Annealing furnace

Abstract

The invention discloses an annealing furnace, which includes a furnace body (3), a heating mechanism and a feeding mechanism. The feeding mechanism consists of a support (2) and several carrying rollers (1). The carrying rollers (1) are disposed on the support (2) to compose a track (4) for conveying workpieces. The annealing furnace also includes a water circulation mechanism, and the water circulation mechanism consists of a water inlet pipe (5), a recovery water pipe (6) and a circulation steam pocket (7). The circulation steam pocket (7) is equipped with a water inlet hole (8), one end of the water inlet pipe (5) and one end of the recovery water pipe (6) are both connected to the circulation steam pocket (7), the carrying rollers (1) in the furnace body (3) are internally provided with cooling channels, the inlets of the cooling channels are connected to the other end of the water inlet pipe (5), and the outlets of the cooling channels are connected to the other end of the recovery water pipe (6). The annealing furnace provided by the invention makes the carrying rollers have long service life and greatly reduces the cost.

Description

technical field [0001] The invention relates to heat treatment equipment, in particular to an annealing furnace. Background technique [0002] Annealing is a common process in material 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 property. The annealing furnace is an indispensable processing equipment in the annealing process. The idler is one of the important parts of the annealing furnace. The quality of the idler directly determines the quality of the annealing of the workpiece. The idler keeps high temperature in the annealing zone. It is easy to be deformed and damaged in high temperature environment, and the service life is short. According to the existing technology, a cooling device for the idler in the annealing furnace is disclosed on the website of the State Intellectual Property Offic...

The annealing furnace is an indispensable processing equipment in the annealing process. The idler is one of the important parts of the annealing furnace. The quality of the idler directly determines the quality of the annealing of the workpiece. The idler keeps high temperature in the annealing zone. It is easy to be deformed and damaged in high temperature environment, and the service life is short. According to the existing technology, a cooling device for the idler in the annealing furnace is disclosed on the website of the State Intellectual Property Office. The patent number is 201320465673.5. There is an annular inner cavity in between, and the water enters and exits from the same side of the roller sleeve to complete the cooling of the roller, and the cooled water is directly discharged, causing waste and greatly increasing the cost
