Steel ladle bottom argon blowing control system and method

Abstract

The invention discloses a ladle bottom argon blowing control system and a method. The ladle bottom argon blowing control system for an industrial personal computer comprises an industrial personal computer argon blowing control module and an industrial personal computer transmission module, wherein the industrial personal computer argon blowing control module interacts with the industrial personalcomputer transmission module, and the industrial personal computer argon blowing control module comprises an industrial personal computer argon blowing starting module, an information acquisition module, a mathematical model distribution module, an argon blowing mode selection module, a first calculation module and an industrial personal computer argon blowing closing module. The ladle bottom argon blowing system for the industrial personal computer establishes an argon blowing mathematical model for the all-steel type smelting outside a furnace, and different mathematical models can be automatically selected according to different steel types to realize the full-automatic adjustment of argon pressure and flow control in the steel ladle argon blowing process, and meanwhile, two control modes of a remote industrial personal computer control and an on-site terminal control are provided, so that different requirements of technical personnel on a steel ladle bottom argon blowing control are adapted.

Description

Technical field [0001] The invention relates to the technical field of steelmaking, in particular to a control system and method for blowing argon at the bottom of a ladle. Background technique [0002] The argon blowing control system at the bottom of the ladle currently in use usually uses two independent air-permeable bricks to control the argon blowing at the bottom of the ladle. The existing technical solutions for argon blowing control at the bottom of the ladle have the following defects: (1) Uneven distribution of argon flow often occurs. If the flow of argon is too high, it will blow through the molten steel surface and splash, causing the molten steel to be exposed to oxidation and inclusions. If the argon flow is too small, it will not be able to stir quickly, and the purpose of removing the inclusions will not be achieved; (2) There is no operation terminal on site, resulting in high labor intensity for workers on site; (3) The automation of the ladle bottom argon blo...

AI Technical Summary

Problems solved by technology

The existing technical solutions for the control of argon blowing at the bottom of the ladle have the following defects: (1) the phenomenon of uneven flow distribution of argon often occurs, and if the argon flow is too large, it will blow through the liquid surface of molten steel and cause splashing, resulting in exposed oxidation of molten steel, inclusions If the flow rate of argon is too small, it cannot be stirred quickly, and the purpose of removing inclusions cannot be achieved; (2) There is no operation terminal on site, resulting in high labor intensity for workers; (3) The degree of automation of the argon blowing control system at the bottom of the ladle is backward , does not take measures to collect process data for ladle bottom blowing argon control, and does not provide a traceable path for process data for ladle bottom blowing argon control
