Description
Technical field
The present invention relates to a kind of billet casters, belong to continuous casting field, and in particular to a kind of vertical drawing of small billet
Billet continuous casting machine and soft reduction process device.
Background technique
It is width direction that traditional billet caster, which is all made of wide face, and leptoprosopy is the mode that thickness puts down upper and lower two nip rolls,
Width direction is constrained, cooperation secondary cooling system sprays casting billet surface, guarantees that green shell does not occur big bulge amount.For
Meet the quality requirement of variety steel, reduce slab internal segregation and loose, also mostly use M-EMS or crystallizer,
The combination that the double electricity of solidification end stir, and the configuration that electricity stirs technology is only suitable for low pulling rate production, after pulling rate increases, wick-containing adds
Long, internal soundness can deteriorate rapidly, cause slab quality that expected requirement is not achieved.And casting need to be accurately adjusted when slab send and rolls
Base thickness and width direction to guarantee that slab can pass through inlet of rolling mill, but when tilting gear breaks down, will lead to casting
Base can not influence subsequent double steel, and then influence productivity effect by inlet of rolling mill.It is therefore proposed that a kind of vertical throwing of small billet
Conticaster and soft reduction process device to production high-quality slab and ensure that production is most important.
Patent application CN102000789A " a kind of conticaster and small billet slighter compress device ", patent application
CN106345977A " high speed small billet or small round billet continuous casting machine secondary cooling method and device " and patent application
What CN206527325U " billet caster " the studies above all proposed is the throwing mode that wide face is width direction, although also adopting
With screwdown gear but steel grade covering surface is low, cannot achieve the actual field production requirement in the multibreak face of more steel grades, and depresses energy
Power is limited, cannot achieve efficient pressure.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, provided by the invention to be designed to provide a kind of vertical throwing of small billet
Conticaster and soft reduction process device can be realized vertical throwing and can be realized in the case where guaranteeing Inner Quality of Billet
Press function.
To achieve the goals above, technical scheme is as follows:
A kind of vertical throwing conticaster of small billet and soft reduction process device, the vertical throwing conticaster of the small billet, foot
Roll segment region nip rolls is all made of four sides clamping casting roll, i.e., is constrained in the width and thickness direction of slab.
The vertical throwing conticaster of the small billet and soft reduction process device, secondary cooling zone clamp casting roll using segmentation four sides,
I.e. in secondary cooling zone step-by-step arrangement at least three groups of four sides niproll column, remaining is snub pulley.
The vertical throwing conticaster of the small billet and soft reduction process device, four sides niproll roller diameter range are 85-
110mm, snub pulley roller diameter range are 190-210mm.
The vertical throwing conticaster of the small billet and soft reduction process device, the setting of soft reduction process device is at casting blank solidification end
End regions, specifically in solid rate fsBetween=0.4-0.9.
The vertical throwing conticaster of the small billet and soft reduction process device, soft reduction process device use single chassis form for
Single chassis withdrawal straightening machine with press function, every group of rack are made of upper pressure roller and lower compression roller.
The vertical throwing conticaster of the small billet and soft reduction process device, the roll gap formed between upper and lower pressure roller and
The usage quantity of soft reduction process device is corresponding with the specification of small billet, steel grade and live Actual Casting Speed.
The vertical throwing conticaster of the small billet and soft reduction process device, the soft reduction process device overall reduction are
20-25mm, single chassis drafts 4-6mm.
The vertical throwing conticaster of the small billet and soft reduction process device, withdrawal straightening machine up-down rollers diameter range are 400-
425mm。
The invention has the benefit that slab central dense degree can be effectively improved, make the central pipe of slab, is segregated energy
It is effectively controlled.Guarantee that slab can effectively control casting blank bulging amount under vertical throwing mode and guarantee casting blank shape, after being
Continuous slab is laid the groundwork with square into steel rolling process after soft reduction process.
