Improvement of material properties and cladded flat product productivity with roll-bonding technology

Taking advantage of the progress of roll-bonding technology,the integrity of the material technology,and the development of the production and examination facilities of all the main carbon steels,stainless steels and specialty alloys in Baosteel,the cladded flat new products,which combined both properties of base material and clad material,have been developed and produced in large quantities.The product categories includes heavy plates with high alloy content and homogeneous distribution in thickness and carbon steel plates cladded with all kinds of stainless steels,nickel alloys,and titanium alloys.The double-sided and single-sided cladding hot rolled strips and cold rolled sheets were also commercially produced.Due to the combined properties of both the cladding material and backing material,all products show obvious improvement in properties when compared with solid material.The comparability with the existing production process and equipment laid a very solid foundation for high productivity.
