Abstract
The invention provides a split insulated tundish structure, which can effectively solve the problem that the traditional tundish shell is deformed by heating due to induced current, thus being not suitable for an electromagnetic induction heating device. The structure comprises an impact zone tundish body and a pouring zone tundish body; two flowing steel passages are embedded at the bottom of a transition tundish body between the impact zone tundish body and the pouring zone tundish body; a non-magnetic stainless steel sleeve is arranged in the transition tundish body; and one end of the electromagnetic induction heating device passes through the transition tundish body and is arranged in the non-magnetic stainless steel sleeve. The structure is characterized in that: both the transition tundish body and the non-magnetic stainless steel sleeve comprise a front part and a rear part; the front and rear parts of the transition tundish body are integrally connected with the impact zone tundish body and the pouring zone tundish body respectively; and an insulating layer is clamped between the transition tundish body of the front and rear parts and the non-magnetic stainless steel sleeve, and the transition tundish body and the non-magnetic stainless steel sleeve are connected and fixed through a flange.
Description
Technical field
The present invention relates to continuous casting electromagnetism technical field of smelting, be specially split type insulation pans structure.
Background technology
Conventional pans housing is an overall structure; When using electromagnetic induction heater; The alternating flux that induction heater excites with molten steel and the pans housing of iron core linkage in produce induced-current, thereby this induced-current produces Joule heat heating molten steel in the molten steel in ladle canal, in the pans housing, also produce Joule heat simultaneously; Consequent tank body Joule heat can cause the tank body temperature distortion, thereby conventional pans can't be useful in the occasion of using electromagnetic induction heater.
Summary of the invention
To the problems referred to above, the invention provides split type insulation pans structure, it can effectively solve traditional pans housing produces the inapplicable electromagnetic induction heater of tank body temperature distortion because of induced-current problem.
Its technical scheme is such; A kind of pans structure; It comprises impact zone tank body, pouring area tank body; Transition tank base between said impact zone tank body and the said pouring area tank body is embedded with two ladle canals; Non-magnetic stainless steel sleeve is installed in said transition tank body, and an end of electromagnetic induction heater passes said transition tank body and is installed in the said non-magnetic stainless steel sleeve, it is characterized in that: two parts before and after said transition tank body and said non-magnetic stainless steel sleeve include; The forward and backward part of said transition tank body is connected with said impact zone tank body, said pouring area tank body integral body respectively, has clamped insulating barrier between said forward and backward two-part transition tank body, the non-magnetic stainless steel sleeve and has connected fixing through flange.
It is further characterized in that: pass through bolt between said flange and the insulating barrier; Said bolt outer setting has insulation sleeve, is provided with insulation spacer between said bolt and the said flange; Clamped said insulating barrier between said non-magnetic stainless steel sleeve and said each contact-making surface of transition tank body.
Split type insulation pans structure of the present invention; It has clamped insulation board with the coupling flange that whole pans structure is divided between forward and backward two parts and two parts; Forward and backward two-part connecting bolt is outside, between bolt and the tank body, be provided with insulating barrier between non-magnetic stainless steel sleeve and the tank body; Thereby stopped induced-current and in the pans housing, produced the closed-loop path, effectively avoided the temperature distortion problem of tank body.
Description of drawings
Fig. 1 is a pans structure plan structure sketch map of the present invention;
Fig. 2 connects local enlarged diagram for the bolt of Fig. 1.
The specific embodiment
See Fig. 1, Fig. 2; New structure of the present invention comprises impact zone tank body 1, pouring area tank body 2; Being divided into two parts by transition tank body 3 between molten steel impact zone tank body 1 and the pouring molten steel district tank body 2 connects through flange 10; Non-magnetic stainless steel sleeve 4 is installed in transition tank body 3; The end peace that electromagnetic induction adds heater 5 is passed transition tank body 3 and is loaded in the non-magnetic stainless steel sleeve 4, is embedded with two ladle canals in transition tank body 3 bottoms, two parts before and after transition tank body 3 includes with non-magnetic stainless steel sleeve 4; The forward and backward part of transition tank body is connected with impact zone tank body 1, pouring area tank body 2 integral body respectively, has clamped insulating barrier 6 between forward and backward two-part transition tank body, the non-magnetic stainless steel sleeve and has connected fixing through flange 10, bolt 7.Bolt 7 outer setting have insulation sleeve 8, are provided with insulation spacer 9 between bolt 7 and the flange 10; Clamped insulating barrier 6 between non-magnetic stainless steel sleeve 4 and each contact-making surface of transition tank body.
Specific embodiment of the present invention only is the description to preferred implementation of the present invention; All structures that connects through insulating after middle tank body is separated solve former whole tank structure and produce the innovation and creation of tank body temperature distortion problem because of receiving induced-current, all should fall into protection scope of the present invention.
