Description
Technical field
The utility model relates to smelts continuous casting field, refers in particular to a kind of for establishing protective refractory structure in tundish splayed configuration passage eddy-current heating and the defensive tundish of purifier.
Background technology
Tundish splayed configuration passage eddy-current heating and purifier not only can effective compensation Metal in Tundish temperature drop, can effectively reduce particularly small-sized field trash of total oxygen content and non-metallic inclusion simultaneously, improve Cleanliness of Molten Steel, yet its core component induction coil is mounted in tundish, operating temperature is high, for avoiding induction coil to contact liquid molten steel, must adopt refractory material effectively to protect it, need reliable refractory material safeguard structure reasonable in design for this reason, guarantee device security stable operation.Because the tundish limited space after induction coil is installed, just require refractory material or fireproof construction layout to answer compact, package space in the middle of as far as possible not taking; And refractory material needs one side contact molten steel, cold and hot contraction easily causes refractory material cracking in online baking or use procedure and causes bleed-out accident.
Summary of the invention
The purpose of this utility model is for the shortcoming existing in background technology and problem improvement and bring new ideas in addition, provide a kind of according to tundish structure feature and tundish refractory material handling characteristics rational deployment, can effectively to induction coil, protect, guarantee to establish protective refractory structure in the tundish of the safe and reliable stable operation of tundish induction heating equipment.
The technical solution of the utility model is a kind of protective refractory structure that is arranged at tundish inside of structure, for cutting off the passage eddy-current heating being installed in tundish, contact with high-temperature molten steel in bag with the induction coil of purifier, it is comprised of prefabricated component and pouring piece, wherein prefabricated component comprises grooved briquetting, pouring piece comprises protective sleeve permanent liner, described protective sleeve permanent liner is U-shaped structure, be arranged at outside the steel bushing that induction coil is installed, grooved briquetting splices the U-shaped openend in protective sleeve permanent liner, U-shaped protective refractory structure with protective sleeve permanent liner composition induction coil.
Advantage of the present utility model and beneficial effect:
The resistance to molten steel of the utility model structure washes away, corrodes, good thermal shock stability, and easy disassembly, meets the requirement of quick-replaceable tundish.Fireproof construction adopts reliable and stable " U " type protection Design simultaneously, can the stable operation of safeguard protection tundish induction heater.

The specific embodiment
From Fig. 1 to 6; the utility model is arranged at tundish 3 inside; for cutting off the passage eddy-current heating being installed in tundish 3, contact with high-temperature molten steel in bag with the induction coil of purifier; it is comprised of prefabricated component and pouring piece; its prefabricated component comprises grooved briquetting 1; pouring piece comprises protective sleeve permanent liner 2; described protective sleeve permanent liner 2 for U-shaped structure, be arranged at outside the steel bushing 4 that induction coil is installed, grooved briquetting 1 splices U-shaped openend in protective sleeve permanent liner 2, forms the U-shaped protective refractory structure of induction coils with protective sleeve permanent liner 2.
Grooved briquetting 1 described in the utility model is seamless spliced with protective sleeve permanent liner 2, and wherein protective sleeve permanent liner 2 adopts the mode of cast-in-site to form.Described grooved briquetting 1 is the block structure of both sides band projection revetment 11, and the upper surface of the upper surface of projection revetment 11 and protective sleeve permanent liner 2 is in same level.Described protective sleeve permanent liner 2 is located at outside steel bushing 4, semi-circular section 21 and square section 22, consists of.Between described protective sleeve permanent liner 2 and steel bushing 4, be provided with cushion 5.
The utility model adopts " U " type safeguard structure of safety and stability, is arranged on tundish 3 inside, and coil is played to protective action.Pouring piece protective sleeve permanent liner 2 is arranged in steel bushing 4(steel bushing and is used for placing induction coil) outside, its one end is square, one end is semi-circular shape in addition, between protective sleeve permanent liner 2 and steel bushing 4, cushion 5 is set.Prefabricated component grooved briquetting 1 carries out seamless spliced with the square one end of protective sleeve permanent liner 2; 1 liang of lateral process of its grooved briquetting be the revetment of projection, revetment upper surface and protective sleeve permanent liner 2 upper surfaces are positioned at same plane.Protective sleeve permanent liner 2 adopts cast-in-place shaping, and grooved briquetting 1 adopts prefabricated component form.
The utility model protective refractory structure, can be good at inductor to play protective action, and make Metal in Tundish even flow field, in actual use procedure, the part of fireproof construction does not occur that any cracking oozes steel phenomenon, has guaranteed the safe and stable operation of equipment.
Embodiment described in the utility model is only the description that preferred embodiment of the present utility model is carried out; not the utility model design and scope are limited; do not departing under the prerequisite of the utility model design philosophy; various modification and improvement that in this area, engineers and technicians make the technical solution of the utility model; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection, is all documented in claims.
