For Heat Treating Industrial Valve Parts And Various Tool Steels

L&L Special Furnace Co., Inc., has supplied an electric box furnace to a plant located in Louisiana that is a global supplier of large industrial valves for various industries. This is the fifth L&L furnace supplied to this facility.

The furnace is used to both heat treat and temper various rings and seals deployed in the manufacturing of valves used in the power-generation field. It is also used for general heat treating of various steels prior to machining.

The furnace has an effective work zone of 34ā€ wide by 34ā€ high by 32ā€ deep. A complete digital control system, overtemperature protection and temperature recorder are included. There is also an audible alarm to signal an overtemperature or event condition along with a NEMA12 panel with fused disconnect. The furnace door is a horizontal-style door with a double pivot that allows for the hot face to be kept away from the operator.
All L&L furnaces can be configured with various options and be specifically tailored to meet your thermal needs. L&L also offers furnaces equipped with pyrometry packages to meet ASM2750E and soon-to-be-certified MedaCred guidelines.

Options include a variety of control and recorder configurations. A three-day, all-inclusive startup service is included with each system within the continental US and Canada. International startup and training service is available by factory quote.
