A device for removing iron oxide and improving the detection rate of surface problems and its operation process

Abstract

The invention discloses a device for removing iron oxide and improving the detection rate of surface problems and its operation process. The device includes an ultra-thin strip casting and rolling process line, and is characterized in that it also includes an iron oxide powder collecting device, a compressed air pipeline, a High-pressure nozzle, air compression pump and steel strip to be cleaned, the steel strip to be cleaned advances along with the ultra-thin strip casting and rolling process line, and passes through the iron oxide powder collection device; the compressed air pipeline is arranged in the iron oxide powder Above and below the outlet of the powder collecting device, the compressed air pipeline is connected to an air compression pump; the high-pressure nozzle is arranged on the compressed air pipeline, and the nozzle of the high-pressure nozzle is connected to the surface of the steel strip to be cleaned at 30°. The device is suitable for ultra-thin strip products, which can ensure that the surface of the strip is clean, ensure the efficient use and accurate identification of the surface detector, and ensure a clean production environment.

Description

technical field [0001] The invention belongs to the technical field of Castrip steel strips (ie, ultra-thin strips), and in particular relates to a device for removing iron oxide and improving the detection rate of surface problems and an operation process thereof. Background technique [0002] In the prior art, compared with the conventional traditional hot coil, the ultra-thin strip greatly simplifies the process flow. The equipment length is 52m, which is only one tenth of the traditional hot rolling. Therefore, the descaling system in each process of hot continuous rolling is not Not set up in ultra-thin strip casting lines. As we all know, the iron oxide on the surface of the steel is generally composed of three kinds of iron oxides, from the inside to the outside are FeO, Fe 3 O 4 , Fe 2 O 3 , and most of the ultra-thin cast strips are in the protection of inert gas before rolling, and they are rolled in a single stand, so the time they are exposed to air in the hi...
