01/ Use of compressed air

In steel enterprises, compressed air is used throughout various production processes, primarily categorized into: process air and instrument air.

Both of these applications require compressed air to meet specific quality standards (such as particulate matter, humidity, and residual oil). A qualified adsorption compressed air dryer ensures that the compressed air's pressure dew point (PDP) is ≤ -20°C or even lower, playing a crucial role in reducing the humidity in the compressed air. Therefore, the adsorption compressed air dryer plays a very important role in the production process of steel enterprises. Below are the key functions of the adsorption dryer in steel plants:

01 Preventing Equipment Corrosion

In the steel production process, equipment is often exposed to environments with high humidity, which makes it susceptible to corrosion. An adsorption compressed air dryer effectively reduces the humidity in the compressed air, minimizing the risk of equipment corrosion.

02 Improving Steel Product Quality

In steel manufacturing, the humidity in compressed air significantly impacts product quality. Excessive humidity can cause issues such as oxidation and rust on the product surface. By using an adsorption compressed air dryer, the compressed air used in production can be effectively dried, thus enhancing product quality.

03 Increasing Production Efficiency

An adsorption compressed air dryer quickly reduces the humidity in compressed air, preventing humidity-related issues during production. This boosts production efficiency by avoiding interruptions caused by moisture-related problems.

04 Extending Equipment Lifespan

The impact of humidity on production equipment should not be underestimated. Excessive moisture can cause internal components to corrode, shortening the lifespan of the equipment. By using an adsorption compressed air dryer, corrosion can be minimized, extending the service life of the equipment.

05 Enhancing Safety

In certain steel production processes, moisture in compressed air can react with chemicals to produce hazardous gases. By keeping compressed air dry, the generation of such dangerous gases is minimized, thus improving safety during production.

02 / Collaboration with Domestic Steel Plant Projects

WISCO Group is the first large-scale steel conglomerate established after the founding of New China. Construction began in 1955, and it was completed and put into operation on September 13, 1958. It is a key state-owned enterprise directly supervised by the Central Government and the State-owned Assets Supervision and Administration Commission (SASAC) of the State Council.

Since the early 1990s, RISHENG has been collaborating with WISCO, providing multiple sets of compressed air dryers in various models and specifications over the years.

Since 2016, in response to WISCO's need for energy-saving upgrades to their air compressor station equipment, RISHENG has supplied dozens of large-scale, zero-gas-consumption adsorption compressed air dryers. These devices have been widely praised by WISCO users for their high quality and energy-saving benefits.

Ma'anshan Iron and Steel Co., Ltd. is one of China's large-scale steel conglomerates and one of the largest industrial enterprises in Anhui Province. Ma'anshan Steel has an integrated production capacity of 16 million tons of iron and steel products, with total assets nearing 90 billion yuan.

Since 2020, RISHENG has been collaborating with Ma'anshan Steel, providing multiple large-scale zero-gas-consumption adsorption dryers. On-site performance tests have fully met the user's technical requirements and have brought substantial energy-saving benefits to Ma'anshan Steel.

03 / Collaboration with International Steel Plant Projects

The United Metallurgical Company (OMK), a leading Russian steel pipe manufacturer, is a key player in Russia’s industrial sector. Its subsidiary, Vyksa Steel, is one of the country's largest producers of welded pipes and one of the oldest ferrous metallurgy companies in Russia. In collaboration with Vyksa Steel, RISHENG customized two ultra-large, zero-gas-consumption adsorption dryers. Thanks to the outstanding energy-saving features, excellent structural design, and RISHENG’s solid reputation in the market, the customer agreed to ship the equipment without an on-site inspection, demonstrating their satisfaction and trust in RISHENG’s product quality and craftsmanship.

The project involves two large centrifugal adsorption dryers (RSXB-4500ZP) along with front-end and rear-end filters, aimed at preventing corrosion and dehumidifying steel plant equipment to extend its service life. The centrifugal dryers for this project had many non-standard requirements, which posed a significant challenge to our manufacturing processes, technical expertise, and design capabilities.

RISHENG has been committed to manufacturing compressed air dryers for over thirty years, delivering countless successful products and design solutions, and earning customer trust with our high-quality standards. This project was no exception. We began by thoroughly communicating with the customer to understand their needs, and then worked closely with the technical department and other teams to finalize the design and successfully complete the project. This project not only demonstrates RISHENG’s expertise in manufacturing large-scale equipment but also highlights our commitment to quality. Every component and every step of the process was meticulously controlled to ensure the stability and efficiency of the equipment. The products we provide are not just machines; they are a reflection of our responsibility and dedication to our customers.
