Description
Technical field
The utility model relates to a kind of device preventing from slab caster mould from opening watering splash, belongs to steel-making continuous casting technical field.
Background technology
Crystallizer is as the core of conticaster, and its effect is the base shell by forcing cooling to make the high-temperature molten steel continued through be condensed into required form and certain uniform thickness, for strand creates conditions solidifying completely of secondary cooling zone.The crystallizer of slab caster is primarily of 2 pieces of wide copper coins (interior outer arc plate) and 2 pieces of narrow copper plate (left side plate) compositions, and wherein 2 narrow copper plates are clipped between 2 wide copper coins, are obtained the shape of required casting blank section by the position adjusting narrow copper plate; For ensureing the continuity of casting, the end of crystallizer is " false bottom ", opens before watering and is first sealed by crystallizer end opening with dummy bar head, then sprinkles nail bits and cold burden, and the head base opening just one-step forming after watering starting slowly draws pull-out crystallizer by dummy bar head, then pulls out through secondary cooling zone.
In continuous casting production process, open when watering at every turn, molten steel flow in crystallizer from the tap hole of submersed nozzle, because the tap hole of submersed nozzle and crystalliser feet exist drop, high-temperature molten steel is considered to be worth doing with nail simultaneously, cold burden, there is the temperature difference in copper plate of crystallizer, there is fierce rolling after high-temperature molten steel flows out and splash, the molten steel splashed may spatter to crystallizer flange suitable for reading or form cold steel in angle seam, can be connected with base shell when cold steel on flange is serious, may cause and hang steel bleed-out accident, cold steel in angle seam can cause scuffing to initial solidification shell, scabbing in bight to cause strand to occur, for solving problems, Chinese patent " plate slab crystallizer is opened and watered antisplash device " (patent No. 201120472389.1) adopts wooden slag trap to carry out opening and water molten steel antisplash, its weak point for this splash-back be one block of straight plate, if baffle plate and Wide-surface copper plate of crystallizer card is too tight, not too convenient during taking-up, if when leaving gap, splashproof effect is not ideal, if moreover wooden baffle plate is opened when watering and is immersed in molten steel, also can produce splash.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of device preventing from slab caster mould from opening watering splash, this device can reduce plate slab crystallizer and open the molten steel splash in the process of watering, prevent crystallizer flange and angle seam place from tying cold steel, improve slab quality and copper plate of crystallizer service life, have simultaneously and be easy to operate, be convenient to the advantage safeguarded.
The technical scheme solved the problems of the technologies described above is:
Prevent from slab caster mould from opening watering the device of splash, it comprises the crystallizer be made up of two pieces of wide copper coins be oppositely arranged and two pieces of narrow copper plates be oppositely arranged, two pieces of narrow copper plates are folded between two pieces of wide copper coins, its improvements are: between the narrow copper plate of the crystallizer left and right sides, set up 2 anti-splash devices, anti-splash device is made up of the side plate on 1 piece of base plate both sides relative to being individually fixed in base plate, its cross section is isosceles trapezoid, the cavity that 2 anti-splash devices and 2 pieces of wide copper coins form a up/down perforation, left and right is closed.
The above-mentioned device preventing from slab caster mould from opening watering splash, the base plate of described anti-splash device and side plate are steel rectangular slab, baseplate width is less than narrow face copper plate of crystallizer width, the angle of biside plate and base plate is 95 ° ~ 100 °, and biside plate offsets away from the limit be connected with base plate and Wide-surface copper plate of crystallizer inwall.
The above-mentioned device preventing from slab caster mould from opening watering splash, described anti-splash device also comprises the handle being fixed on base plate/side plate top.
The beneficial effects of the utility model are:
When using the utility model, anti-splash device is inserted between crystallizer two pieces of narrow copper plates, make 2 anti-splash devices staggered relatively in the both sides of submersed nozzle, because anti-splash device biside plate offsets away from the limit be connected with base plate and Wide-surface copper plate of crystallizer inwall, so 2 anti-splash devices and Wide-surface copper plate of crystallizer form a up/down perforation, the cavity that left and right is closed, hold the molten steel flowed out from submersed nozzle in the process of watering and only understand splash to base plate or side plate, molten steel can not be there is and spatter the situation forming cold steel to crystallizer flange or angle seam, successfully solve slab caster and open the problem that the crystallizer flange that causes due to molten steel splash in the process of watering and angle seam hang steel, improve slab quality, decrease and hang steel bleed-out accident, ensure that the direct motion of conticaster, the utility model structure is simple, easy to use, is suitable for promoting in the fourplatemold of all slab casters.
