At the same time coke cold strength from the production coal blending proposal was compared with coke cold strength from anthracite blending proposal, the result shows: when the blending ratio of anthracite was 3%~5% and the size of anthracite is ≤ 1mm, coke cold strength was increased by about 2%.
This process consists of the determination of“J method”,the principlc both coal and coke,Jb-v_(def) ̄2 米 type mixing coal scheme and the optimizing ratio of mixture,etc,so. that can be acheived with economical condition and LM_(40)≤1.5.L_M_(10)≤1.0 can be ensured.
During making up mixing coal plan V-g1 could do as main parameter to comprehensively equalize the influence of parameters of G,Y,TI(TR ), etc,on strength.
Through the test analysis carried out for the reactivity,strength after reaction of Meishan coke and quality index of coal blend,the results show that coke ash content,volatile matter and maximum thickness value Y of colloidal matter layer of coal blend are the important factors influencing the thermal property of coke,while the cold strengths M40 and M10 of coke have no obvious relationship with the thermal property of coke.
As a first step to an on-line analysis system for process control in a coal blending plant we have developed a facility using a Cf-252 neutron source with an actual strength of 1 mg.
