Electric Resistance Melting Furnaces

FOR ALUMINUM AND MAGNESIUM

Introduction

Rayteq’s new high-powered, compact electric furnaces paired with advanced hybrid digital/analog controls slash energy costs by melting aluminum or magnesium right at the die casting machine or molding line, eliminating wasteful energy losses from hot metal transportation, launders and holding furnaces in central melt systems. Additional advantages include higher energy efficiency, less metal loss, fewer scrapped castings, no operator heat stress, no noise, all while virtually eliminating air quality issues. High furnace melting rates in a compact space are made possible by Rayteq’s unique high power density heating elements featuring new life-enhancing materials technology. Rayteq also supplies exact heating element replacements to incorporate this new technology into older electric furnaces.

Rayteq’s new DC Series electric furnaces are available in six standard sizes ranging in capacities from 700 lbs. to 3,250 lbs. of aluminum, and are supplied ready to operate with Rayteq’s Fleet Commander™ Interactive Demand Management System (IDMS™) which achieves additional utility cost savings by minimizing electric furnace fleet kW demand without impairing production rates or casting quality. Rayteq’s Fleet Commander™ software operates with all Rayteq electric melters as well as conventional electric furnaces equipped with Fleet Commander™ retrofit kits.
