Compared with the prior art, the ladle long nozzle argon tank has the advantages that the operation and the management of upper nozzle argon injection are realized, the joint positive pressure value is guaranteed under the condition of the minimum flow, the product quality accidents caused by suction and the problem of casting blank bubble brought by overlarge flow are avoided to the greatest extent, meanwhile, the using amount of argon is also reduced, and the cost is reduced.

Description

The ladle long nozzle argon air box
Technical field
The utility model relates to a kind of continuous casting ladle long nozzle argon air box.
Background technology
In the casting cycle of continuous casting, molten steel in the ladle enters into tundish by ladle mechanism and long nozzle, collector nozzle of ladle wherein is connected by the long nozzle clamper with long nozzle, can not guarantee slitless connection in the connection procedure, the molten steel of rapid flow can produce negative pressure in the steel pouring process, and air can enter in the molten steel by the road seam.Not only can cause the erosion of anti-material, also can cause molten steel nitrogen pick-up, oxide stops up a series of problems such as the mouth of a river, thus need in seam, pass into the inert gas argon gas, to form malleation to prevent the suction of air.But be blown into the quality that too much argon gas also can affect strand.For example the argon gas bubbles in continuous casting billet can produce serious quality problems, even waste product, so need to carry out to the argon gas that is blown into adjusting and the detection of flow and pressure.
Common long nozzle argon air box only has pressure-regulating valve and the flow control valve of import at present, outlet lacks Pressure gauge, can't determine the argon envelope situation between long nozzle and the lower mouth of a river, the size of flow also can only be with operating personnel's micro-judgment, exist uncertainly, can't guarantee in the situation that uses malleation value between minimum discharge assurance seam.Secondly, the environment of steel mill is abominable, particularly water the steel zone, high temperature Gao Regao dust, long nozzle argon air box are installed on the tundish of continuous casting, and this regional space is narrow and small, operating personnel can not arbitrarily monitor flow and the pressure of argon gas at any time, even can cause that source of the gas is turn-offed undiscovered phenomenon by mistake in casting cycle, and causing molten steel nitrogen pick-up, product is defective.
The utility model content
The purpose of this utility model is to solve above-mentioned technical problem, and a kind of ladle long nozzle argon air box is provided.
The purpose of this utility model is achieved through the following technical solutions:
The ladle long nozzle argon air box, comprise the ball valve that is arranged on the argon air box entrance point, the port of export of described ball valve is connected with the input of flow control valve, the output of described flow control valve is connected with the input of pressure-regulating valve, the output of described pressure-regulating valve is connected with the ball valve of the argon air box port of export, also be provided with flow rate measurement valve and pressure detecting valve between the ball valve of described pressure-regulating valve and the argon air box port of export, the output of described pressure-regulating valve is connected with the input of flow rate measurement valve, the output of described flow rate measurement valve is connected with the input of pressure detecting valve, and the output of described pressure detecting valve is connected with the ball valve of the argon air box port of export.
Preferably, described argon air box comprises that also one is used for the PLC control module of record and analysis flow and pressure information, and described PLC control module and flow rate measurement valve and pressure detecting valve are electrically connected.
The beneficial effects of the utility model are mainly reflected in: flow and pressure to port of export argon gas are monitored, and the current signal after will transforming feeds back to the PLC control module of continuous casting master-control room, operation and management to the filling pipe end Argon have been realized, in the situation that minimum discharge has guaranteed seam malleation value, stop air-breathingly, farthest avoided the product quality accident that causes because of air-breathing and the excessive strand air bubble problem that brings of flow, simultaneously also reduce the argon gas consumption, reduced cost.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1: ladle long nozzle argon air box catenation principle schematic diagram of the present utility model.
The specific embodiment
The utility model has disclosed a kind of ladle long nozzle argon air box, as shown in Figure 1, consistent with prior art, comprise the ball valve 1 that is arranged on the argon air box entrance point, the port of export of described ball valve 1 is connected with the input of flow control valve 2, the output of described flow control valve 2 is connected with the input of pressure-regulating valve 3, and the output of described pressure-regulating valve 3 is connected with the ball valve (meaning not shown in the figures) of the argon air box port of export.
Different is, also be provided with flow rate measurement valve 4 and pressure detecting valve 5 between the ball valve of described pressure-regulating valve 3 and the argon air box port of export, the output of described pressure-regulating valve 3 is connected with the input of flow rate measurement valve 4, the output of described flow rate measurement valve 4 is connected with the input of pressure detecting valve 5, and the output of described pressure detecting valve 3 is connected with the ball valve of the argon air box port of export.For the argon flow amount in the argon air box and pressure are better controlled analysis, described argon air box also comprises a PLC control module 6.Described PLC control module 6 is electrically connected with flow rate measurement valve 4 and pressure detecting valve 5.The value of detecting is monitored by PLC control module 6, reports to the police and management.
The beneficial effect that the utility model produces is, by the monitoring to outlet pressure, argon envelope malleation value that can on-line monitoring long nozzle seam has been stopped the air-breathing product quality of bringing of long nozzle and anti-material safety problem (corroding anti-material because of air-breathing).
Also guarantee argon flow amount minimum on the basis of malleation value by the monitoring to argon flow amount, to reduce the argon gas amount in the molten steel, reduced the quality accident that in strand, causes because of Argon Bubble.
By the feedback of host computer to argon flow amount and pressure, made things convenient for operation supervise and control and data management and reviewed, realized the automatic management of argon envelope.
The utility model still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of the utility model.
