US 5,305,515 A · Method and arrangement for rolling hot wide strips from continuously cast thin slabs

Abstract

A method and an arrangement for rolling hot wide strips from continuously cast thin slabs in successive steps of operation of a rolling line which includes a continuous finishing train. One or more casting lines and individual thin slabs are severed from the cast strand. The thin slabs are homogenized and adjusted to rolling temperature in an equalizing furnace and the thin slabs are transferred from the equalizing furnace to the rolling line. Roller-type turning furnaces provided in each of the casting lines and in the rolling line are use by turning the roller-type turning furnaces toward each other into positions which are inclined relative to the casting and rolling lines in the manner of switches for alternatingly conveying thin slabs from one of the casting lines through the roller-type turning furnaces into the rolling line.

A method of rolling hot-rolled wide strips from continuously cast thin slabs in successive steps of operation of a rolling line which includes a continuous finishing train, said method comprising the steps of:

producing continuously cast strands in a plurality of casting lines;
severing individual thin slabs from the cast strands;
homogenizing and adjusting to rolling temperature the thin slabs in equalizing furnaces provided in the plurality of casting lines;
providing a roller-type turning furnace in each of the casting lines after the equalizing furnace and the roller line for alternately conveying thin slabs from one of the casting lines into the rolling line;
and
turning the roller-type turning furnaces toward each other into positions which are inclined relative to the casting and rolling lines thereby to form a switch between the casting lines and the rolling line.

A arrangement for rolling hot wide strips from continuously cast thin slabs in a rolling line which includes a continuous finishing train, said arrangement comprising:

a plurality of casting lines for producing cast strands;
means for severing individual thin slabs from the produced cast strands;
an equalizing furnace in each of the plurality of casting line;
and
means for alternatively conveying thin slabs from a casting line to the rolling line, wherein the conveying means comprises a roller-type turning furnace in each of the plurality of casting lines and in the rolling line, the roller-type turning furnace of the casting lines and the roller-type turning furnace of the rolling line being longitudinally offset relative to each other in conveying direction of the thin slabs approximately by a length of a roller-type turning furnace;
and wherein each of the roller-type turning furnaces has a turning point, the turning points of the turning furnaces of the casting lines being arranged at a rearward end of the turning furnaces in a conveying direction, and the turning point of the turning furnace of the rolling line being arranged at a forward end of the turning furnace in the conveying direction, so that the turning furnace in the rolling line and the turning furnace in a respective one of the casting lines form a straight-line transition from the respective casting line to the rolling line, when the furnaces are turned into aligned positions in the manner of a switch.
