The operating temperature in a pusher furnace is generally up to 1250°C (for special steel grades like high silicon steel please contact us directly). The stocks (slabs, billets or blooms) move down the length of the furnace. These furnaces are quite popular due to the low installation and maintenance costs compared to other moving furnaces. Main damages are occurring on the refractory hearth by hot erosion and skids protections (hot erosion and mechanical destruction). Calderys has a full range of solutions: cast-in situ, plastic to cast/gun/ram, Quick Drying and Sol-Gel, Spraycast or Precast.
