Abstract
The utility model discloses a continuous casting hand cleaning gun nozzle. A cleaning air hole is arranged at the center of a body, and a plurality of small holes are further arranged in the circumferential directions of the cleaning air holes, wherein the cross sections of the cleaning air holes are crescent. The continuous casting hand cleaning gun nozzle changes the shape of a cleaning gun from a circular shape to a crescent shape, and therefore, air flow sprayed out of the cleaning nozzle is also changed from the circular shape to the crescent shape. In operation, when the air flow moves parallel to a corner of a plate blank, the effect of chamfering an arc angle of the corner is easily achieved.
Description
Technical field
The utility model relates to continuous casting installation for casting, the clear rifle nozzle of particularly a kind of continuous casting hand.
Background technology
Need use the cleaning rifle during cleaning of the slab arc angle of falling the great circle, existing cleaning rifle nozzle is referring to Fig. 1, and it exists the slab rounding arc angle activity duration long, and main cause is that hand is cleared up rifle designs of nozzles unreasonable structure:
1, spray gun cleaning mouth aperture is too little, influences the flux of oxygen rifle Oxygen Flow, the cutting steam insufficient strength.
2, spray gun cleaning mouth be shaped as circle, the air-flow of ejection also is a circle like this, parallel with the slab bight when mobile when air-flow, circular air-flow is difficult to reach the effect of bight rounding arc angle.
Summary of the invention
The purpose of the utility model is to design the clear rifle nozzle of a kind of continuous casting hand, can effectively shorten the slab rounding arc angle activity duration, improves the clear operating efficiency of continuous casting hand.
For achieving the above object, the technical scheme of the utility model is:
The clear rifle nozzle of a kind of continuous casting hand, the cleaning pore is established at its body center, also establishes some apertures along cleaning pore circumferencial direction; It is characterized in that described cleaning pore section is a crescent.
Further, described cleaning pore section is a half moon.
Again, described cleaning air vent aperture is Φ 18～20mm, and the cleaning oxygen aperture of former cleaning mouth is amplified to Φ 18 by Φ 13, and close-fitting is bumped into cutting torch, and the flux of the nozzle oxygen rifle Oxygen Flow after the improvement increases, the cutting steam intensity enhancing.
The beneficial effect of the utility model
The utility model changes cleaning rifle nozzle form, makes crescent into by circle, and the air-flow of clearing up the mouth ejection like this also changes crescent into by circle.During operation, air-flow is parallel with the slab bight when mobile, reaches the effect of bight rounding arc angle easily.
Description of drawings
Fig. 1 is the structural representation of existing cleaning mouth.
Fig. 2 is the structural representation of the utility model embodiment.
Fig. 3 is the vertical view of Fig. 2.
The specific embodiment
Referring to Fig. 2, Fig. 3, the clear rifle nozzle of a kind of continuous casting hand of the utility model, cleaning pore 101 is established at its body 1 center, also establishes some apertures 102 along cleaning pore 101 circumferencial directions; Described cleaning pore 101 sections are half moon.Described cleaning air vent aperture is Φ 18～20mm.
After the utility model used, the cleaning ability of the slab arc angle of falling the great circle improved greatly.Make the original slab bight rounding arc angle technology of three moulding of dividing of the clear operation of hand as long as once just can reach technological effect.
It is 65.2min that original slab of chamfering needs the time.
Adopting the utility model to implement slab of back chamfering needs the time to calculate with optimum efficiency:
4 * (5 meters/minute of 5 meters/minute+10 meters ÷ of 2 meters/minute+10 meters ÷ of 10 meters ÷)=36 minutes.Work efficiency improves 81.11%.
Claims (3)
1. clear rifle nozzle of continuous casting hand, the cleaning pore is established at its body center, also establishes some apertures along cleaning pore circumferencial direction; It is characterized in that described cleaning pore section is a crescent.
2. the clear rifle nozzle of cleaning mouth continuous casting hand as claimed in claim 1 is characterized in that described cleaning pore section is a half moon.
3. according to claim 1 or claim 2 the clear rifle nozzle of cleaning mouth continuous casting hand is characterized in that described cleaning air vent aperture is Φ 18～20mm.
