In order to realize the aim, the utility model provides a continuous casting ladle long nozzle protection pouring device, which comprises an annular blowing pipe, a vent pipe and a quick change connector; wherein the content of the first and second substances,
the injection pipe is arranged around the periphery of the long nozzle of the continuous casting ladle along the circumferential direction and is communicated with one end of the vent pipe; the other end of the breather pipe is provided with a quick-change connector and is communicated with the argon gas supply pipeline through the quick-change connector;
a plurality of argon blowing holes are formed in the inner wall of the blowing pipe at intervals along the circumferential direction, and the argon blowing holes are all towards the continuous casting ladle long nozzle to blow argon so as to form argon airflow protection.
Preferably, the injection pipe is arranged in the middle of the long nozzle of the continuous casting ladle.
Preferably, the outer wall of the continuous casting ladle long nozzle extends outwards to form a mechanism protection plate, and the mechanism protection plate is positioned below the injection pipe and used for supporting and fixing the injection pipe.
Preferably, the blowing pipe is fixed to the mechanism guard by a plurality of fixed base blocks.
Preferably, the quick-change connector is a KZE3-8 connector.
Preferably, the mechanism guard is horizontally disposed.
According to the technical scheme, the utility model discloses connect the argon gas pipe, connect a quick change coupler through metal collapsible tube, annular argon gas pipe is connected to the quick change coupler of rethread, when the big packet mouth of a river pneumatic cylinder of installation, with the quick change coupler butt joint and open the argon gas, makes its regional argon gas flow that forms to reach the argon protection. Therefore, the annular ring is used for passing through argon, so that the ladle long nozzle is positioned in the pouring process to form an argon sealing area, and the contact with air is avoided, thereby reducing the process increase of N and greatly improving the quality of steel.
Other features and advantages of the present invention will be described in detail in the detailed description which follows.
