Abstract

The invention provides steel and iron smelting material adding equipment applied to the technical field of steel and iron smelting, and further relates to a control method of the steel and iron smelting material adding equipment, and a head roller (12) and a tail roller (14) of a closed conveyor (3) of the steel and iron smelting material adding equipment are arranged to be in an inwards-concave roller shape with the middle being concave. The belt pressing roller (15) is arranged to be in a waist drum roller shape with the middle portion protruding, the head roller (12), the tail roller (14) and the belt pressing roller (15) are respectively installed in the shell (11), a feeding port (111) of the closed conveyor (3) is located below the stock bin (1), and a discharging port (112) of the closed conveyor (3) is located above the weighing hopper (5). According to the steel and iron smelting material adding equipment and the control method thereof, the material feeding precision can be effectively improved, it is guaranteed that the feeding precision is controlled within the set weight range, the requirement of special steel smelting for precise control over steel grade components is met, and the purposes of stabilizing the product quality and saving the cost are achieved.

Description

technical field [0001] The invention belongs to the technical field of iron and steel smelting, and more specifically, relates to an iron and steel smelting material adding equipment, and the invention also relates to a control method of the iron and steel smelting material adding equipment. Background technique [0002] Smelting different steel grades, with different compositions, the demand for alloys and other materials is also different. Some steel grades have a very narrow range of steel composition, and the accuracy requirements for the addition of alloys and other materials are very strict. At present, the steel mill's feeding system uses a large number of vibrating feeders as the main material adding equipment. The technical system used for material addition is: high-level silo→vibrating feeder→weighing hopper→vibrating feeder→feeding point. Although this technical system is relatively smooth in material transportation, the feeding accuracy is very poor, and it can...
