Description
Technical field
The present invention relates to continuous casting technical fields, arrange especially suitable for a kind of use for laboratory small billet vertical casting machine roller
And its application method.
Background technique
Vertical casting machine essential characteristic is: each main equipment of conticaster: crystallizer and its vibration device, secondary cooling branch
Support guiding device, throwing equipment and cutter device etc. are configured from top to bottom in same vertical production line, and in casting process
Slab is not by any imposed deformation process.Thus have the advantages that (1) due to molten steel vertical injection crystallizer in, four
All cooling conditions are identical, can easily be accommodated control, thus crystallization and freezing easily reaches optimum state.And various nonmetal inclusions in molten steel
Object is easy to float, and inclusion in casting blank is minimum, and cross section crystalline structure is symmetrical.(2) conticaster main equipment structure is simple, and
A set of straightener can be saved.(3) slab is not acted on during crystallization and freezing by any mechanical external force.To obtain high quality
Slab creates more favorable condition.
Patent application CN103648687 " method and vertical casting machine for metal melt manufacture heavy slab ", wherein
In vertical crystallizer casting is with being still the continuous casting steel billet of the wick-containing of liquid, subsequent with multiple strand guide sections
Continue to guide the continuous casting steel billet in strand guide mechanism, the strand guide section has at least some be driven wherein
Strand guide rod that is dynamic and/or can depressing, continuous casting steel billet device to be cut after complete solidification are cut into centainly
Then the slab of length exports the slab.The method is more than 300mm particularly between 400- mainly for manufacture thickness
Between 800mm and width dimensions are the continuous casting steel billet of 900-3200mm, in the equipment section after strand guide structure,
In the case where not supporting and guiding the continuous casting steel billet solidified completely, the deviation of the continuous casting steel billet and vertical line is detected, and improve or subtract
Small depressing force, and/or change the position for the strand guide reel being placed in front of or after unsupported equipment section, thus exist
Continuous casting steel billet makes continuous casting steel billet replication to the vertical line before reaching cutter device.But it is mainly for wide and thick slab, to small
Square billet depresses effect and the promotion effect of internal soundness is unobvious.
Patent application CN201264080Y " billet caster fan-shaped section Integral quick change structure and billet caster ",
The billet caster of fan-shaped section Integral quick change structure realizes entirety or the chilling spray part of billet caster fan-shaped section
Quick-replaceable and maintenance, and effectively promoted billet caster operating rate, improve slab quality.
Single chassis is arranged in horizontal segment in patent application CN206527325U " billet caster ", the billet caster
Withdrawal straightening machine can be individually replaced maintenance, when producing the small billet of different steel grades, carry out different drafts using different withdrawal straightening machines
Pressure, can satisfy the demand of different steel grade different castings and different drafts, and withdrawal straightening machine is located at horizontal segment, is conducive to equipment
Lifting and maintenance, while meeting and being required under weight under the conditions of high pulling rate, it is not easy to crack.But the above-mentioned main needle of two equipment
To segmental arc, without reference to vertical casting machine, circular-arc type continuous casting machine is unfavorable for the inclusion floating of small billet, and is easy to inner arc
Enrichment will cause field trash segregation, and casting machine occupied area is bigger than vertical casting machine, while all equipment related with arc in casting machine
Processing and manufacturing and the installation of segmental arc, centering it is more troublesome.
Summary of the invention
