Below in conjunction with drawings and the specific embodiments the utility model is described in further details.
Embodiment
Consult shown in Figure 1ly, the utility model vacuum annealing furnace heating unit comprises body of heater and built-in flue 2, and flue is built-in with heating unit device 1.
Improvement of the present utility model is: at first, adopted segmentation independence temperature control, the well heater of the mutual loose joint of the many groups of described heating unit device 1 usefulness is formed, order is installed in the flue, is easy to installation and maintenance and replacing.Be provided with one group of thermoscreen 3 between well heater 1 and flue 2 inwalls, adopt 4-6 layer heat-resistance stainless steel thermoscreen suitable, adopt 5 layers among the embodiment shown in the figure.Under the prerequisite that leaves an amount of thermal elongation leeway, reduce distance between each well heater, to reduce the temperature difference of two district's intersections as far as possible.And adopt segmentation independence temperature control, and every group is separate adjustable warm area, every district is equipped with temperature control and temperature measuring unit, has warm galvanic couple in school and interface, conveniently regulating and controlling.
Another improvement of the present utility model is: the heating member of heating unit device 1 adopts Cr20Ni80 resistive heating band, and its resistivity is higher, good processability, and hot strength is good, quick heating, energy efficient, with after do not become fragile, long service life has austenite structure, and is nonmagnetic substantially.In addition, every group of resistive heating tep reel becomes annular mouse cage shape (referring to Fig. 2), and the heating area coverage is big, and property is good symmetrically and evenly.When vacuum tightness reaches 1.3 * 10
-2During Pa, resistive heating band 1 is energized heating, makes workpiece reach annealing temperature.Every group of resistive heating tep reel of the utility model heating unit becomes the axial length of annular mouse cage shape suitable with 15～25 meters, and 20 meters is good.Certainly, its length also can be done the adjustment of any way according to the demand of using.
An improvement more of the present utility model is: the burner hearth of horizontal and flue circular concentric, and heating member is evenly distributed, flue can guarantee at vertical diameter to thermally equivalents all ± 2 ℃ furnace temperature uniformity coefficient.Simultaneously, because the circular configuration area of dissipation is little, thermosteresis is less, has improved thermo-efficiency, save energy.Flue 2 can two-layerly be made of inside and outside, guarantees that heat resisting temperature is at 1100 ℃.
Described heating unit 1(is the resistive heating band) be fixed on flue 2 inwalls with porcelain spare 5 by insulation, this insulation is adopted high-quality 99% alumina ceramics spare with porcelain spare 5, has anti-depositional texture, guarantees that insulation component can long-term stable operation.
Described anti-depositional texture can be referring to shown in Figure 3, and insulation is fixedlyed connected with resistive heating band 1 by porcelain seat 6 with porcelain spare 5.Be because: under the vacuum environment and the condition of high temperature, the chemical ingredients that volatilizes easily is plated in insulation with on the porcelain spare, causes short circuit, so the porcelain seat 6 of this anti-depositional texture is equivalent to can effectively prevent the generation of short circuit phenomenon for the heating zone has covered a big hat.
