METALLURGICAL ROLLS, DIE BLOCKS, FORGED PRODUCTS

One of the main domains of the operations of the Rolls-Rolls, Inc. Company is the production and delivery of tools for plastic working, mainly rolls and drop forging dies for hammers and presses, to steelworks and metallurgical processing plants (forges, mills). These are tools of a high crack resistance, abrasion resistance and thermal tempering resistance.

They are made of steels, which chemical compositions and heat treatment technologies are strongly guarded secrets of the Company. Precisely collected data bases concerning the influence of individual alloy elements, combined with long term experience, allow producing of tools of unusual, and sometimes even of unimaginably excellent, properties. These can be flat and grooved rolls, for cold and hot works, die blocks for presses and hammers as well as different tools and forged products from which a high crack, abrasion and thermal tempering resistance - at maintaining their high hardness - is required.

Our products: metallurgical rolls, drop forging dies and other forgings are successfully operating in several steelworks, forges and other manufacturing plants. Working and backing-up rolls for sheet rolling and mandrels for pilgrim rolling of tubes are used in Batory Steelworks. Mandrels for pilgrim rolling of tubes are used in Częstochowa Steelworks. Shape rolls are operating in Zawiercie Steelworks. ArcelorMittal Poland uses shape and flat rolls (for universal stands). We made main shafts (28 tonnes) for wind power plants in Ostrowiec Steelworks, and flat rolls in Cold Mill of Termetal Company in Piła, in forges: Tasta Armatura in Stalowa Wola and Aesculap Chifa in Nowy Tomyśl we made drop forging dies.

PUBLISHING HOUSE

The Rolls-Rolls, Inc. Company is also the publisher of books related in their subjects to metal materials and metallurgical products. In 2016 the Company published the three-volume work authored by Professor, PhD. DSc. Eng. Jerzy Pacyna, entitled: ”Steels for metallurgical products”. The first volume concerns the terminology applied in the description and grades of steels, the second volume concerns steels for semi-products and flat products, while the third volume concerns steels for long products.

The chemical compositions and applied heat treatments are given for all steels and each group is provided with the authors comments and remarks. All steels are described in accordance with the European standards EN. We would like to encourage the interested persons to acquaint themselves with the table of contents, list of quoted standards and information concerning the author. We also make available the order forms.
Publishing the book entitled; “Tool steels” is expected in the nearest future. This book will concern steels for rolls, for drop forging dies of presses and hammers as well as steels for untypical tools such as mandrels for pilgrim rolling of tubes or tools for forging crank shafts, by means of prof. Rut’s method.
