Abstract
The utility model discloses a ladle bottom argon-blowing automatic adjusting device. The ladle bottom argon-blowing automatic adjusting device comprises a control system and an argon source; the argon source is connected with two pipelines; one pipeline is a refined ladle argon-blowing pipeline which is connected with a depressurization valve, a gas quality-flow controller, a check valve, a servo pilot-operated two-position two-way electromagnetic valve and a pressure transmitter sequentially; the other pipeline is an air-in-pipeline exhaust pipeline which is connected with the refined ladle argon-blowing pipeline in parallel; the air-in-pipeline exhaust pipeline is connected with the servo pilot-operated two-position two-way electromagnetic valve and the check valve sequentially; and the two pipelines are connected with the control system. The ladle bottom argon-blowing automatic adjusting device has the characteristics of simpleness and convenience for operation, unnecessity of manual guard in the smelting process, rapidness for signal feedback and argon flow adjustment, strong stability and capability of automatically selecting different mathematic models to control the argon blowing process according to different steel types.
Description
Technical field
The utility model relates to a kind of steel ladle bottom argon blowing automatic-adjusting device.
Background technology
The ladle bottom blowing ar system is to realize that molten steel stirs, makes liquid steel temperature and chemical ingredients evenly, effectively to remove gas and the non-metallic inclusion in the molten steel, the key device of raising molten steel quality.
At present, domestic design to the steel ladle bottom argon blowing automatic-adjusting device, each big dedusting producer attempts having adopted various modes.Like manual mode,, manually control argon pressure and flow through the mode of workman's field observation molten steel with bottled argon gas, manual modulation valve.
Now; The Argon device is used the semiautomatic controls mode always; Through controlling elementss such as reducing valve, SV, pneumatic diaphragm control valves, by workman's field observation feedback signal to the watch-keeping cubicle, industry control hands-operation control corresponding valve regulated argon pressure and flow in the watch-keeping cubicle.Have significant drawback: the adjusting of argon pressure and flow be unable to do without artificial the intervention, and the stability of operation can not get guaranteeing that the time of response is slow, also increases workman's labor capacity simultaneously.
Need this moment a kind of easy and simple to handle, and it is on duty to need not manual work in the smelting process, can select different mathematics to carry out the Argon process control automatically according to different steel grades, the steel ladle bottom argon blowing automatic-adjusting device that signal feedback is fast, argon flow amount is regulated rapidly, stability is strong.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art; A kind of steel ladle bottom argon blowing automatic-adjusting device is provided; It is easy and simple to handle; It is on duty to need not manual work in the smelting process, can select different mathematics to carry out the Argon process control automatically according to different steel grades, and signal feedback is fast, argon flow amount is regulated rapid, by force stable.
For addressing the above problem, the utility model adopts following technical scheme:
The utility model provides a kind of steel ladle bottom argon blowing automatic-adjusting device; Said device comprises a system and argon gas source; Said argon gas source is connected with the two-way pipeline; One road pipeline is a refining bag Argon pipeline, is connected with reducing valve, gas mass flow amount controller, vacuum breaker, pilot servo formula 2/2-way SV and pressure unit in turn; Another road pipeline is connected in parallel on the refining bag Argon pipeline for getting rid of airline in the pipeline, is connected with pilot servo formula 2/2-way SV and vacuum breaker in turn, two-way pipeline connection control system.
The utility model is easy and simple to handle, and it is on duty to need not manual work in the smelting process, can select different mathematics to carry out the Argon process control automatically according to different steel grades; The argon flow amount precision is high; Operation and maintenance cost is low, effectively reduces the consumption of argon gas, has shortened tap to tap time.
Description of drawings
Fig. 1 is the utility model principle schematic.
Embodiment
As shown in Figure 1; The utility model provides a kind of steel ladle bottom argon blowing automatic-adjusting device; Said device comprises a system (not shown) and argon gas source 1; Said argon gas source is connected with the two-way pipeline, and one road pipeline is a refining bag Argon pipeline 10, is connected with reducing valve 11, gas mass flow amount controller 12, vacuum breaker 13, pilot servo formula 2/2-way SV 14 and pressure unit 15 in turn; Another road pipeline is connected in parallel on the refining bag Argon pipeline for getting rid of airline 20 in the pipeline, is connected with pilot servo formula 2/2-way SV 21 and vacuum breaker 22 in turn, two-way pipeline connection control system.
The system of the utility model is a cover siemens S7-300PLC system, controls according to each mathematical model of smelting stage argon gas demand.Refining bag Argon pipeline is accurately controlled argon flow amount, makes it to satisfy each refinery practice requirement.Get rid of in the pipeline airline and have implementation and blow function by force, and the effect of removing air in the pipeline when starting working.According to smelting production requirement, it is 15-960L/min that the utility model can satisfy each common usage quantity of smelting the stage argon gas, and precision is the requirement of 5L/min.
In the utility model, said reducing valve nominal diameter is G1/2 ".Said gas mass flow amount controller is nominal diameter G1/2 ", flow is (25 ~ 1800Nl/min).Said vacuum breaker nominal diameter is G1/2 ".Said pilot servo formula 2/2-way electromagnetic valve coil voltage is 24V.Said pressure unit range is (0-3MPa).
Compared with prior art, the utility model is easy and simple to handle, need not artificial on duty in the smelting process; Can select different mathematics to carry out the Argon process control automatically according to different steel grades, the argon flow amount precision be high, and operation and maintenance cost is low; Effectively reduce the consumption of argon gas, shortened tap to tap time.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
