Abstract

An apparatus and method for transferring the coiled hot steel sheet without reel from coiling station to decoiling station is disclosed. Said apparatus has the parallelly arranged supporting rollers, floating supporting rollers pivoted to hydraulic cylinders (one for each) and pushing rollers pivoted to hydraulic cylinders (one for each). Under the drive of motor, said all rollers can be synchronously lifting or lowering and rotating to trasfering the coiled steel sheet.

Description

Technical field [0001] The invention relates to a device for transferring objects and a method for transferring objects using the device, in particular to a device and method for transferring hot coil box steel coils. Background technique [0002] The traditional hot coil box uses the rotation of the transfer arm with the mandrel to complete the transfer process of the steel coil. During the transfer process, the mandrel contacts the inner ring of the steel coil. Since the inside of the mandrel is cooled by cooling water, the inner ring of the steel coil will be damaged. The temperature drops too fast, so that the temperature difference between the head and the tail of the strip is too large, which affects the thin plate (or strip) rolled by the finishing mill. The long tail is unqualified in terms of thickness, shape, and mechanical properties, which affects the product. quality and cause an increase in production costs. Contents of the invention [0003] In order to ove...
