Charging/Discharging System for Reheating Furnaces

Product Specifications

Technical details and manufacturing context for Charging/Discharging System

Definition

The Charging/Discharging System is a specialized mechanical component integrated into reheating furnaces used in basic metal manufacturing. It handles the controlled insertion (charging) of cold or pre-heated materials into the furnace and the extraction (discharging) of heated materials from the furnace. The system ensures proper material flow, positioning, and timing to maintain furnace efficiency and product quality. It typically employs conveyors, pushers, extractors, or walking beams to move materials. During charging, it positions the material at the furnace entrance; the furnace's internal mechanism then moves it through heating zones. Upon completion of the heating cycle, the discharging mechanism retrieves the hot material from the furnace exit and transfers it to the next processing stage, such as rolling or forging. The system is designed for heavy-duty operation, with a rated load capacity of 5–20 tonnes per charge and an operating speed of 0.1–0.5 m/s. Positioning accuracy is ±5 mm to ensure correct placement. It operates in ambient temperatures from -20°C to 60°C and can handle materials up to 1200°C. Drive power ranges from 5.5 to 22 kW, with supply voltage of 380–480 V AC (three-phase, 50/60 Hz, per IEC 60038) and control voltage of 24 V DC. Ingress protection is IP54–IP65 per IEC 60529. Structural or stainless steel grades Q235B/304 are used, referencing GB/T 700 and GB/T 3280. Overall dimensions are customizable (3000–8000×1500–3000×1000–2000 mm), and total weight ranges from 3000 to 15000 kg. Materials on file include heat-resistant alloy steel, refractory materials, and ceramic components. These specifications are reference ranges; verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The system uses a combination of conveyors, pushers, extractors, or walking beams to move materials. During charging, it positions the material at the furnace entrance. The furnace's internal mechanism then moves it through heating zones. Upon completion of the heating cycle, the discharging mechanism retrieves the hot material from the furnace exit and transfers it to the next processing stage, such as rolling or forging.

Frequently Asked Questions

What is the typical load capacity of this charging/discharging system?

The rated load capacity is 5–20 tonnes per charge, as listed in the reference parameters. However, the exact capacity depends on the specific model and furnace layout, so you should confirm with the manufacturer or supplier.

What materials are used in the construction of the system?

The system may use heat-resistant alloy steel, refractory materials, and ceramic components. Structural or stainless steel grades Q235B or 304 are referenced, but the actual material grade should be verified with the supplier for your application.

What is the positioning accuracy of the system?

The positioning accuracy is ±5 mm, which ensures correct placement of materials in the furnace. This value is a reference and may vary with the specific model and installation.

What standards apply to the electrical and protection aspects?

The supply voltage references IEC 60038, and ingress protection references IEC 60529 (IP54–IP65). These are procurement references; compliance should be confirmed with the manufacturer.
