In figure：1st, air inlet, 2, shell, 3, temperature detector, 4, exhaust outlet, 5, heater, 6, bottom, 7, cock body.
Specific embodiment
In order to be better understood from the present invention, the present invention is further retouched with reference to specific embodiments and the drawings
State.
As Figure 1-4, a kind of Production for Steel Wire protection gas firing equipment, including shell 2, the shell 2 includes refractory layer
With the heat-insulation layer being coated on the outside of the refractory layer.Refractory layer can also be able to be organic polytetrafluoroethyl-ne for inorganic carbide silicon materials
Alkene material, and heat-insulation layer is then with polystyrene foamed material or polyurethane foamed material.
The front end of the shell 2 is provided with air inlet 1, and the rear end of the shell 2 top is provided with exhaust outlet 4, inside the shell 2
Heater 5 is installed.The heater 5 includes multiple heating dish, and air vent is offered in each described heating dish, adjacent
Air vent perforate direction in the heating dish is in a certain angle, multiple heating dish by connecting tube be fixed as one it is whole
Body, is provided with electrical heating wire in the connecting tube.
By the way that traditional pipe type heating device to be replaced by the heater 5 of multiple heating disc types in the design, and pass through
Connecting tube is fixed as an entirety so that the structure of the heater 5 is more simple, easier for installation.
By opening up air vent in the heating dish, and adjacent air vent perforate direction is set to there is certain angle,
The present embodiment is 90 ° of angles.The air vent angle of certain multiple heating dish can successively differ an acute angle, such as 30 °, 45 °,
60°.This causes that stream of nitrogen gas is internally formed turbulent flow in the shell 2, and then lifts the uniformity of stream of nitrogen gas temperature.
