Definitions
- the cold strip is wound according to the known method into an "open coil” and decarburizing annealed as an open coil.
- an open-coil is so loosely wound that its individual winding layers are separated by open spaces.
- the reaction gas can flow through the intermediate spaces between the individual layers of the coil, so that with optimized gas flow guidance, each surface of the coil is swept in the same way by the gas.
- the invention was based on the object to provide a method that allows the production of steel strip, in which high hardness on the one hand and good formability on the other hand are optimally combined with each other.
- the inventive method can be carried out particularly cost effective and efficient.
- One consisting of an addition of iron and unavoidable impurities (in% by weight) 0.5% C, 0.2% Si, 0.75% Mn, ⁇ 0.12% P, ⁇ 0.003% S, 0.02% Al and 0.1% Cr containing tempering steel has been cast in conventional continuous casting to a starting material, such as a slab or thin slab.
- the open coil was kept under this atmosphere for a decarburization annealing time of 90 minutes.
- the dew point of the decarburization atmosphere prevailing in the hood furnace has been recorded continuously and adjusted to a desired value.
- the open coil has been cooled in the hood furnace under a protective gas atmosphere at a cooling rate of 1 ° C / min.
