Walking Hearth Furnace
A walking hearth furnace is similar to a walking beam furnace but uses a hearth instead of beams. These furnaces are great for medium-size steelmaking processes.Walking Hearth furnaces allow the transportation and reheating of different sizes of material. Unfortunately, the back-face of the stock cannot be heated so that the stock residence time may be long. Consequently, the corrosion by scaling becomes important as well as abrasion. The temperature is generally around 1,250°C. Calderys has a full range of solutions: cast-in situ, plastic to cast/gun/ram, Quick Drying and Sol-Gel, Spraycast or Precast.
We conduct an extensive audit of your process to design a customised solution from the insulating castables, precast shapes and large range of ceramic anchors in our monolithics portfolio.
