Problems solved by technology

[0004] The disadvantage of flame cleaning is that the melted material cannot be melted back in without treatment due to its high oxygen content.
[0014] It has been proven that this or the durability of the milling cutters used in milling machines for milling thin sheet surfaces, that is to say the service life of the milling cutters is not always satisfactory

Embodiment Construction

[0050] figure 1 A device for producing metal strip 1 by continuous casting is shown. The metal strip 1 or the corresponding slab 3 is continuously cast in a known manner in a casting machine 2 . The slab 3 is preferably a thin slab. The slab 3 is cleaned in a cleaning device 19 following the casting machine 2 . The surface is then checked by means of a surface measuring device 20 . The slab 3 then enters a furnace 21 so that the slab can be kept at a desired process temperature. Then the furnace is a transfer device ( )twenty two.

[0051] After the furnace 21 or the transfer device 22 the slab 3 enters a milling machine 4 . In this milling machine, approximately spaced apart in the conveying direction F, two milling cutters 6 are provided, with which the bottom surface or the top surface of the slab 3 can be milled. The respective opposing surface of the slab 3 , that is to say the upper or lower side of the slab is supported by support rollers 18 .

[0052] After th...

Abstract

The invention relates to a device for producing a metal strip (1) by continuous casting, using a casting machine (2) in which a slab (3) is cast. At least one milling machine (4) is arranged in the direction of transport (F) of the slab (3) behind the casting machine (2) in which at least one surface of the slab (3), preferably two surfaces which are opposite to each other, can be milled. According to the invention, in order to optimise the service life of the milling cutter of the milling machine, means (5) for cooling the milling cutter (6) are provided on or in the milling machine (4). Theinvention also relates to a method for producing a metal strip.

Description

technical field [0001] The invention relates to a device for producing metal strips by continuous casting, which has a casting machine in which a slab is cast, wherein at least one milling machine is arranged downstream of the casting machine in the conveying direction of the slab, In this milling machine at least one surface, preferably two mutually opposite surfaces, of the slab can be milled. Furthermore, the invention relates to a method for producing a metal strip. Background technique [0002] During the continuous casting of slabs in a continuous casting plant, surface defects such as oscillation marks, mold flux defects or surface cracks arranged longitudinally and transversely can occur, for example. These defects occur in conventional and thin slab casters. Depending on the intended use of the finished metal strip, conventional slabs are therefore partially flame-cleaned. Some slabs are generally flame cleaned according to user requirements. The requirements pl...
