A Midwest manufacturer expands their heat treat capabilities with a dual chamber furnace. With this furnace, the manufacturer will heat treat their small tool steel parts in-house in a timely manner.
The supplier, Lucifer Furnaces, identifies that the furnace, a Model RD8-KHE18, is a space saving dual chamber unit with working dimensions of 12”H x 14”W x 18”L in both upper and lower chambers. The upper hardening chamber is rated up to 2200°F while the lower convection oven tempers up to 1200°F.
This specific unit was customized with a programmable controller with an overtemp safety system for the upper chamber as well as a 7-day timer with alarm for audible event notification. Both chambers are lined with a multilayered 4.5″ combination of lightweight firebrick hotface insulation and mineral wool backup insulation for energy efficient operation. The firebrick is precision dry fit inside the chamber with staggered seams for reduced heat loss while allowing for thermal expansion.
