The alloying metals form cations within the mill scale at about the alloying proportions* due to the almost instantaneous oxidation of freshly exposed metal at high temperature. Fe3O4 contains both Fe+2 and Fe+3, and is sometimes written FeO·Fe2O3. Ni+2 substitutes for Fe+2, Al+3 and Cr+3 substitute for Fe+3. Thus, (Fe,Ni)O·(Fe,Al,Cr)2O3.

Roll selection for Cold Rolling mills. 1. Tandem Mill Rolls. Pic.1 Five Stands Tandem Mill Rolling Line
cold milling work rolls for 2-hi, 4-hi and skin pass mills The experience acquired in the field of the heat treatments, together with a wide knowledge of the characteristics of the steels and machining cycles allow B.S.A. to produce forged rolls of low, medium and high alloyed tool steels.
There is also another finishing between hot rolling process and cold rolling process, Pickled and Oiled. By being pickled in acid and oiled, the mill scale on the hot rolled steel can be removed and protect it from rusting. Picking and oiling cost is somewhere in between regular hot rolling and cold rolling.
It's the part of our Flex Mill™ where beauty meets brawn and exceptional surface finish meets high formability. Our range of cold rolled steel products is one of the most extensive in the industry, crafted by steel technicians who understand the science – and the art – of steelmaking.

Cold rolled coil, strip and sheet are produced in all stainless steel types: austenitic, ferritic, duplex and martensitic. A wide selection of standard and special surface finishes provide a unique level of customization. Outokumpu offering includes semi-cold rolled surface RAP®2E: it is cold rolled, heat treated, mechanically descaled and ...
1) The temperature inside mill housing. Rolling generates heat. The oil flow removes the heat, and a balanced rolling conditions, particularly on the speed and the reduction size. The work rolls heat up quickly — faster than the intermediate rolls and back-up rolls. In the short time period between two passes, cooling is negligible.
The following are some of the key differences in hot rolled vs cold rolled steel: Hot rolled steel is rolled or shaped at a high temperature while cold rolled steel is rolled at room temperature. Cold rolled has a smooth and shiny finish while hot rolled has a grey and scaly finish.
The rolling of steel is mainly hot rolling, and cold rolling is usually used only for the production of steel with precise size such as small sized section steel and thin plates. Wire Rod. The diameter of 5.5-40 mm, coil, all is hot rolled material. After cold drawing, it is cold drawing material.

Rolls (cold and hot mill rolls) In its program, Production and Engineering Company ENCE (ЭНЦЕ ГмбХ) highlights the most significant metallurgical equipment; this equipment complies with the highest international quality standards and may be offered to customers at competitive prices.
Cold drawing increases tensile and yield strength but decreases ductility. Cold drawing also increases torsional strength, surface hardness and wear resistance. Due to size limitations of the cold drawing process, large diameter bars are generally turned and polished, the hot roll rounds usually machine turned, rather than drawn, then abrasively polished.
Differences between Hot Rolled Coil and Cold Rolled Coil Leave a reply Before souring steel materials for a project, you should to know the differences between the different types of steel, How it is used and what are the advantages and disadvantages.
From hot to cold - covering a wide variety of needs . Union Electric Åkers supplies rolls to some of the world's leading aluminum mills. We were the first roll manufacturer to introduce the 5% Cr and 10% Cr semi HSS grade with considerably improved performance for the hot mill process.
Dec 08, 2013 · roll life, rolling, rolling mill, rolls, Rolling Mills Rolls. Rolling had assumed importance in the industrialized world during the nineteenth century. Profiles and flats are hot rolled while some flat products are also cold rolled. Rolls are tools in the rolling mill. The weight of the rolls can vary from a few kilograms to as high as 250 tons.
