Patent for circulating pickling device for hot-rolled titanium plate, promoting efficient development of the industry!

Update time  2025-07-25 Reading 248

1、 Technological Core and Innovation Breakthrough

1. Full process automation design

The patented device integrates core modules such as feeding mechanism, acid washing box, washing mechanism, and spray system, which can handle titanium plates of different thicknesses. Among them, the washing mechanism combines mechanical brushing with acid immersion to quickly peel off the oxide scale on the surface of the titanium plate, with an efficiency increase of more than 30% compared to traditional processes; The acid resistant conveyor belt synchronously removes oxide impurities generated during the acid washing process to avoid secondary pollution.

2. Acid circulation and precise control

The acid scraping mechanism uses multiple sets of elastic scrapers to accurately remove residual acid on the surface of the titanium plate, reducing acid consumption by about 15%;   

The mixing tank body optimizes the acid solution ratio through an intelligent mixing system to ensure concentration uniformity and avoid over pickling or under pickling problems caused by acid imbalance;   

The spray mechanism is linked with the conveyor belt cleaning brush to achieve acid recycling and equipment self-cleaning, reducing water consumption by more than 20%.

3. Environmental protection and energy efficiency optimization

The device reduces waste acid emissions through a closed loop system, combined with advanced water treatment technology, achieving a water resource recycling rate of over 90%. In addition, new technologies such as microwave heating are used for acid heating, which reduces energy consumption by 40% compared to traditional boiler heating and significantly reduces carbon emissions.

2、 Industry impact and application value

1. Improve production efficiency and product quality

This patent solves the problem of surface defects caused by incomplete removal of oxide scale and residual acid solution in traditional pickling processes. Taking Shengyang Metal as an example, the surface roughness control accuracy of its pure titanium plate has been improved to ± 0.05mm, and the yield rate has increased from 85% to 92%. The comprehensive performance of the product has reached the international leading level.

2. Promote the upgrading of green manufacturing

Shengyang Group has achieved acid recycling on the solid solution pickling line through this patented technology, reducing the amount of waste acid treatment by 60%. At the same time, it adopts supporting technologies such as low-temperature denitrification and plastic fired plate dust removal, resulting in dust and nitrogen oxide emissions that are 50% lower than the national standard, becoming a green benchmark in the industry.

3. Strengthen the competitiveness of the industrial chain

As the single champion of manufacturing industry in Shandong Province, Shengyang Metal has achieved the highest production of pure titanium plates in China with this patented technology, and has successfully entered high-end fields such as aerospace and marine engineering. In 2023, the company's titanium plate exports increased by 40% year-on-year, driving the transformation of the domestic titanium processing industry towards high added value.

3、 Technology Extension and Industry Trends

1. Collaborative innovation of processes

This patent complements Shengyang's existing technology: for example, its "titanium plate hot rolling scale preparation method" combined with cyclic acid washing technology achieves full process optimization from rolling to surface treatment, reducing production costs by 18%.

2. Integration of intelligence and digitization

The device can integrate the industrial Internet platform, and dynamically adjust the process parameters through real-time monitoring of acid concentration, temperature and other parameters, combined with AI algorithm. This "data-driven" mode has been applied on the Shengyang intelligent production line, which has increased the efficiency of the pickling section by 12% and improved the quality stability by 25%.

3. Leading by industry standards

This patented technology provides a technical basis for the development of industry standards for titanium plate pickling. At present, Shengyang is collaborating with industry associations to promote the revision of the "Acid Cleaning Process Specification for Titanium and Titanium Alloy Hot Rolled Plates", which is expected to include cyclic acid cleaning technology in national standards and accelerate the overall upgrading of the industry.

4、 Future development direction

1. Expand application scenarios

Shengyang plans to extend this technology from titanium plates to high-end materials such as stainless steel composite plates and nickel based alloys. It is expected that the production capacity of related products will increase by 50% by 2025, further consolidating its leading position in the special steel field.

2. Deepen international cooperation

Relying on the "the Belt and Road" initiative, Shengyang is negotiating technology output and capacity cooperation with enterprises in Southeast Asia, the Middle East and other places to promote China's titanium processing technology standards to the world.

3. Technological iteration and upgrading

Next, Shengyang will explore the integration of electrochemical acid washing and nano coating protection technology, aiming to shorten the acid washing time to one-third of traditional processes and improve the corrosion resistance of titanium plates by 3-5 times, providing solutions for extreme environmental applications such as deep-sea equipment and nuclear power.
