Abstract
The invention discloses a core type elevator furnace, and specifically relates to the technical field of thermal treatment processing equipment. The core type elevator furnace comprises an outer cover (1), and a base (5); the core type elevator furnace further comprises a central heating stick (4); the central heating stick (4) is fixed in the center of the base (5). The core type elevator furnace employs the central and peripheral concentric circles to heat synchronously, with the outer cover being a main heat source and the central heating stick being a supplementary heat source. Saw blades are distributed in a circular zone between the inner heat source and the outer heat source, thus the saw blades are equidistantly located from the heat sources, accordingly the heat radiation efficiency is high, the heat transmission efficiency is high, the heating speed is fast, and the hearth temperature is uniform. Heating by such manners, the phenomenon of over-heating the outer sides whereas under-heating the inner sides of the saw blades can be avoided effectively. Due to the fact that the temperature is uniform, the product is uniformly heated, the alloying degree of the cutter head is high, and the quality and performance of the product are increased.
Description
Technical field
The invention belongs to heat treatment process equipment technical field, be specifically related to a kind of core type clock hood type furnace.
Background technology
The thermal source of current domestic diamond tool required in manufacturing process is resistance furnace, shaft furnace, continuous oven, clock hood type furnace, and what be wherein widely used is continuous oven and clock hood type furnace.Clock hood type furnace adopts outer silk of sitting around a fire to heat, and saw blade is gathered in zone line with the form of circle, and distribution allows the saw blade in central area effectively can not accept thermal source like this, and the saw blade of periphery receives a large amount of thermal source, causes sintering unbalanced, crosses endobiosis outside occurring.In order to the saw blade of central area sintering can be allowed ripe, just need heat time of more growing and temperature retention time, the long heat time causes the waste of electric energy, and production efficiency is low.
The defect such as slow for clock hood type furnace thermal conduction rate, the heat time is long, production efficiency is low, fault rate is high.Domestic and international colleague has descended certain time in the improvement of clock hood type furnace, and Korea S adopts the oblique method of hydrogen, but effect is unsatisfactory, just makes the protective effect of protective gas to saw blade strengthen to some extent to a certain extent; Domestic pharmaceutical industry adopts the rotary clock hood type furnace of base, effectively can improve the protection of protective gas to saw blade, but can not shorten intensification, temperature retention time.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind ofly to enhance productivity, the core type clock hood type furnace of energy-conservation, low fault.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of core type clock hood type furnace, comprises outer cover, base, also comprises center heating rod; Described center heating rod is fixed on described base center.
Further technical scheme is, described center heating rod and outer cover and the direct vertical connection of base.
Further technical scheme is, described center heating rod comprises Elema, inner bag, refractory fixture, asbestos; Described Elema is fixed in inner bag through refractory fixture; Described asbestos are filled in inner bag root.
Further technical scheme is, described center heating rod adopts 3-6 single u-shaped Elema as heating source, and power is 10-30KW.
Further technical scheme is, on described core type clock hood type furnace outer cover inwall, symmetry arrangement has heating element heater, and power is 30-50KW.
Further technical scheme is, the middle, top of described outer cover is provided with hanger.
The beneficial effect adopting technique scheme to produce is:
Core type clock hood type furnace adopts center and external concentric to justify to heat simultaneously, outer cover as main heating source, center heating rod thermal source as a supplement.Saw blade is distributed in the circle ring area in the middle of interior external heat source, and such putting makes saw blade distance heating source comparatively even, and radiation efficiency is high, and heat conduction efficiency is high, and programming rate is fast, and fire box temperature is balanced.Adopt this mode of heating effectively can avoid phenomenon raw in the outer mistake of saw blade, because temperature equalization is good, product is heated evenly, and the alloying level of cutter head is high, improves quality and the performance of product.

Detailed description of the invention
In order to deepen understanding of the present invention, be described in further detail the present invention below in conjunction with drawings and Examples, this embodiment, only for explaining the present invention, not forming protection domain and limiting.
A kind of core type clock hood type furnace that the present embodiment provides, comprises symmetry arrangement on inwall by the outer cover 1 of heating element heater 3, base 5, the center heating rod 4 that is made up of 3-6 single u-shaped Elema 8, inner bag 6, refractory fixture 7, asbestos 9; Center heating rod 4 is fixed on the center of base 5.Center heating rod 4 and outer cover 1 vertical connection direct with base 5.U-shaped Elema 8 is fixed in inner bag 6 through refractory fixture 7; Asbestos 9 are filled in inner bag 6 root.Center heating rod power is 10-30KW.Core type clock hood type furnace outer cover 1 power is 30-50KW.The middle, top of outer cover 1 is provided with the hanger 2 being beneficial to suspention.
The beneficial effect of the present embodiment is: the present invention can reach reduction production cost, the effect that economize energy consumes, and shortens sintering, temperature retention time about 50%, enhances productivity; And the present invention can make saw blade be heated evenly, contribute to improving saw blade tip with evolution degree, improve the quality of saw blade, improve the life-span 5-15% of saw blade.
