Abstract

The invention relates to a monitoring device, and particularly relates to a device for monitoring the water leakage of an oxygen lance for a vacuum refining furnace. The device comprises a PLC controller, a pipeline and an oxygen lance body, and the device is characterized in that a pressure sensor, a temperature sensor and a flow transmitter are sequentially arranged on the pipeline between a water inlet and water outlet of the oxygen lance body, and the pressure sensor, the temperature sensor and the flow transmitter are all connected with the PLC controller. The device disclosed by the invention is unique in structure, and used for acquiring and monitoring three parameters of the oxygen lance in a steel ladle when the vacuum refining furnace carries out smelting in the process of casting, thereby improving the security and reliability of the vacuum refining furnace.

Description

A kind of device of monitoring vacuum refining furnace oxygen rifle and leaking
Technical field
The present invention relates to a kind of monitoring device, especially relate to a kind of device of monitoring vacuum refining furnace oxygen rifle and leaking.
Background technology
Smelt the vital role that oxygen blast plays molten steel component adjustment in fusion process, the monitoring of smelting oxygen rifle is the important step of vacuum refining furnace smelting equipment safety.In smelting, oxygen rifle will be moved up and down by machinery in airtight space, and carry out oxygen blast to the molten steel of 1600 DEG C in ladle, oxygen pressure reaches 0.8mpa.In this process, oxygen rifle is in vacuum-tight retort, operator's visual inspection less than, entirely carry out oxygen blast observation by rule of thumb.Oxygen rifle body is lowered the temperature to it by following the water coolant gone bad, if oxygen rifle burns out leaks, and operative employee can only be observed by the vision slit of ladle, or is judged by spent air temperture, vacuum tightness height, not only affects production efficiency, also affects steel quality simultaneously.Due to cannot Timeliness coverage oxygen rifle water leakage fault, a large amount of water also may be caused to enter molten steel thus cause smelting accident.
Also do not overcome the device of above-mentioned defect at present.
Summary of the invention
The object of the invention is the defect overcoming prior art, the collection that is unique, oxygen-blowing gun three kinds of parameters in ladle when smelting for vacuum refining furnace in castingprocesses of a kind of structure, monitoring are provided, improve the reliability of vacuum refining furnace, a kind of of security monitor the device that vacuum refining furnace oxygen rifle leaks.
The present invention realizes in the following way:
A kind of device of monitoring vacuum refining furnace oxygen rifle and leaking, it comprises PLC, pipeline and oxygen rifle body, it is characterized in that: setting pressure sensor, temperature sensor and flow transmitter successively on the water-in of described oxygen rifle body and the pipeline of water outlet, described pressure transmitter, temperature sensor and flow transmitter are all connected with described PLC;
A magnetic valve is equipped with in the front end of the described pressure transmitter on the pipeline of described oxygen rifle body water-in section, and this magnetic valve is connected with described PLC;
Installing described pressure transmitter, temperature sensor and flow transmitter pipeline place apart from the distance of described oxygen rifle body is 2 ~ 2.5m.
The present invention has following effect:
1) structure collection that is unique, oxygen-blowing gun three kinds of parameters in ladle when smelting for vacuum refining furnace in castingprocesses, monitoring: device provided by the invention, it comprises PLC, pipeline and oxygen rifle body, it is characterized in that: setting pressure sensor, temperature sensor and flow transmitter successively on the water-in of described oxygen rifle body and the pipeline of water outlet, described pressure transmitter, temperature sensor and flow transmitter are all connected with described PLC.
2) present invention utilizes PLC control technology to monitor in real time the import and export of vacuum refining furnace oxygen rifle water temperature, pressure and flow parameter, improve the safe reliability of oxygen rifle when smelting.Meanwhile, the smelting accident because oxygen rifle water leakage fault may cause effectively is prevented, support equipment safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
A kind of device of monitoring vacuum refining furnace oxygen rifle and leaking, it comprises PLC 1, pipeline 6 and oxygen rifle body 7, as shown in Figure 1: setting pressure sensor 2, temperature sensor 3 and flow transmitter 4 successively on the water-in of described oxygen rifle body 7 and the pipeline 6 of water outlet, described pressure transmitter 2, temperature sensor 3 and flow transmitter 4 are all connected with described PLC 1.
A magnetic valve 5 is equipped with in the front end of the described pressure transmitter 3 on the pipeline of described oxygen rifle body 7 water-in section, and this magnetic valve 5 is connected with described PLC.
Installing described pressure transmitter 2, temperature sensor 3 is 2 ~ 2.5m with flow transmitter 4 pipeline place apart from the distance of described oxygen rifle body 7.
The left side of oxygen rifle body 7 is water-in, right side is water outlet, and top is inlet mouth.
First, be 0.70MPa-0.8MPa according to the normal hydraulic pressure of processing requirement setting oxygen rifle, flow is 20m3/h ~ 22 m3/h, inlet temperature 25 DEG C ~ 35 DEG C, temperature out 45 DEG C ~ 55 DEG C.Automatically open the magnetic valve on oxygen gun barrel road after PLC receiving process parameter, simultaneously the pressure transmitter at two ends, temperature sensor and flow transmitter are collected 3 kinds of parameters and are fed back to PLC.
The parameter that pressure transmitter, temperature sensor and flow transmitter feed back to by PLC in real time and processing requirement setup parameter contrast.
1) when the parameters such as the pressure fed back to, flow, temperature are at setting range, oxygen rifle normally works;
2) if the parameter fed back to wherein 1 exceed parameter setting scope, then oxygen rifle may leak.Now, PLC can send warning automatically, and magnetic valve is cut off rapidly simultaneously, and oxygen gun barrel road stops supplying water.
