Definitions
- the invention relates to a method for producing a workpiece from a strip of hot-rolled steel sheet.
- the object of the invention is to propose sheet steel rolled from 0.2 mm to about 20 mm thick, coated after hot rolling, and to be shaped, either hot or cold followed a heat treatment, the temperature rise to be ensured without decarburization of the sheet steel, without oxidation of the surface of said sheet, before, during and after hot forming and or heat treatment.
- the method according to the invention consists in coating a hot rolled steel, for heat treatment and hot forming, with a metal or a metal alloy such as aluminum or an aluminum alloy composed for example of aluminum and of silicon.
- the metal or metal alloy coating is selected to have corrosion protection and to withstand a high temperature.
- the coating forms an alloy layer having a high resistance to corrosion, abrasion, wear and fatigue.
- the coating does not does not modify the formability properties of steel and thus allows a wide variety of cold and hot forming.
- the strip After hot rolling the strip can be pickled and cold rolled before being coated.
- the sheet is subjected to a temperature rise preferably between 750 ° C and 1200 ° C in an oven with an atmosphere no longer requiring control because of the barrier to oxidation formed by the coating.
- a temperature rise preferably between 750 ° C and 1200 ° C in an oven with an atmosphere no longer requiring control because of the barrier to oxidation formed by the coating.
- the aluminum-based coating is transformed into an alloyed surface layer having different phases depending on the temperature treatment and having a high hardness of more than 600 HV 100g.
- the sheets delivered coated have a significant resistance to corrosion during temperature rises, shaping, heat treatments, and during the use of finished formed parts.
- the presence of the coating during heat treatments or hot forming avoids in addition to corrosion, the decarburization of the base steel. This has an undeniable advantage in the case of hot forming in a stamping press.
- the formed intermetallic alloy avoids the formation of calamine, the wear of the tools by calamine, and thereby allows an extension of the average life of said tools. It has been noticed that the hot formed intermetallic alloy has a high temperature lubricant function.
- the effect of protection against decarburization of the intermetallic alloy allows the use of high temperature furnace exceeding 900 ° C having an uncontrolled atmosphere, and this, even for heating times of several hours.
- the coating Due to the characteristics of the coating after temperature rise, the resulting pieces have increased resistance to fatigue, wear, abrasion and corrosion. In addition, the coating is weldable before and after temperature rise.
- the steel of the sheet provides, by quenching effect on cooling, high mechanical characteristics of the part obtained after shaping, the coating converted into a hot intermetallic alloy, for its part, because of its lubricant qualities and resistance to friction, an improvement in shaping, in the field of hot stamping.
