The Norgalv plant designed by Austrian and German experts at Koerner KVK will be a semi-automated single-line hot-dip galvanizing plant. Here, the first Koerner KVK pretreatment tank was delivered from Austria.
In August, a new galvanizing plant was built in North Bay, Ontario, which was a milestone in the plant’s 35,000 square foot pouring project. Concrete floor. Despite the delays caused by the COVID-19 pandemic, the plant should be put into operation by the end of this year. The Norgalv Ltd. plant’s goal is to meet the galvanizing demand in northern Ontario and beyond, and it is expected to employ approximately 45 employees in North Bay.
Norgalv was founded by shareholders of a group of galvanizing plants in South Africa, who studied opportunities for global expansion.
“We have strong support from the Canadian federal and provincial governments,” said Norgalv managing director Andre van Soelen (Andre van Soelen). “In choosing city-specific locations, North Bay is ahead of everyone else’s street in accommodating and helping to achieve this goal.”
Norvanv’s goal is to serve the mining supply and service industries in northern Ontario, although van Soelen believes that the quality of the company’s products and processes will attract more customers and create manufacturing opportunities in and around North Bay itself.
Van Soelen said: “There is no other galvanizing plant in northern Ontario, so some products (such as scaffolding) are not produced locally.” “If you have to ship it to the south for processing, then make it here. The products are not worth it. Now Norgalv is here, manufacturers can expand their business options here, and may want to ship finished products to the country and other regions.” Van Soelen pointed out that many other areas also require hot-dip galvanizing , Including telecommunications, road infrastructure, agriculture, oil and power generation.
Both Norgalv and North Bay see opportunities for more industrial development in the region. The company benefited from the city’s first industrial incentive program, the Airport Community Improvement Program (ACIP). ACIP provides the following incentives: municipal fee rebate program, tax assistance program (three-year rebate), and landfill tip reduction. The ACIP program has ended, but the incentive program has helped support 8 new construction projects and 1 business expansion. Building on the success of the plan, the city recently passed a city-wide alternative plan that extends industrial incentives from ACIP to appropriate properties throughout the community. The value of the savings for Norgalv from this procedure is approximately US$700,000.
The project represents an investment of US$21 million and has also received support from the federal and provincial governments. The federal government contributed US$1.5 million through FedNor, and the province contributed US$5 million.
The Norgalv plant, designed by experts from Austria and Germany at Koerner KvK, will be a semi-automated single-line hot-dip galvanizing plant equipped with an 8 x 1.4 x 3.5 m “kettle” and all other required auxiliary equipment.
Despite the delays caused by the influenza pandemic, the facility should be put into use before the end of the year. This is a view of the dryer and scrubber system during construction.
The company’s management has been keen to tout the advanced, environmentally friendly features of the technology used, which, according to van Soelen, exceeds strict European emission requirements.
“In the new galvanizing plant, we installed all the most advanced equipment,” said Manfred Schell, Koerner KvK’s sales director. “The complete pretreatment process is closed, so the acid fumes will not escape into the environment. At the same time, the acid fumes are continuously washed in the scrubber to meet the most stringent regulations. In addition, the zinc pot itself is closed, and the galvanizing process The so-called “white smoke” produced in the ash is collected and filtered in the zinc dust filter.”
All floors in the area where the company handles acids are treated with an acid-proof coating to eliminate the risk of these acids entering the ground.
The key to high-level facility safety regulations is to restrict personnel and product contact during the process.
After the lifting platform is manually filled with materials, the jig containing the galvanized material is moved to the manual shuttle in front of the pretreatment area with a manual overhead crane. After the shuttle, the material is manually driven to the pretreatment station.
At the pretreatment station, the operator starts the automated process. The operator assigns a recipe (defines the processing sequence including the immersion time and the immersion program), and then automatically involves the parts in the pretreatment process. After the pickling process starts, no treatment will be carried out.
At the end of the enclosed pickling zone, the crane automatically places the clamps on the chain conveyor in the dryer. Then, the chain conveyor in the dryer transfers the clamps from the pretreatment area to the furnace area in the dryer.
At the last position of the chain conveyor in the dryer, a crane removes the clamp from the chain conveyor and moves it to the zinc tank.
The galvanizing process itself is manually controlled. After galvanizing, the crane moves the galvanized steel to the buffer zone. Buffering and unbinding is a manual process.
The facility occupies 35,000 square feet. A perspective view of the building shows the acid delivery inlet before the exterior walls are completed.
The automatic treatment of the pickling zone can ensure a continuous work flow, and can improve the efficiency of the equipment compared with older galvanizing equipment. It can also ensure that the final product has a more reliable consistency.
In addition, the complete closure of the pickling area means that it contains acid fumes and no one is unnecessarily exposed. All flue gas in the pickling zone and zinc pot is carefully filtered to ensure that it will not be released into or outside the equipment.
At the same time, the automated crane area is enclosed by walls so that workers will not be in danger of being injured by moving materials.
Norgalv not only protects employees, but also protects the environment. This is a completely chromium-free passivation product that will produce high-quality finishes in all galvanizing work. Hexavalent chromium has been proven time and time again to be a dangerous and persistent environmental pollutant, highly toxic and carcinogenic.
TIB Chemicals AG from Germany will provide TIB Finish Polycoat for Norgalv. TIB hot-dip galvanizing technology consultant Andrew Bennison said: “The toxic hexavalent chromium has been replaced by non-toxic zirconium, which is the most corrosion-resistant metal on the planet. This is the same as the one found in children’s glue PVA. Together with the same polymer, it can provide temporary protection for the environment and prevent white rust and corrosion.”
van Soelen said: “Norgalv will strictly abide by the ASTM A123 hot-dip galvanizing standard to ensure the optimal thickness level of the zinc coating to obtain a high-quality surface quality.” “More importantly, Norgalv is establishing a type in its operations. Culture, truly respect the steel products that customers send to us. Before and after galvanizing, we will carefully check all products received to ensure that the final product not only meets the technical standards, but also reflects and enhances the manufacturer’s investment in this product Maintenance and craftsmanship.”
Van Soelen (van Soelen) said that Norgalv (Norgalv) has carried out a lot of business in the local area, but he also believes that the North Bay manufacturers have opportunities for further development.
He said: “We can create a more diversified economy here.” “I think that as more and more people understand the benefits of living in a smaller community and gain the convenience of infrastructure, these infrastructures Allowing them to sell products across the country and other regions will make recruitment in the northern region easier.”
Many processes will be automated, such as an automated trolley production line that installs the foundation.
From this perspective, we see the filter base (front) of the kettle and dust chamber, the pretreatment area and the dryer (rear).
