Refractory Quality Control and Inspection
McKeown's refractory quality control program checks supplied products at every stage of production, so what arrives at your plant matches what you specified, both on paper and in the brick.
Since 1989
McKeown has trained supply partners in statistical process control
A Quality Program With Decades Behind It
McKeown launched its first supplier quality program in 1989 to train refractory manufacturers in statistical process control and bring their output in line with Western quality standards. That program continues today. It holds partner-made products to McKeown's design standards and to your own specifications, and it's also available as a third-party inspection service.
Inspection at Every Stage of Production
-
01
Raw Material
We verify supplier chemical and physical reports, then sample and test incoming material against your requirements.
-
02
Crushing and Mixing
Periodic sampling checks grain composition, chemical content, moisture, and mixing time.
-
03
Mould
Before pressing, mould dimensions are checked against the engineering drawings.
-
04
Firing
Maximum temperature and time at temperature are monitored for every firing.
-
05
Finished Product
Surface defects, dimensional tolerances, classification, and marking are inspected, with pre-assembly before shipment when required.
-
06
Packaging and Marking
Pallets are checked for correct labeling and compliance with international wood-packaging (IPPC) rules before release.
Specialized Testing and Equipment Inspection
Some products need more than a visual and dimensional check. Our inspectors witness electrical conductivity, hardness, and computerized taper testing on copper molds, and they inspect fabricated process equipment for engineering specifications, welding certification, shop testing, final assembly, and shipping.
Documented Before It Ships
Every inspected order closes with an inspection report that compares manufacturer certificates against the specification, records physical and visual findings, and approves the shipment. You see the evidence before the goods leave the partner facility.
