Embodiment Construction

[0013] The invention belongs to a six-element aviation resistance furnace heater, in particular, the optimized arrangement of heating elements improves the furnace temperature uniformity of the aviation industrial resistance furnace. Such as figure 1 As shown, it is provided with a number of heating unit areas 3 on the refractory support brick in the hearth 2 of the furnace body 1, and each heating unit area 3 is provided with a space area 5 where a heating element unit 4 can be installed; the same space area The heating element unit 4 in the 5 is connected to the power supply after being connected in series.

[0014] Such as figure 2 As shown, the space area 5 is divided into 6 space positions for heating element units, and 6 space positions are placed for 6 heating element units 4 of the same form. The heating element units 4 can be electrothermal alloy wires. The electrothermal alloy wire is wound into an electrothermal alloy wire with a helical pitch T along the length ...

Abstract

The invention relates to a resistance furnace heating device, in particular to a hexahydric resistance furnace heater for aviation, which is characterized in that a plurality of heating unit areas are arranged on refractory material support bricks in a hearth of a furnace body, and a space area capable of enabling a heating element unit to be installed is arranged in each heating unit area. The space area is divided into six space positions for containing six heating element units which are electric heating alloy wires wound to be the electric heating alloy wires with the helical pitch of T along the length direction. The hexahydric resistance furnace heater adapting to the resistance furnace optimization design for the aviation is provided.

Description

technical field [0001] The invention relates to a resistance furnace heating device for aviation, in particular to a six-element resistance furnace heater for aviation. Background technique [0002] Industrial resistance furnaces usually use electrothermal alloy wires as heating elements, through which electric energy is converted into heat energy, and the workpiece to be processed is heated by heat energy. In order to ensure the quality of the heat treatment of the workpiece, the uniformity of the furnace temperature is a very important indicator. In order to meet the requirements of this indicator, various means can be adopted. Usually, the heating elements are evenly arranged in the furnace, and this method can only meet the general requirements for furnace temperature uniformity. With the development of aerospace technology, the requirements for the temperature uniformity of aviation industrial heat treatment furnaces are getting higher and higher. For example, the fur...
