After cooling, the slab or blank must be reheated and "softened" for the next molding operation (such as rolling, forging, or extrusion), and the method is rise the temperature to 1600 ° F to 2500 ° F. The process is carried out in a reheating furnace, which is a steel structure protected by the internal refractory. There are many different reheating furnace designs, including the most common and comprehensive types：walking-beamfurnace, walking-beam hearth, rotary hearth furnace, pusher type furnace and batch furnace. Each of these furnace types varies in length, capacity, width, temperature distribution and refractory design, depending on the configuration and temperature requirements of the product being heat treated.
Lite offers a wide range of products for these types of furnaces, such as low cement castables, plastics refractories, gunning mix and insulation castables.
For each of the designs, the service life of the refractory is predictable. But the same design can change dramatically due to different operations. Therefore, some furnaces require continuous maintenance. Our maintenance products include gunning mix, ramming mass, low cement castables and etc.
