Abstract

The invention relates to an aviation resistance furnace heating element layout method which is characterized in that: a heating unit area is arranged on a support brick which is made of a refractory material in the hearth of a furnace body, and a space area in which heating element units can be arranged is arranged in the heating unit area; the space area is divided into spaces which can contain six heating element units, and the heating element units in the space area are connected to a power supply after being serially connected; and the heating unit area is divided into six spaces, and at least three heating element units can be arranged in the six spaces as required and are fixed in the space area. The invention provides the aviation resistance furnace heating element layout method, so that the defects in the prior art are overcome.

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...
