HIGH-TEMPERATURE RESISTANT FURNACE BAR

摘要

PURPOSE: A high-temperature resistant furnace bar is provided to reduce costs by making the directly exposed portion of an incinerator with ceramic material and to lengthen the life span of the furnace bar by enduring the impact stress. CONSTITUTION: A ceramic material is pressurized in a metal frame structure(4) and is prevented from being damaged under impact stress. That is, the ceramic material absorbs the stress and is used in the metal frame structure. A furnace bar still has sufficient reliability in working even if the ceramic element is damaged. The temperature difference in the furnace bar is remarkably lower than one when the surface is covered by a single ceramic plate. Besides, the thermal stress is reduced to lengthen the life span of the furnace bar.
