Gerdau Jacksonville has purchased a material injection system from INTECO PTI to add carbon to the ladle after tap. The system stores carbon in an 870 cuft hopper, which is filled by super sack. Also included in the system is a 100 cuft vessel that holds 4000 lbs of carbon, along with the transport piping from the vessel to the ladle stirring area. A touch screen HMI positions a manipulator arm and selects the amount of material injected into the ladle, where the maximum amout of carbon that can be delivered is 200 lb/min. The manipulator arm then positions the transport pipe over the ladle stirring eye. The material injection system has many benefits, including the protection of operators by eliminating the handling of 50 lb bags. The new system will also increase the accuracy of the material added to the ladle, which will result in final carbon levels in the steel that are closer to the target specification.
