1. Molder tool for ramming up and compacting mold material in a purely manual fashion (see Ramming).
Depending on the shape of the ramming tip, hand rammers are available as pegging rammers and bench rammers made of wood or metal or with solid-rubber ramming heads (see Fig. 1). For large molds, pneumatic rammers are used.
2. Ramming tool for compacting refractory ramming masses for lining melting furnaces, in particular crucible furnaces. The refractory ramming mass is filled into a gap between the furnace brick lining and the ramming templates and compacted by means of hand or pneumatic rammers. One example of a rammer foot is shown in Fig. 2.
