Reheating Firnace,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.
Design plan and construction drawings
Design scheme: our company has a design company with first-class qualification, and the designer has 30 years of experience in kiln design. After the drawing is completed, three experts (civil engineer, construction engineer and operating engineer) will carry out the final review of the drawing to ensure that there will be no mistakes in the construction of the kiln.
Construction drawing: The dimensions of each place are marked on the construction drawing, and the name, size and quantity of the refractory used are marked. Any experienced construction worker can understand the drawings and follow the construction without any mistakes.
Evaluation and preparation of refractory materials
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.
Acceptance and trial
1.. Whether the expansion joint is filled with insulation material, and whether the closed hole should be closed tightly;
2.. Whether the sand sealing groove is added to the sand according to the regulations;
3. Whether the mechanical kiln door and the damper lift are flexible, and whether the closing is tight and airtight.
