High temperature industrial furnace roof structure

摘要

A refractory brick for high temperature industrial furnace roof construction which accommodates hanger attachment at a plurality of locations along the length of the hanger brick. A high temperature industrial roof system having alternate rows of hanger bricks, of the above configuration, and filler bricks which are at least 2 1/2 times as wide as the hanger bricks and can be individually removed by lifting from the top of the furnace. The high temperature industrial furnace roof may be constructed of two configurations of refractories with shortening of the length of either configuration of refractory to accommodate designs having a wide variety of roof widths. Electrically heated furnaces have bus bars which run along the length of the furnace and are fed through the top of the furnace.
