Embodiment Construction

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

[0014] Such as figure 2 As shown, the heating element unit with a pitch of T+2T is mixed, and the electrothermal alloy wire is wound into a heating element unit with different pitches. In the length direction of the heating element unit, the helix is ​​wound within 1 / 4 of the length of both ends. The pitch is T, and the pitch of the spiral wound in the middle 1 / 2 leng...

Abstract

The invention relates to an arrangement method of heating elements of a resistance furnace for aviation, which is characterized in that: a heating unit area is arranged on the refractory material support brick in the hearth of the furnace body, and a space area capable of installing the heating element unit is arranged in the heating unit area ; The space area is divided into a space where 6 heating element units can be placed, and the heating element units in the space area are connected to the power supply after being connected in series; the heating unit area is divided into 6 spaces, and 1 / 4 of the two ends of the 6 heating element units The pitch of the spiral wound within the length is T, and the pitch of the spiral wound within the middle 1 / 2 length is 2T. It provides an arrangement of heating elements of an aviation electric resistance furnace to overcome the defects in the prior art.

Description

technical field [0001] The invention relates to an arrangement method of heating elements of an aviation resistance furnace. 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 furnace temperature uniformity of heat treatmen...
