DAVY MCKEE Product Lines We Repair
Our engineers are trained on the full DAVY MCKEE product range. Below are the major product families we service.
Casting Control Systems (CCS)
Davy McKee's integrated continuous casting automation platforms controlling mold oscillation, spray cooling, and ingot formation. Common faults include sensor calibration drift, oscillation frequency errors, and thermal compensation failures in multi-zone casting systems.
Rolling Mill Control Units (RMCU)
Heavy-duty electrical controllers for hot and cold rolling mills, managing stand coordination, load distribution, and pass scheduling. Repair issues centre on position feedback sensor faults, load cell signal conditioning, and coordinated motor control logic failures.
Metallurgical Temperature Monitoring (MTM)
Specialised analogue and digital temperature measurement systems for ladle, tundish, and furnace monitoring. Common faults include thermocouple interface degradation, signal linearisation errors, and alarms failing to trigger at setpoint.
Foundry Automation Platform (FAP)
Integrated control systems for sand casting, metal pouring, and mold handling automation. Typical failures involve servo valve responsiveness loss, flow meter accuracy degradation, and sequence logic hangs during pour cycle execution.
Legacy Relay & Contactor Systems
Older Davy McKee installations using electromechanical control logic, hard-wired safety interlocks, and pneumatic actuators. Restoration involves relay contact burnishing, solenoid coil rewinding, and failsafe circuit recommissioning.

Common DAVY MCKEE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DAVY MCKEE equipment arriving at our workshop.
- ✓Casting mold oscillation stops or becomes erratic — Davy McKee CCS systems rely on precise frequency synchronisation between electrical driver and mechanical linkage. Bearing wear in the drive mechanism, capacitor aging in the frequency control circuit, or loss of encoder feedback from the mold motion transducer causes oscillation failure. Common in mills operating 15+ years without motor bearing replacement.
- ✓Temperature sensor reads 50-100 degrees lower than actual metal temperature — Davy McKee MTM thermocouple interfaces suffer from cold-junction compensation drift and connector oxidation in high-humidity foundry environments. Solder joints in the thermocouple breakout cards fracture under thermal cycling. Linearisation tables stored in EEPROM become corrupted after power surges.
- ✓Rolling mill stand does not coordinate load across dual motor drives — Davy McKee RMCU systems synchronise two large motors through a master-slave load-sharing algorithm. Failure occurs when load cell signal conditioning amplifiers develop offset drift, CAN-bus communication frames drop due to EMI, or the proportional solenoid valve response becomes sluggish from silt accumulation in the hydraulic circuit.
- ✓Foundry pouring sequence hangs at mid-cycle, requiring manual reset — Davy McKee FAP legacy ladder-logic firmware executes pouring sequences through timed outputs and sensor polling. Hangs occur when inductive proximity switch sensing becomes intermittent due to corroded wiring, PLC scan time exceeds 100 ms due to program memory fragmentation, or the watchdog timer circuit fails to reset the processor after a logic timeout.
- ✓High-temperature furnace control loses setpoint stability and oscillates ±30 degrees — Davy McKee MTM systems use analogue PID controllers tuned during commissioning; loop instability emerges when heating element resistance increases with age, or feedback signal noise increases from loose shielding. Calibration drift in the PID potentiometers after thermal cycling destabilises proportional band and integral gain.
- ✓RMCU displays error code E47 - Load Cell Signal Out of Range — Davy McKee RMCU firmware triggers E47 when load cell millivolt output falls outside expected band (typically 10-60 mV). Root causes include broken load cell cable, failed signal conditioning amplifier, or incorrect excitation voltage (should be 10V regulated DC). Mills often ignore E47 and continue operation, masking upstream failures.

Frequently Asked Questions — DAVY MCKEE Repairs
Do you repair Davy McKee equipment anywhere in India?+
Yes. Synchronics repairs the full Davy McKee metallurgical and casting equipment range across all Indian steel and foundry plants. We offer PAN India door pickup from Mumbai, Delhi, Pune, Ahmedabad, Vadodara, Nagpur, Bangalore, Chennai, Hyderabad, and all other industrial cities. All repairs are processed at our main facility in Vadodara, Gujarat, with typical turnaround of 5-7 working days for standard electrical faults.
How do I diagnose a Davy McKee casting control system failure?+
Start by checking the PLC/controller display for error codes (e.g., E47, E52 for sensor faults). Verify 24V power supply and encoder signal presence using a multimeter. Listen for relay clicking in the electrical cabinet - silence indicates contactor or solenoid failure. If you have oscillation loss, measure frequency at the motor drive terminals. Synchronics offers free remote diagnostics: send photos of the error display and electrical cabinet, or call our hotline with a description, and we will advise if repair is urgent. Most Davy McKee failures can be partially diagnosed without removing equipment.
What is the typical lead time for Davy McKee spare parts in India?+
Original Davy McKee spare parts are difficult to source in India due to the company's UK heritage and legacy product focus. Synchronics maintains a stock of common replacement components: EEPROM chips, electrolytic capacitors, thermocouple connectors, load cell interface cards, and relay modules. For electronics, we source equivalents from approved suppliers and re-code to match Davy McKee firmware specifications. For OEM parts, expect 4-8 weeks via European distributors. Always contact us before ordering - we often have in-stock alternatives that avoid delays.
Can Synchronics retrofits older Davy McKee relay-based control systems with modern PLC logic?+
Yes. Many SAIL and Tata Steel mills still operate Davy McKee legacy relay and pneumatic systems installed in the 1990s. Synchronics performs controlled retrofits: we map the original hard-wired logic into IEC 61131-3 structured text, implement the sequence on a modern compact PLC (Siemens S7-1200 or similar), and integrate new sensor interfaces while preserving the existing motor drives and solenoid valves. This approach eliminates downtime for complete system replacement. We handle all safety interlock certification and provide 12 months of firmware support post-retrofit.
Do you offer predictive maintenance or condition monitoring for Davy McKee equipment?+
Synchronics offers annual health checks for Davy McKee casting and rolling mill systems. During a 2-4 hour visit, we measure PLC program scan time, perform load cell signal quality analysis, inspect all connector pins for oxidation, and test soft-start capacitors and power supply regulation. We generate a detailed report with criticality ratings for each component and recommend spare parts inventory. For mills with chronic failures, we can install permanent temperature and vibration sensors on critical drives to flag bearing wear before failure. Contact our service team to schedule an audit.
How do I send my DAVY MCKEE unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a DAVY MCKEE drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on DAVY MCKEE repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your DAVY MCKEE unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
