Formed coke, or rammed coke, is a type of synthetic coke produced by using waste coke powder generated during the carbon production process. Its manufacturing method involves combining the following ingredients in specific weight proportions: 300–600 parts of coke powder, 50–100 parts of asphalt, 2–30 parts of aluminum hydroxide, 2–30 parts of kaolin, and other materials. All these ingredients, except for asphalt, are mixed together according to their weight proportions; then the mixture is heated to a temperature at which the asphalt melts into a liquid state. After that, the liquid asphalt is mixed thoroughly, and a molding machine is used to compress the mixture to one-third of its original volume. By processing this waste coke powder into synthetic coke, its utility is increased, and its range of applications expands. This method offers advantages such as high heat generation and excellent molding quality. Compacted coke is coke produced using the compacting coking technique in specialized furnace types. The ramming coking technique is a coking method that, depending on the various uses of coke, involves using a larger amount of coal with high volatility and low caking strength. The prepared coal mixture is compacted in the coal hopper of the coal charging and coke pushing vehicle using a rammer, after which it is pushed from the side of the coke oven into the carbonization chamber for high-temperature dry distillation.
