Steel Belt

Steels belts are used in many industries such as food, chemical, wood processing and transportation.

They are generally made from carbon Steel or stainless steel. Stainless steel belts are corrosion resistant and provide excellent surface quality. Stainless steel belts are used primarily in the chemical, food, rubber, plastic, wood, and laminate industries. Carbon steel belts are energy efficient and ideal for applications necessitating radiant heating of products or in high temperature applications that might exceed the annealing temperatures of stainless steel belts also carbon steel belts can more evenly distributed heat since most stainless steel alloys are comparatively poor heat conductors. Carbon steel belts are used primarily in food processing, transport and bake ovens.

Normally, ground stainless steel belts delivered with surface roughness from Ra 0,4 µm down to 0,1 µm and with well-rounded edges. Ground steel belts are leveled and straightened to obtain optimal flatness and straightness and can be supplied in open lengths, with the ends prepared for welding on site, or in endless condition with a welded joint.

Perforated steel belts enabling the drying media, for example hot air, to be transferred 'through' the steel belt, so that the air is in contact with all parts of the product on the belt. Normally, all manufacturer are offers perforated belts with five standard perforation patterns which cover ring most requirements. A broad range of other patterns, with a minimum hole diameter of 0.8 mm (0.03 in.) and different spacing, can be provided to suit specific applications.

Super-mirror-polished stainless steel belts for the production of different types of thin film and ceramic sheets. The belts are available in thickness from 0.60 to 2.00 mm (0.02362 to 0.0787 in.) with thickness variation less than or equal to 80 µm. Polished steel belts are delivered endless or as open-length belts.

Seamless steel belts suitable for the production of high-quality plastic foils and films such as optical film and packaging film. Its normally with thickness ranging from 0.03 to 0.60 mm (0.012 to 0.23 inch). Seamless steel belts are suitable for machines with narrow drum diameters using wide belts.

Solid stainless steel belts are, as standard, delivered in cold-rolled condition with a mill finish of Ra < 0,4 µm and have well-rounded edges. Carbon steel belts are, as standard, delivered in a hardened and tempered condition with a mill finish of Ra < 0,4 µm and have well-rounded edges. Solid steel belts are leveled and straightened to obtain optimal flatness and straightness and it will be supplied in open lengths, with the ends prepared for welding on site, or in endless condition with a welded joint.

In both cases the material is a special grade for carbon or stainless steel specifically designed for use as a steel belt, with the material specially alloyed or treated to have improved properties such ductility, strength, thermal conductivity etc. depending on the application.
