#1 Rebar Hardening & Tempering Machine ｜Steel Bar Heat Treatment Equipment

Precision Induction Quenching & Tempering Solves Pain Points of Traditional Heat Treatment

In infrastructure, mine support and prestressed component sectors, the performance stability of high-strength deformed rebar directly affects engineering safety. Traditional furnace heat treatment is plagued by slow heating, heavy oxide scale on rebar surface, uneven hardness, large straight-bar deformation and high energy consumption, restricting the qualification rate of finished products. The newly upgraded No.1 rebar hardening and tempering machine adopts continuous induction heat treatment to realize integrated online quenching and tempering of deformed rebar. Equipped with IGBT medium frequency induction power supply, the equipment features concentrated heat source and fast temperature rise. Heat is focused on the rebar matrix to cut invalid heat loss. It generates thin oxide layers and keeps the rebar rib profile intact without deformation, balancing strength, toughness and straightness to meet standards for high-strength seismic rebar.

Closed-Loop Automatic Control for Flexible Adjustment of Process Parameters

The complete rebar heat treatment unit adopts a closed-loop control system with PLC and infrared temperature measurement. Heating power, quenching water pressure, tempering temperature and conveying speed are adjusted in linkage. Preset process recipes can be quickly called up for deformed rebar of different specifications and materials. Axial and radial temperature differences are monitored in real time to keep hardness fluctuation within a narrow range. The roller conveyor structure supports continuous feeding of long rebar. Automatic loading, induction heating, spray quenching, holding tempering and discharging are completed in one sequence, cutting manual intervention and quality deviation caused by human operation. It supports quick specification changeover and works for ordinary deformed steel and alloy high-strength rebar with outstanding flexible production capacity.

Improved Quality and Reduced Consumption to Help Cost Reduction and Efficiency Gains

Compared with traditional bogie furnaces and pit furnaces, the induction rebar tempering machine greatly raises thermal efficiency and lowers energy consumption per unit product, complying with the low-carbon transformation trend of metallurgical heat treatment. Rebar after quenching and tempering obtains uniform metallographic structure with well-matched tensile strength, yield strength and elongation and excellent seismic performance. It reduces alloy addition for high-strength rebar and saves raw material costs for customers. Continuous production stabilizes single-shift output and reduces defect rates. It has wide application prospects in tunnel anchor bolts, bridge components, high-rise buildings and mine support.
