Description

Technical Field

[0001] This utility model relates to the field of heat treatment furnace technology, specifically a nanocrystalline magnetic core heat treatment furnace. Background Technology

[0002] A heat treatment furnace refers to an electric or fuel-fired furnace used for heating furnace charge for heat treatment. Commonly used heat treatment furnaces include box-type resistance furnaces, pit-type resistance furnaces, gas carburizing furnaces, and salt bath furnaces. Continuous furnaces are typically used, with workpieces continuously loaded through the charging door, passing through the furnace chamber, and continuously discharged through the discharge door. A common method for in-furnace conveying is to place the workpieces on heat-resistant steel guide rails and move them using walking beams or pushers. In recent years, heat-resistant steel conveyor belts have been increasingly adopted. This makes heat treatment operations more rational and greatly increases the possibility of automation and unmanned management of the heat treatment process.

[0003] A utility model patent with patent authorization announcement number CN114883074A discloses a heat treatment furnace for nanocrystalline magnetic cores. The furnace includes a frame and a heat treatment device mounted on the frame. The heat treatment device has an inlet and an outlet, and a conveying assembly carrying nanocrystalline magnetic cores circulates between the inlet and outlet. The heat treatment device has a heat treatment channel with an inner diameter matching that of the conveying assembly, and the conveying assembly travels within the heat treatment channel. Multiple independently temperature-controlled heating zones are arranged within the heat treatment channel, and a magnetizing assembly is provided on the heat treatment device. The magnetic field formed by the magnetizing assembly surrounds the heating zones through which the nanocrystalline magnetic cores crystallize. This invention offers high heating efficiency, enables continuous heat treatment, and eliminates the need for inert gas or vacuum environments.

[0004] Currently, some heat treatment furnace doors are connected by hinges, which makes the door limit unstable, causing many inconveniences for loading and unloading. In addition, nanocrystalline magnetic core materials are mostly placed in a container, and the nanocrystalline magnetic core materials are piled up together. The material piled up inside the nanocrystalline magnetic core materials is not easy to heat treat, which causes many inconveniences for the heat treatment of nanocrystalline magnetic core materials.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a telescopic rod connected to the upper end of a crossbar. The telescopic rod suspends the end cover, which allows the end cover to be raised and lowered easily. This enables the end cover to automatically engage with the upper end of the heat treatment furnace. Furthermore, the telescopic rod drives the end cover to rise, causing the end cover to automatically separate from the heat treatment furnace, thus achieving the effect of automatically limiting the end cover and preventing unstable end cover positioning from affecting loading and unloading operations.
