Elevate your steel rolling production with a reheating furnace engineered for unmatched efficiency, fuel flexibility, and premium billet quality. Gongyi Hengyuan Industry Co., Ltd. – a leading expert in industrial furnace design and manufacturing – proudly presents our 6m Square Billet Conventional Pulse Combustion Natural Gas/Heavy Oil Dual-Fuel Walking Beam Reheating Furnace with cantilever roller side in/out operation.
As a turnkey EPC solution (Engineering, Procurement, Construction), this furnace delivers a rated cold billet output of 80t/h, perfectly matching an annual hot-rolled production capacity of 500,000 tons. It is precision-built to heat carbon steel, high-quality special steel, stainless steel, ferritic stainless steel, alloy steel and more – all while meeting the steel industry’s strictest demands for low consumption, high automation, and environmental compliance. For rolling mill upgrades or new project builds, this is the all-in-one heating solution that drives productivity and profit.
Unrivaled Fuel Flexibility & Industry-Leading Energy Efficiency
Say goodbye to single-fuel limitations with our seamless online dual-fuel switching system (natural gas/heavy oil) – no shutdowns required, adapting to your energy supply strategies and market fuel price fluctuations at any time. Boasting international standard low calorific values (9,000 Kcal/Nm³ for natural gas, 11,000 Kcal/Kg for heavy oil), the furnace achieves ultra-low specific fuel consumption: ≤30 Nm³ natural gas or ≤26 Kg heavy oil per ton of cold billet.
Our three-zone controlled pulse combustion system ensures flexible heat load adjustment and minimal furnace pressure fluctuation, while a 260m² high-power counter-flow air preheater preheats combustion air to over 350°C – maximizing flue gas waste heat recovery and boosting combustion efficiency to industry-leading levels. Paired with real-time residual oxygen detection for dynamic air-fuel ratio optimization, we eliminate fuel waste, reduce billet oxidation scaling, and prevent black smoke emissions – balancing significant energy savings and eco-friendliness in every production cycle.
Precision Heating for Superior Billet Quality & Rolling Precision
Every design detail is optimized to deliver uniform, consistent billet heating that elevates your final product quality and rolling precision. Featuring a top-bottom double-sided, three-zone heating process (8:92 soaking/heating load ratio, 25:75 top/bottom load ratio), the furnace ensures a billet exit temperature deviation of ≤30°C and a temperature difference of ≤30°C in all directions (excluding water beam contact points) – fully meeting the strict temperature requirements of advanced rolling processes.
Innovative variable-track water beam and high-low heat-resistant steel pad technology (100mm 2848-grade pads for high-temperature furnace zones, 70mm 2520-grade pads for other areas) drastically reduces water beam indentation marks on billets, significantly improving the rolling precision and mechanical properties of your finished steel products. Under natural gas combustion, the billet oxidation scaling rate is kept at ≤0.8% – minimizing raw material loss and boosting your overall material utilization rate for higher profitability.
Robust Mechanical Design for Reliable High-Load Operation
Built to withstand the rigors of continuous industrial production, our furnace features a hydraulically driven modular wheel set inclined rail walking mechanism with adjustable step distance (≈220mm), lifting stroke (200mm) and walking cycle (≈30s). Proportional valve control and high-precision stroke detection enable “soft lift and soft drop” of billets, reducing oxide scale shedding and impact damage to water beam insulation – ensuring long-term structural integrity and minimal maintenance.
The furnace is equipped with 3 fixed + 2 movable water beams (20G boiler tube construction) and a forced circulation evaporative cooling system with real-time pressure/flow monitoring at all water return points, guaranteeing stable and safe operation even at a maximum heating temperature of 1150°C. An integrated water seal slag removal system automates oxide scale collection and removal – no manual intervention required, cutting maintenance workload and keeping your production line running smoothly and continuously.
Intelligent Automation & Intuitive, Low-Labor Operation
Minimize manual labor and maximize operational control with our Siemens S7-1500 dual PLC intelligent control system, which integrates electrical, instrumentation and control technologies to support automatic/semi-automatic/manual operation modes – all tailored to your specific production scenarios and operational needs. A 27-inch LCD operator station with a user-friendly HMI displays real-time key parameters (furnace temperature, pressure, medium flow, equipment status) and stores up to 1 month of historical trend data for easy production analysis and optimization.
The furnace temperature automatic control system boasts an input rate of ≥99%, while 2 sets of high-temperature industrial TV systems (installed at the feeding and discharging ends) and an 8-point normal temperature online monitoring system enable full remote oversight of billet movement and equipment performance from the central control room. This not only slashes on-site labor intensity but also eliminates operational safety risks – putting full, precise control of your heating process at your fingertips.
Comprehensive Safety & Strict Environmental Compliance
We prioritize production safety and environmental sustainability in every design choice, with a mandatory safety interlock logic for the combustion system: quick-closing valves on natural gas and heavy oil main pipelines automatically cut fuel supply and trigger furnace shutdown in case of abnormal conditions (low fuel/air/cooling water pressure, fan failure). Eight high-sensitivity natural gas leak detectors provide instant alerts in the furnace area, and dedicated nitrogen purging/venting devices prevent explosive gas mixtures during furnace startup and shutdown.
The furnace body adopts an optimized integral cast composite insulation lining (ultra-low carbon cement castable + lightweight insulating brick + aluminum silicate fiberboard), ensuring surface temperatures fully comply with GB/T 16618-1996 industrial furnace insulation standards and minimizing heat loss for further energy savings. Fans are sound-isolated with shock absorbers and silencers (noise levels compliant with GBJ87), and all operating platforms, ladders and guardrails meet international safety standards – creating a safe, low-noise, eco-friendly production environment for your team.
