Abstract

Blast Furnace is one of the major departments of VSP where the conversion of raw materials like Iron ore, Sinter and Coke into molten metal (Pig iron) takes place. To charge raw material into Blast Furnaces which are operated at 2 Kg/cm2 pressure Bell-less top (BLT) charging system supplied by M/s. PAULWURTH, LUXUMBURGE is provided.

In this project various mechanical equipment failures are studied and noted. Based on that failure analysis Sealing Valve failure is taken for further study, which is causing highest production loss to the company.

The function of all BLT equipment's studied and various probable causes for Sealing Valve failure are noted. Major causes contributing to the failure of Sealing Valve analysed and suitable alternatives are suggested.
