METHOD OF OPERATION OF RADIATION TUBE Russian patent published in 1998 - IPC

Abstract RU 2109212 C1

FIELD: tubular radiation heaters used to heat various heat-treating furnaces including those with controlled atmosphere and bath furnaces. SUBSTANCE: during preventive inspections of furnace radiation tube is turned through 180 deg about its longitudinal horizontal symmetry axis. Time intervals between turns are determined as 0.03-0.9 of specified period of operation of radiation tubes in given chamber ( section ) of furnace or for furnace as unit depending on temperatures dominating during thermal treatment of metal. Turning of radiation tubes through 180 deg makes it possible to prolong their service life by 1.5- 1.7 times. EFFECT: prolonged service life of radiation tubes . 1 cl
