Definitions

  • the invention relates to a process for the continuous austenitic rolling of a pre-strip produced in a continuous casting process in a continuous casting plant with a casting thickness of less than 300 mm, preferably with a casting thickness of less than 150 mm, by thickness reduction steps in at least one of several successive rolling stands - Rolling mill to a hot strip with a Walzenddicke between 0.5 and 15 mm and subsequent transverse division of the rolled hot strip in waist sizes or bundle lengths before winding in a storage device.
  • the invention relates to a combined casting and rolling plant for the production of austenitic rolled hot strip in a continuous continuous casting and rolling process with a continuous casting for casting steel strands with a casting thickness of less than 300 mm, preferably for casting steel strands with a casting thickness of less as 150 mm, and with at least one rolling mill, which comprises a plurality of successive rolling stands, for producing a austenitic temperature range rolled hot strip with a Walzenddicke between 0.5 and 15 mm and a last mill downstream subdivision and strip storage device.
  • a process according to the invention for the continuous austenitic rolling of a pre-strip produced in a continuous casting process is to be understood as a process in which the pre-strip produced in a continuous casting line without pre-strip cutting section has a casting speed into the first rolling stand or the first rolling line and transport speed into each with a reduction in thickness subsequent rolling mill is introduced to produce hot strip.
  • the combined casting and rolling mill is configured in its structural configuration so that the cast pre-strip enters the first mill stand of the first mill train without a pre-strip parting cut at casting speed.
  • a combined casting and rolling process in which a steel strip cast in a continuous casting plant is rolled in two deformation steps directly from the casting heat and without a separating cut between the casting plant and the downstream rolling devices.
  • a first rolling deformation of the cast steel strand takes place immediately after the solidification in the outlet region of the continuous casting plant with a single roll stand at a strand temperature of about 1100 ° C.
  • the further rolling takes place in a multi-stand rolling train with a rolling speed which depends on the casting speed, which is a maximum of 5 m / min, and the degree of deformation achieved in the first rolling stand.
  • an inductive reheating of the steel strip between the first roll stand and the subsequent rolling train is absolutely necessary. Intermediate heating stages between the individual rolling mills of the rolling train are also provided.
  • a combined casting and rolling process in which a cast steel strand produced in a continuous casting plant is roll-formed without prior transverse division in two successive stages of deformation into a rollable material having cold rolling properties.
  • a first Dikkenredulement the cast steel strand is still within the continuous casting machine at a time in which the steel strand still has a liquid core (liquid core reduction).

Due to different circumstances in the casting process, a steel strip temperature at the end of the continuous casting plant can no longer be ensured due to operational conditions, which no longer guarantees austenitic rolling in the last stand of the rolling train and can not be corrected by the homogenization before the first rolling stand.
  • the object of the present invention is therefore to avoid the disadvantages of the known prior art and a method for the continuous austenitic rolling of a pre-strip produced in a continuous casting process with minimized capital expenditure by specifying the maximum number of scaffolds, intermediate heaters and / or heating powers and in dependence of proposed production and material indicators.
  • These include, for example, the final roll thickness (of the strip to be wound) and the casting thickness and the austenite limit temperature defined by the chemical analysis.
