Annealing furnace

Abstract

The invention provides an annealing furnace which comprises a furnace shell, a hearth, a furnace door, heating elements, a temperature thermocouple and an intelligent temperature controller. The annealing furnace is characterized in that the furnace door is of a side opening type structure and is arranged on a panel of the furnace shell through multiple sets of hinges, the hearth is closed and is provided with a furnace opening, a protruding block matched with the furnace opening is arranged on the furnace door, and the protruding block tightly presses and is tightly attached to the interior of the furnace opening; a handle is arranged on the furnace door, the position between the furnace shell and the hearth is filled with a thermal insulation layer, and the heating elements surround the four walls of the hearth; a containing support and a rail are arranged inside the annealing furnace, and therefore materials can be continuously pushed into and ejected out of the annealing furnace, the automatic degree is high, and the labor amount is reduced; and the temperature in the hearth is even, the machining efficiency is greatly improved, and the energy resource using rate can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of heat treatment equipment, in particular to an annealing furnace. Background technique [0002] Annealing is a common process in the machining process. In order to achieve certain characteristics, such as reducing the hardness of the workpiece and improving its plasticity, the workpiece needs to be heated, kept for a period of time, and then slowly cooled to obtain this kind of performance. The annealing furnace is an annealing furnace. Indispensable processing equipment in processing, the insulation effect of the traditional annealing furnace insulation layer is not good, which affects the annealing effect, and the existing annealing furnace is not highly automated, usually the furnace in the annealing furnace is removed from the annealing furnace first. Take out the furnace, put the workpiece into the furnace, and then put the furnace into the furnace and heat it to the preset temperature and keep it for...

[0002] Annealing is a common process in mechanical processing. In order to achieve certain characteristics, such as reducing the hardness of the workpiece and improving its plasticity, the workpiece needs to be heated for a period of time, and then slowly cooled to obtain this performance. The annealing furnace is an annealing furnace. Indispensable processing equipment in processing, the thermal insulation effect of the traditional annealing furnace insulation layer is not good, which affects the annealing effect, and the existing annealing furnace is not highly automated. Usually, the furnace in the annealing furnace is first removed from the annealing furnace Take out the furnace, put the workpiece into the furnace, and then put the furnace into the furnace to heat to the preset temperature and keep it for a certain period of time, then withdraw the furnace from the furnace of the annealing furnace, and then take the workpiece out of the furnace. This kind of annealing furnace cannot be fed continuously and is inconvenient, and the degree of automation is not high, which greatly affects the processing efficiency of the workpiece
