Abstract
The invention relates to a continuous casting electromagnetic refine and heating device, in particular to a bypass dual-channel electromagnetic refine and heating device for tundish. The device comprises a tundish, a package sprue, a curved channel, and an induction heater around the curved channel, wherein, the curved channel is arranged at both sides of a chamber of the package sprue and connected with a package injection chamber and a tundish casting chamber; the induction heater is arranged around the curved channel with a iron core. The device is externally heated by the tundish to make up the heat loss during casting, thereby realizing the thermostatic casting at low superheat and pinching the molten steel through the channel, which can extract the impurities, oxygen and the like from the molten steel so as to promote the quality of the surface and the interior of the continuous cast. The device has the advantages of long channel, large heating power, high internal-cooling efficiency and small heating device, applicable to the technical reconstruction of the tundish in particular to the prior tundish, and can wholly mount and dismount and conveniently maintain.
Description
Technical field
The present invention relates to continuous casting electromagnetism refining heater, refer in particular to a kind of pans bypass type dual-channel electromagnetic refining and heater.
Background technology
The heater of existing continuous casting tundish is made up of following member: it is by two parallel straight line refractory material passage, square shape iron core and unicoils, the heater that protective jacket of the square no end, air cooling system are formed; Each member connects in the following manner or makes up: whole device is installed in pans and big centre of wrapping inlet; protective sleeve of the square no end is installed in the middle part of the back of pans; the left and right sides at protective sleeve is buried two linear refractory material passages underground near the bottom of pans; the iron core of heater is across the partial shell of protective sleeve and pans; the side that coil is arranged is in protective sleeve, and a side of no coil is outside pans.
Its course of work is: after the coil of heater is fed single-phase alternating current, in the square shape iron core of closure, excite the magnetic flux of alternation, the magnetic flux of alternation just with the molten steel of iron core linkage and pans housing in produce induced-current, this induced-current Joule heat of in passage, inducting in the molten steel, thereby the heating molten steel also also produces Joule heat simultaneously in the pans housing.
It has following deficiency: heating power is limited, device structure is huge, is unfavorable for the transformation of existing pans, is unfavorable for applying.Its reason is: because whole device is installed in pans and big centre of wrapping inlet, cause overall structure huge; Because the structural constraint heat tunnel is shorter; Because unicoil has limited the increase of heating power; Owing to adopted indirect air cooling, not only cooling effectiveness is low but also equipment is also huge.
Summary of the invention
The objective of the invention is to be improved and innovate at the shortcoming that exists in the background technology and problem, a kind of pans bypass type dual-channel electromagnetic refining and heater are provided, the heat tunnel that overcomes above-mentioned prior art is short, heating power is limited, the huge deficiency that is unfavorable for that existing pans are transformed of overall structure, refining of a kind of bypass type dual-channel electromagnetic and heater are provided, it is long that it has heat tunnel, the dual inductor heating power is big, interior cold efficiency height, the heater volume is little, suitable pans are the technological transformation of existing pans particularly, this device energy integral disassembly, assembly, easy to maintenance.
Technical scheme of the present invention is a kind of pans bypass type dual-channel electromagnetic refining of structure and heater, be characterized in comprising: pans, wrap inlet and curved channel greatly, reach the induction heater of installing around curved channel, wherein: curved channel is arranged at the both sides of big bag inlet chamber, and connect big bag flood chamber and basket pouring chamber, the induction heater iron core is around the curved channel setting.
Advantage of the present invention and beneficial effect: this device provides external heat source for pans, thermal losses in the compensation casting process, realize the low superheat-degree constant-temperature casting of casting process, simultaneously the molten steel that flows through passage is carried out constriction, field trash in the molten steel and oxygen etc. are extruded, improved continuous casting billet surface and internal soundness whereby.It has that passage is long, heating power is big, interior cold efficiency height, heater volume are little, and suitable pans are the technological transformation of existing pans particularly, and this device can integral disassembly, assembly, and is easy to maintenance.Bypass type dual-channel electromagnetic of the present invention refining and heater are installed in the both sides of big bag inlet, do not change the basic configuration of pans and the relative position at big bag inlet and each sprue gate basically, are particularly suitable for the technological transformation of existing pans.
