Description
Technical field
The utility model relates to the full enclosed intermediate frequency furnace of a kind of silicon steel sheet.
Background technology
Present middle frequency furnace, adopts silicon steel sheet (yoke) to be fixed on around body of heater usually, and the magnetic line of force is transmitted in its effect, and constraint induction coil leakage field, to external diffusion, improves eddy-current heating efficiency.In addition, as magnetic masking layer, reduce the heating of the metal structures such as peripheral grate, also play the effect of reinforcing induction coil, silicon steel sheet (yoke) generally surrounds the area of body of heater coil 60%, and the thermal efficiency is about 85%.
Utility model content
The purpose of this utility model is to provide the middle frequency furnace of the full enclosed of a kind of silicon steel sheet, the leakage field phenomenon of basic elimination intermediate frequency furnace, improves furnace heat efficiency, shortens steel alloy smelting time, make furnace heat efficiency reach more than 95%, smelting time shortens to about 80% of existing middle frequency furnace.
To achieve these goals, the utility model adopts following technical scheme.
The full enclosed intermediate frequency furnace of a kind of silicon steel sheet, comprises upper cover plate, silicon steel sheet (yoke), body of heater, staking, set bolt, silicon steel sheet holder, body of heater seat, bottom plate, induction coil; Described staking is fixed between upper cover plate and bottom plate, body of heater seat is fixed on bottom plate, body of heater is fixed on body of heater seat, the excircle of described body of heater is fixed with some spaced silicon steel sheets, described silicon steel sheet is fixed on silicon steel sheet holder, silicon steel sheet holder is fixed on staking by set bolt, and described induction coil is fixed between silicon steel sheet and body of heater.
As further improvement of the utility model, between described silicon steel sheet, be also provided with cooling water pipe, the cooling water pipe between yoke, through water flowing cooling yoke, ensure to allow yoke be in normal temperature state, avoid temperature to raise and produce distortion.
The beneficial effects of the utility model: intermediate frequency (IF) smelting electric furnace of the present utility model adopts the full enclosed structure of silicon steel sheet, effectively the magnetic line of force is gathered in molten bath, prevents furnace shell from generating heat, improve system effectiveness; Stable performance also gives coil to support reliably simultaneously, improves body of heater bulk strength.Silicon steel sheet assembling have employed arc stacking technique, and be convenient to compress, leakage field is few.More be adjacent to induction coil, improve magnetic flux trend, eliminate iron core at the local flux saturated phenomenon of seam crossing, reduce the open circuit loss of iron core, no-load current, make full use of the magnetic conductive area of silicon steel sheet, reduce the possibility of medium frequency induction melting furnace furnace shell local pyrexia.

Fig. 2 is that the utility model removes upper cover plate top view.
Wherein, 1, upper cover plate; 2, silicon steel sheet; 3, body of heater; 4, staking; 5, set bolt; 6, silicon steel sheet holder; 7, body of heater seat; 8, bottom plate; 9, induction coil; 10, cooling water pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1-2, the full enclosed intermediate frequency furnace of a kind of silicon steel sheet, comprises upper cover plate 1, silicon steel sheet 2, body of heater 3, staking 4, set bolt 5, silicon steel sheet holder 6, body of heater seat 7, bottom plate 8, induction coil 9; Described staking 4 is fixed between upper cover plate 1 and bottom plate 8, body of heater seat 7 is fixed on bottom plate 8, body of heater 3 is fixed on body of heater seat 7, the excircle of described body of heater 3 is fixed with some spaced silicon steel sheets 2, described silicon steel sheet 2 is fixed on silicon steel sheet holder 6, silicon steel sheet holder 6 is fixed on staking 4 by set bolt 5, and described induction coil 9 is fixed between silicon steel sheet 2 and body of heater 3, is also provided with cooling water pipe 10 between described silicon steel sheet 2.
The silicon steel sheet of the present embodiment entirely surrounds structure and effectively the magnetic line of force that coil produces is gathered in molten bath, improves eddy-current heating efficiency, makes furnace heat efficiency reach more than 95%.Silicon steel sheet entirely surrounds structure and substantially eliminates intermediate frequency furnace leakage field phenomenon, improves magnetic flux trend, reduces the possibility of furnace shell local pyrexia.
Through test, embodiment improves labor productivity, smelting time shortens 1/4 than general purpose electric stove, and body of heater intensity is high, and body of heater improves more than 30% service life.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
