1. Series Overview

2. Operating Principle

1. Sealed Melting & Steady Pool Maintenance

   Precious metal raw materials are loaded into the fully enclosed induction crucible, where the system rapidly reaches target temperature under inert gas atmosphere. Once fully melted, the precision control system maintains a stable molten pool to ensure consistent fluidity and homogeneous alloy composition throughout long production runs.
2. Precision Crystallization & Directional Solidification

   Molten metal flows by gravity into a water-cooled precision crystallizer, where the outer layer solidifies rapidly while the core remains molten. Controlled cooling intensity enables directional grain growth, eliminating internal porosity and ensuring uniform material density.
3. Servo-Controlled Continuous Drawing

   A servo-driven traction mechanism pulls the forming profile downward at a fully adjustable, constant speed, synchronized with cooling output to match solidification rate. This closed-loop control achieves uninterrupted one-step forming with consistent dimensional accuracy.
4. Inline Discharge & Downstream Integration

   Continuously cast profiles are discharged steadily at a fixed height, compatible with standard downstream rolling mills, wire drawing machines and cutting equipment for inline production integration.
5. Quick Mold Change for Multi-Profile Production

   By swapping crystallizer molds of different geometries, the machine can switch between rods, strips, tubes, plates and custom cross-sections, adapting to diversified product portfolios without additional equipment investment.

3. Core Advantages

• Scalable Dual-Capacity Platform

  The two models share identical body dimensions, mounting footprint, control system and crystallizer specifications. Users can select capacity based on current output needs, and upgrade production scale later without workshop modification or re-training for operators, significantly lowering expansion costs.
• Steady-State Thermal Control for Batch Consistency

  ±1℃ high-accuracy temperature regulation maintains a stable molten pool during continuous operation, eliminating alloy segregation and ensuring consistent material properties, grain structure and surface quality across entire production batches.
• Full-Process Inert Gas Shielding

  The fully enclosed melting and forming chamber runs under positive inert gas protection from charging to discharge, completely isolating oxygen to produce bright, oxide-free surfaces. This removes the need for secondary pickling or face milling, reducing material loss and post-processing labor costs.
• Flexible Multi-Profile Production Capability

  Quick-change crystallizer design supports round bars, square bars, flat strips, seamless tubes and flat plates, enabling manufacturers to cover multiple product lines with a single unit and improve equipment utilization.
• Industrial Build for Multi-Shift Operation

  Constructed with heavy-duty industrial components and a modular structure, the series is engineered for long-hour, multi-shift continuous production, with high uptime and simplified routine maintenance to reduce long-term operating costs.
• Safety & Operational Simplicity

  The fully enclosed melting structure eliminates high-temperature metal splashing risks. The integrated control panel with real-time parameter display allows operators to master full production workflows with minimal training.
