ERP for Integrated Steel Plants
ZapNexa tracks material and money from the purchase order to the GST invoice. Vexron watches the machines that stop the factory when they fail.
What is an ERP for the steel industry?
An ERP for the steel industry tracks material and money through the whole factory in one system: raw material weighed in, coke and power used at the furnace, heat-wise chemistry from the lab, billet yield at the caster and mill, and finished steel invoiced and dispatched. It replaces shift registers and spreadsheets with one set of numbers.
An integrated steel plant moves very large tonnages through a chain of hot processes. Iron ore, coal and fluxes come in by truck and rail. The blast furnace makes hot metal. The melt shop turns it into steel of a set grade, the caster makes billets or slabs, and the rolling mill turns those into bars, sections or coils. Every step loses some material and uses a lot of energy.
That is why steel is hard for a general-purpose ERP. The money is in the details: how much coke went into each tonne of hot metal, which heat a billet came from, how many tonnes were lost as scale or miss-rolls. If those numbers are written in a register and typed into a spreadsheet at the end of the shift, cost per tonne is always a few days late and nobody fully trusts it.
ZapNexa is a manufacturing ERP that covers most of this: production orders with consumption and scrap, batch genealogy, power meters by work centre, quality checks, dispatch with GST e-invoices, and books for several plants. Furnace-specific records, such as coke rate or lab chemistry by heat, are not standard modules today. Vexron sits next to it on the maintenance side, so a planned stop is a planned cost and not a surprise.

What an ERP for a steel plant must handle
Use this table as a checklist. Each row is a stage of the factory, the data an ERP should capture there, and where it lives in ZapNexa or Vexron.
- 1Raw material receipt
- 2Blast furnace
- 3Melt shop
- 4Continuous caster
- 5Rolling mill
- 6Dispatch
- 7Finance and multi-plant
- 8Maintenance
| Stage | Data the ERP should capture | Where it lives |
|---|---|---|
| Raw material receipt | Truck and rail weights, supplier, grade, lab results on arrival | Purchase order, goods receipt with incoming checks (ZapNexa) |
| Blast furnace | Hot metal output, coke and fuel consumed, furnace logs | Production orders with material consumption, power readings (ZapNexa) |
| Melt shop | Heat number, heat-wise chemistry, grade made | Batch numbers, inspection results against specification limits (ZapNexa) |
| Continuous caster | Billets or slabs per heat, weights, rejects | Production output, rejects and scrap with reason (ZapNexa) |
| Rolling mill | Billet-to-bar output, burning loss, miss-rolls, bundles | Routings, scrap with reason, batch genealogy, barcode labels (ZapNexa) |
| Dispatch | Bundle and coil weights, truck weights, invoices | Delivery, e-way bill and GST e-invoice (ZapNexa) |
| Finance and multi-plant | Cost per tonne, P&L by factory, stock moved between factories | Finance, multi-company consolidation (ZapNexa) |
| Maintenance | Vibration, temperature and power on critical drives, fans and pumps | Predictive maintenance (Vexron) |
Common problems
Where steel plants lose money without noticing
These problems are common in factories that still run on registers and spreadsheets.
Weights typed in by hand
Raw material and dispatch weights are copied from the weighbridge slip into a register, then into the system. Every copy is a chance for an error that nobody finds until stock does not match.
Yield known only at month end
Billet-to-bar yield, burning loss and miss-roll scrap are worked out in a spreadsheet after the month closes. By then the shift that caused the loss is long gone.
Chemistry and production in different places
The lab keeps heat-wise chemistry in its own book. Linking a customer complaint back to the heat that made the steel takes hours of searching.
Coke and power per tonne are estimates
Coke and power are large costs, but they are often shared out by formula instead of being measured against each day's output.
A drive failure stops the line
When a caster or mill drive, a gearbox or a large fan fails without warning, the whole line waits. The repair is often cheaper than the lost hours.
ERP
What ZapNexa does in a steel plant
Each module below runs on live production data, so finance and production read the same numbers.
Production orders and costing
Bills of materials and routings, with material consumed, output and scrap booked against each order. Cost rolls up into material, labour, machine and overhead.
Batch genealogy
Traces a finished batch back to the raw material batches that went into it, and forward to the customer who received it.
Quality checks
Inspection plans with specification limits and sampling, SPC charts, certificates of analysis per batch, and NCR and CAPA when something fails.
Power per tonne
Energy meters on work centres and machines, read by hand or through an edge gateway, show kWh and cost per unit produced by day.
Maintenance and machines
Preventive maintenance, downtime reasons, OEE from machine counters, and calibration of instruments.
Finance, GST and multi-plant
E-invoices, e-way bills and GST returns, with consolidated reports and stock transfers across factories and branches.
Predictive maintenance
ERP plus predictive maintenance
An ERP tells you what a stop cost. Vexron helps you avoid the stop. It reads the PLC and sensor data your factory already has, learns how each machine normally runs, and warns your team when a fault starts to develop.
Caster and rolling mill drives
Watches drive motors, gearboxes and spindles, where mould oscillation, guide roll wear and spindle torque show up as changes in the signal.
Fans, pumps and compressors
VMI-1 separates bearing wear, misalignment, imbalance and looseness instead of raising one generic alarm, and points to the signal behind each alert.
Slow wear on hot equipment
Longer-range forecasting models trend slow changes such as refractory wear and thermal drift over days, not seconds.
Downtime cost in rupees
Each stop is shown as lost money, so the maintenance plan and the CFO work from the same figure.
Checklist
Questions to ask any steel ERP vendor
Whoever you shortlist, ask these before you sign. The answers separate a steel ERP from a general one with steel words on the brochure.
- Do weighbridge weights flow in automatically, or does someone type them?
- Can the system carry a heat number from the melt shop to the dispatched bundle?
- Is yield calculated per heat or batch, including burning loss and miss-rolls?
- Is lab chemistry linked to the production record, or kept separately?
- Can it consolidate several factories and move stock between them?
- Can we start with one module and keep our current accounting for a while?
- Can machine health data sit next to production, so a planned stop has a known cost?

Support
A named engineer who already knows your installation.
Yes. ZapNexa is designed for multi-plant operations, with centralised reporting and stock transfers between plants.
Yes, through an edge gateway on the shop floor. Good and reject counts, run signals and energy readings come in over OPC UA, MQTT or HTTP, and ZapNexa turns them into OEE and power per unit.
Inspection plans hold each characteristic with its specification limits and sampling plan. Results are recorded against the batch, a certificate of analysis can be issued from them, and batch genealogy links a customer complaint back to the batch that made it.
Each production order books the material consumed, the output made and the scrap with its reason and cost, so yield comes from the order, not a spreadsheet. Cost rolls up into material, labour, machine and overhead.
Yes. Most clients move one module at a time, starting with the one causing the most pain. ZapNexa is designed to work alongside the accounting tools you already run, and some clients keep Tally running during the move.
It depends on scope. Most clients start with one factory or one module, prove it against real operating data, then extend to the rest of the factory once the team trusts it. That is usually faster and lower-risk than switching everything at once.
Vexron watches the machines whose failure stops production: caster and mill drives, gearboxes, fans, pumps and compressors. It reads the PLC and sensor data you already have and warns your team when a fault starts to develop.
