TH47206A - Heat extrusion of long, thin strips - Google Patents

Abstract

DC60 (10/01/44) thin long steel strip (11) is thrust through the throttle pinion roller stand (12) containing the throttle pinch roller (13) to the hot extruder (16) containing Working roller (17) and support roller (18) before reaching the rolling machine (16), the long bar passes over Support roller (15), anti-corrosive pilot roller (21), positioned Immediately before the press (16), it is mounted on a pair of levers (22) to allow lifting. From non-operating position below to lift longer bar from a straight line to pass It is wrapped around the anti-roll roller and wrapped around the upper working roller (17) before the clamping hole (26) through a wrap angle of at least 10 degrees. Wrap a long strip around the upper work roller (17). That roller will support the long strip and resist. Withstanding long strip deflection and resistance to curling defects, the thin long steel strip (11) is passed through the throttle pinion roller track (12) containing the throttle clamping roller (13). Also a hot extruder (16) containing Working roller (17) and support roller (18) before reaching the extruder (16), the long bar passes above Support roller (15) The pilot roller on the wavy side (21) is positioned. Immediately before the press (16), it is mounted on a pair of levers (22) to allow lifting. From non-operating position below to lift longer bar from straight line to pass It is wrapped around the anti-roll roller and wrapped around the upper working roller (17) before the clamping hole (26) through a wrap angle of at least 10 degrees. Wrap a long strip around the upper work roller (17). That roller will support the long strip and resist. Excellent resistance to long strip deflection and resistance to curl defects

Claims (9)

1. A method for producing long strips of steel in which the long strips (11) are produced by Continuous casting In a twin-roller longitudinal casting machine to a thickness of 5 mm or less and the thickness is reduced by a reduction in a row heat press (16) while being produced. By casting machine By feeding the casting bar (11) through the clamping hole between the pair of working rollers (17) of the extruder (16) and the compression feeding between the working rollers to the long bar. With features that In order to reduce the defects of the long strip that occur. During hot rolling of the strip due to sliding towards the back of the center of the long strip (11) in relation to the edge resulting from variation in the reduction of the length of the strip along the width of the The long strip that will exit the casting machine is passed before the work roller (17) is rubbed around the pilot roller (21), causing the long strip to be wrapped on one of the work rollers (17) before Reach the entrance to its clamping hole (25) between the working rollers (17). 2. The method described in claim 1 is unique in that a long strip (11) is wrapped around one such work roller (17). Through an angle of encapsulation having a value of at least 10 degrees 3. The method as stated in claim 2, which is characterized by that The angle of encapsulation is in the range of 20 degrees to 45 degrees. 4. The procedure set forth in any Clause 1 to 3, which has the specific characteristics that Work rollers (17) are positioned on top of the other. 5. The method as stated in claim 4, which is characterized by that The pilot roller (21) is positioned so that the long strip (11) is directed upwards from the flat trajectory to the clamping hole and downward around the working roller (17) above, before the clamping hole. 6. Equipment for the production of longitudinal steel strips consisting of Long bar casting machine With rollers that can work to cast long continuous steel strips to a thickness of 5 mm or less. And the heat press (16) was installed in a row with the long strip casting machine in order to do the job in reducing the thickness of the strip. By heating the long strip As it was produced The die casting machine (16) consists of a pair of working rollers (17) designated as a clamping hole (26) in between. To accommodate the long bar (11) and the mechanism that will feed the force. Compressed between working rollers It is characterized by that the pilot roller (21) guides the long bar (16) to the pinch (26) between the working rollers (17) in such a way that the long bar is wrapped on the roller. Work one (17) before reaching the entrance to its clamping hole (26). 7. The device, as specified in claim 6, in which the pilot roller (21) can be aligned, guide the long strip (11) so that the long strip is wrapped onto one of the working roller (17) as follows. Said through an encapsulation angle that is at least 10 degrees. 8. Equipment, as stated in claim 7, that the pilot roller (21) can be aligned. The long strip (11) is piloted, where the long strip is wrapped on one such work roller (17) through the wrap angle in the range of 20 ° to 45 °. 9. Equipment as stated in any of the 6 Claims. Where the working rollers (17) are placed on top of the other. And the pilot roller (21) will be moved from the lowered position. Where the long bar can pass over it in a horizontal trajectory to the clamping channel (26) between the working rollers. And higher operating positions Which it raises a long strip above the horizontal trajectory To make a bar The length is wrapped onto the upper work roller (17) before the clamping tube (26).
