Description
Technical field
The present invention relates to a kind of metallurgical continuous casting processing unit, clean, about a kind of, the supplementary unit that Con casting ladle stays cold steel, foreign material temporarily specifically.
Background technology
Slab caster long nozzle is that one is installed on below ladle, for protecting, guide the mouth of a river of molten steel from ladle inflow tundish. Long nozzle is one of three-major-items in even casting is produced. Mechanical manipulator holds up long nozzle and is installed on ladle nozzle, after a front bag molten steel casting, utilizes mechanical manipulator to unload long nozzle, treats that the revolution of next bag molten steel puts in place, holds up by mechanical manipulator and be installed on next bag ladle, then carry out molten steel casting.
At the end of a front bag molten steel casting; long water gap bowl oral area can adhere to some a small amount of residual steel usually; or residue in the foreign material of sealing-ring; if not removed when being totally namely installed on next bag molten steel; the mouth of a river can be caused to tilt, and then cause stopping property difference and suck air and cause the productions such as secondary oxidation of steel and quality problems. As shown in Figure 1, current CC at home & abroad producer normally adopts manual instrument 9 to carry out scratching bowl mouth 10 ' and its inwall 10 of long nozzle 10 " the adhesion thing of removing on it. There is following shortcoming in the mode that this kind of prior art adopts manual instrument 9 to carry out cleaning the residue of long nozzle:
Adopt the manual instrument 9 of manual hand manipulation, usually the clean long nozzle of cleaning need to spend five minutes, this can affect the performance of continuous caster production capacity, long period injects in tundish without molten steel simultaneously, molten steel tonnage in tundish can be caused to reduce, thus cause argon wave in crystallizer to move, and then affect slab quality;
Manually the adhesion thing of cleaning bowl mouth is often cleared up not thoroughly, not totally, be there is the hidden danger causing stopping property difference, thus causes sucking air, and the compositions such as strand nitrogen, oxygen are acted improperly;
The residual usual adhesive power of cold steel adhered to is strong, and manually cleaning bowl mouth labour intensity is big, difficulty height.
Summary of the invention
