Industrial Ovens & Furnaces #4558623

Calderys India has decades of experience in developing innovative monolithic refractory products and its applications techniques for reheating and heat treating furnaces of different sizes and capacities. Our offerings are based on energy saving solutions that improve the performance of the customer's equipment. We have sustained a long-lasting working relationship with the Steel industry (both FLAT AND LONG PRODUCTS) as well as OEMs based in India and oversees. We have been dealing with a wide range of furnaces: walking beam, walking hearth, pusher furnaces, and also rotary hearth, Tunnel Furnace, annealing and other thermal treatment furnace.We have unique experience of converting roof bricks in high capacity RHF to high performance Plastic Refractories. Today we are a reliable partner to all OEMs and users in India for designing, supplying and installing Plastic Refractories. We have a design, service and installation team with dedicated team of Engineers based at Nagpur, India.Subsequent to the merger with Calderys we have access to their innovative product range, global experience in Solution Providing, R&D know-how and design capabilities. Above strengths of Calderys India coupled with worldwide experience and presence of Calderys puts us in best position to be your partner to provide the most suitable and cost effective technical solutions that will attend to changes technological requirements as well as contribute to productivity and efficiency.

These types of moving hearth furnaces are preferred when stock size and geometry varies a lot. Here heat storage can be optimized by using humps and grooves. Unevenness of the stock exerts strong thermo mechanical stresses in the hearth blocks. It requires refractory which should be thermal stock resistant and at the same time should withstand impact of scale. Calderys India offers entire range refractory products for burners, walls, hearth banks, hearth, roof and waste gas flue duct of Rotary hearth furnaces.

The walking beam furnace offer distinctive advantages over others by allowing the heating of the back face of the stock. This also normally results in shorter heating time and shorter length of the furnace itself apart from operational flexibility. The temperature reaches upto 1250 C. Refractory here requires better thermal shock resistance and in certain areas are exposed to thermo-mechanical stresses. We offer complete range of refractories for such demanding application.

Simplicity of design, ease of construction and flexibility to accommodate different sizes of material are some of the few specialties in these types of Reheating Furnaces. Only limitation is the inability to heat the back face of the stock. In turn this leads longer residence time of stock inside furnace. From refractory angle, operating temperature and corrosion in presence of scales become important. Here again our products offer best lining solution.

In these types of furnaces stocks move down the length of the furnace. It involves less investment for installation as well as maintenance. Temperature generally goes upto 1250 C. Refractory wear in this type of furnace is mainly due to erosion of hearth and skid protection. Here again we offer solution for entire length of the furnace which includes burners, roof, hearth, soaking area and outlet slope.
