Abstract
The utility model relates to a heat treating furnace, particularly a round full-fiber well type furnace for solving the technical problems of excessive softness, difficult installation of electrothermal elements, uneven heat radiation in a furnace inner cavity and separation manufacture of a furnace casing of the existing full-fiber furnace wall. The round full-fiber well type furnace comprises a furnace casing and a heating element fixed to a fiber furnace wall, wherein the furnace casing forms a circular cylinder shape which is molded in one time. The fiber furnace wall is built by compressed fiber bricks and compression amount is greater than 40%. The compressed fiber bricks are fixed to the furnace wall by a fixing press plate and heat-resisting pull ribs. The electrothermal element is fixed to the full-fiber furnace wall with high intensity by a ceramic bolt and a pad and forms a wave and belt shape. The utility model is mainly used for heat treatment for shaft class components.
Description
Technical field: the utility model relates to a kind of heat treatment furnace, the full fiber pit furnace of particularly a kind of circle.
Background technology: full fiber heat treatment furnace has high-quality and efficient, low consumption, long-lived flexible characteristic, but because full fiber furnace wall is too soft, can't electrical heating element be installed and become the bottleneck that full fiber stove develops always, the volution nichrome wire that full fiber pit furnace in the past adopts can't be fixed on the fiber, can only be fixed on (by one group of S shape pottery hook) on the furnace shell to ceramic rod earlier, because ceramic rod can not be crooked, furnace shell can only make six blocks of plates earlier, and then be spliced into integral body, again the nichrome wire that is enclosed within on the ceramic rod is put on the S shape pottery hook, often ceramic rod is broken when nichrome wire expands with heat and contract with cold and caused the nichrome wire short circuit, maintenance is trouble very, the main drawback that exists is as follows: the manufacture method complexity, need make six bodies of heater earlier, be assembled into complete body of heater again, when assembly unit, can damage full fiber body of heater, and need make certain rigid trestle; The stove stopping property is poor, and the fiber compression is also inhomogeneous, and the thermal radiation of stove inner chamber is inhomogeneous; Electrical heating element is fixing not firm, and work-ing life is not long, and the electrical heating element heating efficiency is low.
Summary of the invention: the purpose of this utility model provides a kind of electrical heating element fixation, and heat emissivity coefficient is big, the heating efficiency height, and furnace temperature is even, the circular full fiber pit furnace of long service life.It is too soft to solve existing full fiber furnace wall, electrical heating element can't be installed, the thermal radiation of stove inner chamber is inhomogeneous and furnace shell needs the technical problem of split production.
Technical solution is: circular full fiber pit furnace, comprise furnace shell and the heating unit that is fixed on the fiber furnace wall, furnace shell is that once-forming is cylindric, and the fiber furnace wall is by the brick one-tenth of conpressed fibers, draught is greater than 40%, and the conpressed fibers brick is fixed on the furnace wall with fixation clip, heat-resisting lacing wire.On high-intensity full fiber furnace wall, electrical heating element is the banded electrical heating element of waveform to electrical heating element with ceramic Luo bolt, spacers.
The beneficial effects of the utility model are: circular furnace shell once-forming, and easily manufactured, structure is firm; The refractory fibre good airproof performance is installed, long service life in the circular furnace shell; Fixed, the safety of electrical heating element, the heating efficiency height; The banded electrical heating element of waveform is compared with helical electric heating element, and it is big to have a heat emissivity coefficient, the thermo-efficiency height, and furnace temperature is even, the characteristics of long service life; The interior thermal radiation of stove is even, helps improving the homogeneity of furnace temperature; Refractory fibre and rolled steel dosage reduce.
Description of drawings:
Accompanying drawing is the utility model structural representation
Among the figure: the 1-furnace shell; 2-fiber furnace wall; The 3-ceramic screw; The 4-ceramic gasket; 5-waveform resistive band; The heat-resisting lacing wire of 6-; The 7-fixation clip.
Embodiment:, furnace shell 1 is rolled into drum, once-forming earlier with reference to accompanying drawing, again the good band fixation clip 7 of compression, fiber furnace wall 2 fix in position of heat-resisting lacing wire 6, fixation clip 7 spots weld on the furnace shell 1, and electrical heating element is the banded electrical heating element of waveform, adopts 0Cr27Al7Mo2 waveform resistive band 5, directly be fixed on the fiber furnace wall with ceramic screw 3 and ceramic gasket 4, not only convenient but also firm, heat emissivity coefficient is big, the heating efficiency height, furnace temperature is even, long service life.
