tube mill rolls hardening and tempering

  • Steel

    Steel is an alloy made up of iron with typically a few tenths of a percent of carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant need typically an additional 11% chromium.Because of its high tensile strength and low cost, steel is used in buildings

  • What is Induction Heating?

    Unlike some combustion methods, induction heating is precisely controllable regardless of batch size. Varying the current, voltage, and frequency through an induction coil results in fine-tuned engineered heating, perfect for precise applications like case hardening, hardening and tempering, annealing and other forms of heat treating.

  • Wallwork: Stress RelievingNormalising of Steels

    Carbon steels and alloy steels can be given two forms of stress relief: Treatment at typically 150-200C relieves peak stresses after hardening without significantly reducing hardness (e.g. case-hardened components, bearings, etc.): Treatment at typically 600-680C (e.g. after welding, machining etc.) provides virtually complete stress relief.

  • Hardening of Steel: Objectives and Components

    1. Main aim of hardening tools is to induce high hardness. The cutting property of the tool is directly proportional to the hardness of the steel. 2. Many machine parts and all tools are also hardened to achieve high wear resistance. Higher is the hardness, higher is the wear and abrasion resistance.
