Abstract
The utility model relates to a steel ladle air permeable brick maintaining device for a large steel plant, in particular to a device for detecting the air permeability of a steel ladle air permeable brick, which comprises a gas detection control cabinet and a detection control element arranged in the control cabinet; and centralized control is carried out by a Siemens programmable logic controller (PLC) S7-300. A large screen display device is arranged on site and is communication with the S7-300 by a profibus data processing (DP) interface, so that the data in the detection process can be displayed in real time. An industrial control computer is arranged in a control room, is communicated with the S7-300 by an industrial Ethernet and is used for running secondary data acquisition and monitoring programs, thus being convenient for technicists to inquire the historical detection record of the steel ladle air permeable brick at any time and generate a detection report.
Description
Technical field
The utility model relates to a kind of large-scale steelworks air brick of steel ladle maintenance of equipment, a kind of specifically air brick of steel ladle permeability pick-up unit.
Background technology
Along with the continuous development of furnace outer refining technology with popularize, ladle bottom blowing gas control system digital, robotization is used in a large number in iron and steel enterprise.Steel ladle bottom argon blowing is except energy-conservation, evenly outside molten steel composition and the temperature, carries out decisive role smoothly for what guarantee whole production simultaneously.In order to satisfy the accurate control to ladle bottom blowing gas, existing ladle need be by manually air brick being burnt oxygen, cleaning processing, the experience that each time of handling and effect depend on operating personnel fully when rolling off the production line processing.According to the reflection of each operation, still there be obstruction and gas leak phenomenon in various degree in the air brick of steel ladle after the above-mentioned processing of process, can not realize desired bottom blowing stirring technique, has influenced carrying out smoothly of producing.
Summary of the invention
Technical problem to be solved in the utility model is: at the shortcoming of above prior art existence, a kind of air brick of steel ladle permeability pick-up unit is proposed, operating personnel can analyze air brick according to video data and relevant pilot lamp, and whether needs are done surface treatment, reduce workman's workload, and saved activity time.
The technical scheme that the utility model solves above technical matters is:
Air brick of steel ladle permeability pick-up unit comprises gas detection switch board, execute-in-place case, screen display, industrial computer and power distribution cabinet; Power distribution cabinet is connected with gas detection switch board, screen display and industrial computer, and the gas detection switch board is connected with execute-in-place case, screen display and industrial computer; Be equipped with in the gas detection switch board and detect control element and PLC, and is furnished with the ethernet communication module, gas detection switch board outside is connected to nitrogen inlet and nitrogen outlet, nitrogen outlet is connected to the air brick joint, and the PLC internal memory contains the air brick detection under different modes, the application program module of auxiliary clearing function; Execute-in-place case inside is provided with executive component and signal display element, and execute-in-place case panel is provided with touch-screen; Screen display is by umbilical cable and DP cable and PLC communication; Industrial computer is by too Netcom's news module and PLC communication.
Be provided with two covers in the gas detection switch board and independently detected control element, can detect two air bricks simultaneously.PLC is that model is: SIEMENS PLC S7-300.Application program module comprises that various pressure and flow display module and system judge the air brick performance module automatically.Gas feed of gas detection switch board and exit are equipped with filtrator, pressure regulator valve and corresponding manual operating valve.
The utility model has the advantages that: the utility model provides a cover air brick of steel ladle permeability detection system, and operating personnel can analyze air brick according to video data and relevant pilot lamp, and whether needs are done surface treatment.Under the situation that normally ladle cyclic process and each operating personnel operate on request, can gradually reduce the number of times and the time of surperficial oxygen treatments applied, avoided the damage that causes is burnt on the air brick surface, prolonged the serviceable life of air brick.Even need do surface treatment, operating personnel also needn't take blindly oxygen blast mode, but carry out to a certain degree processing according to detection case.In addition, this air brick detection system also provides two-way output, can carry out independent detection to two air bricks simultaneously, has reduced workman's workload, and has saved activity time.
