Steel Profiles - 3

23 > Drawing a steel profile ZOLLERN ISOPROFILs steel sections are produced in close collaboration withcustomers from a wide range of industries and are designed to meet specific construction and fabrication requirements.Components with complicated shaping and high load-bearing capacity are the ideal application for precision-shaped profiles. > The fabrication processes used by ZOLLERN ISOPROFIL for profile manufacture increase the strength of materials by means of specifically targeted cold working and heat treatment,and also improve the machining properties,as required.The fabrication...

Heat treatment gives the material specific properties for its use or further processing. ZOLLERN ISOPROFIL has annealing facilities which can be used to carry out all forms of heat treatment on steel profiles in-house.The various processes of heat treatment are as follows: 1011 > Here the metal is heated up to the Ac1transformation point at about 720 C.Sub- sequent slow cooling produces a soft, stress-relieved state.Simultaneous conver- sion of the carbides into spheroidised form significantly improves subsequent machining or chipless cold forming. Normalising comes about through heating...

Induction hardening machine to harden cold drawn steel profiles with cross sections of up to 4000 mm 2 andspecified lengths from 2200 mm up to 9000 mm. Effective hardening depths of 0.5 up to 5.0 mm are possible. As well as hardening the ZOLLERN steel profiles,we will also process on sub-contract basis. 1213 Application Examples: Linear guides,transmission system components,torsion bars,splined shafts, chain guides,knife blades,spring mechanisms,etc. Induction Hardening provides technical and cost advantages over conventional methods: > Induction Hardened Profiles can be in lengths of up to...
