Everyone is welcome to discuss how to improve the thermal properties of coke
Thread Content
Recently, due to the company’s requirement to increase production, the coking time in coke ovens has been reduced. However, the requirements regarding thermal properties remain unchanged, and the quality of the coal has not improved either. Please discuss how to ensure the hot and cold properties of coke under these circumstances. We experimented with several methods on our own, but the results were not very significant: 1: Foam quenching; 2: Adding modifiers to the coal; 3: Adding oxides to the coal. What other methods do everyone have for communicating?
The intensity of heat and cold is primarily influenced by the coal quality, as well as by factors such as quenching conditions, the porosity of coke, and the composition of coke ash. Measures such as low-water quenching to improve quenching conditions, graphite deposition to enhance coke porosity, and boron-based additives to modify the ash composition can be helpful. In addition, the fineness of the coal blend also has an impact.
