The invention relates to an external baking process of a coke oven. The external baking process of a coke oven includes adding coal into a coke oven through a feed port, and the coke oven roasts the added coal to obtain coke; adding the coke to a blast furnace as a Iron-making raw materials; the inlet is equipped with a feed valve to control the quality of the coal entering the coke oven. The coke oven is equipped with a temperature measuring device and a temperature adjustment device. The temperature adjustment device is used to control the temperature in the coke oven. Adjustment, the discharge port of the coke oven is equipped with a discharge valve, the coke furnace is equipped with a porosity detection device, and the discharge port is equipped with an ultrasonic detection device; it also includes a central control unit, the central control unit and the feed valve, discharge The valve and the temperature adjustment device are connected separately, and the central control unit can adjust the porosity of the coke according to the actual needs through the influence of the temperature on the porosity of the coke, so as to improve the tapping efficiency of the blast furnace.
Description
technical field [0001] The invention relates to the field of iron and steel production, in particular to a baking process outside a coke oven. Background technique [0002] From the initial iron ore, the steel product is finally obtained through continuous sintering and smelting, rolling, heat treatment and mechanical processing. [0003] In the process of steelmaking, coke furnaces or sintering furnaces, blast furnaces, and converters are usually used to enter secondary smelting, or enter the next steel rolling process. Bituminous coal is heated to 950-1050°C under the condition of isolating the air. After drying, heating Decomposition, melting, bonding, solidification, shrinkage and other stages are finally made into coke. This process is called high-temperature coking (high-temperature dry distillation). Coke obtained from high temperature coking is used for blast furnace smelting, casting and gasification. The recovered and purified coke oven gas produced in the coking...
