Abstract

The invention relates to a steelmaking alloy and slag material automatic discharging and weighing putting device and method, and belongs to the technical field of steelmaking metallurgy. According tothe technical scheme, a trolley track (6) is arranged in the middle of a steel structure bracket (7), a weighing feeding trolley (2) is arranged on the trolley track, a weighing device is arranged onthe weighing feeding trolley, and the weighing feeding trolley is provided with a trolley vibrating feeding machine (1) in a matched manner; and the upper part of the steel structure bracket is provided with a plurality of material bins (4), a material bin vibrating feeding machine (3) is arranged below each material bin, the material bin vibrating feeding machines are arranged through suspensionmechanisms (5), the weighing feeding trolley is provided with a discharging pipe, the trolley vibrating feeding machine (1) and the discharging pipe are arranged together, and discharging pipes of themultiple material bin vibrating feeding machines (3) are jointly provided with the weighing feeding trolley in a matched manner. The steelmaking alloy and slag material automatic discharging and weighing putting device and method have the advantages and effects that feeding of a refining furnace can be efficiently and accurately achieved during refining, the precise control ability of a steel component is improved, the labor intensity is reduced, and the product quality is improved.

Description

technical field [0001] The invention relates to a device and method for automatically unloading, weighing, and feeding steelmaking alloys and slag materials, and belongs to the technical field of steelmaking metallurgy. Background technique [0002] With the continuous increase of domestic high-end special steel market demand, users have also put forward higher and higher requirements for product performance and internal quality. The refining furnace is an important production process of the converter steelmaking plant. After the converter is smelted and before the molten steel enters the continuous casting machine, it must pass through the refining furnace to control the temperature of the molten steel and adjust the composition of the molten steel. The composition of the molten steel is adjusted according to the needs of the steel type by adding It is realized by different types and weights of charge. The refining furnace charging system is used to accurately add differen...

Problems solved by technology

At the same time, the requirements for standardization, high efficiency, on-site 6S management and environmental protection of on-site operations are getting higher and higher, and the method of bagging and manual addition of alloy and slag can no longer adapt to the current high-efficiency, standardization and on-site operation environment. control requirements

Manual feeding has the following disadvantages: (1) manual operation, high labor intensity for post workers, poor site environment, inaccurate dosage, and large smoke and dust when feeding

(2) The alloy and slag of the refining furnace need to be packaged in small packages before use. In addition to the inability to achieve precise control, monitoring and recording of the amount of materials added, the materials are often damaged to varying degrees during transportation, which brings great harm to the use of the refining furnace. It is inconvenient to come, and the weight of the subpackage cannot be guaranteed

To this end, it is necessary to invent an automatic and standardized feeding system, an automatic weighing and feeding device for alloy and slag, which can solve the problems of high labor intensity for operators, poor on-site 6S, and quality traceability caused by manual addition of alloy and slag in the current refining furnace. gender issues
