THE USE OF MODERN MATERIALS TO THERMALLY INSULATE THE HEARTH TUBES OF CONTINUOUS HEATING FURNACES IN A PLATE SHOP

摘要

A method is proposed for thermally insulating the hearth tubes of continuous heat-treatment furnace No. 3 in the plate shop at the Mariupol Metallurgical Combine with the use of ceramic fibers protected by refractory concrete. Results are presented from the use of furnace No. 3 with the experimental thermal insulation.
