Excellent steel strip pickling line

2.0mm~4.5mm*1300mm 500000t/year

Beijing JJRS Technology Development Co., Ltd. registered in national high tech park-Beijing Economic and Technological Development Zone, is high-tech enterprise specialized in the complete set of metallurgical equipments, intensive processing of steel strip and metal surface coating engineering project, with the integration of mechanism, optics, electric and hydraulic pressure.

JJRS is professional on turn-key projects, from general planning, designing, to manufacturing, installing, commissioning and servicing. Besides, our business also covers single equipment’s designing, manufacturing and installing, as well as electric transmission, control system and spare parts. All basing on these supporting businesses, we mark out a developing strategy that taking metal strip intensive processing and color coating production lines as main, and the associated industry products as supplement.

Acid picking line is one of the important procedures in cold rolling steelstrip production technology, the aims of acid pickling are to remove the ferricoxide existing in steel strip surface, adjust weight of each coil, shear off chappededge to obtain qualified raw material for the next coming cold rolling process.According to different technique, acid pickling can be sorted into push-pulland continuous modes.

Push-Pull Shallow Trough Turbulence AcidPickling Line

The push-pull pickling line is to undertake each steel coil picklingseparately without welding, start up with push the steel strips and then pull.Usually this kind of pickling technology is suitable for those lines with annualcapacity lower than 600,000 ton, however our company adopts advanced shallow troughturbulence push-pull technology and the annual capacity could be up to1,000,000 ton. With the advantages of smaller location, less investment, moresimple equipment, more convenient operation, easier maintenance and well-adaptedfor various type of steel strip, our acid pickling line is well suitable forsmall and middle-sized cold rolling plants.

Continuous Acid Pickling Line

As a scientific research institution of JJRS Group, R&D center mainly research the latest metallurgic products, productive technology and equipment, introduce advanced foreign technology, improve production lien and equipment of high consumption and pollution. With the function of general engineer office, we organize technology seminar, plan and control the project schedule, examine and verify the bus lien and determine the technical dispute.

R&D center has applied and became “Beijing scientific and technological R & D organization”, by chief engineer and deputy chief engineer with bachelor or above degree, of which 1 professor and 2 master degree candidate.
The main works are as follows:

1,Be responsible for technical administration, market research and project process. Work out and revise the research and develop process, design process, manufacture process, installing process, commissioning process, training process, service process and inspection standard of all these process. File away documents, testing and operation specifications and issue it to the relational department to supervise and implement.

2,Improve the existing equipment, technology and recipe on the basis of market requirement, seek for new raw material, develop and design new products, research and manufacture the technology and products of energy conservation and environmental protection.

3,Study the latent demand of market and user, work out long-term planning and R&D budget according to requirement of company development, put forward and review the research direction and topic, and ensure the foresight, operability and feasibility.

4,Test and verify the technology and quality of new product after putting into production.

5,To realize the sales purpose gradually and provide the reliable basis, be responsible for collection, analysis, summary of technical information and document and transformation of technological achievements.

7,Provide the related department technical information, assist marketing center to promote market, negotiate technology, design and examine the technological proposal.

8,Declare patents, evaluate achievements and published articles.

9,Feedback to the production according to test and analysis result.

11,Establish and optimize quality systems, and be responsible for the product identification.
