Description
Technical field
The utility model belongs to technical field of ferrous metallurgy, and more particularly to one kind cuts equipment for six stream caster base fire
Cutting knurl blow device.
Background technology
At present, conticaster mainly produces rolled steel tube continuous casting circular tube blank, round billet section include Φ 210mm, Φ 200mm,
Φ 180mm, Φ 160mm and Φ 150mm totally 5 sections.Strand is split using gas flame cuttiug technology after continuous blank-discharging, and
Cutting knurl is then the slag that continuous casting billet is attached to continuous casting billet lower surface after steel fusing during fire is cut, its size and slot and casting
Base section is relevant.
The cutting warty condition of current each section is that big cross section round billet (Φ 210mm, Φ 200mm) cutting knurl thickness is 8mm, small
Section round blank (Φ 180mm, Φ 160mm, Φ 150mm) cutting knurl thickness is 5mm.Pass through big cross section round billet (Φ after cutting
210mm, Φ 200mm) cutting knurl thickness control is within 5mm, light section round billet (Φ 180mm, Φ 160mm, Φ 150mm) cutting
Knurl thickness control is within 4mm.
With the continued downturn of steel industry situation, downstream user proposes higher and higher require to product quality.Nearly one
Over 2 years, downstream user repeatedly points out that our factory large round billet cutting knurl influences its rolled steel pipes head-tail presentation quality, therefore needs
The cutting knurl of round billet is handled.
The content of the invention
The utility model provides a kind of use compressed air purging to solve technical problem present in known technology
Mode, reduce the adhesion amount of the slag that produces after steel billet fusing in continuous casting billet lower surface, is used for the size for reducing cutting knurl
Six stream caster base fire cut the cutting knurl blow device in equipment.
The utility model is adopted the technical scheme that to solve technical problem present in known technology：
A kind of six stream caster base fire that are used for cut cutting knurl blow device in equipment, it is characterised in that：Including six groups of purgings
Component, every group of sweep module includes being connected pneumatic operated valve with compressed gas source, and metal hose, the gold are connected in the outlet of pneumatic operated valve
Belong to the other end connection reducing bend of flexible pipe, the other end connection welded tube of the reducing bend, the end connection of the welded tube is straight
Angle elbow, air nozzle is provided with the end of elbow bend；Electromagnetic relay for controlling pneumatic operated valve working condition, electromagnetism after
Electrical equipment, which is connected on, to be formed and is closed back by the clamping relay and power supply lock for controlling to clamp strand state in strand cutting equipment
Lu Shang.
The utility model can also use following technical measures：
The inlet end of the reducing bend is 1/2 ", the outlet side of reducing bend is 3/4 ".
The utility model has the advantages and positive effects of：Because the utility model uses above-mentioned technical proposal, use
The cutting knurl produced when compressed air is to cutting carries out external force purging, reduces the slag produced after steel billet fusing in continuous casting billet following table
The adhesion amount in face；Six streams are respectively mounted with blow device, inlet manifold draws outside cutting car car body, purge position is aligned
The lower surface of strand, require in terms of nozzle gas exit in the way of flattening to external diffusion, accurately can enter to cutting knurl
Row purging can guarantee that again does not injure casting billet surface；To reduce influence of the compressed air to slab cooling, while reducing compressed air
Consumption, on the compressed air hose of each stream plus interlocking signal, making the compressed air hose only start purging when stepping up cutting.
In addition, the utility model also has simple in construction, the advantages of mounting and adjusting facilitates.

Embodiment
For invention, features and effects of the present utility model can be further appreciated that, following examples are hereby enumerated, and coordinate
Accompanying drawing describes in detail as follows：
Refer to Fig. 1 and Fig. 2, a kind of six stream caster base fire that are used for cut cutting knurl blow device in equipment, including six groups
Sweep module, every group of sweep module includes being connected pneumatic operated valve 1 with compressed gas source, and metal hose 2 is connected in the outlet of pneumatic operated valve,
The other end connection reducing bend 3 of the metal hose, the inlet end of the reducing bend is preferably 1/2 ", reducing bend goes out
Gas end is preferably 3/4 ".The elbow bend of the other end connection welded tube 4 of the reducing bend, the end connection 3/4 of the welded tube "
5,3/4 is provided with the end of elbow bend " air nozzle 6；Electromagnetic relay for controlling pneumatic operated valve working condition, electromagnetism
Relay is connected on forms closure by the clamping relay and power supply lock for controlling to clamp strand state in strand cutting equipment
On loop, so reach only step up cutting when start purge operation.Above-mentioned electromagnetic relay and the folder of control pinching action
Tight relay and power supply lock belong to known electric elements, and in the market purchase can be used.
Using above-mentioned technical proposal, the cutting knurl produced during using compressed air to cutting carries out external force purging, reduces steel
Adhesion amount of the slag produced after base fusing in continuous casting billet lower surface；Six streams are respectively mounted with blow device, inlet manifold from
Drawn outside cutting car car body, require gas in exit with flattening in terms of purge position to be aligned to the lower surface of strand, nozzle
Mode to external diffusion, accurately cutting knurl can purge and can guarantee that and do not injure casting billet surface；To reduce compressed air pair
The influence of slab cooling, while reducing the consumption of compressed air, to adding interlocking signal on the compressed air hose of each stream, makes the pressure
Contracting air hose only starts purging when stepping up cutting.In addition, the utility model also has simple in construction, it is excellent that mounting and adjusting is convenient etc.
