Spreader – Fettling Machine

Machine developed for repairing Electric Arc Furnace (EAF) heart and banks areas at high temperatures (around 800 ºC).

It shall be fed with refractory mix big-bags by overcame, where can be used both valve big-bags and by ripping. The application of the material on the EAF button or banks made by lifting the machine inside the EAF by using a crane and operating its chute that round 360º. The material goes down from the machine through the chute by gravity. With both chute rotation and overcame translation, it is possible to repair any area of the heart and banks areas. Both operation of the chute and the material door (that releases the refractory mix) completely made by remote control (wireless or pneumatic control panel) that allows to the operator a perfect view of the areas to be repaired at a safe distance from the heat.
