Steel Production
Testing your mettle
We know you’re under pressure to produce flawless steel for automotive, appliance and other demanding applications. From strip tracking and pickup to abrasion and profile/roughness loss, you face critical roll surface issues every day. Daily wear can be reduced with our advanced thermal spray coatings and laser weld overlays. Our coatings keep your rolls running at peak performance.
Furnace Rolls
Are you experiencing oxide pickup, wear from abrasion, slippage or speed mismatch, or excessive dross buildup on your roll surface that impacts strip quality? Our ceramic-metallic thermal spray coatings can help. These coatings protect against abrasive wear, pickup, loss of surface roughness and profile. And we offer a turnkey service if your furnace rolls need repair or replacement restoration.
Pot Rolls with a Chrome-Free Sealer
Our next-generation chrome-free pot roll coating sealant lessens dross adhesion for hot-dip coating lines that produce galvanized and galvannealed-coated steels. This sealant penetrates the coating surface, creating a chemical bond to the underlying carbide coating for superior adhesion and preventing dross particle buildup in molten baths. By limiting dross adhesion on pot rolls, steel mills can boost productivity by making higher-quality steel with less waste. Our coating and sealant system is kind to the environment but tough on dross adhesion.
