Lucifer Furnaces, Warrington, Pa., reports that it has delivered a dual-chamber high-temperature furnace to Compacting Tooling Inc., McKeesport, Pa., to heat treat Crucible particle metallurgy (CPM) high speed steel tooling. Powered with 42 kW, this furnace is ideal for heat treating high-speed steel, as it reaches 2450°F in the upper chamber and 1200°F in the lower tempering oven.
A combined 6.5 inches of ceramic fiber modules with mineral wood backup insulation allows for faster heating/cooling cycles. Silicon carbide heating elements operate off-the-line through an SCR power supply with a current limiting circuit that automatically adjusts the voltage to elements as their resistance increases, resulting in longer element life.
Heat treating recipes can be stored in the Honeywell digital temperature controllers with a seven-day timer. High limit controllers were added for safety.
CTI, an ISO 9001-2008 certified shop, is a specialized Tool & Die company manufacturing high-quality tooling for the powder compaction industry. CTI does most of its heat treating in-house for faster turnaround. This furnace will supplement the other Lucifer furnaces currently in use.
