Cutting of cold-rolled coils at SSC Hradec Králové

Steel Service Centre (SSC) in Hradec Králové opened at the end of 2002 so that Ferona could offer customers cutting of steel rolls as per their requirements. The Steel Service Centre has equipment for both longitudinal and lateral cutting of steel rolls. The SSC also has a test lab.

The service centre's products are sold by employees of Ferona's sales departments.

The Steel Service Centre has a quality management system per EN ISO 9001:2015 and IATF 16949:2016. 9001 certificate available for download. 16949 certificate available for download. 16949 certificate appendix available for download.

The line's production rate is up to 200 m/min. The longitudinal cutting line can produce up to 4 orders at once. The orders are then sorted on the packaging line, individual rolls (strips) are bound and tied together on a pallet or frame. Rolls are protected from the elements as per the customer's specifications (stretch film, anti-corrosion paper).

Cut sheet length tolerances depend on material thickness.

Note: Dimensions not specified in the table are recalculated across sheet size.

 

Standard tolerances for sheet flatness

Grade of steel	DC01 - DC06, mat. with upper yield point < 260 MPa			DX51D and mat. with higher yield point
Nominal width [mm]	Nominal thickness [mm]
	< 0.7	0.7 ≤ t < 1.2	t ≥ 1.2	< 0.7	0.7 ≤ t < 1.2	t ≥ 1.2
	Tolerances [mm]
w < 1200	5	5	5	8	6	5
1200 ≤ w < 1500	6	5	5	9	8	6
w ≥ 1500	8	7	6	12	10	9

For wavelength size up to 200 mm, flatness deviation must not exceed 2 mm.

The line's production rate is up to 90 m/min. The cut-to-length line produces bundles of sheet metal. The bundles are then wrapped in anti-corrosion paper and banded together on the packaging line. Edges are protected with corner protectors.

Hydraulic cutting table

To increase the scope of available services, a hydraulic machine for cutting sheet metal from flat sheets was added to the SSC. The range of thicknesses that can be cut are 0.4 to 6 mm, and up to 3080 in length. The maximum strength of materials being cut depends on their thickness. For thicknesses 0.4-4 mm, the maximum strength is 750 MPa, and for thicknesses 4-6 mm the maximum strength is 450 MPa. Width tolerance is +0.5;-0.5 mm.

Ordering sheet metal cutting at the SSC

Send a request for quote or order to any Ferona branch (via post, fax, in person, phone, or email – see contacts).

If we will be cutting your own material, the request/order has to clearly specify this.

|The business unit will pass your request/order on to the relevant salesperson or clerk, who will then:

• add/clarify your requirements (dimensions including tolerances, quality, and surface finish, total quantity, weight and packaging method, due date, and delivery method;
• put together a quote;
• issue a purchase agreement (if all aspects of the agreement have been clarified).

If we will be cutting the customer's material, when and how the material will be shipped to Ferona's SSC warehouse in Hradec Králové must be clarified.
