Abstract: Electroslag surfacing with liquid metal ( ESS LM) technology is a new process to be based on current-con- ducting mould with special structure and use liquid metal pouring into the mould to carry out electroslag surfacing clad and get composite roll. The current status and development trend of domestic roll manufacturing industry and the principle and characteristics of electroslag surfacing with liquid metal technology are presented and described. Compared the ESS LM method with centrifugal casting method and casting preparing composite (CPC) method, the advantage and potentiality condition of ESS LM method are analyzed, and the development and application of ESS LM method to produce composite roll are introduced.
