Abstract

The rods, up to approximately 150 mm in diameter, are used especially for mechanical construction; this treatment, which is carried out at rolling heat, comprises the following three successive stages: a) a severe forced cooling on the run by a sheet of water 2, to lower the average temperature of the section to approximately 600-550 DEG C over a minimum length, for example less than 30 m, b) natural air cooling on a cooling bed 29 for a certain thermal homogenisation of the section and autotempering of the surface martensite, c) a second forced cooling on the cooling bed either by spraying water at 28a or by immersion, at least to an average temperature of the order of 300 DEG C, it being possible for the final cooling to take place in air at 27. This treatment may be supplemented by conventional tempering. <IMAGE>
