Abstract

The invention discloses a rolling pretreatment process of a composite board, belonging to the technical field of composite board manufacture. The rolling pretreatment process comprises the steps of: forming a combined blank; respectively forming a gas inlet and a gas outlet in two ends of an interface of the combined blank; inflating an inert gas in the interface of the combined blank through the gas inlet; plugging the gas outlet; continuously inflating the inert gas, preserving the pressure under constant pressure; heating the combined blank; connecting the gas inlet with a vacuum pump, and vacuumizing; and arranging a gas storage bag communicated with the interface of the combined blank at the gas inlet, and sealing the interface of the combined blank by the gas storage bag. According to the rolling pretreatment process, the interface of the combined blank is avoided being oxidized; and meanwhile, during hot rolling, little gas remained between the interface of the combined blank and each of two layers of stainless steel interfaces is extruded into the gas storage bag with the movement of a roll and the combined blank, and thus the remained gas is avoided separating a parting agent or oxidizing the interface of the combined blank, and the binding quality of the composite board is ensured.

Description

technical field [0001] The invention belongs to the technical field of composite plate preparation, and in particular relates to a pretreatment process for composite plate rolling. Background technique [0002] Composite panels are made of carbon steel or low-alloy steel as the base layer and special materials such as stainless steel and titanium steel as the composite layer. In the fields of metallurgy and petrochemical industry. [0003] At present, the explosion method is mainly used to prepare composite panels. The explosion method can realize the composite of metals with widely different properties. However, the productivity, yield and dimensional accuracy of this method are low and the environmental pollution is serious. [0004] The vacuum rolling method is to make the base layer of carbon steel or low alloy steel and the multilayer of special materials such as stainless steel and titanium steel after blanking and surface treatment to make the surface in a physically...
