Corrosion resistant treatment technology for carbon steel bracket

Abstract

The invention discloses a rust-resistant treatment process for a carbon steel bracket, comprising the following steps: material selection: selecting a carbon steel plate as a blank; heat treatment: annealing the selected steel plate, keeping the temperature at 650-720°C for 15 minutes, Cool in air to room temperature; then roll and form the steel plate to obtain a rough stent, remove the oxide skin and cool rapidly; machining; finish machining the rough stent to obtain the complete shape of the stent; oxide layer: make the stent Put it into the acid solution, soak it for more than 30 minutes, and finally take it out and rinse; surface treatment: spray flame on the surface of the oxide layer and add molten alloy particles into the flame to form a wear-resistant layer. The alloy particles are tungsten-cobalt alloy particles; Anti-rust surface treatment: Spray or roll anti-rust paint on the surface of the wear-resistant layer, and spray polyurethane varnish three times on the surface of the anti-rust paint. The invention effectively improves the antirust performance of the bracket and prolongs the service life of the product.

Description

Technical field [0001] The invention relates to the field of air-conditioning bracket manufacturing, in particular to a corrosion-resistant treatment process for a carbon steel bracket. Background technique [0002] With the rapid development of modern society, technological advancement has brought tremendous convenience to people’s lives. For example, in the hot summer, air conditioners have become an indispensable product for urban life, but most of the old floors have not been designed with special The outdoor unit of the air conditioner is placed on the platform. Therefore, most of the outdoor unit of the air conditioner is installed on the wall through a triangular outer unit bracket made of metal. After five to eight years of use, these triangle outer machine brackets will produce a lot of rust and the structure will no longer be stable, which will cause safety hazards. Summary of the invention [0003] The invention aims to provide a rust-resistant treatment process for a ...
