Brazing/hot-rolling technique for preparation of stainless steel carbon steel cladding plate

Aiming at the main problems in the explosion-rolling bonding process of stainless steel/carbon steel cladding plate, a new technique of brazing/hot-rolling method was put forward, and the effect of main process parameter on the bonding strength of brazing cladding plate was studied, and the bonding mechanics of hotrolling cladding plate was analyzed, and the main mechanical properties of cladding plate was tested.The results showed that an effective brazing bonding can be gotten by using home-made silver base solder.The oplimized processing parameters are as follows:brazing temperature is 755-770℃ and holding time is 2.5 -3 min.Soldered layer shows good plasticity during hot-rolling process.When the deformation rate was 40%, there was no fracture and lamination in soldered layer after rolling.Metallic bonding formed between the soldered layer and the base metal, and the bonding strength of the stainless steel/soldered interface obviously increased, and the shear strength of cladding plate after hot-rolling can be reached 342.6 MPa.
