Abstract
The utility model provides a big bell of LF stove is equipped with round argon gas pipe along the inboard on big bell, the equidistant stainless steel nozzle that is equipped with is gone up to the argon gas pipe, and the argon gas union coupling is on the argon gas pipeline. Before the LF stove is handled, through the stainless steel nozzle argon gas of jetting in to big bell, utilize the argon gas with original air escape earlier, protect the molten steel. 3 the processing molten steel of renewaling after minute remains bloing in in succession of argon gas throughout handling the molten steel in -process, pushs forward up to the molten steel. The utility model discloses can effectively prevent to inhale nitrogen and oxygen uptake phenomenon when the LF stove from handling, reduce the molten steel oxidation and mix with, improvement mass of molten steel.
Description
Technical field
The utility model belongs to technical field of mechanical equipment, particularly a kind of large bell of LF stove with argon gas blowing device.
Background technology
Large bell is provided with above LF stove, in the process of carrying out molten steel stirring and intensification, on ladle along and large bell between, inevitably inhale greatly the phenomenon of nitrogen and oxygen uptake between bell and electrode, cause molten steel oxidation and produce oxide inclusion, the direct quality affecting molten steel, especially for production Clean Steel with concerning inclusion content requires low steel grade, very large difficulty will be caused.
Summary of the invention
The utility model aims to provide one and can prevent from occurring inhaling nitrogen and oxygen uptake phenomenon during the process of LF stove, reduces molten steel oxidation and is mingled with, improving the large bell of LF stove of steel quality.
For reaching this object, the utility model takes following technical solution:
The large bell of a kind of LF stove, it is characterized in that, large bell is equipped with a circle tunger tube along inner side, tunger tube is equidistantly provided with stainless steel nozzle, tunger tube is connected on argon gas pipeline.
Positively effect of the present utility model is:
Suction nitrogen when the utility model effectively can prevent the process of LF stove and oxygen uptake phenomenon, reduce molten steel oxidation and be mingled with, and improves steel quality.
Accompanying drawing explanation
Fig. 1 is the large bell schematic diagram of LF stove.
In figure: large bell 1, tunger tube 2, stainless steel nozzle 3.
Embodiment
As seen from Figure 1, the utility model is on large bell 1, installed a circle tunger tube 2 along inner side, and tunger tube 2 is equidistantly installed on multiple stainless steel nozzle 3, the entrance end of tunger tube 2 is connected on argon gas pipeline.
Using method of the present utility model is:
Before the process of LF stove, first to be jetted in large bell 1 argon gas by stainless steel nozzle 3, utilize argon gas to be discharged by original air, molten steel is protected.Start again after 3 minutes to process molten steel, in process molten steel process, remain being blown into continuously of argon gas, until molten steel takes out of.
