Metallurgy electrical automation from Danli: HV, MV and LV power distribution, intelligent motor control and digital monitoring for steel and non-ferrous metal plants.
Given the characteristics of the metallurgical industry, challenges exist in areas such as operations management, asset management, energy conservation, and meeting the high safety and reliability requirements of electrical equipment. The power distribution system in the metallurgical industry needs to support digital upgrades, enhance safety and reliability, and reduce energy consumption to improve efficiency.
Steel works, aluminium smelters, rolling mills and foundries run large motors and furnaces around the clock in hot, dusty and electrically noisy conditions. Unplanned outages are costly, and energy is one of the biggest operating expenses. Reliable power distribution and well-designed motor control are therefore central to safe and profitable production.

| Iron and steel making | Furnace auxiliaries, cooling water pumps, dust extraction fans | MV/LV switchgear, VFDs for large fans and pumps |
| Rolling and finishing | Mill auxiliaries, roller tables, coolers | LV distribution, motor control centres, drive panels |
| Utilities | Compressors, water treatment, cooling towers | Switchgear, MCCs, PLC/SCADA |
Motors drive most of the process in a metal plant, from conveyors and pumps to large induced-draft fans. We offer the full range of starting and control methods — direct-on-line starters with contactors and thermal or electronic overload relays, soft starters, and variable frequency drives — packaged in withdrawable or fixed MCCs. Intelligent motor protection relays report current, temperature and trip history to the control system, helping maintenance teams find problems before they cause breakdowns.
Online monitoring of switchgear temperature, breaker operation and motor condition turns maintenance from fixed intervals into condition-based planning. Energy meters on each feeder show consumption by process area, supporting energy-efficiency programmes and cost allocation. All data can be brought into a single SCADA or energy management platform.
Typical monitored values include busbar and cable joint temperatures, breaker operation counts and trip records, motor current and running hours, and power quality indicators such as harmonics and voltage dips. Alarms and trends help plant engineers plan work during scheduled stoppages instead of reacting to failures during production.
From a single MCC replacement to the complete electrical package for a new production line, Danli designs, builds and tests switchgear, motor control and automation cabinets together so interfaces are coordinated. Related products: high-voltage switchgear, low-voltage switchgear, VFD cabinets and PLC/DCS cabinets.
Electrical faults in a metal plant can stop a whole production line and put people at risk. We design for selective protection, so the breaker nearest a fault clears it without tripping upstream feeders, and for internal arc safety in switchgear rooms that operators enter regularly. Duty/standby arrangements on cooling water pumps and other critical services, redundant control power and clear interlocking between process and electrical systems help keep the plant running safely.
Typically medium voltage switchgear and transformers, low voltage switchboards, motor control centres, VFDs for large fans and pumps, PLC or DCS control systems and power-quality equipment such as filters and capacitor banks.
VFDs cut the energy used by fans and pumps that run below full load, reduce starting stress on motors and supplies, and allow precise speed control of process equipment.
By derating components, choosing suitable enclosure ratings, using filtered or air-conditioned cooling, and locating sensitive equipment in protected electrical rooms where possible.
Yes. MCCs can be replaced section by section, with factory-tested equipment and planned changeovers to keep downtime short.
From a single control cabinet to full plant-wide automation.
