Abstract

The invention discloses a production process of a forged coal carburant, wherein the process comprises the following processing steps: step S110, mixing of raw materials: mixing 300-mesh powdered petroleum coke and a carbon-containing material, and uniformly mixing the mixed powder with asphalt to obtain a mixed raw material; step S120, pretreatment of the raw materials: adding water into the mixed raw materials in the step S110, and performing rotary disc granulation; step S130, surface treatment: placing the granules in the step S120 in a roller, rotating till the surfaces of the granules are smooth and free of protrusions; step S140, screening; step S150, drying; step S160, graphitization treatment; and S170, packaging. The production process has the beneficial effects that a carburantis subjected to graphitization treatment, so that the structural strength of the carburant can be improved, the breakage of the carburant in the transportation process is reduced, and the carburant has a better particle shape; the purity of the carburant produced by the process is improved, and the thermal and electrical conductivity of the forged coal can be improved after the forged coal is modified.

Description

technical field [0001] The invention relates to the technical field of calcined coal processing, in particular to a production process of a forged coal carburizer. Background technique [0002] Calcined coal is processed by electric furnace or calciner at high temperature. It is an electrode material with low ash, low sulfur, low phosphorus, high calorific value and high compressive strength. In the process of forging coal processing, it is necessary to add a certain amount of carburant to anthracite to change the physical and chemical properties of forging coal, so that it has better structural strength and reduces its specific resistance value. Existing carburizers are often mixed with impurities during production, and new impurities are introduced in the production process of forged coal. Additional processing steps are required to remove impurities, which prolongs the process flow of forged coal production and increases the production cost of forged coal. Contents of t...
