Information
Jiangsu Nanyang Machinery Manufacturing Co., Ltd. is a professional design and manufacture of various types of high-frequency welded pipe units, stainless steel precision welded pipe units, high-precision steel-plastic and stainless steel composite welded pipe units; design and manufacture of various specifications and types of welded pipe molds - rolls, special-shaped rolls The precision roller manufacturers enjoy high reputation among domestic and foreign merchants.
(1) According to the manufacturing materials: cast steel series rolls, cast iron series rolls and forged series rolls
(2) Types of heat treatment commonly used for rolls: stress relief annealing, isothermal spheroidizing annealing, diffusion annealing, normalizing, tempering, quenching, and cryogenic treatment.
(3) The overall roll is relative to the composite roll. The outer layer of the roll body and the core part and the roll neck are cast or forged by a single material. The outer structure of the roll body and the roll neck are different. Or forging process and heat treatment process to control and adjust. Both forged rolls and statically cast rolls are integral rolls. The integral rolls are divided into two types: integral casting and integral forging rolls;
(4) Metallurgical composite casting rolls mainly include three-flush composite casting, overflow (full flushing) composite casting, centrifugal composite casting, in addition to CPC-Continuous Pouring Process for Cladding, spray deposition, Types of composite rolls manufactured by special composite methods such as HIP-Hot Isostatically Pressed and electroslag welding. The combined rolls are mainly inlaid combination rolls.
