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.
