Furnace Refractory Monitoring

Detecting refractory brick erosion and cracks early, so relining is planned on real wear.

01 / The Challenge

Refractory Wear You Cannot See

Refractory wear decides furnace campaign life, but from outside it is invisible until a red spot or failure appears.

Plants needed a way to measure brick condition while the furnace stayed hot, instead of guessing on a fixed schedule.

02 / What We Detect

Refractory Conditions

Brick Erosion

Gradual loss of refractory thickness and uneven wear.

Cracks

Thermal-stress cracks and expansion damage.

Spalling

Localised peeling before major failure.

Slag & Deposits

Build-up affecting heat distribution.

Hot Spots

Local thin zones and abnormal temperature.

Deformation

Geometry changes in the lining.

03 / Approach

How We Monitor

1

Access

Use an existing port near the area of concern.

2

Inspect

View the brick line and surface condition live.

3

Compare

Track wear against previous inspections.

4

Plan

Provide references for relining decisions.
