Definitions
- the invention relates to a method for producing a decarburized hot strip, which is produced from a quenching steel containing at least 0.4 wt .-% carbon.
- Hot rolled strips produced from steels of this type have a high hardness and are therefore particularly suitable for the production of articles which are exposed to high localized loads during use. This is the case, for example, in the case of punching blades or comparable cutting tools in which both the cutting edge and the blade body carrying the cutting edge have to absorb high forces during the cutting operation in practical use.
- a hot strip is hot rolled from a slab at a final rolling temperature of 850-950 0 C.
- the resulting hot strip is then coiled at a reel temperature of 600 0 C and then cold rolled to the desired final thickness.
- 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.
- a steel containing 0.04 wt.% C must first be heated to the required decarburization annealing temperature under a substantially dry atmosphere for 8 to 12 hours. Subsequently, water vapor in the ratio 200: 1 is then added to the furnace atmosphere to initiate the decarburization process. Then decarburization annealing is continued for a further 10 hours under the reducing atmosphere so formed until the desired reduction in carbon content is achieved.
- 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.
- a steel strip is first produced in known manner from a quenching steel containing at least 0.4% by weight of carbon.
- This steel strip can be a cold or a hot strip, the procedure according to the invention being particularly suitable for the treatment of hot strip which is to be processed with a specific thickness lying above the thickness of cold strip.
- the steel strip is wound according to the invention to an open coil and heated as an open coil over a sufficiently long period of time to a decarburization annealing temperature.
- a decarburization annealing temperature This may be up to 20 0 C, in particular up to 10 0 C, below the A cl temperature of the respective tempering steel and must not exceed the A c3 temperature of the respective tempering steel.
- the decarburizing annealing of the steel strip in the open coil is then carried out under a decarburizing atmosphere for a decarburization annealing time of at least 90 minutes.
- the decarburizing gas forming the decarburizing atmosphere flows through the gaps existing between the winding layers of the open coil.
- the advantage of the decarburization annealing according to the invention in wound to an open coil steel strip is that can be achieved in this way time-saving uniform temperature distribution over the length and width of each processed steel strip.
- the annealing conditions are chosen according to the invention so that there is a uniformly distributed structure state over the entire strip. So is by the invention given range of the annealing temperature ensures that in each processed band still sufficient amounts of ferrite are present in order to allow rapid diffusion of the carbon. This is up to a hundredfold faster in ferrite than in austenite.
- the decarburization annealing temperature according to the invention is preferably set in a range which is lower by 10 to 20 0 C than the A Ci temperature. This setting of the decarburization annealing temperature ensures that the tempering steel of the respective processed steel strip has a ferritic structure, so that an optimum diffusion rate of the carbon is achieved.
- the open coil is accelerated cooled to prevent any undesirable and, in terms of its extent, insecure subsequent diffusion of carbon into the previously deliberately decarburized surface layer as a result of the coil's inherent heat.
- the accelerated cooling should take place as soon as possible, as soon as possible after the end of the decarburization annealing time and at a cooling rate of at least 1 ° C / min.
- steel sheet is one starting from the respective Decarburized surface layer measured measured surface of the steel strip whose depth is in each case smaller than a quarter of the thickness of the steel strip, so that only near-surface areas are included in the decarburization according to the invention.
- the parameters of the method according to the invention are preferably chosen so that decarburization depths of a maximum of 120 ⁇ m, in particular 30-120 ⁇ m, are achieved.
- the steel strip obtained by the procedure according to the invention is consequently characterized in that it has a high bend formability in the region of a near-surface layer as a result of the decarburization treatment.
- the strip treated according to the invention has a high core hardness.
- heat-treated steel strip as a result of WeichglühClouds has a relation to the initial state lowered strength, which has a favorable effect on the possibilities of further processing.
- the inventive method can be carried out particularly cost effective and efficient.
- steel sheet produced according to the invention can be used particularly well, for example, for the production of punching knives or similar objects which, if necessary, must be bent sharply in order to obtain their intended shape.
- the production of a semifinished product made of sheet steel according to the invention may include separation operations, such as stamping or cutting, as well as forming operations, such as deep drawing or bending. If necessary, the semifinished products thus produced can also undergo a final tempering treatment.
- the decarburization time selected in each case when carrying out the process according to the invention depends on the respectively required decarburization depth. It is typically at least 90 minutes. According to experience, the decarburization depth of at least 30 ⁇ m can be achieved in this time, for example in the case of tempered steels having a C content of 0.55% by weight, under the operating parameters prescribed by the invention.
- the duration over which the decarburization treatment according to the invention has to be carried out in order to achieve a specific decarburization depth can be determined for a given decarburization temperature, given decarburization depth and given dew point of the decarburisation atmosphere on the basis of the carbon content and the coil weight of the steel strip to be treated. Should the decarburization depth be a maximum of 120 ⁇ m can be limited, it can be seen from experience, the decarburization annealing limited to a maximum of 120 minutes.
- a gas mixture of nitrogen, hydrogen and steam is also used in the implementation of the decarburization according to the invention as decarburization gas.
- decarburization gas typically, such a decarburizing atmosphere at a between 20 - 28 0 C, in particular 20
- the heating to the decarburization temperature also takes place in the process according to the invention initially under a protective gas atmosphere.
- the decarburization temperature is reached, the steel strip in the open coil is exposed to the decarburizing atmosphere.
- the inert gas atmosphere maintained during the heating can be 85-97% by volume of nitrogen and 3
- the amount of water required for the decarburization reaction in the furnace can be regulated as a function of the dew point.
- the dew point of the decarburization atmosphere over the entire Decarburization annealing time are detected.
- the water vapor content of the decarburizing atmosphere is then adjusted so that the dew point of the atmosphere is maintained in the range of 20-26%.
- the steel strip In order to remove possibly existing oxide layers and lubricant residues on the processed steel strip, the steel strip should be pickled before winding to the open coil.
- the method according to the invention can be carried out in a particularly simple manner when the heating and decarburization annealing of the open coil takes place in a hood annealing furnace.
- a tempering steel suitable for the production of steel sheets processed according to the invention typically has the following composition (in% by weight):
- 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 slab has been hot rolled in a conventional manner to a steel strip.
- the final temperature of the hot rolling was in the range of 850-950 0 C, wherein the specifically selected here Kaltwal zendtemperatur 900 0 C.
- the temper rolled steel strip was then wound in a conventional manner to an open coil.
- the winding layers of the steel strip have been held by inserting a wire or other suitable means at a distance, that between each two adjacent layers, a gas-permeable space is formed.
