Abstract
The present invention relates to the blending method that a kind of two-wire coal blending prevents coke strenth deterioration, including：Main proportioning is designed according to ore deposit point coal characteristics and coke quality control targe, main proportioning is split as by two son proportionings according to the caking property of each coal in main proportioning and coking capacity, the cooperation caking property of coal of two son proportionings is identical or close with coking capacity, followed by crushing, mixes.The present invention is without technological transformation or increase fund input, use devoid of risk, after former two-wire coal blending producer takes this method, coke crushing strength can improve 0.4 2.0%, wear-resistant strength can reduce by 0.2 1.0%, and the stability of coke strenth is improved, it is related with former two-wire mixed coal coal quality difference and coal blending process flow to improve degree.
Description
Technical field
The invention belongs to coal blending field, more particularly to a kind of two-wire coal blending prevents the blending method that coke strenth deteriorates.
Background technology
Domestic coke-oven plant is designed by two-wire mostly with seam, and the less producer of same period adapted coal generally takes one to open one
Standby production of having holidays by turns, and other producer because having to produce at the same time using two-wire adapted coal more.Using being permitted for two-wire coal blending
More producers cause final mixed coal, there are larger coal quality difference, to cause Jiao in both macro and micro aspect because two line coals quality are uneven
There is different degrees of deterioration in charcoal intensity.
The content of the invention
The technical problems to be solved by the invention are to provide the blending method that a kind of two-wire coal blending prevents coke strenth from deteriorating,
This method is without technological transformation or increase fund input, and using devoid of risk, after former two-wire coal blending producer takes this method, coke is anti-crushing strong
Degree can improve 0.4-2.0%, and wear-resistant strength can reduce 0.2-1.0%, and improve the stability of coke strenth, improve degree and original
Two-wire mixed coal coal quality difference is related with coal blending process flow.
A kind of two-wire coal blending of the present invention prevents the blending method that coke strenth deteriorates, including：
Main proportioning is designed according to ore deposit point coal characteristics and coke quality control targe, according to the bonding of each coal in main proportioning
Property and coking capacity main proportioning is split as two son proportionings, the cooperation caking property of coal of two son proportionings is identical with coking capacity or connect
Closely, followed by crushing, mixing；Wherein, the mixed coal mass deviation control range of two son proportionings includes：Volatilization control ±
Within 0.5%, within G values deviation control ± 2.
The coal such as bottle coal, lean coal, mill coal is evenly distributed in two son proportionings in each coal.
The mixed coal mass deviation control range of described two sub- proportionings further includes：Ash content control is ± 1%, sulphur content control
Within 0.5%.After fractionation, the cooperation coal qualities of two son proportionings are closer to better, but mainly to control caking property and coking
Performance is based on.
Described mix is specially to increase mixing machine after pulverizer to mix the mixed coal of two-wire.Increase mixing machine effect
Fruit is optimal, and no mixing machine influences also little.
By weight percentage, the main proportioning is specially：Bottle coal 20%, 1/3 coking coal, 1 7%, 1/3 coking coal 2 8%, low-sulfur
Rich coal 7%, high-sulfur rich coal 8%, coking coal 1 9%, coking coal 2 12%, coking coal 3 9%, coking coal 4 10%, lean coal 10%；
Two sons, which match, is respectively：Bottle coal 10%, 1/3 coking coal 1 7%, low-sulfur rich coal 7%, coking coal 1 9%, coking coal 2
12%, lean coal 5% and bottle coal 10%, 1/3 coking coal 2 8%, high-sulfur rich coal 8%, coking coal 3 9%, coking coal 4 10%, lean coal
5%.
Beneficial effect
(1) present invention uses devoid of risk without technological transformation or increase fund input.
(2) after former single line coal blending producer takes this method, same period adapted coal quantity can be increased, easy to new coal at a low price
Introduce and adapted works, dropping this work for coal blending creates conditions.
(3) after former two-wire coal blending producer takes this method, coke crushing strength can improve 0.4-2.0%, and wear-resistant strength can
0.2-1.0% is reduced, and improves the stability of coke strenth, improves degree and former two-wire mixed coal coal quality difference and coal blending process
Flow is related.
