Abstract
The utility model relates to a vacuum heating rod, which aims at overcoming the technical defect of short service life of the existing silicon carbide rod heating element. The vacuum heating rod consists of a tungsten wire, a vacuum cavity, an alumina ceramic pipe, sealing rings, a vacuum pumping pipe and ferrochromium conducting wire posts and is characterized in that the alumina ceramic pipe is in a tubular structure, both ends of the structure are respectively encapsulated with the ferrochromium conducting wire posts by the sealing rings so that the inside of the alumina ceramic pipe forms a vacuum cavity, and the tungsten wire is encapsulated in the vacuum cavity, wherein the vacuum pumping pipe is pre-arranged on the sealing ring at one end, and the welding sealing is carried out after the vacuum pumping. After the adoption of the structure, the heating source of the tungsten wire is in the vacuum state, so the oxidization is avoided, and the service life is prolonged. Compared with the existing silicon carbide rod heating element, the vacuum heating rod has the advantage that the service life is prolonged by 3 to 5 times.
Description
Technical field
The utility model relates to the heating in vacuum rod that the stove heating is left standstill in a kind of aluminium sheet band casting melting, belongs to the electric heating element field.
Background technology
Leave standstill in the stove the normal Elema that uses as heating element in aluminium sheet band casting melting, Elema is as heating source, and resistance increases gradually under the condition of high temperature, aging flexural deformation, and useful life is short, and be 3～6 months general useful life.
The utility model content
The purpose of this utility model provides a kind of heating in vacuum rod, to overcome existing Elema heater element short technological deficiency in useful life.
For achieving the above object, the technical solution adopted in the utility model is:
Heating in vacuum rod described in the utility model is made of tungsten filament, vacuum chamber, alumina ceramic tube, sealing ring, extracting vacuum pipe, siderochrome wire column, it is characterized in that: described alumina ceramic tube is a tubular structure, the structure two ends are packaged with siderochrome aluminum conductor post respectively with sealing ring, making the inner formation of described alumina ceramic tube is a vacuum chamber, is packaged with tungsten filament in this vacuum chamber; Wherein be preset with the extracting vacuum pipe on the end sealing ring; Welded closure after the extracting vacuum.
After adopting such structure, the pyrotoxin tungsten filament is in vacuum state, thereby avoids oxidation, has improved useful life.Compare with existing Globar heating element, prolong 3-5 useful life doubly.
Description of drawings
It shown in the accompanying drawing schematic diagram of the utility model concrete structure.
Specific implementation method
