L&L Special Furnace has delivered a highly uniform box furnace to a distributor of equipment to maintenance repair and overhaul (MRO) facilities located throughout the world.
The L&L Model XLB124 has working dimensions of 11” wide by 10” high by 22” deep. The furnace is capable of heat-treating a wide variety of tool steels – from D-2 to high-speed M-2 tool steel, along with low-temperature tempering. It is equipped with a sealed case for inert atmosphere capability, as well as a fully functional atmosphere control panel with pressure regulator, flowmeter, and manual shut-off valve.
Elements are very evenly spaced around the chamber. There is a manually operated, spring-assisted vertical door. Included is a NEMA 1 control cabinet with a Eurotherm program controller, high-limit backup system, thermocouples, fusing, and all interconnection wiring. Power control is accomplished with quiet two-zone, long-lasting solid-state contactors. The furnace hearth is a rugged cordierite plate with ceramic support.
The Model XLB124 is insulated with 2-1/2” lightweight firebrick and backed up with 2” of insulating board. The bottom is reinforced with a high-density calcium silicate that provides extra support for the load weight.
The L&L XLB series comes in several sizes, with custom configurations available upon request. There are also many options available for the XLB series, from atmosphere-sealed casing for use with inert atmosphere to an array of control and recorder varieties, along with recirculation fans and controlled cooling.
If precise temperature control and uniformity are key to your process, then L&L’s XLB series is a great choice.
