Heat-Resistant Insulation and Sealing for Steel Mill Reheat Furnaces and Rolling Lines

A steel mill’s reheat furnace runs around the clock at temperatures most industrial insulation was never designed for, and the rolling line downstream combines heavy mechanical load with abrasive scale. Both problems come down to specifying materials rated for the real conditions, not the nearest generic grade.

Furnace lining that survives continuous cycling

Ceramic Fiber Wool is classified to 1260°C with low heat storage, so the furnace heats and cools faster on each cycle — a real fuel saving over a full campaign. Where the lining needs to be rigid and resist gas erosion in high-velocity zones, Ceramic Board holds up better than blanket.

Abrasion-resistant packing for mill equipment

Mica Packing was built specifically for this environment — its stainless-steel wire reinforcement gives it the abrasion resistance that ordinary packing lacks when handling scale-laden, high-temperature rolling equipment.

Protecting workers and equipment from radiant heat

Vermiculite Coated Silica Cloth withstands continuous temperatures around 1000°C, making it the standard choice for heat screens and covers near furnace openings and hot rolling stands.

Drive brakes under heavy, continuous load

Rolling mill drives and auxiliary equipment brakes need a friction lining that doesn’t fade under repeated heavy braking. Non-Asbestos Woven Brake Lining holds a stable coefficient of friction for exactly this duty.

Frequently asked questions

How often should reheat furnace lining be inspected? At every scheduled shutdown at minimum — lining that looks intact can have lost density internally, reducing its insulating value well before it visibly fails.

Can ceramic board and blanket be used together? Yes — board is often used as a hot-face layer with blanket as backup insulation behind it, combining rigidity with low heat storage.
