Japan NKK Successfully Developed Laminated Plates for Stainless Steel and Steel Plate Cans

NKK Co., Ltd. (NKK) actively develops and expands the production of high value-added steel, and has recently achieved two major achievements. The self-developed stainless steel clad steel plate was favored by Saudi Arabian oil companies. It signed a 1,000-ton supply contract with another plastic film. The steel plate was closely attached to the can-making laminating board, effectively simplifying the manufacturing process for food and pharmaceutical large-scale tanks. The current monthly production capacity is 1,000 tons, and it will increase to 8,000 tons in 2005.
Reversing the unfavorable situation of the weakening steel market and declining corporate profits, NKK actively develops and expands the production of special steel grades with high added value to meet the needs of users while expanding the market and improving the efficiency of enterprises. The self-developed rare species, stainless steel combined steel plates, are made by pressing together steel plates of two different types of steel and utilizing the different properties of the steel plates on both sides.
The steel grade favored by the Saudi Arabian Oil Company a few days ago was the combination of stainless steel and low-carbon steel. The number of supply contracts was more than 1,000 tons and the transaction amount was about 200 million yen because the steel plate only uses stainless steel on the easily corroded side. Therefore, the cost is significantly lower than that of all stainless steels.
Another successfully developed can-making laminating board attaches the plastic film tightly to the steel sheet, which facilitates the simplification of the manufacturing process of large-size cans. With the development of the food industry and the pharmaceutical industry, the demand for large-sized cans grows rapidly, and the demand for laminates will also increase. With a monthly production capacity of only 1,000 tons, NKK laminates will expand its capacity in the next 2-3 years, aiming to achieve a production capacity of 8,000 tons in the month of 2005.
NKK's newly developed can-making laminating board has now received 18L cans from companies specializing in the manufacture of 18L cans to improve corrosion resistance. Most of them are on the surface, but organic solvents increase the company's environmental protection costs. NKK applies the plastic film directly on the steel plate at the request of the user. However, the production efficiency is low and the quality is poor. Therefore, the continuous heating of the unwinding of the steel plate is changed, and the plastic film is then rolled into a roll to ensure the product quality.
