Abstract

The invention provides an uncoiling tool of a hot coil box. The uncoiling tool of the hot coil box comprises a tool rest and a tool body. The tool body comprises an uncoiling tool part and two uncoiling rollers which are respectively erected on the two sides of the uncoiling tool part. The two uncoiling rollers are parallel to the uncoiling tool part. A blade part of the uncoiling tool part protrudes out of the uncoiling rollers in the radial direction of the uncoiling rollers. The uncoiling tool of the hot coil box is characterized in that the two ends of the blade part of the uncoiling toolpart separately extend towards the uncoiling rollers to form extension parts which cover local parts of the uncoiling rollers. The uncoiling tool of the hot coil box has the advantages of being wide in application range, good in uncoiling effect, and convenient to maintain.

Description

technical field [0001] The invention belongs to the field of hot coil box uncoiling machinery, and in particular relates to a hot coil box uncoiler. Background technique [0002] The uncoiling knife device of the hot coil box is the key part for dephosphorization of the steel coil before finishing rolling. The original uncoiling knife of the applicant is a full-open scraper, and the scraper is in direct contact with the surface of the strip during the uncoiling process. In the current use process, quality defects such as scratches on the surface of the strip are caused by the direct contact between the scraper and the surface of the strip. Chinese patent CN200520043578.1, the title of the invention is "Hot Coil Box Uncoiling Mechanism", which discloses a kind of uncoiling mechanism, including the shovel head connected to the fixed frame ... the second wheel, which is movably connected to the shovel head through the second connecting shaft. On the fixed frame, the second con...
