The novel method for judging the influence of the coal blending on the metallurgical coke quality is simple and rapid in problem judgment.
Description
The technical field is as follows:
the invention relates to the technical field of chemical equipment, in particular to a novel method for judging influence of coal blending on metallurgical coke quality.
Background art:
the metallurgical coke coal blending is more and more in variety, and on one hand, the metallurgical coke coal blending has the advantages that: the quality of blended coal can be stabilized by increasing the quantity of single coal, but the single coal used for refining is more, so that the index change of the single coal is very small once the coke quality is abnormal, the influence of which single coal is difficult to judge, the indexes of the single coal need to be checked one by one, the time is long, the data is more, the judgment is inaccurate, and the judgment is very troublesome.
The invention content is as follows:
the invention aims to overcome the defects of the prior art and provides a novel method for judging the influence of coal blending on metallurgical coke quality, which is simple and has quick judgment.
In order to solve the problems existing in the background technology, the invention adopts the following technical scheme: the method comprises the following steps:
1) screening the granularity of the single coal, namely screening the matched single coal with a certain granularity and reserving oversize materials;
2) manufacturing a special test iron box, separating the test iron box into 2 or 4 spaces by using the same iron plate, and separating the test iron box from the top to the bottom according to the quantity of coal;
3) respectively filling the detected coal samples into the separated spaces, and tamping according to requirements to ensure the bulk density of the coal cakes;
4) loading into a test coke oven, setting process parameters, and refining coke;
5) quenching coke, stacking and calibrating names after the coke is smelted and discharged;
6) and (3) comparing the coke quality, namely comparing the quality of the coke of a certain single coal refined at this time with that of the coke refined in normal quality, and comparing the color, the shape, the section texture, the crack state, the size and the state of a non-molten substance and the like.
The invention has the beneficial effects that: the traditional coal charging mode and the test purpose of the test coke oven are changed by using the test coke oven, and the coke is directly refined; the color, morphology and adulterant of the coke are compared.
The specific implementation mode is as follows:
the invention specifically adopts the following implementation modes: the method comprises the following steps:
1) screening the granularity of the single coal, namely screening the matched single coal with a certain granularity and reserving oversize materials;
2) manufacturing a special test iron box, separating the test iron box into 2 or 4 spaces by using the same iron plate, and separating the test iron box from the top to the bottom according to the quantity of coal;
3) respectively filling the detected coal samples into the separated spaces, and tamping according to requirements to ensure the bulk density of the coal cakes;
4) loading into a test coke oven, setting process parameters, and refining coke;
5) quenching coke, stacking and calibrating names after the coke is smelted and discharged;
6) and (3) comparing the coke quality, namely comparing the quality of the coke of a certain single coal refined at this time with that of the coke refined in normal quality, and comparing the color, the shape, the section texture, the crack state, the size and the state of a non-molten substance and the like.
The novel method for judging the influence of the coal for use on the metallurgical coke quality utilizes the test coke oven to change the traditional coal charging mode and the test purpose of the test coke oven and directly refine the coke. The color, morphology and adulterant of the coke are compared.
