01 · Requirement Review
Check process inputs, acceptance criteria, site constraints and system interfaces.
ENGINEERING & MANUFACTURING
One engineering logic from process objective to operating system
Process, structure, heat transfer, electrical engineering and software must work together and connect correctly to the customer’s infrastructure.
WORKFLOW
Engineering Workflow
02 · System Concept
Establish the process route, equipment, atmosphere, heating, cooling and material handling concept.
03 · Thermal & Mechanical Engineering
Calculate thermal loads and develop the mechanical design; apply simulation where a defined engineering question justifies it.
04 · Electrical & Controls
Develop the control architecture, interlocks, HMI, recipes and data exchange with the line.
05 · Manufacturing & Assembly
Manufacture and assemble against project documentation and the agreed project quality plan.
06 · Installation & Commissioning

DIGITAL PROCESS ENGINEERING
Bell-Furnace Annealing Cycle Generator
Transforms material, coil-loading and furnace conditions into a review-ready annealing cycle recommendation, with temperature profiles, cycle time and load estimates in one engineering view.
Operating Data
Enter material grade, furnace type, coil dimensions, coil count, density, target cooling temperature and cooling rate.
Process Matching
Match the duty to relevant process records, candidate annealing schedules, furnace configurations and load platforms.
Cycle Generation
Generate staged heating, soaking and cooling profiles for both control temperature and coil-core temperature.
Engineering Output
Review estimated cycle time, load calculation, matching basis and a detailed time-temperature schedule, with CSV export.
Outputs are intended for equipment selection and technical discussion only. The final annealing cycle must be confirmed against the material, load arrangement, furnace configuration and project acceptance requirements.
