Embodiment Construction

[0054] The invention belongs to the arrangement of heating elements of an industrial resistance furnace, in particular, the optimized arrangement of the heating elements improves the furnace temperature uniformity of the industrial resistance furnace for aviation.

[0055] According to the size of the furnace hearth, you can choose Figure 4 to Figure 38 Several types of furnaces are combined (see Table 1 to Table 3) to form the heating zone of the furnace to meet the requirement of furnace temperature uniformity ≤ 5 °C.

[0056] In the present invention, the units of three kinds of heating elements are combined into various heating zones to meet the requirement that the furnace temperature uniformity is ≤5°C. Example A heating zone is composed of the following units, and the maximum number of units in the heating zone is 6.

[0057] The combination method of the aviation heater in the embodiment of the present invention is characterized in that several heating unit areas are...

Abstract

The invention relates to a combination method for an aviation heater, which is characterized in that a plurality of heating unit areas (3) are arranged on refractory supporting bricks in a hearth of a furnace, a spatial area (5) capable of holding heating element units (4) is arranged in each heating unit area (3) and divided into spatial positions capable of holding more than three heating element units (4), the heater can be formed by combining a plurality of heating unit areas (3) of the same structure or of different structures, and the heating element units (4) placed in the same heating unit area (3) are connected to a power supply after series connection. According to different spatial environments, different hearth sizes and different requirements on heat, combination forms can meet different requirements. As each spatial area (5) is divided into the spatial positions capable of holding six heating element units in various distribution modes, the combination method is even in heating and precise in temperature control.

Description

technical field [0001] The invention relates to a combination mode of an aviation heater. 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 treatment trolley furnaces is required to b...
