Zink Körner starts up high-efficiency galvanizing plant in Russia
Eco-conscious batch galvanizing: Follow-up order from Tochinvest demonstrates successful cooperation
Zink Körner starts up high-efficiency galvanizing plant in Russia(firmenpresse) - In 2012, Tochinvest Zinc, a leading manufacturer of steel parts in Russia, installed a new hot-dip galvanizing furnace from Zink Körner. Last February, Zink Körner received the FAC for the plant.
The successful operation of the first galvanizing shop was reason for JSC Tochinvest to establish the Tochinvest Zinc division in 2011. This event also marked the kick-off of a new project, namely the construction of a further galvanizing plant in Ryazan, some 100 km to the southeast of Moscow.
For this project, Zink Körner supplied the galvanizing furnace, complete with the housing, and the drying furnace. The tank is 13.0 m long, 1.8 m wide and 3.2 m deep. The new facilities were started up at the beginning of 2013. With trial operation running smoothly, already in February Tochinvest issued the Final Acceptance Certificate for the new plant.
Tochinvest Zinc specializes in the manufacture of crash barriers and bridge railings. The company also offers job galvanizing services for steel parts as diverse as lamp posts, traffic signs, barriers and customized steel structures for use in road construction.
The new furnace can galvanize up to 15 t/h. Assuming three-shift operation during 250 days of the year, Tochinvest Zinc will be able to produce 80,000 t annually. This makes Tochinvest Zinc the most productive galvanizing plant in Russia.
Already in 2007, Tochinvest, a leading manufacturer of steel parts in Russia, had built a hot-dip galvanizing plant. Also for that plant, Zink Körner had supplied the galvanizing furnace, including the housing, and the drying furnace. That furnace is 7.0 m long, 1.5 m wide and 2.5 m deep. Right from the first day of operation, the galvanizing quality had been in compliance with the Russian GOST 9.307-89 standard and the international standard ISO 9001:2000.
The recently built furnace features flat flame burners of the FL 20/50 type, which Körner developed specifically for batch galvanizing. These burners use natural gas as fuel, which is available at relatively moderate cost. Their design allows them to provide the same smooth and mild heating as previously only achievable by electrically heated furnaces.
The burners achieve an efficiency of 75 percent. This makes Zink Körner a market leader also in terms of energy efficiency. Unlike burners commonly used in the past, they operate in a modulating mode that makes them infinitely adjustable within a range of 1:10.
Diffusor plates mounted on the burners direct the gas flow along the inner furnace wall. This produces a combination of radiant and convective heat, which has the positive effect that a high input of heat into the liquid zinc is achieved at relatively low furnace temperatures.
Throughout furnace operation, the output of the burners is infinitely adjusted to the throughput of the furnace. Thus the temperature drop in the zinc bath caused by the dipping of a new batch is minimized. Another positive feature is that the furnace always consumes just the amount of energy needed in a certain situation. This regulating mode also avoids abrupt temperature changes, which otherwise would cause strain in the galvanizing tank structure. Thanks to these features, furnaces from Körner achieve long service lives.

About Zink Körner
Zink Körner GmbH designs and manufactures the complete array of hot-dip galvanizing equipment for bulk material, tubes and pipes, miscellaneous small parts and centrifugal parts.
The supply range encompasses complete galvanizing plants, including pretreatment and handling equipment. The company provides design, engineering, manufacture, erection, commissioning and after sales service. Zink Körner maintains a worldwide network of branches and licensees.
Zink Körner has launched many pioneering developments during its company history. For example, as early as at the beginning of the 1970s the company built the first automated centrifugal galvanizing plants, which have markedly enhanced the quality of the end products and the energy efficiency of the galvanizing process. The company took another innovative move when it developed dedicated burner technology for hot-dip galvanizing applications.
Zink Körner is a company of the Körner Group, which was established in 1928. Thus the Group builds on more than 80 years of experience in industrial furnace technology and auxiliary equipment.
Within the Group, Wire Körner GmbH designs heat treatment equipment for wire and narrow strip. TVT Kordt GmbH develops plants for thermal process technology, with a focus on industrial furnaces for the heat treatment of steels, special steels and non-ferrous metals.
