Description

Big camber radius plectane base compatibility conticaster and its technique
Technical field
The invention belongs to steels to produce continuous casting installation for casting field, be related to a kind of compatible conticaster of big camber radius round billet slab and Its technique.
Background technique
For normal slab caster type with vertical bending type, arc radius is based on 6m~10m.Existing conticaster produces section 600/700/800 round billet continuous casting machine of φ, production type are round billet, design production capacity 50Wt/.
According to the market demand, big camber is now needed to have 200mm × (550~850) mm slab production capacity, design production capacity Reach the conticaster of 50Wt/.Home and abroad there is no the pass of the compatible conticaster of big camber plectane base mutually to report.
Summary of the invention
The present invention discloses a kind of compatible conticaster of big camber radius round billet slab and technique, it is therefore an objective to use this compatibility continuous casting The continuous casting steel billet that machine and process matched therewith are able to produce macrostructure, density reaches quality standards.
Technical solution, equipment aspect are that 600/700/800 round billet section of 16.5m big cross section φ increases camber in existing radius Radius is 16.485m, and section is 200mm × (550~850) mm slab caster, by converting different crystallizer passes and attached Belong to facility and realizes round billet production compatible with slab;
The compatible conticaster is by the tundish of round billet continuous casting machine, crystallizer, fan-shaped section, two cold row's steam, withdrawal straightening machine, fire It is formed after cutting machine, ejection roller way, dummy bar, off-line device, the transformation of automated procedures man-machine interface;
The compatible continuous casting tundish is (1) in order to guarantee that invasive nozzle is in rectangular crystallizer center, rectangular bloom Interior outer arc spacing center and round billet centre deviation 180mm, therefore (5) former round billet mouth of a river position is moved forward 180mm slab to after being transformed (4), (3) former round billet mouth of a river center line moves to transformation after (2) slab mouth of a river center line, changes tundish immersion water for mouth of a river position Mouth position, water outlet cross section (see Fig. 1);
The compatible conticaster plate slab crystallizer designs and manufactures based on retaining large round billet conticaster crystallizer, will (6) the crystalliser of plate slab crystallizer (7) passes through connection bolt and is (8) fixed on original large round billet continuous casting machine crystallizer vibration platform frame (9) upper (see Fig. 2), guarantees the fast and convenient replacement of crystallizer;Plate slab crystallizer, section is 200mm × (550~850) mm, wide Degree is offline adjustable, offline to adjust wide movement;Plate slab crystallizer is consistent with original vibration interface, and the wide face of plate slab crystallizer is bolted In crystalliser, wide face foot roller is fixed in crystalliser;Narrow copper plate is bolted on " plug-in type " support On plate, narrow-face foot roller and nozzle are fixed in leptoprosopy support plate;
The compatible continuous casting machine fan-shaped segment is led in one section of round billet sector, a set of whole slab 1&2 sector of two fragment positions installation To section;Fan-shaped 3~5 sections of similar 1&2 sections of design forms of sector and round billet section sequence correspond, and overall shrinkage roller arranges (see Fig. 3);
The compatible continuous casting machine tension leveling machine uses multipoint straightening, that is, utilizes 3,4,5,7,9,15 frame straightenings of round billet continuous casting machine Machine participates in the throwing and straightening operation of slab, wherein 15 framves are to send dummy ingot sortie, increase roller set, does not change other component;Slab And round billet thickness deviation is larger, carries out hydraulic cylinder changing to used withdrawal straightening machine sortie;Improved withdrawal straightening machine in view of Decelerating motor installation site is lower and upper roller stroke increases, and causes Hooks coupling universal coupling bending offset angle inadequate, to straightening motor Compatible production is realized in mounting height adjustment;Required depressing force is produced to slab and reprogram control (see figure using sortie 4), implementation pattern switching automatic adjustment;
The compatible conticaster fire cuts machine and improves and optimizates imitative arc cutting process, increases slab operation interface, and fire cuts machine ginseng Number setting interface (see Fig. 5) realizes that different section, different cutting curves can operate, and single rifle and rush-harvesting and rush-planting can cut slab;
The compatible ejection roller way of continuous casting machine is substantially carried out rollgang guiding transformation, since slab, round billet base type are different, The guiding device for needing a kind of two kinds of production models of compatibility is oriented to using the movable adjustable spacing of original navigation designing;
The compatible dummy bar of continuous casting machine uses chain dumming bar, and detection mode uses Grating examinations, and shape uses slab Pass structure;
The compatible conticaster off-line device increases the offline centering of slab and verifying attachment newly;
The relevant control program of section and man-machine picture are increased newly after the compatible conticaster automated procedures man-machine interface transformation Face: the main mode including slab caster is converted, the chain control of slab caster, the roll gap adjustment of withdrawal straightening machine, and HMI is drawn Face increases section selection, as shown in fig. 6, dummy ingot, throwing, dummy bar storage automation control program and HMI picture is sent to repair automatically Change;Increase automatically controlled two cold water spray equipment and instrument facility and the corresponding HMI picture of modification and controlling curve.
Usually empirically determine casting machine radius R and thickness H relationship are as follows: R=(40~50) H.For the slab of 200mm thickness For section, domestic conventional plate blank conticaster arc radius is 40~50 times of thickness, thus arc radius 8m~10m it Between, it can satisfy mass property requirement.And the conticaster radius R of northeast special steel group Dalian special steel steel mill transformation is thickness 82.425 times of H, far beyond the design concept of conventional plate blank.Slab caster arc radius is bigger, and casting machine height increases, and throws It is higher to provide construction cost, since the static pressure of molten steel becomes larger, easily causes bulge deformation, straightening deformation problem, but casting machine radius increases Greatly, the consistency of the larger static pressure of molten steel, slab will increase, and be conducive to the control of product quality.
Technical solution, process aspect design tundish immersed nozzle position, crystallizer size and taper value, slab fan Shape section opening degree, adjustment slab allow pulling rate, secondary cooling parameter and mode, secondary cooling water mouth zoning arrangement parameter, change straightening Machine pressure value.
By the round billet middle water containing opening position of middle packet tank to the mobile 180mm in bale panoramic tables direction, changes tundish and immerse Formula mouth of a river position;
Offline to adjust crystallizer width, taper value, mouth width degree, taper depend on needed for steel grade and cooling meat under crystallizer Width of plate slab, calculated by mouth width degree (A)=cold conditions width of plate slab × 1.013 under crystallizer;Crystallizer leptoprosopy taper takes Certainly in width of plate slab and crystallizer operation condition, for new crystallizer, 1% width of plate slab is adjusted on crystallizer bottom edge, i.e., Taper is 1%;
Slab fan-shaped section and round billet section sequence correspond, and are divided into 5 fan-shaped sections, each section of inlet and outlet size Control such as table 1
