, where quallity is watchword, makes its foray in manufacturing of rolls with typical profiles. May it be section of raw material, heat treatment or machining, GALLIUM standards are set high to achive high precision, toughness, maximum wear resistance for greater productivity.
GALLIUM designs rolls on CAD stations with preferably edge and 'W' formation considering strain factors. The profiles are generated by special software (COPRA) and strip strain analysis is done to avoid any overloading at any stage during forming. Optimum strip width is calculated through the software to increase material yeildin strip processing line and to inprove weld quallity of tube.
Forged Alloy Tool Steels are used as roll material and are selectedin accordance with end use and functional requirements.Before processing the material is tested for soundness, chemical composition, grain size, carbide distribution, hardenability and inclusion ratings. Most modern methods of Ultrasonic testing, spectrum analysis and vedio image analysis are employed to confirm to GALLIUM stringent standards of quallity.
Close tolorance are being maintained from the very first processing stage using CNC Turning centers, CNC Vertical machining centers and gighly sophisticated bore grinder. Latest DNC system with appropriate softwre is used to avoid human error in machine programming.
Dimensional accuracies are maintained insuch a way that the parallelism between bore and profile and perpendicularity between the face and profile are within close tolerance to improve quality of end product.
Rolls are heat treated adopting a special process to achieve isotropic structure for maximum wear resistance properties and sufficient toughness to withstand high working loads. It also allows maximum number of regenerations without loosing much of wear resistant properties. Special care is taken to remove high points to reduce friction.
Each and every roll is inspected between processing by using sophisticated equipment, for dimensions, surface texture and micro structures.
