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.Consolidating the advantages of the traditional technology "

The Sendzimir method consists of hot dip galvanizing before processing. The process consists of a treatment that involves the passage of the sheet metal in a bath of molten zinc at 650°. Before passing through the zinc, the sheet is subjected to a degreasing treatment to remove surface impurities and then pickled in hydrochloric acid to eliminate iron oxides. The total zinc thickness on both sides ranges from Z 200 to Z 275 g/m2 (UNI EN 10346).

Galvanic coatings offer triple protection to the steel underneath:

Protection by barrier effect: the coating insulates the steel from the external corrosive environment.
Cathodic or sacrificial protection: Zinc forms the anodic part in the corrosion stack and corrodes slowly protecting the steel. As long as there is zinc on the surface, the steel will not suffer any corrosion.
Sealing of uncovered areas: The zinc corrosion products, which are insoluble, compact and adherent, seal the areas of the steel which, for whatever reason (shocks, scratches, etc.), accidentally has been exposed to the external environment. This procedure provides additional protection for the substrate.

Research & Development Objective of " JJRS-Sendzimir"

Genuine heat regenerative non-oxidation heating

Waste heat "extreme recycling"

No end in energy conservation and environmental protection

Two Core of " JJRS-Sendzimir"

Compared with the traditional technology, " JJRS-Sendzimir" method can greatly increase productivity. For its:

• High temperature flame on-time heating technology: In the heating furnace, steel strips from the normal temperature of 20 C can be heated directly to the re-crystallization temperature zone of strip steel in the non-oxidation atmosphere.
• Zero heat preservation and energy saving concept: On the premise of guaranteeing the annealing and restoration effects, heat energy can be reasonably allocated, steel strip heating is conducted as far as possible in the flame heating section of high thermal efficiency to shorten the length of reduction section, so as to improve productivity as much as possible and reduce the manufacturing and operation cost of spare parts
