Annealing & galvanizing: other steel applications

Printable Version

Fives developed a range of NeoKoil® strip processing lines, such as continuous annealing lines (CAL), continuous galvanizing lines (CGL) and continuous galvanizing & painting lines (CGPL) and coil coating lines (CCL) dedicated to the production of any metal coated carbon steel products for construction, home appliances, white goods and automotive grades. Such processing lines are cost effective and versatile. The range of custom engineered strip processing lines include: 

  • CAL, CGL and CAGL to produce high-strength steels (HSS), including AHSS and UHSS for the automotive industry. More information
  • CGL with horizontal furnaces to produce steel grades from building to automotive applications quality
  • CGPL and CCL dedicated to production of white products and organic coated products. More information

Fives has engineered and supplied more than 80 CGLs with vertical and horizontal furnaces producing steel grades from building to automotive quality, from mini-lines (10 mpm) to high-speed lines (180 mpm), as well as more than 55 CALs  for silicon & carbon steel, and over 45 coil coating lines worldwide.

Entry coil handling section

Entry coil handling section

The entry coil handling section is engineered to handle the coil very carefully, ensuring minimal waste and optimal product quality. It includes entry coil skid and car, pay off reel, threading pinch roll and flattener, shearing section (entry shear and scrap evacuation system) and coil joining section (welder and notcher).

Degreasing system

Degreasing system

Fives' degreasing system utilizes a combination of hydro, chemical and mechanical processes. The hydro system uses hot water as the degreasing agent. The chemical systems include a multi-stage degreasing section where water with a degreasing agent is sprayed onto the strip at high temperature. This is followed by mechanical brushing of the strip surface to displace fines and stubborn oil from the strip.

Thermal part

Stein horizontal furnace

Stein horizontal furnaces for strip processing lines cover a full range of steel grade applications, such as building, white goods, non-exposed automotive parts, full hard, hot rolled products, etc. The furnaces feature low operation costs, shorter shutdowns during maintenance and easier operation.  Fives has also designed Stein curing ovens to process high quality strip coating for different applications.

Rapid cooling

Rapid cooling

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

Fives has recently developed rapid jet cooling, which provides a high cooling rate of up to 75˚C/sec for processing high strength steel.

After-pot cooling and minispangle

After-pot cooling

Aeris®, after-pot cooling technology, is an efficient and flexible cooling system that improves strip stability by enabling the reduction of the cooling length. Fives has also developed the Stein minispangle system, aiming to minimize ‘spangles’ in galvanized strips in order to improve the surface quality for coating.

Skin-pass and strip leveler

DMS skin-pass and strip leveler

DMS skin-pass mills coupled with DMS strip levelers are suitable for a wide variety of annealed and galvanized steel products from very low to very high strengths. They achieve the proper elongation and improve strip flatness in continuous strip processing lines.
