Heat-treating furnaces are designed primarily to relieve stresses in metal castings. They alter the physical properties through controlled heating and cooling.
The refractories used in the heat-treating industry are selected for their ability to withstand exposure to high temperatures, resist thermal cycling, and maintain insulation. High alumina bricks, dense firebrick, and ceramic fiber products are used to construct furnace linings.
In areas of the furnace exposed to the highest temperatures or where rapid heating and cooling cycles occur, monolithic refractories such as castables and gunning mixes are frequently employed to ensure that the furnace lining remains intact and performs efficiently.
Larkin Refractory Solutions plays a critical role in providing heat-treating industry supplies and refractory materials designed to meet the demands of various furnace types. With a wide selection of high alumina bricks, dense firebricks, insulating firebricks, ceramic fibers, and monolithic refractories, Larkin ensures that heat-treating furnaces are well-equipped to handle the intense thermal conditions of the industry
