Hot-rolling-bonding device

Abstract

The invention relates to the technical field of machinery, in particular to a hot-rolling-bonding device. The hot-rolling-bonding device comprises a base frame, an upper hot roll and a lower hot roll,wherein the upper hot roll and the lower hot roll are disposed in the base frame. A first air knife, a second air knife and a third air knife are perpendicularly installed on the base frame. The hot-rolling-bonding device has the beneficial effects that heating of the rolls is uniform and the heating time is shortened from original 3h to current 1.5h, and hydrogen materials are correspondingly reduced; three gas circuits of the first air knife, the second air knife and the third air knife are used for controlling, and flow management and control are facilitated; an integrated structure is achieved, installation is convenient, and the probability of misoperation of an operator is reduced; and the point position between the middle and bottom of the front side face of the upper hot roll andthe point position at the bottom of front side face of the upper hot roll are simultaneously heated and protected, and oxidation of the interface of a strip material is avoided.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a hot rolling compound device. Background technique [0002] Rolling compounding is divided into hot rolling compounding method and cold rolling compounding method. The process method of hot rolling compounding method is to heat the metal billet to be compounded to a certain temperature, apply a certain pressure to it to make rolling deformation, and heat Under the simultaneous action of pressure and force, a process method in which different metals are combined. [0003] In the hot-rolling cladding process, maintaining the roll temperature and the hot-rolling area in an oxygen-free environment are important factors affecting the bonding strength of the clad strip. The existing hot-rolling composite device has the following disadvantages: 1. The stability of the heating point is poor. The existing heating method is to connect the heating tube to the hot roll. When the operat...

AI Technical Summary

Problems solved by technology

The existing hot-rolling composite device has the following disadvantages: 1. The stability of the heating point is poor. The existing heating method is to connect the heating tube to the hot roll. When the operator replaces the hot roll, it is easy to misoperate and move the heating tube; 2. Few heating points lead to uneven heating of the roll; 3. Long heating time leads to a large amount of auxiliary material hydrogen; 4. The belt protection of the composite area is not in place, the interface of the composite strip is oxidized, and the composite strength is not strong
