Abstract

The invention discloses an assembling and welding process of an inclined rail seat of a stepping type heating furnace, which comprises the following steps of: manufacturing a plurality of inclined rail seats; identifying one of the inclined rail seats; after inclined rail seat is identified and qualified, identifying to be a standard inclined rail seat; processing other inclined rail seats by adopting the standard inclined rail seat as a tooling of other inclined rail seats; and drilling and mounting antiskidding ribs at the bottoms of all the inclined rail seats. The invention can overcome the defects of low size precision and low yield in relevant technology and improve the required accuracy of an angle of the inclined rail seat.

Description

technical field [0001] The invention relates to a welding process for a ramp seat of a walking heating furnace. Background technique [0002] The ramp seat is a key part of the furnace bottom machinery of the walking heating furnace. It is located at the lower part of the lifting frame roller. The overall size and product quality of the ramp seat directly affect the operation of the entire heating furnace. The ramp seat is mainly composed of a first ramp seat and a second ramp seat. In order to ensure a uniform processing amount on the upper and lower surfaces, the deformation during the welding process must be controlled, and a reasonable welding process must be adopted to ensure the verticality between the steel plates and the flatness of the upper and lower surfaces to meet the processing size requirements. [0003] As for the related ramp seat, the first ramp seat is processed first, and other ramp seats are processed individually after passing the appraisal. There is n...
