Anti-Sticking Agent for Plated Strip Layer Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for separating different layers from plated strips are energy-intensive and costly, making them unsuitable for efficient recycling in industrial production.
Innovation Solution
A process involving the application of an anti-sticking agent, such as a ceramic oxide slip, to the contact surfaces of plates before rolling, allowing for easy separation of layers by preventing welding during thermal-mechanical treatment, followed by peeling of the cropped layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If thermal separation is used to separate different layers from plated strips, then separation can be achieved, but energy consumption becomes massive and investment in furnaces becomes costly
Solution Approach 1:
An anti-sticking agent is applied to the cropping areas of the plates before superimposition and rolling. This preliminary action prevents welding between layers during the rolling process, enabling easy separation of cropped layers without requiring subsequent thermal treatment or massive energy consumption.
Solution Approach 2:
An anti-sticking agent (intermediary substance) is introduced between the contacting surfaces of different metal layers. This intermediary prevents direct welding and bonding during rolling, allowing the cropped layers to be separated easily afterward without needing energy-intensive thermal separation processes.
2Ease of manufacture
If anti-sticking agent is applied to cropping areas, then layer separation becomes easy and cost-effective, but rolling operations must not be inhibited
Solution Approach 1:
The anti-sticking agent is applied specifically to the cropping areas (edges and ends) of the plates rather than the entire surface. This localized application provides separation capability where needed while maintaining proper bonding and rolling characteristics in the main body of the plates, thus not inhibiting rolling operations.
Solution Approach 2:
A slip comprising ceramic oxide in aqueous or organic solvent is used as the anti-sticking agent. This inexpensive, easily removable substance performs its function during rolling and can be easily eliminated or separated afterward, providing a cost-effective solution that doesn't compromise rolling efficiency.

AI summary
A process for the manufacture of plated strips comprising at least two layers of different metals or alloys. The process allows subsequent separation of different cropped layers resulting from shearing the plated strips. The process comprises preparing plates corresponding to each of the plating layers, superimposing and assembly of these plates to form a composite plate, hot and possibly cold rolling of this composite plate to obtain a plated strip, and shearing of cropping areas during or after rolling. In one embodiment, prior to superimposing the different plates, an anti-sticking agent is applied to the cropping areas of at least one of the surfaces of the plates which will be in contact with each other.
