Commissioning software for smelters and refineries where furnace refractory curing, matte tapping and the electrowinning cellhouse all have to be proven before the first metal is cast.

Furnace refractory curing follows a temperature ramp defined by the refractory manufacturer down to the degree per hour, running over days or weeks, and every deviation has to be logged and justified because a rushed curve is not a delay, it is a latent failure that shows up as refractory spalling months into production.

Downstream of the furnace, the converter and casting circuit, and the electrowinning or electrorefining cellhouse with its thousands of cells, are commissioned by different specialist teams on different timelines, with cell-by-cell current efficiency data often sitting in a metallurgical lab system nobody else can see.

Deskely puts the furnace heat-up curve, the converter circuit and the cellhouse in one register with one status model, so first-metal readiness is read from signed thermal and electrical records instead of reconstructed from separate specialist reports under deadline pressure.

First matte or blister tapping is recorded against the furnace with tap temperature, composition and tapping duration captured, alongside the converter's readiness to receive the tap, so the interface between two circuits commissioned by two different teams is proven together rather than assumed.

Electrowinning or electrorefining cellhouse energisation is staged cell by cell, with current efficiency, cell voltage and short-circuit checks recorded per cell, so a small number of underperforming cells are identified and corrected before the whole cellhouse is declared at rated current.

Open findings from furnace commissioning, converter interface testing or cellhouse energisation stay attached to the specific asset with an owner, so a refractory hot spot or a shorting cell is tracked to resolution rather than noted and forgotten once metal is flowing.

Furnace off-gas carries sulphur dioxide, particulate and heat that has to pass through a gas cooling and cleaning train — waste heat boilers, electrostatic precipitators or baghouses, and in many smelters a sulphuric acid plant — before it reaches a stack that a regulator has set a hard emission limit against, and none of that gas train can be proven without the furnace actually running.

Commissioning the gas cleaning circuit therefore happens in the same window as first tapping, under time pressure, and a baghouse bag failure or an acid plant conversion efficiency shortfall discovered during the first heat can force a furnace to be turned back down before refractory curing is even complete, at direct cost to the curing schedule.

Deskely tracks precipitator and baghouse functional testing, acid plant conversion and absorption efficiency trials, and continuous emissions monitoring calibration against the same register as the furnace heat-up curve, so first-metal readiness and environmental permit compliance are reported from one evidence base instead of the environmental team discovering a gap only once the stack is already live.
