Problems solved by technology

[0023] Since the steel coils are stacked vertically when heated in the bell annealing furnace, these steel coils with overflow edge defects will cause severe crushing and bonding at the overflow edge, and normal production cannot be carried out in the next leveling unit

Embodiment Construction

[0061] Referring to Figures 1 to 3, the method for preventing deviation and coil overflow of the electrolytic cleaning unit of the strip steel of the present invention when running at high speed, the electrolytic cleaning unit of the strip steel consists of a roll system such as an uncoiling section, a process cleaning section, and a tension coiling section. Among them, the process cleaning section includes a pre-cleaning tank, a silicon coating tank, a scrubbing tank and a rinsing tank, in which the entrance grounding roll 1, the front steering roll 2 of the immersion roll, the immersion roll 3 of the silicon coating tank, and the rear steering roll of the immersion roll of the silicon coating tank are arranged in sequence. 4. Rinsing immersion roll 5 (two); the tension coiling section includes the exit grounding roll 6 of the process cleaning section, the rear steering roll 7 after the grounding roll, tension rolls 81-84, and the front steering roll 9 of the coiler (two);

Abstract

A method for preventing band steel electrolyzed cleaner set running from offset and overflow is optimized. The band steel electrolyzed cleaner set consists of unwind section, cleaning section and tension coiling section, roller's shaped is optimized designed. Cleaning section entrance, exist grounding roller and front steering roller of coiler adopt sinusoidal curved roller and medium projected, roller material is chromium plated on surface; front steering roller of silicon-coated slot for cleaning section contacting liquid, submerged roller of silicon-coated slot and submerged roller of spraying slot adopt sinusoidal curved roller and medium projected; roller-side rubber, ring-opening slot and rear steering roller of silicon-coated slot adopt planar roller, roller-side material, ring-opening slot, front steering roller of silicon-coated slot and coiling section roller are sinusoidal curved roller and medium projected, roller side is made of polyurethane urea ring-opening slot. It's simple and convenient.

Description

technical field [0001] The invention belongs to the field of steel rolling equipment, and in particular relates to a process method and equipment of a cold-rolled strip electrolytic cleaning unit. Background technique [0002] The cold-rolled strip electrolytic cleaning units of domestic and foreign iron and steel enterprises are all composed of uncoiling, process cleaning and tension coiling equipment. Among them, the roll system equipment has no effect on whether the strip can run stably in the process cleaning section and coiling section. Whether the coiled steel coil can obtain a higher required coiling quality (especially the electrolytic cleaning units in various steel mills in the world have a tendency to develop at a high speed) is often solved by the following two methods of: [0003] 1. Set several sets of correction devices (CPC devices) that can automatically track and correct the deviation of the strip at the entrance, exit and coiling section of the process cl...
