Pig iron is usually transported to the steel mill in special containers such as torpedo ladle and pig iron ladle, which can vary considerably from plant to plant. Therefore, individual, creative refractory solutions are required - from highly adhesive mortars to insulation and maintenance mixes.
Torpedo Ladle is used over longer distances for transportation of pig iron from blast furnace to the steel plant. HI-TECH offers special gunning mixes for the spout area and for inside maintenance. These provide an extremely high flow rate and fulfil the strict criteria for operational safety requirements. A range of mortars carrying highly adhesive properties such as M80 can also be provided for use in walling applications for overhead bricklaying.
Pig iron ladle is most commonly used for hot metal transportation from the blast furnace. As it often used to fulfil several metallurgical tasks and secondary processing needs, it places severe demands on the refractory lining and materials.
HI-TECH has a rich experience and expertise of developing innovative monolithic refractory materials. We are able to offer reliable solutions to suit various application needs depending on individual customer requirements and plant parameters.For the iron ladle, we can provide refractory mixes for the permanent lining, wear lining and spout areas of the furnace.
HI-TECH offers a range of castables for use in the permanent lining zone of the iron ladle.
HI-TECH BackFill can be used as a repair mix over bricked permanent lining.
Gunning mixes with high wear resistance find excellent use in the spout region of the ladle.
HI-TECH ladle cleaning compound (Top and Bottom) helps in minimizing the ladle skull formation and provides the following additional benefits for the plant.
mooth de-skulling due to less skull generation
Prevents top ring formation at the ladle surface, facilitating better tapping and pouring
Increases frequency of ladle circulation cycle
Prevents direct exposure of liquid metal to outside atmosphere
Increases ladle capacity due to less skull formation
Prevents erosion of critical refractory lining, thus increasing the life of the ladle
Minimizes heat loss and maintains a uniform temperature profile
