Product Overview
Continuous Casting Billet Secondary Reheating Equipment is applied for supplementary heating of billets directly off continuous casting lines, fixing insufficient pre-rolling temperature and uneven temperature difference across billets. The following sections detail the mechanical structure and control parameters of the equipment.
Power Supply Configuration
1.The unit is equipped with dual-rectifier 12-pulse or 24-pulse power supply, rated power ranging from 1000KW to 12000KW and operating frequency set between 500Hz and 1200Hz.
2.Two operation modes are available: standalone operation of single power unit and parallel combined operation of multiple units, with flexible configuration based on on-site production capacity.
Production Capacity and Applicable Billet Specifications
1.Production capacity: Hourly output ranges from 40 tons to 300 tons, matching production demands of medium, small and large-scale steel mills with continuous production lines.
2.Applicable billet parameters: Compatible with square billets of 100mm–200mm cross-section and 3000mm–12000mm single length, covering mainstream square billet dimensions in the steel industry, which are standard processing raw materials matched by Continuous Casting Billet Secondary Reheating Equipment.
Feeding and Transmission System
1.Each conveying roller is driven by an independent motor matched with a reducer, adopting multi-shaft synchronous layout for the whole equipment.
2.All drive shafts are regulated by a unified frequency converter to realize synchronized rotation speed, preventing billet jamming and deviation during transportation.
Guide and Limiting System
1.Guide wheels are made of 304 non-magnetic stainless steel to avoid magnetization and extra heat loss caused by alternating magnetic field.
2.Axial elastic allowance is reserved on guide wheels to accommodate permissible bending deformation of billets under national standards and stabilize billet moving track.
Closed-loop Temperature Automatic Control System
1.System composition: Infrared temperature detectors cooperate with PLC to form a full closed-loop temperature control circuit.
2.Control logic: The system collects real-time data of incoming billet temperature and feeding speed, then dynamically adjusts output power of the power supply automatically.
3.Control target: Stabilize billet outlet temperature at preset value and eliminate temperature fluctuation from inconsistent head-tail temperature and varying incoming blank temperature.
Industrial Intelligent Control System
Data visualization
Real-time display of equipment operating parameters and overall running status.
Billet data management
Process parameters are stored locally and printable for production traceability.
Safety protection
Acoustic and light alarm triggers upon equipment failure; power supply automatically reduces output under abnormal conditions to maintain constant billet temperature and cut reject rate.
Manufacturer Advantages (Hebei Yuantuo Electromechanical)
1.Complete machine independent production, with self-produced core power supply, transmission parts and control system; customized power, output and billet specifications are available.
2.The equipment fits secondary reheating process for as-cast billets, compensating temperature drop of continuous casting blanks and improving finished product rate in subsequent rolling process.
3.Modular overall design simplifies field installation, disassembly and later maintenance of spare parts.
