Abstract
Description
Technical Field
[0001] The utility model relates to a tool for online measuring the width of a blast furnace slag iron groove, belonging to the technical field of blast furnace production auxiliary tools. Background Art
[0002] Blast furnaces are becoming increasingly large, operating at high temperatures and pressures, with large tapping volumes, high temperatures, rapid flow rates, frequent tapping times, long durations, and heavy slag production. This high slag volume increases erosion and corrosion of the main tapping channel. Failure to accurately assess the extent of erosion could force the furnace to halt tapping, impacting smooth operation. Worse still, it could lead to iron leaks from the channel, burning out water pipes in the furnace foundation, oil pipes for furnace-mounted equipment, and cables, resulting in serious accidents such as blast furnace shutdowns. Currently, the degree of erosion in the main tapping channel of a blast furnace relies primarily on visual estimation using iron pipes. This results in significant errors and poses significant safety risks, necessitating improvements. Utility Model Content
