A metal surface heat treatment device and treatment method with self-diagnosis function

Abstract

The invention discloses a metal surface heat treatment device with a self-diagnostic function, which includes a frequency conversion fan, an air heater, an indirect image detection component, a camera standard calibration component, an activated carbon propulsion component, and a steam pipe isolation component, which can monitor the metal surface. Self-diagnosis of paint falling off has good promotion value.

Description

technical field [0001] The invention relates to the field of intelligent manufacturing and processing, in particular to a metal surface heat treatment device and a treatment method with a self-diagnosis function. Background technique [0002] In metal surface heat treatment, air convection heating is a relatively common treatment method. For some metals that are not easy to be directly exposed to the air for heat treatment, it is necessary to coat the metal surface with a paint layer before air convection heat treatment can be performed. Direct exposure causes problems such as decarburization. The current method of monitoring paint peeling is mainly the direct image method, that is, using the camera to directly obtain the image of the metal surface, using the color difference between the paint and the metal, and comparing and analyzing the paint peeling situation through the computer, but this method can only be used when the paint is already in a certain place. Only when ...

Problems solved by technology

Under the premise that the air pressure is basically unchanged, the main reasons for the paint falling off are as follows: 1. The spraying process is unqualified or the type of paint does not meet the requirements. The staff can be notified to deal with it by strengthening the spraying process or replacing the paint; 2. There is too much moisture in the air. As the temperature rises, the moisture will intensify the corrosion of the paint and cause it to fall off. There are two situations here, one The moisture content in the ambient air is already high, and activated carbon is usually added for drying at this time; the other is that in a heat treatment device equipped with a steam generator (generally used for surface oxidation of steel), the steam generator supplies steam The isolation butterfly valve of the pipe is not closed tightly, which causes the generator gas containing high moisture to be entrained when the air flows. At this time, it is necessary to isolate the relevant pipeline or manually tighten the isolation butterfly valve
