Roller Hearth Spheroidizing Annealing Furnace

The roller hearth spheroidizing annealing furnace is a high-end heat treatment equipment specially developed by Wongsteel (Beijing Yijing Technology) for metal wire rods, bars and other products. It is mainly used for spheroidizing annealing, softening annealing and stress relief annealing of various steels such as medium & low alloy steels, bearing steels and tool steels. It is widely used in industries such as steel wire, fasteners, bearings and mechanical processing, serving as core equipment to improve the cold working performance and optimize the internal structure of steel.

The equipment adopts a roller hearth continuous heat treatment structure, with a furnace capacity of 24-32 tons. It can adapt to the heat treatment needs of a full range of cold heading steels, alloy structural steels and bearing steels such as SWCH6A-22A, 10B21/10B33/SWCH25K-45K, SCM435/40Cr. It provides precise process parameter matching for different steel grades and wire specifications (≤10mm, ＞10mm), with spheroidizing annealing processing time covering 19-28 hours, ensuring uniform internal structure and qualified spheroidization rate of steel, fundamentally improving the cold heading performance, drawing performance and subsequent processing stability of wire rods.

The core advantages of the equipment are precise temperature control, stable operation and controllable energy consumption. It adopts an advanced heating and insulation system to achieve uniform distribution of temperature field in the furnace, ensuring consistent heat treatment effect of the whole furnace steel. The roller hearth conveying structure can realize continuous and automated production, greatly improving heat treatment efficiency and reducing labor costs. At the same time, it is equipped with complete safety protection and intelligent control system, which is easy to operate and complies with industrial production safety standards. Compared with traditional box-type annealing furnaces, the roller hearth spheroidizing annealing furnace achieves significant upgrades in processing efficiency, product consistency and energy consumption control, which can effectively improve the heat treatment capacity and product quality of enterprises.

The equipment can provide customized furnace size and process solutions according to customers' steel types, wire specifications and capacity requirements, as well as professional installation and commissioning, technical training and after-sales maintenance services, helping metal product enterprises optimize heat treatment processes, reduce production costs and improve product market competitiveness.
