Abstract
The invention relates to a method for producing a metal strip (1) by continuous casting. According to said method, a slab (3), preferably a thin slab, is initially cast in a casting machine (2), said slab being deviated from a vertical direction (V) into a horizontal direction (H), and in the direction of transport (F) of the slab (3) arranged behind the casting machine (2), the slab (3) is subjected to a milling operation in the milling machine (4), in which at least one surface of the slab (3), preferably two surfaces which are opposite to each other, are milled. In order to obtain a high economic viability and improved machining parameters when the strips are rolled, the slab (3) is milled as a first mechanical machining step after the slab (3) is deviated in the horizontal direction (H). The slab (3) is cast with a thickness (d) of at least 50 mm and the slab (3) is cast with a mass flow, which is the product of the casting speed and the slab thickness (v x d), of at least 350 m/min x mm. The invention also relates to a device for producing a metal strip by continuous casting.
Claims (5)
1. A method of producing a metal strip (1) using continuous casting, a strand (3), preferably a thin strand, being initially cast in a casting machine (2) and being diverted from vertical downward travel (V) to horizontal travel (H), and, in the travel direction (F) of the strand (3), the strand (3) being subjected, downstream of the casting machine (2), to a milling operation in a milling machine (4) in which at least one surface of the strand (3) is milled off and preferably two opposing surfaces are milled off, characterized in that the strand (3) is milled as a first mechanical machining step after the strand (3) has been diverted to horizontal travel (H), the strand (3) is cast with a thickness (d) of at least 50 mm, the strand (3) is cast with a mass flow, as the product of casting speed and strand thickness (v x d), of at least 350 m/min x mm or of at least 280 m/min x mm when the strand is high-strength material having a carbon content of C > 0.3%, silicon steel, or micro-alloyed steel, milling of the strand (3) takes place immediately after the strand (3) is diverted to horizontal travel (H) or after the strand (3) is diverted to horizontal travel (H) and has passed through a thermal equalization section (5) and/or an oven (13);
the strand (3) is milled in the milling machine (4) such that strand upper face and the strand lower face are milled off at the same location in the travel direction (F), and the amount milled off the strand is apportioned between the upper and lower faces of the strand (3) by vertical adjustment of driving rollers (21) and/or guide plates (22) upstream and downstream of the milling cutter (6) or milling machine (4)
the strand (3) is milled in the milling machine (4) such that strand upper face and the strand lower face are milled off at the same location in the travel direction (F), and the amount milled off the strand is apportioned between the upper and lower faces of the strand (3) by vertical adjustment of driving rollers (21) and/or guide plates (22) upstream and downstream of the milling cutter (6) or milling machine (4)
2. The method in accordance with claim 1, characterized in that upstream or downstream of the milling machine (4) at least one surface parameter of the strand (3) is measured and the machining parameters during milling are set as a function of the measured surface parameter.
3. The method in accordance with claim 2, characterized in that milling depth is a function of the measured surface parameter.
4. The method in accordance with claim 2, characterized in that as a function of the measured surface parameter, at least one milling cutter (6) of the milling machine (4) is bent about a horizontal axis (M) that is perpendicular to its longitudinal axis (7).
5. The method in accordance with any of claims 2 through 4, characterized in that the strand (3) is cleaned prior to the measurement of the surface parameter.
