Intake duct cover for high-temperature heating equipment

We would like to introduce a case study of the duct cover for the intake and exhaust of high-temperature heating equipment manufactured by Mitsuya Corporation.

This product uses bonde steel plates for outdoor use. The cover frame for attaching to the main body cover is a sheet metal product made by assembling and welding four bent parts. Since the material is bonde steel plate, the welding bead has been minimized and finished by grinding. Inside, a rib cover with an incline is inserted into the end face of the cover frame to prevent hands or other objects from entering. By welding the rib cover components that extend outside the frame without welding from inside the frame, no welding beads are generated on the cover frame, resulting in an aesthetically pleasing duct cover. Because the welding is done outside the cover frame, there is no need to grind off the welding beads, which also reduces the labor required for finishing work.
