Technical Field
[0001] This utility model relates to the field of heating furnace technology, specifically to a heating furnace for processing stainless steel cold-rolled strip. Background Technology
[0002] Stainless steel cold-rolled strip is made from hot-rolled stainless steel strip as raw material through further cold rolling. Compared with hot-rolled strip, it has higher dimensional accuracy, lower surface roughness, better surface quality, smoothness, and higher strength. During the processing of stainless steel cold-rolled strip, a heating furnace is required for heat treatment. Because iron filings and dust particles adhere to the surface of the steel, these residues will fall off during heating, accumulating inside the heating furnace and making cleaning and collection difficult. Therefore, a heating furnace for processing stainless steel cold-rolled strip is proposed to facilitate the cleaning and collection of these residues. Utility Model Content

Holding the handle and pulling it makes it easy to transfer the residue in the collection box.
[0006] Specifically, a heat insulation sleeve is fixed on the pull rod.
[0007] By adopting the above technical solution, the heat insulation sleeve can prevent hands from being burned.
[0008] Specifically, the collection box has a cleaning port on the side away from the handle, a vertical plate inside the cleaning port, a groove at the top of the collection box that matches the vertical plate, the groove communicating with the cleaning port, and the inner bottom wall of the collection box is sloped.
[0009] By adopting the above technical solution, the vertical plate is lifted to facilitate the discharge of residue collected in the collection box.
[0010] Specifically, a handle is fixed to the side of the vertical plate away from the handle.
[0011] By adopting the above technical solution, the handle makes it easy to pick up and put down the vertical panel.
[0012] Specifically, the guiding component includes side plates and guide rollers. There are two side plates, both of which are connected to the furnace body, and two guide rollers are rotatably connected between the two side plates.
[0013] By adopting the above technical solution, the arrangement of guide rollers and side plates facilitates the feeding of stainless steel cold-rolled strips into and out of the furnace.
[0014] Specifically, observation windows are provided on both sides of the furnace body, and vacuum glass is installed in both observation windows.
[0015] By adopting the above technical solution, the interior of the furnace can be easily observed through the observation window and vacuum glass.
