1. Programmed Heating: Ensuring Refractory Longevity For 50-ton ladles, the consistency of lining baking determines the turnover cycle. The WDL-HB-50T system integrates a Siemens PLC automation core, allowing engineers to preset complex baking curves based on refractory material properties. Through a 10-inch color touch screen, the system provides real-time feedback on air-gas ratios and temperature fluctuations, automatically compensating gas flow to prevent lining spalling caused by rapid heating—transitioning from "manual ignition" to "digital programmed control." 2. Mechanical Stability Under Extreme Thermal Loads Under hours of intense heat radiation, mechanical reliability is paramount. The baker's body features a reinforced welded steel structure, with the lid lifting driven by a high-load hoist, ensuring smooth operation for the 50-ton class cover. Crucially, the burner nozzle is fabricated from 1Gr28Ni48W5 high-temperature pure metal. This anti-oxidation alloy resists thermal erosion and deformation, ensuring the flame remains centered throughout the cycle for a uniform radiation heat field. 3. Intrinsic Safety and Remote Process Collaboration Gas safety is embedded into every process node. The system is equipped with a dedicated Ultraviolet (UV) flame detector, capable of sensing unexpected flameouts and triggering an immediate full-system shutdown. Before ignition and after shutdown, the Nitrogen Purging system automatically clears residual gas from the lines, eliminating explosion risks. Furthermore, via the reserved Profinet communication interface, all onsite pressure and temperature data are seamlessly integrated into the factory’s central control system for real-time remote monitoring and collaboration.

A mid-western US automotive components manufacturer was facing growing pressure from OEM customers: tighter hardness tolerances, higher volumes, and stricter audit requirements. Their legacy box-type heat treatment furnace could no longer keep up — batch quality was inconsistent, energy costs were high, and the line could not match the takt time of the automated production cells. To solve this, the customer commissioned a special custom Tube Type Heat Treatment Furnace (Custom Heat Treatment Furnace, 580kW, 1100°C) designed and built by our team, dedicated to gears, shafts and other critical steel parts. Customer background & pain points The plant mainly processes automotive gears, shafts and differential components. Before the upgrade, they relied on an aging box-type Heat Treatment Furnace for carburizing, normalizing and tempering. Over time, several pain points became critical: Inconsistent hardness and microstructure Temperature uniformity was difficult to control, leading to noticeable batch-to-batch variation. Some parts required rework, directly impacting delivery and cost. High energy consumption per part Inefficient insulation and non-optimized burner/heating layouts meant the furnace consumed a lot of power to maintain temperature, pushing unit energy cost up. Bottleneck in an otherwise automated line The rest of the production line was largely automated (robot loading, conveyor transfer, automatic washing), but the old furnace still required manual loading/unloading and frequent operator intervention. Limited process window for future materials The existing system struggled near the upper end of its temperature range and offered little margin for new alloys or higher-temperature trials demanded by R&D. These issues made management look for a Tube Type Heat Treatment Furnace solution that could stabilize quality while lowering long-term operating costs. Key requirements for the custom heat treatment furnace During joint evaluation and design, the US customer defined several non-negotiable requirements: Installed power: 580kW to support high throughput while maintaining stable temperature during continuous loading. Maximum operating temperature: 1100°C, to cover current carburizing/normalizing cycles and future high-alloy trials. Full integration with existing automation – the furnace must accept parts from robots and conveyors, with repeatable positioning and smooth handover. Energy efficiency and safety compliance aligned with local US electrical and safety codes, supporting future third-party certification. Traceability – the Heat Treatment Furnace had to interface with the plant’s MES, logging temperature curves, holding times and recipes for every batch. The 580kW custom tube type heat treatment furnace solution Based on these requirements, we delivered a special custom Tube Type Heat Treatment Furnace configured as follows: Multi-zone tube design & temperature control A multi-zone tubular chamber with independently controlled heating zones to fine-tune the temperature profile along the furnace length. Maximum operating temperature of 1100°C, giving process headroom for carburizing, normalizing and high-temperature tempering. High-precision thermocouples combined with PID control to maintain strict temperature uniformity and reduce hardness scatter across parts. Energy optimization & safety features Upgraded insulation and optimized heating element layout to minimize heat loss, improving effective utilization of the 580kW installed power. Reserved interfaces for protective atmosphere and exhaust treatment to support cleaner processing and emissions control. Multiple safety interlocks on doors, over-temperature and power circuits to meet US safety norms and facilitate approval by local inspectors. Automation and MES connectivity Standardized interfaces for robots and roller conveyors at both inlet and outlet, enabling fully automatic loading and unloading of trays/fixtures. PLC and HMI designed to communicate with the plant’s MES: each batch’s temperature curve, hold time and recipe data are automatically recorded. Recipe management inside the Custom Heat Treatment Furnace allows quick switching between different component types without manual re-programming. Results: quality, energy and throughput all improved After commissioning and ramp-up, the US customer reported measurable improvements: More stable heat-treated quality Hardness values and case depths for gears and shafts became much more consistent across batches. Rework due to out-of-tolerance heat treatment dropped significantly. Lower unit energy and labor cost Despite the 580kW installed capacity, optimized insulation and control cut energy consumption per finished part compared to the old box-type furnace. At the same time, manual handling was largely removed, allowing operators to supervise rather than constantly intervene. Better line balance and shorter lead time Continuous flow through the Tube Type Heat Treatment Furnace now matches the cycle time of upstream machining and downstream washing and inspection, reducing WIP and improving overall delivery speed. The plant has since positioned this Custom Heat Treatment Furnace as a template for future line upgrades and is considering similar configurations for new production cells dedicated to higher-value components.

1. Project background: sensitive aluminum prices, unstable ingot output This Russian scrap aluminum recycling company mainly collects scrap from car dismantling and machining shops, melts it, and sells aluminum ingots to local aluminum die casting plants and export customers. However, their original small casting line had several serious weaknesses: Unstable hourly output – manual pouring and a short casting line made the real capacity fluctuate a lot, especially under rush orders. Non-standard ingot sizes – different molds and inconsistent pouring caused size variation, which made stacking, palletizing and container loading inefficient. Insufficient cooling and internal stress issues – because the line was short and cooling was not well controlled, some ingots showed surface shrinkage and hidden internal stress, and die casting customers were not fully satisfied. The management wanted a standardized 9m Aluminum Ingot Casting Machine line that could stabilize 2–3 tons per hour and produce ingots that meet both the Russian market and export packaging standards. 2. Solution: 9m Aluminum Ingot Casting Machine with 2–3t/h continuous casting Based on the customer’s furnace capacity and plant layout, we supplied a 9m Aluminum Ingot Machine / Aluminum Ingot Casting Machine as a complete casting line: 2–3 tons per hour design capacity The line was engineered for a continuous casting rate of 2–3t/h, matched to the output of the existing melting and holding furnaces. This avoids situations where the furnace is waiting for the line or the line is waiting for molten metal, making production planning and shift assessment much easier. Ingot molds customized to Russian die casting habits Mold dimensions were designed according to sizes commonly used by Russian aluminum die casting plants. This makes it easier for their automatic de-palletizing and charging systems, and at the same time helps the recycler create standard pallets with higher storage and container loading efficiency. Automated pouring, cooling, de-molding and ingot flipping The 9m ingot casting machine handles automatic pouring, vibration cooling, de-molding and flipping of ingots. Operators mainly supervise and handle strapping/packing instead of doing heavy manual pouring. For Russian companies facing rising labor costs and a shortage of skilled furnace operators, this reduction in manual dependence is a major advantage. 3. Results: from “scrap collector” to “stable aluminum ingot supplier” After commissioning, the Russian customer saw clear benefits: Stable 2–3t/h output of standard ingots – they can now commit to more long-term contracts without frequently pushing back delivery dates due to unstable capacity. Uniform ingot size and neat stacking – pallets are cleaner, container loading is faster, and the company has a stronger position when negotiating with local and export buyers. Business role upgrade – instead of being seen only as a scrap collector, the company is increasingly recognized as a “reliable aluminum ingot supplier” in the local aluminum die casting supply chain.
