Abstract

In a process for producing a hot-rolled product by continuously casting a strand, separating a strand piece from the strand, thermally influencing the strand piece by temperature equalization and/or strand piece heating and hot-rolling the strand piece, continuous casting takes place at two or several continuous casters. The strand pieces are rolled in a rolling mill associated with these continuous casters, to which the strand pieces are conducted by diverting the strand pieces into the line of the rolling mill from at least one of the continuous casters whose line does not register with the line of the rolling mill. In order to reach a higher plant availability, thermal influence of the strand pieces to be diverted is effected during the diversion of the strand pieces after their emergence from the continuous caster line and prior to their introduction into the rolling mill line while completely clearing the continuous caster lines and the rolling mill line.

Claims3

Dependent claims

A process for producing a hot-rolled product, comprising:

continuously casing a strand;
separating a strand piece from the strand;
thermally influencing the strand piece by temperature equalization and/or strand piece heating;
and
hot-rolling the strand piece;
wherein the continuous casting takes place in at least two continuous casters, and
the strand piece is rolled in a rolling mill associated with the continuous casters and to which the strand piece is conducted by diverting the strand piece into a line of the rolling mill from at least one of the continuous casters having a line that does not register with the line of the rolling mill, and
wherein thermal influence is effected during the diversion of the strand piece, and wherein thermal influence is effected in a furnace provided between the lines of the continuous casters and the line of the rolling mill and wherein from a line of the continuous casters a strand piece is disposed, while being brought in alignment with the furnace, by means of a pivotable or laterally displaceable guide section of said line of the continuous casters and from the furnace is displaced, while being brought in alignment with the line of the rolling mill, by means of a pivotable or laterally displaceable guide section of the line of the rolling mill, said guide section of the line of the rolling mill being provided at an opposed end of the furnace.
