Title:
CONVENIENT SCOURING MELTING CASTING FURNACE
Document Type and Number:
Japanese Patent JP3541312
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a metal melting, scouring furnace suitable for training in school.
SOLUTION: The scouring furnace using two welders further uses two elevators (jacks in Fig. 1) and arc is generated from above and below a graphite crucible fixed with a ladle base separate from the structure of the furnace using upper and lower electrodes. Consequently, copper (having a melting point of 1,083°C) is scoured through reduction melting easily from an oxide in the sense of welding and can be cast immediately into a product without requiring reheat. The inventive furnace combines three functions of reduction scouring, metal melting and casting.
