INFLUENCE OF BURDEN DISTRIBUTION ON EROSION OF BLASTFURNACE METAL RECEPTACLE

摘要

The influence of construction features of the valve-tapered (VNIIMETMACH - UZTM) and non-tapered loading devices was investigated as well as hot blasting supply in the circular bustle pipe on the burden uniformity and blast distribution along the circumference of 5000-5500 cu.m furnaces, formation of the coke column of poor mobility in the hearth and wear of the metal receptacle lining. Results of investigation can be used when developing the technology of melting in the large volume blast furnaces.
