Title: Recoil system for furnace charger - absorbs momentum of bucket or compensates for over-ride
IPC: F27D17/00
Filed: 1975-11-10
Abstract: A hood constructed to envelope the upwardly opening mouth of a melting furnace has side walls and a roof and a section(s) which is hinged to swing outwards opening a lateral entry to the hood interior through which a charging bucket may be admitted to register with the mouth. A second section of the hood opposite the entry is mounted so as to slide towards and away from the entry and has a spring arrangement to resist movement of the second section away from the entry. The spring arrangement absorbs any lateral momentum of the bucket and returns the bucket after any over-ride of the furnace mouth into an accurate register with the mouth.
