Thermal and cooling

Printable Version

Fives proposes a range of proprietary thermal and cooling solutions for strip processing lines, such as Stein Digiflex® furnace and FlashCooling® technology for vertical annealing and galvanizing lines to process advanced and ultra-strength steel, a range of cost-effective Stein horizontal furnaces and rapid cooling solutions for different applications, as well as Aeris®, an after-pot cooling system that improves strip stability.

Stein Digiflex® furnace for annealing and galvanizing: automotive steels

The Stein Digiflex® furnace is at the heart of steel strip processing lines to produce advanced high-strength steel. It provides the best product quality with minimum OPEX and environmental impact.

Stein horizontal furnaces for annealing and galvanizing

The furnace configuration for strip processing lines depends on several criteria: heat treatment, quality requirements and space availability. Fives has developed a range of Stein horizontal furnaces.

FlashCooling technology

Advanced and ultra high-strength steels require more complex heating and cooling cycles for strip processing lines. Fives has designed FlashCooling® technology for vertical furnaces to cover any cooling rate.

Rapid cooling for strip processing lines

Fives' rapid cooling section offers a flexible and compact way to perfectly cool the strip, including high strength steel. The compact design has a number of benefits, including the better cooling rate control and the significant energy savings. 

Aeris, after-pot cooling

For galvanizing processes, the cooling tower design remains a major issue for product quality. Fives has designed Aeris®, an efficient cooling system that improves strip stability by enabling the reduction of the cooling length. 

Stein curing ovens

The scope of supply includes a wide range of Stein curing coating ovens with different types of heating (gas, induction, direct, indirect) and adapted cooling systems (air, water cooler, cooling rolls).

Pre & post treatment ovens

A wide range of pre & post-treatment solutions, including Stein drying ovens are available to achieve final coating: chrome free, zinc phosphate, anti-finger print, resin coat, primer & finish coat, etc.
