A specialty metals processor operating a heat treatment cell across two production shifts was absorbing energy waste and product quality inconsistencies that had no paper trail and no structured resolution path. Furnace soak cycles were running on fixed manual settings that had not been reviewed since initial commissioning — with technicians adjusting gas flow based on experience rather than logged performance data. Temperature deviations during long production runs were generating rework events, extended cycle times, and utility costs that plant leadership could not quantify or reduce without better operational visibility. After deploying Oxmaint's CMMS platform to digitize furnace inspection routines and maintenance scheduling — Sign Up Free to see how fast your heat treatment cell can reduce energy waste — the facility reduced gas consumption by 19%, stabilized soak cycle variance to within 2% of target, and cut heat treatment rework events by 58% within 90 days.

01 / The Facility
Specialty Metals Heat Treatment. Two Shifts. No Furnace Performance Data.
Facility Type
Specialty metals processor operating a dedicated heat treatment cell producing annealed, hardened, and tempered components for aerospace and industrial customer programs. Operations governed by AS9100 quality requirements with customer-mandated metallurgical traceability and process stability documentation.
Scale
Single facility, two production shifts. 8 industrial furnaces across three heat treatment process types — annealing, hardening, and tempering. Annual production spanning approximately 2.1 million treated components across customer programs with continuous cycle monitoring obligations.
Maintenance Team
6-person maintenance and process team — one maintenance supervisor, three furnace technicians covering mechanical and combustion disciplines, one process engineer responsible for cycle parameter management, and one administrative coordinator managing furnace logs and rework records.
Performance Baseline
Soak cycle variance of ±8% across the furnace fleet prior to deployment. Average of 7 rework events per month traced to temperature instability or cycle deviation. Monthly gas consumption trending 23% above industry benchmarks for equivalent throughput volume.
Prior System
Manual paper furnace logs, handwritten cycle parameter sheets, and clipboard-based shift inspection checklists. No structured PM scheduling for combustion system components. Rework events tracked in a shared spreadsheet without linkage to furnace operating data or cycle records.
Annual Overhead Exposure
Excess gas consumption above benchmark estimated at $112,000 annually at current throughput rates. Rework labor and material cost from heat treatment cycle deviations estimated at $78,000 per year. Combined energy and quality waste totaling approximately $190,000 against a facility operating with no structured furnace performance management system.
02 / The Challenge
Without Structured Furnace Data, Energy Waste and Quality Deviation Are Invisible Until They're Expensive
For a heat treatment cell producing metallurgically certified components, soak cycle stability is not an operational preference — it is a product quality requirement with customer traceability implications. When furnace parameters are managed through manual adjustment and paper logs, cycle deviations accumulate without triggering corrective action. Gas consumption climbs without a benchmark to flag it. Combustion system components drift past their service intervals because PM schedules are not connected to operational data. This facility's energy waste and quality variance were not the result of poor technician judgment — they were the predictable outcome of a heat treatment operation with no structured visibility into furnace performance between shift-end log entries. Book a Demo to see how Oxmaint's digital inspection and PM platform closes these visibility gaps in heat treatment environments.
±8%
Soak cycle variance
Furnace soak cycles running on fixed manual settings without structured monitoring produced variance that was invisible until it generated rework — with no alert system to flag drift before product quality was affected.
7 events/mo
Monthly rework events
Seven rework events per month traced to heat treatment cycle deviations — each requiring full re-processing of affected components, customer notification for certified programs, and manual documentation of root cause without reliable furnace operating data to support the analysis.
+23%
Gas consumption above benchmark
Monthly gas usage running 23% above industry benchmarks for equivalent throughput — driven by combustion inefficiency from unmaintained burner components, suboptimal soak temperature control, and extended cycle times from manual setpoint management.
$190K
Annual energy and quality waste
Combined excess gas cost and rework labor and material totaling $190,000 annually — entirely driven by furnace performance management gaps that structured digital PM scheduling and inspection checklists could systematically eliminate.
"We knew the furnaces weren't running right, but we had no data to show where. The technicians were making good decisions with bad information — and the gas bill and rework log were telling us something was wrong long after we could act on it."
03 / The Solution
Oxmaint CMMS: Digital Furnace PM Scheduling, Inspection Checklists, and Asset Performance Tracking for Heat Treatment Operations
After evaluating maintenance management options against the facility's furnace performance and energy reduction requirements, the process engineer and plant manager selected Oxmaint for its structured PM scheduling, digital inspection capabilities, and asset performance tracking that aligned with existing furnace classification and maintenance practices. The priority was not a complex energy management system — it was giving technicians and supervisors the structured inspection and PM data needed to identify where performance was degrading before it generated rework or inflated the utility bill. Sign Up Free and configure your first furnace PM schedule in under a day.
FURNACE PM
Preventive maintenance schedules configured per furnace, combustion system component, and service interval — with automated mobile alerts dispatching PM work orders before burner tune-up, thermocouple calibration, and refractory inspection windows expired. Combustion efficiency PM compliance replaced verbal scheduling that routinely deferred burner service past recommended intervals.
INSPECTIONS
Digital inspection checklists deployed for shift-start furnace condition walkthroughs, soak cycle parameter verification, and combustion system observation rounds — replacing clipboard forms with structured mobile checklists that auto-generated work orders when temperature readings or gas pressure observations fell outside defined operating thresholds.
ASSET HISTORY
All 8 furnaces catalogued into a structured digital registry with QR-tagged profiles containing combustion service history, manufacturer intervals, thermocouple calibration records, and technician parameter notes — giving every team member complete furnace context at the point of inspection without locating paper logs or contacting the coordinator.
WORK ORDERS
Digital work order creation replaced paper furnace logs and manual rework records across both shifts. Every work order captured furnace ID, cycle parameters at deviation, technician observations, corrective actions taken, and post-correction verification readings — building the operational data history that enabled systematic furnace tuning decisions.
REPORTING
Supervisor dashboards providing real-time visibility into open work orders, PM compliance by furnace, rework event frequency, and asset downtime accumulation — giving the process engineer the structured data needed to identify cycle parameter optimization opportunities and support customer-mandated metallurgical traceability documentation.

06 / Key Business Impact
What Structured Furnace PM and Digital Inspection Protected Beyond Energy Savings
01
The 23% gas consumption excess above benchmark was not a process design problem — it was a combustion PM compliance failure. Burner components operating past their service intervals consumed more gas to maintain target temperatures, and thermocouple drift caused controllers to compensate with excess heat input. Oxmaint's structured PM scheduling restored combustion efficiency by ensuring every component was serviced within its certified interval.
02
Seven monthly rework events were a product quality cost that paper logs could not connect to specific furnace operating conditions. Oxmaint's digital inspection records captured temperature readings, gas pressure observations, and cycle parameters at the point of deviation — giving the process engineer the furnace-specific data needed to trace rework root causes and eliminate them at the source.
03
Soak cycle variance of ±8% created metallurgical inconsistency across production runs that customers with AS9100 traceability requirements could not accept. Stabilizing variance to within ±2% through structured combustion PM and digital parameter verification directly supported customer-mandated quality documentation and reduced the frequency of hold and review events on certified component programs.
04
The administrative coordinator recovered 31 hours per month previously spent transcribing paper furnace logs into the rework spreadsheet — redirected toward customer metallurgical traceability package preparation and capital planning support for furnace fleet renewal. The process engineer gained access to structured per-furnace performance data for the first time without requesting manual log retrieval from the coordinator.
