Description
Technical field
This utility model relates to the outer liquid steel dephosphorization of a kind of stove and processes system, belongs to metallurgy industry steelmaking equipment technical field.
Background technology
In intermediate frequency furnace smelting molten steel process, owing to technique not meeting the dynamic conditions of dephosphorization, there is no again slag making dephosphorization means, it is desirable to it is relatively difficult for obtaining low-phosphorous (phosphorus content is less than 0.020%) molten steel.At present, in actual production process, generally adopting before intermediate frequency furnace tapping or in tapping process, be directly added into the mode of Dephosphorising agent, reach the purpose of dephosphorization inside ladle, this dephosphorization treatment mode, dephosphorization effect is bad, and labor strength is big.
Utility model content
This utility model purpose is to provide the outer liquid steel dephosphorization of a kind of stove and processes system, uses spray gun that the raw material needed for dephosphorization is jetted to ladle bottom, and ladle bottom blowing argon simultaneously is created good dynamic conditions for dephosphorization, solved Problems existing in background technology.
The technical solution of the utility model is:
The outer liquid steel dephosphorization of a kind of stove processes system, comprise spray gun, ladle, argon gas blowing device, Dephosphorising agent storage tank, device for removing slag and slag ladle, one end of spray gun is located at the bottom of ladle, the other end of spray gun is connected with Dephosphorising agent storage tank by pipeline, the top of ladle is provided with device for removing slag, device for removing slag is connected with slag ladle, and the bottom of ladle is provided with argon gas blowing device.
Described spray gun is additionally provided with lifting device.
Adopting this utility model technology, after intermediate frequency furnace tapping terminates, application spray gun jets the raw material needed for dephosphorization to ladle bottom from Dephosphorising agent storage tank, ladle bottom blowing argon simultaneously, create good dynamic conditions for dephosphorization, finally molten steel is taken off slag operation, obtain low-phosphorus molten steel.
The beneficial effects of the utility model are: can create good dynamic conditions for dephosphorization, it is achieved dephosphorization rate 60%～80%, and simple in construction reduces labor strength.

In figure: spray gun 1, ladle 2, argon gas blowing device 3, Dephosphorising agent storage tank 4, device for removing slag 5, slag ladle 6, lifting device 7.
Detailed description of the invention
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1, the outer liquid steel dephosphorization of a kind of stove processes system, comprise spray gun 1, ladle 2, argon gas blowing device 3, Dephosphorising agent storage tank 4, device for removing slag 5 and slag ladle 6, one end of spray gun 1 is located at the bottom of ladle 2, the other end of spray gun 1 is connected with Dephosphorising agent storage tank 4 by pipeline, the top of ladle 2 is provided with device for removing slag 5, and device for removing slag 5 is connected with slag ladle 6, and the bottom of ladle 2 is provided with argon gas blowing device 3.
In the present embodiment, adopting double; two spray gun, double; two spray guns also have lifting device and rotary apparatus.Implement singly blow Dephosphorising agent liquid steel dephosphorization process, be drying nitrogen.All air conveying operations and complementary operation are used that drying nitrogen is implemented.It addition, also comprise Dephosphorising agent storage and conveyer device, it is made up of Dephosphorising agent storage warehouse, transfer pot, belt conveyer, belt conveyer scale, winding-up tank and valve and pipeline.Powder-storage bin is provided with cleaner unit.Warehouse ensures to send in transfer pot in gravity mode rapidly, easily by Dephosphorising agent.Calx is sent into winding-up tank by transfer pot, and metering winding-up tank can require regulation blowing flow according to spray gun dephosphorization；Iron scale and fluorite are sent directly into tremie pipe by belt conveyer scale and belt conveyor and enter molten steel.
Liquid steel dephosphorization process is controlled by PC work station and PLC by master operating station, and generally, all of operating process is all automatically performed, and various actions have strict operation order and constraint, it is prevented that maloperation and blocking valve pipe occur.Control whole technical process with PC work station and PLC, including calculating winding-up amount, what point opens auxiliary air blowing road, what some automatic spraying Dephosphorising agent, regulation blowing speed, dynamic insert spray gun, promote spray gun, stop spray gun and stop the supple of gas or steam, feedstock vessel aerofluxus feed supplement, start ladle car to winding-up position and position of skimming, the slag car runs and connection smoke discharging dust removing system.PLC Cinder Machine has chain.
Whole process to set up process modeling, makes blowing process direct motion, with minimum Dephosphorising agent under the premise reaching target phosphorus.The consumption of Dephosphorising agent to be subject to the impact of tens factors, only to 5 major variable factors and the original phosphorus of molten steel on actual industrial operates, molten steel original temperature, handled molten steel amount, target phosphorus, Dephosphorising agent inputs process modeling containing amount of metal, namely process modeling calculates the injecting velocity of this stove different periods, the load volume size of this stove different periods, always jet the time, Dephosphorising agent total amount consumed also stores in a computer, demonstrate above-mentioned numerical value on the lcd screen simultaneously, injecting velocity number be by computer control valve opening, load volume size is that the aperture by computer control flow control valve matches with high-precision effusion meter.Simultaneously in order to increase the motility of technological operation, under automated manner, injecting velocity, load volume and initial phosphorus can artificially be interfered, and when artificial interference injecting velocity, injecting velocity adjustable, total winding-up time will change therewith；When artificial interference load volume, load volume and Dephosphorising agent total amount consumed will change therewith.
Argon gas blowing device 3 in this utility model, device for removing slag 5 and spray gun lifting device 7 and rotary apparatus are the art common device, are the art known technology contents.
