Coke coking process. 1. Coal washing: The raw coal is cleaned before coking, in order to reduce the ash contained in the coal and remove other residues. 2. Coal blending: It is a process in which coal of different types of gas, fertilizer, coke and lean is prepared according to a certain proportion, and is naturally loaded into the coke oven ...

The accurate prediction of coke quality is important for the selection and valuation of metallurgical coals. Whilst many prediction models exist, they tend to perform poorly for coals beyond which the model was developed. Further, these models general fail to directly account for physical interactions occurring between the blend components, through the assumption that …

Occasional deep-seated flowslides in coking coal stockpiles at the North Queensland port of Hay Point are described. The flowslides result from particularly loose placement of the light, cohesionless material, and saturation of the lower levels of the stockpile due to rainfall infiltration and initial moisture at placement.

Coke is an important raw material in the steel industry, and its quality directly influences the smelting of iron and steel. To improve coal quality and reduce coal blending costs, we need to predict the coke quality and optimize the coal blending scheme. In this paper, we propose a modeling and optimization method based on the characteristics of the coal …

Coal blending is the process of mixing coals after coal has been mined to achieve quality attributes that are desirable for the coal's intended application (e.g. steam generation, coking). The quality attributes that are most important in blending will differ from one mine site to another and also depend on how the coal seams vary in quality and their final intended use.
