in the Swíng of
Sheet Metal Program
The activities of rolling mill branch are targed mainly to sheet metal processing area. In the framework of sheet metal program the most important projects were delivery of combined cut to length and slitting line for Hutní závody Břidličná, , cut-to-length line for US STEEL Košice and modernisation of the cuttíng line for Nová huf Ostrava. The cut-to-length line in Košice is processing the cold rolled tin plated sheet metal strip into plates stacked in stacks of specified number of pieces or specífied weight, classi- fíed as per the quality into the individual stackíng positions. The line is provided with new type of ZDAZ  flyíng drum shears. These unique shears are used also in lines supplied by American company LITTELL located in Chicago. The initial materíal is 15 ton coil of cold rolled sheet metal strip. The strip ís one or both sides tin plated and oiled with electrostatic method. The unique tech- nical parameters of the line are proved by accuracy achieved during plates cutting that is mm at cuts per second. The line produces stacks of sheet metal plates of required size, placed on pallets and classified as peг the quality in the individual stacking positions. The capacity of the line is depen- dent on working speed, thickness and width of cut sheet metal strip. The productivity is also influenced by length and number of plates in stack as well as the size of processed coil.

Dividing of the Coiled Materíal

The increasing demand on the packing sheet metal, hígher demand on

quality of the divided material and its dímensional accuracy are the reasons 7
why our designers finalïsed development of the edge slitters. This equipment

was successfully commissioned during the zínc plating line modernisation.
The characteristic features of this equipment are a high qualíty of slít edges ó
and the accuracy of setting the slit width of mm. The capacity tests were Э o\y
alśo completed at the same customer on the cut-to-length line for the cold
1 -1dN
rolled tin plated sheet metal strip. This line cutting the coils to sheet metal
plates of a required size is equipped with the flying drum shear of the Žd as
design. The shear is the crucial equipment of each líne and it ís provided for
heavy duty service.
One of the most important references of ZDAZ, at this customer is the
delivery of the cut-to-length line No. 15 for packıng sheet metal plate. This
line is equipped wïth the most modern shear for cutting the sheet metal
plates to length with the dimensional accuracy of mm at the operating
speed of m/s. The equipment was put in operation in 2000.
The successful project carries out with the delivery of the cut-to-length line
No. 16 and the reconstruction of the slitting line aimed to unificatíon of the
entry coil sizes as per the world-wide and maínly the American markets,
where the majority of production will be exported to.

Inspection Lines
ZDAZ, in co-operation with the Czech company DEL, developed and
successfully handed over the inspection lines for grinding, NDT testing and
marking of the round bars to the Swedish customer sANDV1K. The important
features of these lines are high flexibility, large assortment of products and
mainly the reduced noise during material handling that ís below the límits
rated in the international standards.
