Abstract

The invention provides a bottom blowing system for a converter. The bottom blowing system for the converter comprises an air packet, a regulating valve, a flowmeter, and at least one stop valve, wherein the air packet is used for storing and conveying air; each stop valve is connected in parallel with an air inlet of the air packet through the corresponding switching pipeline; the regulating valve and the flowmeter are connected in series with an air outlet of the air packet through a bottom blowing pipeline; the flowmeter is used for measuring air flow at the air outlet of the air packet; the regulating valve is used for regulating the air flow of the air outlet of the air packet; the system also comprises a controller which is electrically connected with the regulating valve, the flowmeter and each stop valve; and the controller is used for controlling the switch-on and switch-off of each stop valve according to the air supply mode of air which is stored in advance, acquiring the air flow at the air outlet of the air packet, which is measured by the flowmeter, and regulating the regulating valve according to the air flow and the air supply mode. By using the bottom blowing system for the converter, which is provided by the invention, the air flow can be automatically controlled and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to a converter bottom blowing system. Background technique [0002] At present, the gas control method of the bottom blowing pipeline in the steelmaking bottom blowing converter generally adopts the manual control method, that is, the supply and flow control of the gas are realized by manually controlling the valve. Due to the inconvenience of manual control, it cannot be automatically changed with the change of the process, which seriously affects the work efficiency. Moreover, due to the backwardness of the existing manual control method and monitoring means, gas switching cannot be performed accurately and in time, thus causing a great impact on production cost and steelmaking quality. Contents of the invention [0003] Aiming at the problems in the prior art that the converter bottom blowing requires manual control and is inconvenient to operate, the present invention provides a converter bottom blowing system capable of au...
