Problems solved by technology
[0003] Most of the pre-buried channels in the prior art use Q235B base material, galvanized or alloy co-infiltration, multi-layer anti-corrosion coating and insulating sealing layer technology, but this technology has many defects. During the production, maintenance, transportation and installation of prefabricated components, The coating is easily damaged, and corrosion will occur during the construction process, greatly affecting the service life, high operation and maintenance costs, and safety risks; in addition, the galvanizing process is seriously polluted, and pollution is inevitable in the production of anti-corrosion coatings. The manufacture of new stainless steel pre- Buried channel is necessary and urgent

Abstract
The invention provides a processing technology of subway pre-embedded channel. Pre-embedded channels include C-shaped channels and cylindrical anchor rods. The processing technology of subway pre-embedded channels includes: selecting billets for heating and heat preservation; In the rolling process, the billet is solid-dissolved online to form the channel raw material; the channel raw material is straightened and pickled; the channel raw material is cut and punched according to the required size to form a C with mounting holes. shaped channel; the anchor rod passes through the installation hole and is riveted and fixed with the C-shaped channel to form the embedded channel; the surface strengthening treatment of the embedded channel is performed; Mold acceptance packaging. The processing technology of the subway pre-embedded channel breaks through many key technical problems such as low yield strength of raw materials, difficult hot rolling and processing technology of the pre-embedded channel by performing online solid solution at the same time in the rolling process, without galvanizing, green and low-carbon Environmental friendly.
Description
technical field [0001] The invention relates to the technical field of pre-embedded channels, in particular to a processing technology of subway pre-embedded channels. Background technique [0002] With the development of urban construction, more and more projects such as subway tunnels and municipal pipe corridors generally use prefabricated assembly structures. How to efficiently complete the laying and installation of various pipelines and equipment without damaging the structure is very important. [0003] The pre-embedded channels in the prior art mostly use Q235B base material, galvanized or alloy infiltration, multi-layer anti-corrosion coating and insulating sealing layer technology, but this technology has many defects, in the process of production, maintenance, transportation and installation of prefabricated components, The coating is very easy to be damaged, and corrosion will occur during the construction process, which greatly affects the service life, high op...
