Abstract
The invention discloses a coal blending method for controlling coal as fired dilatation of a coke oven with a large-scale wide coking chamber. The method comprises the following steps: carrying out statistics on coal blending dilatation of the existing coke oven with a 6-meter-high coking chamber, and calculating an average value of the coal blending dilation of the 6-meter-high coke oven in accordance with the statistic of the coal blending dilatation of the 6-meter-high coke oven; calculating the coal blending dilatation range of the coke oven with the large-scale wide coking chamber; correspondingly increasing the proportion of varieties of high-dilatation coking coals for coal blending in accordance with the calculated coal blending dilatation range of the coke oven with the large-scale wide coking chamber, determining the obtained coal blending dilatation; if the dilatation is in the control range, determining a coal blending scheme to carry out coal blending coking; and if the dilatation is not in the control range, correspondingly increasing and decreasing the proportion of varieties of high-dilatation coking coals, carrying out coal blending and dilatation detection until the measured value of the coal blending dilatation in the obtained coal blending scheme is in the control range, namely, the coal blending scheme for the coke oven with the large-scale wide coking chamber. The coals blended by the method are subject to reasonable dilation in the large-scale wide coking chamber in the coking process, thus improving the coke quality.
Description
Technical field
The present invention relates to the coke making and coal blending technical field, the blending method of stove coal inferior turgidity difficult to understand (hereinafter referred turgidity) is gone in the reasonable control that particularly is used for large-scale coking chamber coke oven with width.
Background technology
As everyone knows, coking coal is the indispensable resources in field such as metallurgical coke production industry.At present, have now into the stove coking coal and carry out coal blending according to coke quality requirement and existing colliery resource situation.
It has been the general trend of world's coking technology development since the seventies in 20th century that coke oven maximizes.In the coke oven maximization process, the coking chamber height constantly increases on the one hand, and the coking chamber width broadens gradually on the other hand.The increase of coking chamber height has improved the bulk density that has now into the stove coal, improved coke quality, but a large amount of experiments show: it is improper in the control of coking process swelling property that the increase of coking chamber width causes having now into the stove coal, influence coke quality, or increase the high-quality caking coal amount of allocating into, increase the weight of the ERM cost.
Therefore, the blending method that is necessary to provide a kind of control of large-scale coking chamber coke oven with width to go into stove coal turgidity overcomes the defective of prior art.
Summary of the invention
The purpose of this invention is to provide a kind of blending method that large-scale coking chamber coke oven with width is gone into stove coal turgidity of controlling, can be under large-scale coking chamber coke oven with width environment, go in the stove coal coking process swelling property and suitably controlled, improve coke quality, save the high-quality caking coal resource, reduce enterprise's production cost.
To achieve these goals, the invention provides a kind of blending method that large-scale coking chamber coke oven with width is gone into stove coal turgidity of controlling, comprise the steps:
The existing coking chamber height of statistics is 6 meters a coke oven coal blending turgidity, calculates 6m coke oven coal blending turgidity mean value according to 6m coke oven coal blending turgidity statistical value;
