Slab caster long nozzle is that one is installed on ladle below, for protecting, guide molten steel to flow into the mouth of a river of tundish from ladle.Long nozzle is one of three-major-items in continuous casting is produced.Manipulator holds up long nozzle and is installed on ladle nozzle, after last bag molten steel casting, utilizes manipulator to unload long nozzle, treats that next Baogang's water revolution puts in place, is installed on next Baogang by manipulator picking-up and wraps, then carry out molten steel casting.
When last bag molten steel casting finishes; long water gap bowl oral area can adhere to some a small amount of residual steel conventionally; or residue in the foreign material of sealing ring; totally be installed on next Baogang water during if do not remove; can cause the mouth of a river to tilt, and then it is poor and air amount causes the productions such as secondary oxidation of steel and quality problems to cause sealing.As shown in Figure 1, at present CC at home & abroad producer normally adopts hand-operated tools 9 to scratch the rim of a bowl portion 10 ' and its inwall 10 of long nozzle 10 " remove the bur on it.There is following shortcoming in the mode that this employing hand-operated tools 9 of prior art cleans the residue of long nozzle:
Adopt operator power driven tools 9 manually, conventionally the clean long nozzle of cleaning need spend five-minute period, this can affect the performance of conticaster production capacity, long period injects in tundish without molten steel simultaneously, can cause molten steel tonnage in tundish to reduce, thereby cause argon gas fluctuation in crystallizer, and then affect slab quality;
Manually the bur of cleaning the rim of a bowl often clear up not thoroughly, unclean, exist and cause the poor hidden danger of sealing, thereby cause air amount, and make the compositions such as strand nitrogen, oxygen offscale;
The common adhesion of residual cold steel adhering to is strong, manually cleans the rim of a bowl labour intensity large, and difficulty is high.
Summary of the invention
The object of this invention is to provide a kind of continuous casting ladle long nozzle clearing apparatus and cleaning method, can be fast, thoroughly clean residual cold steel, the foreign material of continuous casting ladle long water gap bowl oral area and long nozzle inwall simultaneously.
A kind of continuous casting ladle long nozzle clearing apparatus is provided according to an aspect of the present invention, it is characterized in that, comprising: the motor that coaxial line is arranged, a saddle and a cleaning blade wheel; Wherein said motor is arranged in described saddle, the wheel hub of the power output shaft of described motor and described cleaning blade wheel is threaded connection, the space that the inwall that described cleaning blade wheel is positioned at saddle limits, the periphery wall of cleaning blade wheel is evenly equipped with at least two blades, the lower surface that each blade arrangement becomes to stretch out described saddle.
In one embodiment, described at least two blades are three blades.
Preferably, be fixed with branched oxygen jet in described saddle, each oxygen jet extends into respectively in the space that the inwall of described cleaning blade wheel limits vertically.
In one embodiment, described branched oxygen jet is four oxygen jets, each oxygen jet respectively around described axis arranged in four orientation.
Described each oxygen jet connects source of the gas by oxygen hose.
Described motor connects power supply by electric wire.
Described oxygen hose and electric wire are located in a protecting pipe.
Oxygen, power switch are installed on described protecting pipe.
A kind of continuous casting ladle long nozzle cleaning method is provided according to a further aspect of the invention, implement by a continuous casting ladle long nozzle clearing apparatus, this device comprises a motor, a saddle and the cleaning blade wheel that coaxial line is arranged, the periphery wall of cleaning blade wheel is evenly equipped with at least two blades; Described method comprises:
Motor is arranged in described saddle;
