Description

Technical Field

[0001] This utility model relates to the field of annealing furnace technology, and in particular to a multi-zone temperature-controlled bearing steel annealing furnace. Background Technology

[0002] GCr15 steel is a major type of bearing steel, generally delivered in hot-rolled condition. Before bearing manufacturing, it requires spheroidizing annealing. Spheroidizing annealing reduces the hardness of the bearing steel, making it easier to machine. Through spheroidizing annealing, a ferrite matrix with uniformly distributed fine spherical carbide particles is obtained, preparing for the final quenching and low-temperature tempering treatment to obtain a cryptocrystalline martensite structure with fine carbides. The annealing furnace is equipped with multiple heating devices, allowing for different temperatures within the furnace, enabling multi-zone heating annealing. The heating components are electrically connected to temperature sensors, allowing for temperature control of different zones.

[0003] Existing annealing furnaces require immediate heat dissipation after heating, and reheating is necessary when heating the next batch of bearing steel, resulting in significant heat loss and waste. Therefore, we propose a multi-zone temperature-controlled bearing steel annealing furnace. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] (1) A multi-zone temperature-controlled bearing steel annealing furnace of the present invention places bearing steel inside the bearing steel placement tank and controls the bearing steel placement tank to move to the top of the heating furnace body. The electric slider is controlled to move above the electric slide rail, so that the bearing steel placement tank can slide into the interior of the heating furnace body. During the sliding process, the first transmission gear above the rotating shaft meshes with the rack, so that the first transmission gear can drive the rotating shaft and the sealing cover plate to rotate.

[0015] (2) The present invention provides a multi-zone temperature-controlled bearing steel annealing furnace. After the turntable rotates, it can drive the bearing steel placement tank and the bearing steel inside it to rotate. Through centrifugal force, the bearing steel collides with the bearing steel placement tank, thereby breaking the carbonized particles on the top of the bearing steel, which facilitates uniform heating of the high-temperature bearing steel. After the heating is completed, the bearing steel placement tank can be controlled to rise, and the first motor inside the rotating seat can be started. The first motor can drive the drive shaft and the mounting frame to rotate. The mounting frame can move the heated bearing steel placement tank to the interior of the cooling furnace for cooling.
