Title:
IMPROVEMENT OF PERMEABLE REFRACTORY ELEMENT LIFE MOUNTED ON BOTTOM OF OXYGEN UPDRAFT TYPE STEEL CONVERTER
Document Type and Number:
Japanese Patent JPS5941412
Kind Code:
A
Abstract:
The service life of permeable refractory elements is improved by conserving in a vessel a fluid slag formed during refining of a charge after a liquid metal has been cast by tipping the vessel, depositing and spreading the slag over the bottom by bringing the vessel back to its upright position, and leaving the slag to harden and set on the bottom, while a sufficient pressure is maintained in the permeable refractory elements to ensure a permanent flow of a stirring fluid.
