1. Project Background & Operational Requirements This project involved a customized industrial Tellurium melting system for a refinery in Thailand (PMR-TH). With a melting point of 449.5°C, Tellurium is highly volatile and corrosive to crucibles and thermocouple protection tubes at elevated temperatures. The client’s primary requirements were stringent temperature consistency and operational safety during high-capacity discharging. In response, we deployed the WDL-DGQ-600 Hydraulic Tilting Resistance Furnace. 2. Technical Solution: Stability Backed by Parameterized Evidence To ensure long-term reliability under continuous thermal cycles, the solution was engineered with specific technical parameters: High-Efficiency Thermal Engineering (Lining Design): The furnace shell features a fully sealed, welded steel structure. Instead of conventional bricks, the lining utilizes compressed ceramic fiber modules secured by stainless steel anchors. Under a 50Kw rated power load, this configuration accelerates heating cycles and minimizes heat loss through the shell, ensuring consistent energy efficiency. Redundant Dual-Loop Temperature Control (Monitoring): The system integrates two sensors. One monitors the furnace chamber to prevent overheating of the heating elements (16.6Kw/pc); the other uses a silicon nitride protection sleeve to measure the 600KG molten pool directly. This setup maintains temperature fluctuations within ±1°C at a standard operating temperature of 600°C. Precision Hydraulic Tilting (Safety Architecture): To manage the 600KG liquid mass, an independent hydraulic station was integrated. Compared to mechanical tilting, the hydraulic drive ensures smooth angular velocity, effectively preventing molten metal splashing during the pouring process. 3. Consumable Selection & Maintenance Reliability Given the chemical reactivity of Tellurium, high-specification materials were utilized in critical areas: Crucible Safety: A Z-803 graphite crucible was selected, complemented by a leak detection device at the furnace base. This provides an early warning of crucible structural failure, protecting the heating elements from potential leakage. Power Regulation: The electrical system utilizes TSCR-4-4-100P thyristors and fuse protection. This ensures smooth current output during high-load switching, significantly extending the service life of the spiral resistance wires. 4. Deliverables & Performance The system includes the furnace body, hydraulic platform, and a dedicated dust collector. All technical documentation, including bilingual electrical schematics, supported rapid on-site commissioning in Thailand. Performance tests confirmed that the equipment maintains superior thermal stability within its operational range, fully meeting the client’s production standards.

1. Thermal Uniformity: Ensuring Hardness Consistency for Batch Parts In the mass production of precision molds, carbon steel, and powder metallurgy products, the consistency of the nitriding layer is a key benchmark of process quality. The RN-60-6 Pit Type Nitriding Furnace, within its Ø700×900mm effective work zone, utilizes a full-fiber lining structure, significantly reducing heat storage loss compared to traditional brick linings. Equipped with a circulating fan driven by a 1.5kW water-cooled anti-corrosion motor, the system achieves high-efficiency forced convection of gas, maintaining ±5℃ temperature uniformity to ensure uniform nitriding depth across all parts in a single batch. 2. Core Thermal Power and Control Logic: ±1℃ Precision Operation Temperature fluctuations during nitriding directly impact nitrogen potential stability. The equipment features a 60kW rated power system (1-100% adjustable), utilizing 0Cr25AL5 high-performance resistance strips as the heat source. The side-wall heating layout ensures balanced radiation. The core control unit incorporates Shimaden (Japan) intelligent instruments with automated nitrogen potential control, achieving a temperature control accuracy of ±1℃. This high-sensitivity closed-loop regulation not only shortens heating time but provides superior thermal stability throughout long nitriding cycles, effectively preventing brittle phases on the workpiece surface. 3. Digital Monitoring and Intrinsic Safety: Adaptability to Modern Workshops Designed for continuous indoor operation, the equipment strictly controls heat dissipation, maintaining a furnace shell surface temperature of ≤40℃+ambient, greatly improving the operator's environment. The system integrates over-temperature alarms and a 2-way (middle and lower) intake pipe design for flexible atmospheric adjustment. All critical operational data is displayed via digital instruments, paired with an electric screw rod lifting mechanism, ensuring that the RN-60-6 provides high operational safety and process traceability when handling high-value mold steels, supporting enterprises in achieving rigorous quality certifications.

1. Large-Scale Processing: 15m Zinc Kettle Process for Over-length Components In the anti-corrosion treatment of large road/bridge components and power towers, workpiece length is often a rigid bottleneck. This linear hot-dip galvanizing line features a massive zinc kettle with internal dimensions of 15m × 1.8m × 3.2m. With a molten zinc capacity of 510 tons, the system easily accommodates over-length steel structures within a 15-meter span, ensuring uniform heating and coating thickness during immersion and effectively eliminating oxidation risks associated with "segmental double-dipping." 2. Power Configuration & Energy Management: High-Efficiency Rhythm Supported by 480kW Total Load To drive this extensive industrial system, the line is configured with a total power consumption of approximately 480kW. In terms of process logic, energy is precisely distributed across critical nodes: the 185kW side-suction zinc fume exhaust fan and the 55kW acid mist purification system form the core of the energy cycle. This high-power configuration ensures that while the liquefied gas heating system maintains constant temperature curves, auxiliary systems like the 22kW furnace blower and 15kW iron removal equipment collaborate efficiently, significantly increasing the turnover rate per ton of components. 3. Intrinsic Environmental Protection: Side-Suction Tech & Closed-Loop Fume Control As environmental regulations tighten globally, the treatment of dust and acid mist has become a market entry barrier. This production line deeply integrates environmental modules, utilizing a 185kW powerful side-suction zinc fume treatment system combined with automated filtration devices to achieve an intrinsically clean workshop. All emission data is linked to the core control system, which, through the flexible regulation of the 480kW power assembly, ensures that exhaust meets environmental standards without compromising production rhythm—providing a strong compliance backing for international engineering bids.
