Description
Technical field
The utility model belongs to metallurgical machinery equipment, particularly relates to one and is applicable to square-round billet continuous casting machine strand two cold air mist spray device.
Background technology
The main point two-step cooling mode of present metallurgical square-round billet continuous casting machine cooling, once cools (be commonly called as " one cold ") and refers to crystallizer foot roll section spraying cooling; Cooling twice (be commonly called as " two cold ") refers to that in the indoor fan-shaped section of caster two cold, fixing spray equipment cools, two cold according to technique need can divide 2-3 section again, according to different steel grade, simultaneously or the cold different spray section of fractional open two, the cooling effect required for realization.Current for obtaining good slab cooling effect, generally aerosol is all adopted to cool, cooling effect is better, slightly improved than previously using direct injection nozzle, most of existing conticaster spray equipment arrangement of nozzles is all generally that on conticaster arc direction, same cross section is angularly arranged, greatly improved although cooling effect has more previously had, but it is still even not at the diverse location cooling effect of continuous casting billet, as: a kind of round billet continuous casting di-cold spray nozzle arrangement designed in patent No. ZL200720035125.3 is by 1 six side's distributor, 6 groups of spray bars, every root spray bar is furnished with 6 row's nozzles, nozzle angle is 60 °, identical owing to often organizing spray bar top nozzle vertical direction spacing, major defect is, arrange nozzle location up and down identical, do not misplace Spiral distribution, spray has dead band and leak source, the overall cooling effect of strand is even not, affect slab quality, or can the macro defects such as center porosity be produced, impact is had on production special steel quality.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of conticaster spray washing device and puts, adopt staggered, the spiral installation form of aerial fog nozzle, the cooling of strand surrounding evenly, intensity Discrete control, can control separately according to the different steel grade of production, effectively reduce the casting blank defects such as the center porosity of strand, make the cooling homogenising of strand, effectively can improve the quality of strand, dismounting is simultaneously easy, decreases the amount of labour of plant maintenance personnel.
For realizing above-mentioned technical purpose, a kind of conticaster spray washing of the utility model device, it comprises cubic aerosol dispenser and some spray bars, described cubic aerosol dispenser is rectangular, some spray bar installing racks are fixedly installed in cubic aerosol dispenser surrounding, spray bar is connected with cubic aerosol dispenser by spray bar installing rack, described spray bar comprises spray bar body, tube connector and nozzle, spray bar is communicated with cubic aerosol dispenser by tube connector, each spray bar is arranged six row's nozzles, often arrange nozzle and stagger 25 °, often arrange the spacing that injector spacing is the arc radius 1 ° of conticaster, nozzle location on described spray bar is all being inscribed within the circular periphery on the long limit of rectangle with the center of rectangle four directions aerosol dispenser for the center of circle, described spray bar arranges even number root.
For ensureing that cooling quality considers cubic aerosol dispenser space constraint simultaneously, described spray bar arranges four, the nozzle be arranged on the spray bar on the long limit of aerosol dispenser, rectangle four directions is symmetrical arranged with rectangular centre between two, the nozzle be arranged on the spray bar on the aerosol dispenser minor face of rectangle four directions is symmetrical arranged with rectangular centre between two, nozzle on four spray bars is crisscross arranged, and entirety twist.
Due in use procedure, produced on-site rhythm is very fast, spray bar or nozzle fragile, maintenance difficult, for convenience of dismounting, by steady pin, dismountable and cubic aerosol dispenser is connected described spray bar.
During installation, first on conticaster canned paragraph, fix cubic aerosol dispenser, keep cubic aerosol dispenser with conticaster outer arc tangent line at right angle setting; Again namely four spray bars are installed to the surrounding of tetragonal body aerosol dispenser: inner arc, outer arc, the south, each one of north, with steady pin pin locked, finally at each spray bar arm place, aerial fog nozzle is installed, connects compressed air, cooling water medium pipeline, namely complete whole installation processes.
When changing different section for different square-round billet continuous casting machine, tetragonal body aerosol dispenser is designed to not change equally, changes spray bar as long as each.
The utility model structure is simple, easy to use, adopt staggered, the spiral installation form of aerial fog nozzle, the cooling of strand surrounding evenly, intensity Discrete control, can control separately according to the different steel grade of production, effectively reduce the casting blank defects such as the center porosity of strand, make the cooling homogenising of strand, effectively improve the quality of strand, dismounting is simultaneously easy, decreases the amount of labour of plant maintenance personnel.
