Newly Upgraded
steel bar induction hardening and tempering equipment Achieves Uniform Internal and External Through Heating with Zero Temperature Difference In response to the long-standing industry pain points of traditional steel bar heat treatment equipment, such as inconsistent internal and external temperature, uneven heating, unstable material mechanical properties and high product defect rates, the newly upgraded Steel Bar Heat Treatment Furnace has officially launched a comprehensive technological iteration. Focusing on the core breakthrough of
internal and external through heating with no temperature difference, the equipment optimizes the heating structure, energy supply system and intelligent temperature control technology, completely solving the heating quality bottleneck of round steel, deformed steel bar and alloy steel bar heat treatment, and bringing a new standard for high-precision metal heat treatment production.
The biggest upgrade highlight of the new-generation steel bar induction heat treatment machine is the innovative through-heating heating system. Traditional equipment mostly adopts single-sided radiation heating, which leads to high surface temperature and low internal temperature of steel bars, resulting in residual stress, uneven hardness and easy bending and deformation of finished products. The upgraded equipment adopts a full-circumference three-dimensional uniform heating structure, matching with high-frequency electromagnetic induction heating technology, which realizes synchronous heating from the core to the surface of the steel bar. It effectively eliminates radial temperature difference, achieving truly uniform internal and external through heating, and the overall temperature deviation is controlled within ±1℃.
In terms of production performance, the upgraded furnace has achieved dual improvements in efficiency and stability. The optimized heating cavity structure shortens the heating penetration cycle by more than 20% compared with traditional equipment, supporting continuous and uninterrupted feeding and heating of long and short steel bars. While ensuring zero temperature difference heating, the equipment reduces invalid heat loss, with the energy utilization rate increased by 35%, effectively lowering the comprehensive production cost of enterprises.
Equipped with a new intelligent constant-temperature control system, the furnace supports one-click parameter setting for different steel bar specifications and materials. It realizes real-time monitoring and automatic fine-tuning of heating temperature, operating power and processing speed, avoiding quality fluctuations caused by manual operation errors. In addition, the equipment retains the advantages of environmental protection and low consumption, with no open flame, no smoke and no harmful emissions during operation, fully complying with industrial green production standards.
Industry insiders said that the zero-temperature-difference through-heating upgrade of the
steel bar induction heat treatment production line has filled the technical gap of medium and high-precision steel bar heat treatment. It greatly improves the qualification rate and mechanical stability of heat-treated workpieces, and will become the core equipment upgrade choice for steel processing, hardware machinery and construction steel manufacturing enterprises.
