Successful Shipment of 30T Gantry Frame Electroslag Furnace by Shanghai Vacuum Melting Technology Co., Ltd.Ingenuity forges heavy equipment; strength opens new chapters! Recently, the newly upgraded 30T gantry frame electroslag remelting furnace independently developed by Shanghai Vacuum Melting Technology Co., Ltd. has completed overall commissioning and quality acceptance, and is fully prepared for smooth delivery to Baowu Special Metallurgy. As a benchmark core equipment for high-end special metallurgical production, this furnace integrates a number of proprietary core technologies, focusing on four key advantages: high precision, high stability, high purity and low energy consumption. It precisely addresses industry pain points of traditional electroslag furnaces, such as unstable operation, impure steel quality and poor process controllability, fully helping customers improve quality, efficiency and achieve high-end upgrading of special material production lines.
The equipment adopts a high-rigidity gantry frame structure, which is the cornerstone for stable operation of large-tonnage electroslag furnaces. The integrally forged structure features strong load-bearing capacity and sufficient rigidity, effectively avoiding deformation and offset under long-term heavy-duty operation, and greatly improving operation accuracy and service life. Compared with traditional frame structures, its anti-vibration and anti-shock performance is significantly optimized, perfectly adapting to continuous remelting production of 30T large-sized steel ingots with stable and reliable operation throughout the process, laying a solid hardware foundation for large-scale and standardized metallurgical production. In terms of energy efficiency and quality optimization, the furnace is equipped with a copper shaft conductive system, realizing an innovative integrated design that combines the copper shaft conductive circuit and the equipment load-bearing circuit. This makes the structure more compact, the layout more concise and the overall operation more stable, achieving a leapfrog improvement in metallurgical energy efficiency. Different from traditional split structures, the integrated design reduces redundant components, line losses and structural failure points. Meanwhile, the low-impedance transmission design effectively lowers current circuit loss, optimizes magnetic field distribution and offsets electromagnetic interference. It not only greatly improves power utilization and reduces per-ton steel production cost, but also optimizes molten pool conditions, reducing defects such as composition segregation and uneven microstructure in steel ingots. Each batch of steel ingots features more balanced performance and more consistent quality, realizing the dual values of energy saving, efficiency improvement and product quality enhancement. To meet the high-purity production requirements of high-end alloys and special steel materials, the equipment is equipped with a fully enclosed protective atmosphere smelting system. Full-process inert gas sealing completely blocks the intrusion of oxygen, nitrogen, hydrogen and other impurities from the air, effectively suppressing the burning loss of easily oxidizable alloy elements during smelting. It precisely controls impurity content in steel ingots, significantly improving molten steel purity and material compactness, meeting the stringent production standards for high-end die steel, bearing steel, superalloys and other high-precision special materials. In terms of intelligent control, the furnace is equipped with a constant melting rate + pressure swing dual closed-loop intelligent control system, enabling precise and controllable smelting processes. Relying on high-precision sensing modules and proprietary algorithms, the equipment can dynamically monitor and accurately adjust electrode melting speed and slag pool pressure swing in real time, stabilizing molten pool heat input. It thoroughly solves problems such as melting rate fluctuation and unstable processes in traditional smelting, standardizing and refining the smelting process, ensuring high consistency of product quality in mass production and greatly improving the finished product pass rate. In addition, the equipment is equipped with a dedicated heated water tank system to overcome production challenges in humid working conditions. The constant-temperature heating function of the water tank fundamentally eliminates the hidden dangers of mold condensation and water accumulation in high-temperature and high-humidity environments in summer, preventing condensed water on the mold surface from entering the molten pool. This effectively avoids excessive increase of oxygen, nitrogen and hydrogen content in electroslag ingots, drastically reducing defects such as blowholes and porosity in cast ingots. It comprehensively ensures the compact and pure internal structure of electroslag ingots, greatly improving the yield rate, enabling the equipment to adapt to various complex temperature and humidity workshop conditions and achieve stable and high-quality production around the clock.
Deeply engaged in the field of special metallurgical equipment, Shanghai Vacuum Melting Technology Co., Ltd. always takes technological innovation as the core and customer demand as the orientation. The successful shipment of this 30T high-end electroslag furnace not only fully demonstrates the company’s strong R&D and manufacturing strength, but also represents a new breakthrough in the high-end metallurgical equipment market. In the future, Shanghai Vacuum Melting Technology Co., Ltd. will continue to refine core technologies and optimize equipment performance, empowering more manufacturing enterprises with high-quality, intelligent and energy-efficient metallurgical heavy equipment to achieve iterative upgrading, and promoting the high-quality development of the special metallurgy industry. |
