METHOD FOR CONTROLLING AND AUTOMATIC CONTROL OF STABILITY OF FORMING OF SLAG LINING IN WALL-ADJACENT LAYER OF FURNACE Russian patent published in 2004 - IPC

FIELD: metallurgy.

SUBSTANCE: method includes adjustment of melt temperature by changing value of heat carrier flow into furnace, continuous supply of compressed air into furnace through open end of longitudinal branch pipe of tuyere, other end of which is covered by transparent body in form of cover placed coaxially to sensitive control element of device. As sensitive control element of device receiver of image of controlled image and brightness of slag lining is used. Image and brightness of slag lining is determined for different compounds and heat properties of melt, and time, enough for forming of slag lining. Determined values of time, brightness and image are taken as standard. Value of flow of heat carrier into furnace is changed until full coincidence of controlled image and brightness of slag lining to their standard values.

EFFECT: simplified operation.
