Method for avoiding cold rolled strip bonding and bonding-free hood-type annealing furnace

Abstract

A process for avoiding the bonding of cold rolling strip steel and a hood-type annealing furnace without bonding belong to the heat treatment field. The invention provides a process for avoiding the bonding of cold rolling strip steel aiming at the problem of strip steel bonding existing in the process that the hood-type annealing furnace is annealed for strip coils, controls the cooling speed of the strip coils from the inner ring of strip coils and the middle portion of strip coils to the outer ring of strip coils in turn. Simultaneously the invention provides a hood-type annealing furnace without bonding, which comprises a hood body which is fixed on the furnace platform, wherein a cooling system is axially arranged in the hood body, and the cooling system is fixed on the furnace platform. The phenomenon of bonding can be avoided through cooling down steel rings through the process of the invention, and the situation of waste product caused by the bonding of experimental steel ring is completely overcome. Simultaneously the purpose of non bonding can be well realized through placing steel ring into the hood-type annealing furnace of the invention, and the improvement on the original hood-type furnace can be carried out, therefore the process has the advantages of excellent benefits, favorable effect, less investment and expansive market prospect, and is beneficial for application and popularization.

AI Technical Summary

Benefits of technology

This patented technology allows for better control over how well metal rings are joined together by reducing any unwanted side reactions or residues that may occur during joining processes. By doing this, they become more reliable with longer lifespan compared to traditional methods like welded joints.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficiency of producing hot rolled lightweight materials such as aluminum or magnesium sheets through thermal treatments without causing damage from unwanted reactions with oxygen present on them' surfaces.
