Abstract

Abstract: This paper introduces the function, structure and technical characteristics of lock-hopper which is the core device of large coal chemical equipment. Through manufacturing specifications, technical requirements and various process evaluations, reasonable and standardized technical parameters for molding and welding are determined. The paper also describes key technologies in detail including material control, welding method selection, transition layer surfacing, cover coat surfacing and heat treatment. The manufacturing process is controlled strictly and the welding quality of the equipment is guaranteed so as to complete the equipment manufacturing task successfully.

Key words: complex material, welding, overlay welding, transition layerr
