Thanks to years of experience in engineering and manufacturing Danieli has developed its own knife line for flat and long products. These knives contain all the Danieli design and process know-how and are manufactured with the newest technological solutions. Customized solutions are available according to product mix and the strictest customer requirements.

Materials The shear blade is the only component that actually comes into contact with the processed material. It has to be tough enough and must have very good wear resistance in order to perform high-quality cutting and minimize production stops. Danieli's target is to supply the optimal technical and economical solution for the customer's specific shearing application. For this purpose Danieli has developed three different series of materials: DanCut 300 series for cold cutting DanCut 500 series for hot cutting DanCut 700 series for cutting in extreme conditions. Each material in these categories will be specifically chosen by Danieli engineers according to the customer's product mix and shearing application.

Hot strip mill shear blades

Plate mill shear blades

Cold rolling and processing shear blades

Rotary side trimming shear blades

Series of hot cutting blades for standard and high-speed drum shears in the process section, and for pendulum shears after the slab caster. Blades are especially designed to improve cutting quality and are made of special alloy steel grades to withstand heavy cutting conditions (up to 1150 °C).

Group of blades used for cold cutting of thick material up to 50 mm, for dividing shears, side trimmers, scrap choppers and slitting shears. Made of highalloy steel grades in lengths up to 6000 mm. Special alloy steel grade blades are also applied in hot cutting before the cooling beds on drum and guillotine type shears.

Family of cold cutting blades for thin material usually installed on single cut or drum shears, used in Cold Reversing Mills, Temper Mills, Skin-Pass Mills, Pickling Lines, Galvanizing Lines, Annealing Lines etc. Blades are made of high-alloy steel grades customized for each application in order to perform high-precision cuts.

Group of cold cutting disc blades used for strip and plate (up to 30 mm) side trimming with high cut edge quality. These knives are made of high-alloy steel grades in diameters up to 1600 mm.

Long product cut-to-length shear blades

Long product flying shear blades

Family of cold cutting blades with straight or especially shaped cutting edge, able to simultaneously cut to length multiple profiles. Those blades are made in highalloy steel grades characterized by a high toughness, necessary for this kind of application.

Family of hot and cold (QTB) cutting blades with straight or especially shaped cutting edge, used for head and tail cutting, cut to length and emergency cropping. Blades are made in special highalloy steel grades with the best ratio between toughness and wear resistance.

Danieli design and manufacturing Danieli knives are produced with the most modern and high-performance equipment such as CNC milling machines with automatic, indexable highspeed milling heads; horizontal CNC grinding/ profiling machines with automatic grinding cycles for flat and profiled surfaces; and surface grinding machines for segment and peripheral grinding with 11-axes CNC control. Steel grades of knives and all heat treatments are tested and certified according to standard ISO 9001:2000 in order to supply top performance products. The lines of Danieli Knives provide the customer with a range of products that optimize the shearing process in terms of QLC (cutting Quality, knife Lifetime to reduce operating Costs).
