Hardening of slewing rings
Wind is the ideal energy source. It’s safe, it’s clean, and there’s an endless supply. But harvesting and converting it into electricity poses challenges. The large slewing bearings used in wind turbines, for example, are subject to extreme loads and near-constant operation. Such conditions mean the slewing rings must be hardened without producing so-called ‘soft spots’ or ‘soft zones’. These zones are caused by unintentionally heating already hardened areas—in effect tempering, or softening, the metal.
