking properties especially good, can separate out qualified blast furnace coke.
Another kind of coking coal volatile dry ash-free basis Vdaf = 20% ~ 28%, the bonding index G = 50 ~ 65, coking properties than the former.Coking coal with medium volatile and better bondability, is typical of coking coal, thermal stability can form good colloid when heated.Separate coking can get large blocks, crack of small, high crushing strength of coke, its wear resistance.But the inflation pressure make coke pushing hard, must match the gas coal, lean coal and so on, to improve the operating conditions and improve the quality of coke.In coking coal in coking coal can act as the skeleton and the effect of shrinkage stress relaxation, thus improve the coke mechanical strength, is the high quality coking raw materials.

On China's coke production distribution, the regional distribution imbalance of coking enterprises, mainly distributed in north China, east China and northeast China.

5. FAQ

From around the world, the coking coal resources are scarce, it is the precious resources must be protected, so has been seldom used coking coal coking alone.

Q:Coke crushing equipment prices, manufacturers offer is how much
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:China's coke iron smelting began in what time?
Han also invented the "fried steel law", that is, the use of pig iron "fried" mature iron or steel of the new process, the product is called steel. At the same time, the rise of "100 steelmaking" technology. The Eastern Han Dynasty (AD 25 ~ 220), when the emperor of the Ming Dynasty, invented the hydraulic blast furnace, that is, "water discharge". The invention of ancient water row in China, about 1100 years earlier than europe. After the Han Dynasty, the method of steel. "Qi Shu Qi, even referred to as" places "big steel", later known as the filling steel, also known as steel group. This is another important achievement of the ancient steelmaking technology in china. According to the "Encyclopedia of" records: Chinese is the earliest use of coal iron country, the Han Dynasty have been tried, song and Yuan dynasties have been popularized. To the Ming Dynasty (AD 1368 ~ 1644) has been able to use coke smelting pig iron.
Q:What is the difference between coke and coking coal
Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% are used in blast furnace, the furnace coke often called metallurgical coke. Metallurgical coke quality standard Chinese formulation (GB/T1996-94) is the blast furnace quality standards.Gasification coke is a kind of coke, which is specially used in the production of gas. It is mainly used in the fixed bed coal gas producer with solid slag discharging. It is used as the raw material to produce CO and H2 gas
Q:What is the difference between coking coal and coke
Coking coal is the raw material for producing cokeCoking coal is produced by carbonization: coal gas (carbon monoxide), coal tar, coke
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: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 the M40% and M25% mean in the analysis of coke?
M40% and M25% represent the breaking strength rate, 40%>25%, which means that the M40% coke is more resistant than M25%
Q:The chemical composition of coke m10.m25 refers to?
M10 refers to the wear resistance of coke, M25 refers to the crushing strength is the mechanical strength. Mainly the cold strength of coke. Coke is also the most important indicator is the hot state, CRI thermal reaction and CSR reaction intensity. In blast furnace production, both cold and thermal strength are important.
Q:What is the phosphorus content in coke
After drying, pyrolysis, melting, bonding, curing, shrinkage and other stages of the final coke, this process is called high temperature coking (high temperature carbonization)
Q:Types of coke and use of coke
China's coking industry has been formed with conventional machine coke oven blast furnace ironmaking production of metallurgical coke, with heat recovery coke oven production machinery foundry and foundry
