Document Type and Number:
Japanese Patent JP2013517457
Kind Code:
A
Abstract:
A system and method for determining slag coating thickness and depth of refractory erosion of high temperature metallurgical furnace has been disclosed. The system senses and records certain furnace and slag related parameters such as slag chemistry, bath temperature, shell temperature, heat loss, refractory properties, jacket inlet water temperature, jacket outlet water temperature and water mass flow rate in the jacket and processes them in order to define a temperature profile and determine slag solidus of the slag. The temperature profile and the slag solidus are further used to determine the slag coating thickness and the depth of refractory erosion.
