01/ Use of compressed air

The use of compressed air in the steel industry is included in all production processes and is mainly divided into: process air and instrument air.

All of the above methods of air use have certain requirements on the quality of compressed air (particles, humidity, residual oil). A qualified adsorption compressed air dryer can ensure that the compressed air (PDP) ≤ -20 ℃ or even lower, to reduce the humidity in the compressed air plays a decisive role.

Therefore, adsorption compressed air dryer plays a very important role in the production process of steel enterprises. The following is the role of adsorption dryers in steel mills:

01Preventing corrosion of production equipment

During the steel production process, production equipment is often exposed to high humidity and is susceptible to corrosion. Adsorption compressed air dryer can effectively reduce the humidity in the compressed air, reducing the risk of equipment corrosion.

02Improve steel product quality

In steel manufacturing, compressed air humidity has a significant impact on product quality. Excessive humidity may lead to problems such as oxidation and rust on the product surface. By using an adsorption compressed air dryer, you can ensure that the compressed air used in the manufacturing process is dry and improve product quality.

03Increase production efficiency

The adsorption compressed air dryer can quickly reduce the humidity in the compressed air, preventing humidity-related problems in production. It can increase production efficiency and avoid production interruptions caused by humidity problems.

04Extend equipment life

The impact of humidity on production equipment cannot be ignored. Excessive humidity may lead to corrosion of the internal parts of the equipment, reducing the life of the equipment. By using adsorption compressed air dryers, the corrosion of the equipment can be reduced and the life of the equipment can be extended.

05Improve safety

In some steel production processes, moisture in compressed air may react with certain chemicals to produce dangerous gases. By keeping the compressed air dry, the generation of such dangerous gases can be reduced and the safety of the production process can be improved.

02/Cooperation with domestic steel mills projects

Wuhan Iron and Steel Group is the first large-scale iron and steel joint venture built after the founding of New China, which started construction in 1955 and was put into operation on September 13, 1958, and is an important state-owned backbone enterprise under the direct control of the Central Government and the State-owned Assets Supervision and Administration Commission of the State Council.

Since the early 1990s, Risheng has been cooperating with Wuhan Iron & Steel, and has supplied many sets of compressed air dryers with various specifications.

Since 2016, Risheng has provided dozens of large zero-consumption compressed air adsorption dryers to WISCO in response to WISCO's demand for energy-saving renovation of air pressure station equipment, and the quality and energy-saving benefits of the equipment have been well received by WISCO users.

Maanshan Iron and Steel Co., Ltd. is one of the extra-large iron and steel conglomerates in China and one of the largest industrial enterprises in Anhui Province. Maanshan Iron and Steel has 16 million tons of iron and steel supporting the production scale, total assets of nearly 90 billion yuan.

Since 2020, Jih-Sun has been cooperating with Maanshan Iron & Steel again, and has supplied several large zero-gas-consumption adsorption dryers. The on-site operation test fully meets the user's technical requirements and has brought substantial energy-saving benefits to Masteel.

03/Cooperation with foreign steel projects

Russian pipe producer United Metallurgical Corporation OMK is a backbone company in Russia, and its group subsidiary Vyksa Steel is currently the mainstay of welded pipe production in Russia and one of the oldest ferrous metallurgical companies in the country. In cooperation with Vyksa Steel, Jih-Sun Industries has customized two ultra-large zero-air-consumption adsorption dryers. In view of the outstanding energy-saving features of Risheng's technical solution, excellent structural design, and good reputation in the Yundong market, the customer agreed to ship the products before the inspection, which fully reflects their satisfaction and trust in Risheng's product technology and quality.

This project is two sets of large-scale blower adsorption dryer RSXB-4500ZP and front and rear end filters, which are used for anti-corrosion and dehumidification of steel plant equipment to prolong the equipment life. In this project, the blower adsorption dryer has more non-standard requirements, which is a great test of manufacturing process, technical level and design capability.

Risheng has been committed to the compressed air dryer for more than 30 years, and has provided customers with countless satisfactory products and design solutions, and won the trust of customers with high quality and high requirements. This project is no exception. We communicated with the customer in the early stage to satisfy the customer's needs, and discussed the design scheme with the technical department in the later stage to complete the project successfully. This project not only demonstrates Risheng Industry's high skill in manufacturing large-scale equipment, but also Risheng's commitment to quality. Every part and every process is strictly controlled to ensure the stability and efficiency of the equipment. Risheng's products are not only machines, but also the responsible attitude to customers.
