Abstract

The improvement in top and bottom-fired walking beam furnaces wherein the lower burners, like the top ones, fire opposite to the direction of travel of the work pieces from the charging to the discharge end of the furnace. This is accomplished by the use of a plurality of parallel walking beam assemblies, each of which has two spaced stationary water-cooled beam sections having a supporting rail along the top. The bottoms of these side pieces are rigidly integrated through a bottom water-cooled beam section. There is an idler beam section supported for longitudinal motion above the bottom beam section, longitudinal travel of which in one direction raises the idler section and in the opposite direction lowers it. There is a longitudinally-movable traversing beam section having a load-traversing rail at its top which is lifted above the support rails on the side beam members when the idler beam raises, but which is normally lower than the support rails. After the traversing beam is raised it is moved longitudinally toward the discharge end of the furnace and when it is lowered it is returned to its normal position. Combined tie rods and spacers at intervals along the assembly connect the upper portions of the side beam sections so that the girder is in effect a box section within which are the walking beam elements. Mechanism outside the furnace at one end moves the idler beam section and at the opposite end moves the traversing beam member, and each holds its beam against endwise travel when the other is moving.
