Abstract：In order to meet the market demand of low-alloy steel plate with large single weight and ultra-heavy specifications, the experimental study of ultra-heavy steel plate produced by composite continuous casting slab was carried out by the rolling composite process. Ultra-heavy steel plates were obtained through rolling from composite slab. The comprehensive test and analysis show that the interface bonding of ultra-heavy steel plate produced by rolling composite process is good, and metallurgical bonding at atomic level is achieved with the sufficient recrystallization of grain at the bonding interface. The z-direction tensile properties meet the requirements of Z35, but the local reduction of area is low due to the existence of band-distributed oxides at the bonding interface microregion.
