Description

Technical Field

[0001] The utility model relates to the technical field of steel processing, in particular to an annealing furnace for steel processing. Background Art

[0002] Annealing is a metal heat treatment process in which the metal is heated to a certain temperature, kept at a sufficient temperature for a sufficient period of time, and then cooled at an appropriate rate (usually slow natural cooling, sometimes controlled cooling). The purpose is to soften the material or workpiece that has been forged, cast, welded or cut, and to improve plasticity and toughness. This makes the chemical composition distribution more uniform, removes residual stress, or obtains the expected physical properties. There are many types of annealing processes depending on the purpose. In the process of processing steel, it is often necessary to process the steel through an annealing furnace.

[0003] The "trolley annealing furnace" disclosed in its application number "202320949879.9" "comprises an annealing furnace body, the inner wall of the annealing furnace body is slidably connected to a trolley, the top of the trolley is fixedly connected to a refractory layer, the top of the refractory layer is provided with a slot, the inner wall of the slot is clamped with a fixing seat, and the top of the fixing seat is fixedly connected to a frosted layer.
