REDUCED HEAT LOSS TO COOLING WATER

Cooling water is a major source of heat loss for rolling mills. KA-Weld® insulation modules reduce heat loss to the cooling water in your pipe support structure up to 95%. Less heat is lost to your cooling water, so less heat is needed for your furnace.

Performance for Varied Operating Environments

Each KA-Weld® family product is designed for varying degrees of thermal performance and mechanical durability, depending on operating conditions within the furnace environment. Please see the drawing below for details.

OPTIMISED INSULATION PERFORMANCE

Today, in response to increased energy costs around the world, HOTWORK offers a family of pre-cast and modular insulating shapes optimised for superior thermal performance and mechanical durability. Our family of insulation products is designed to withstand the demands of every support structure environment, from the most passive to the most severe.

HIGH EFFICIENCY ALTERNATIVE TO CAST-IN-PLACE

Missing sections of cast-in-place insulation are often difficult, unless impossible, to replace. Heater shutdowns, bulky moulds, complex setup routines and long furnace dryouts required by cast-in-place systems are expensive, both in installation costs and lost production. KA-Weld® modules change all that.

FAST, EASY INSTALLATION

KA-Weld® modules arrive at your plant ready to install. KA-Weld®’s uniformly size modules facilitate easy repair of both large areas and hard to reach spots. Easy installation by bolting, welding or interlocking greatly simplifies the repair/rebuild process.

ROI MEASURED IN DAYS

Many KA-Weld® installations make a full return on investment, by means of fuel savings, within a few production cycles. For most rolling mill operators that means their KA-Weld® investment pays for itself in a matter of days.

Improved Maintenance

Due to their manageable size, light weight, and ease of installation, KA-Weld® modules facilitate more thorough and more frequent maintenance and repair routines, resulting in higher operating efficiencies and fewer emergency shutdowns. In some cases, sport repairs can be made without furnace shutdown. For more extensive repairs or rebuilds, shutdown times are much shorter than with cast-in-place systems.

Wide variety of shapes and formulations

KA-Weld® modules are available in virtually any formulation and shape you need. Straights, caps, tees, returns and many more. Formulations range from 40 to 98% alumina.

Reduced Emissions

Today’s regulatory environment imposes strict emissions controls. A valuable side effect of reduced fuel use is reduced emissions of nitrous oxides and carbon compounds. KA-Weld® modular shapes are both financially and environmentally friendly.
