Railway bridge steel frame spraying assembly line application case

Case background

A railway bridge construction company has undertaken the construction of many large railway bridges. The railway bridge steel frames it produces need to have high-strength anti-corrosion performance and a long service life. The traditional spraying process is inefficient, unstable in quality, and has potential risks to the environment and workers' health. Therefore, the company decided to introduce advanced railway bridge steel frame spraying assembly line equipment to improve production efficiency and product quality.

Challenges

Low efficiency of traditional spraying: Manual spraying is slow and difficult to meet the needs of mass production.

Unstable quality: Manual spraying is difficult to ensure uniform coating, which affects the appearance and protective performance of the product.

Environmental and health risks: The traditional spraying process emits a lot of volatile organic compounds (VOCs), which is harmful to the environment and workers' health.

Cost control: High labor costs and low utilization of traditional spraying materials increase production costs.

Solution

In August 2024, after in-depth cooperation with Zhan Yao Coating, the company introduced a set of advanced railway bridge steel frame spraying line equipment. The equipment has the following features:

Full process automation: including pre-treatment equipment, powder spraying system, curing system, drying system, heat source system, electronic control system, hanging conveyor chain, etc., to achieve fully automated operation from workpiece loading to finished product unloading.

Efficient spraying system: adopts large-scale wind spraying system, with a powder recovery rate of up to 99%, significantly improving the utilization rate of coatings.

Intelligent control: equipped with PLC intelligent control system, it can realize automatic color change and fast color change (10 to 15 minutes) to meet the color requirements of different products.

Environmental design: perfect exhaust gas treatment system, effectively remove harmful gases and dust generated during spraying, and ensure clean workshop air.

Anti-corrosion process: adopt arc spraying aluminum long-term anti-corrosion technology, which can extend the overhaul cycle of railway bridges, reduce maintenance costs, and predict a service life of more than 30 years.

Application scenarios

The railway bridge steel frame spraying line is widely used in railway bridge construction, municipal engineering and other fields, and is particularly suitable for mass production of railway bridge steel frames, railing brackets and other products. The equipment can significantly improve production efficiency, improve product quality, and reduce labor costs and environmental impact.

Customer feedback

Since the railway bridge steel frame spraying production line was put into use, the company's production efficiency has been significantly improved and product quality has reached a new height. The person in charge of the company said: "The spraying production line equipment provided by Zhan Yao Coating not only solved the spraying problems we have faced for a long time, but also improved our brand image and market competitiveness. We are very satisfied with the professional service and technical strength of Zhan Yao Coating, and will continue to maintain a long-term and stable cooperative relationship in the future."
