Embodiment Construction
[0024] In order to solve the technical problem that it is difficult to accurately measure the performance of coking coal in the prior art, the present invention provides a method for quantitatively evaluating the cost performance of coking coal. The method includes: calculating the performance value of the coking coal according to the formula P1=SCV+CCV; The formula C=P1 / P2 calculates the cost performance of the coking coal; wherein, the P1 is the performance value of the coking coal; the SCV is the first contribution value of the coke strength index; the CCV is the first contribution value of the coke composition index Two contribution values; the C is the cost performance of the coking coal; the P2 is the price of the coking coal.
[0025] The technical solution of the present invention will be further described in detail below with reference to the drawings and specific embodiments.

Abstract
The invention provides a quantitative evaluation method for a coking coal cost performance. The method comprises the following steps: calculating a performance value of coking coal according to a formula P1=SCV+CCV; calculating the cost performance of the coking coal according to a formula C=P1 / P2, wherein P1 is the performance value of the coking coal, the SCV is a first contribution value of a coke intensity index, the CCV is a second contribution value of the coke intensity index, C is the cost performance of the coking coal and P2 is the price of the coking coal; quantitatively evaluating the performance of the coke according to influence on the operation of a blast furnace on indexes of the coking coal generating coke so as to further quantitatively evaluate the corresponding coking coal performance; and finally combining the price of the coking coal to obtain the cost performance of the coking coal so as to objectively and accurately evaluate a coking coal source.
Description
technical field [0001] The invention belongs to the technical field of coal coke, and in particular relates to a method for quantitatively evaluating the cost performance of coking coal. Background technique [0002] Coal is a very complex and heterogeneous mixture. In order to screen cost-effective coking coal resources, in addition to relying on long-term accumulated experience, it is also necessary to establish a quantitative evaluation and screening method for cost-effective coking coal resources. The screening of coking coal resources has become a highly operable process. [0003] Since the price of coking coal is always expressed by a certain value (amount), the key to solve the cost-effective calculation of coking coal resources is the quantitative evaluation of coking coal performance. [0004] For the quantitative evaluation of the performance of various coking coal resources, 14 indicators of coking coal resources are used in the prior art, and a certain influence...
