Abstract
The utility model discloses a secondary feeding device of a smelting furnace. The secondary feeding device comprises a heating coil (1), a crucible (2) and a feeding bin. The heating coil (1) is installed around the outer wall of the crucible (2). The feeding bin is movably connected with the crucible (2) through a supporting rod (9), and the feeding bin is composed of a front baffle (3), side baffles (5), a rear baffle (6), an upper cover plate (7) and a lower bottom plate (8). The front baffle (3) is hinged to the upper cover plate (7). The upper cover plate (7), the side baffles (5), the rear baffle (6) and the lower bottom plate (8) are welded. The secondary feeding device is made of common stainless steel plates. Raw materials are cheap, and cost is low. The device is portable and can be disassembled and replaced at any time when not needed or damaged. The size is small, the space, occupied by the secondary feeding device, in the furnace is small, and normal operation of smelting and observation on the liquid level condition will not be hindered.
Description
Technical field
The utility model relates to a kind of feeding device, and specifically a kind of smelting furnace secondary charging device, belongs to metal smelt production technical field.
Background technology
Neodymium iron boron in fusion process due to required raw material types difference, its fusing point is also different, low-melting material first melts, after dystectic material, melt, when first the material of fusing is to last all material fusing, volatilization is many, cause final alloying component segregation, affect the performance indications of final products, melting needs to add additive to improve the coercivity of neodymium iron boron sometimes in addition, because additive belongs to metal dust, must after all material fusing, before cast, add this additive successful, therefore secondary charging device is set in smelting furnace particularly necessary.Traditional smelting furnace secondary charging device is by transmission mechanism, and additive is sent into charging mechanism, adds fashionablely need to open push-pull valve, makes material fall into molten steel.But there is following shortcoming in this device: take up room larger, and handling difficulty, maintenance cost is high, and cost is higher.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of smelting furnace secondary charging device, and volume is little, takies furnace inner space few, convenient disassembly, maintenance cost is low, and cost is low.
To achieve these goals, the utility model is achieved through the following technical solutions: a kind of smelting furnace secondary charging device, comprise heater coil, crucible and feeding chamber, heater coil is installed on the outer wall surrounding of crucible, feeding chamber is flexibly connected with crucible by support bar, described feeding chamber is made up of front apron, side shield, backboard, upper cover plate and lower shoe, and front apron is connected by hinged mode with upper cover plate, between upper cover plate, side shield, backboard and lower shoe, all welds.
Further, described front apron is provided with handle, conveniently in feeding chamber, adds material.
Preferably, described front apron, backboard, side shield, upper cover plate and lower shoe are corrosion resistant plate, not fragile, and cost is low.
Further, described crucible angle of inclination is controlled at 20 °～30 °, and this range of tilt angles can either ensure that material falls, and can avoid again crucible to topple over, and improves processing safety.
The beneficial effects of the utility model: by feeding chamber is set above crucible, in the time that needs feed in raw material, manual rotation crucible is to certain angle, material in feeding chamber slides into front apron downwards by himself gravity, front apron is backed down, material just can vertically fall into crucible completely, and can be made material and do not encountered crucible inwall by the effect of blocking of front apron, and reinforced process operation is simple; This device adopts ordinary stainless steel plate to be made, and raw material are cheap, and cost is low; This device is light, is beneficial to disassembling, assembling and replacing, in the time not needing or damage, can change at any time; This device volume is little, takies furnace inner space few, can and not observe liquid level situation and cause obstruction the normal operating of melting.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model schematic diagram when reinforced.
In figure: 1, heater coil, 2, crucible, 3, front apron, 4, handle, 5, side shield, 6, backboard, 7, upper cover plate, 8, lower shoe, 9, support bar.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, a kind of smelting furnace secondary charging device, comprise heater coil 1, crucible 2 and feeding chamber, heater coil 1 is installed on the outer wall surrounding of crucible 2, feeding chamber is flexibly connected with crucible 2 by support bar 9, described feeding chamber is made up of front apron 3, side shield 5, backboard 6, upper cover plate 7 and lower shoe 8, and front apron 3 is connected by hinged mode with upper cover plate 7, between upper cover plate 7, side shield 5, backboard 6 and lower shoe 8, all welds.
Further, front apron 3 is provided with handle 4, conveniently in feeding chamber, adds material.
Preferably, front apron 3, backboard 6, side shield 5, upper cover plate 7 and lower shoe 8 are corrosion resistant plate, not fragile, and cost is low.
Further, crucible 2 angles of inclination are controlled at 20 °～30 °, and this range of tilt angles can either ensure that material falls, and can avoid again crucible 2 to topple over, and improve processing safety.
Need to carry out secondary charging time, first opening front apron 3 inserts low-melting material or additive in feeding chamber, vacuumize power transmission heating in the time that vacuum reaches technological requirement, now heater coil 1 heats up, raw material in crucible 2 start fusing, after material melts completely, rotate crucible 2, controlling its angle of inclination is 20 °～30 °, as shown in Figure 2; Material in feeding chamber touches by himself gravity and slides into front apron 3 downwards, and front apron 3 is backed down, and material just can vertically fall into crucible 2 completely, and can be made material and do not encountered crucible 2 inwalls by the effect of blocking of front apron 3, simple to operate.
