Continuous casting flow control molding casting siphon spout device
Technical field
The utility model belongs to steel industry continuous casting flow control molding casting application field, more particularly to a kind of simply high The continuous casting flow control molding casting siphon spout device of effect.
Background technology
Continuous casting is the technical process for molten steel being cast into solid strand, and molten steel flows into middle from the long nozzle of ladle bottom Bag, then the submersed nozzle from tundish downstream is continuously injected into water mold, is cooled into definite shape and thickness Green shell, from crystallizer outlet pull straight, form strand after being solidified through water-spraying control.In the 1950s, being used as steel work The steel Development of Continuous Casting Technique of industry revolution mark gets up, compared with conventional molding techniques, and there is continuous casting metal recovery rate height, energy to disappear The low advantage of consumption, the realization of sequence casting more simplifies steel making working procedure, and production efficiency is improved.
In casting process, flowing of the molten steel in tundish and crystallizer is a kind of multiphase flow and non-stationary flow, while companion With a large amount of fine motions being mingled with and the heat transfer of molten steel, tundish and crystallizer be then by submersed nozzle and stopper or Sliding plate flow-control system connectivity is with blocking.Traditional submersed nozzle is arranged on tundish bottom, and molten steel leans on molten steel in tundish Static pressure flows into tundish bottom outlet, through submersed nozzle molding casting, injects in crystallizer.The research of current people is main The research concentrated in terms of material, shape, structure, additional device and the function of submersed nozzle, but be all confined to be arranged on The mode of tundish bottom, i.e. tundish, submersed nozzle, crystallizer are the vertical arrangement arrangements of upper, middle and lower.To existing company The case study for casting system equipment arrangement finds that the arrangement podium level of upper, middle and lower is big, and molten steel impact can be strong, system energy Consumption is high.
During traditional continuous casting flow control molding casting, there is whirlpool to conflux at middle water containing opening, molten steel stream in submersed nozzle Fast high, impact is big, makes Mold flow field complicated.
Utility model content
In order to solve prior art presence go out many defects, the purpose of this utility model is to provide a kind of casting process molten steel The siphon spout device of molding casting, the device improves traditional continuous casting system, and continuous casting is carried out using the device The continuous casting platform total height in workshop can be reduced, it is adaptable to the technological improvement of existing steel plant's continuous casting process.
Realize that above-mentioned purpose uses following technical scheme:
A kind of siphon spout device, the siphon mouth of a river is arranged between molten steel crystallizer and tundish, including siphon piping, is taken out Inhale device, flow control slide plate, it is characterised in that described siphon piping is divided into tedge, horizontal inclined tube and down-comer, tedge, Horizontal inclined tube and down-comer are closely connected in middle containment wall, tedge bottom insertion tundish successively, the water of horizontal inclined tube Flat angle is 30 ~ 45 degree, the bottom insertion crystallizer of down-comer;Flow control slide plate is arranged on position on the upper side in the middle part of down-comer, is located at Between aspirator and crystallizer molten steel liquid level;Aspirator is that molten steel caches bag, and molten steel caching bag sets up two tube heads, one separately It is connected with down-comer top, connection aspiration pump in other end is provided with control valve between molten steel caching bag and down-comer;Described Tundish, the siphon mouth of a river, crystallizer are arranged according to the horizontal pattern of left, center, right.
Further, described tedge, horizontal inclined tube are identical with down-comer specification, and material is identical.
Further, rise tube inlet close to tundish bottom and plane of inlet is higher than crystallizer molten steel liquid when stabilization is poured into a mould Face.
Further, flow control slide plate is the sliding panel with open and close function.
Compared with prior art, the utility model uses tundish, submersed nozzle, the horizontal cloth of crystallizer " left, center, right " Pattern is put, continuous casting system is improved, compared to traditional continuous casting, it is possible to decrease the continuous casting platform total height in workshop.The utility model The siphon mouth of a river of setting breaches conventional thought, and during its flow control molding casting, tundish confluxes without whirlpool, and in the mouth of a river Molten steel flow velocity is low.Siphon mouth of a river down-comer and crystallizer convenience, accurate centering, can on-line control alignment degree, and without moving at any time Dynamic tundish;Can the mouth of a river of on-line control siphon at any time insert the depth of crystallizer, improve Mold flow field, adjust slag line Attack sites.
