04 Tháng 12, 2023

Stainless steel also known as inox is a form of iron alloy containing a minimum of 10.5% chromium that was invented in 1913 by an English scientist Harry Brearley. Since then, world consumption of stainless steel has been increasing. That is the growth in demand for construction and industrial projects - where stainless steel is used for decoration and rust prevention, requires low maintenance and is an alloy steel with durability and ductility. tough,  less discolored and very good at resisting corrosion in harsh environments with the addition of different concentrations of Chromium, Nickel, Molipdenum. Many other industries are accepting stainless steel for the above reasons as well as it does not have many  requirements for product treatment and coating when used.

According to the Party and State's orientation, our country must have an advanced industry to modernize agriculture and all aspects of social life, and face the increasing demand for stainless steel in the Vietnamese market every year. development, from the end of 2009 to the beginning of 2010, Hoa Binh Inox Company decided to invest in a 1300mm wide stainless steel cold rolling line. The heart of the cold rolling factory is a 20-axis Sendzimir rolling machine upgraded by the company. I2S company from the USA belongs to the TENOVA-Italia group, a system integrator, the leading manufacturer of industrial machinery equipment for rolling mills in the world. Sendzimir's name sounds strange, but did you know it was developed? invented in the 40s of the 20th century by a Polish inventor - Dr. Tadeusz Sendzimir.

And since then, there have been just over 400 rolling machines produced and operating in 40 countries worldwide. The technology continues to be improved and inherited by this doctor's descendants. Rolling machine 20 axis whose main part is the monoblock server body, including 20 axes operating in groups, the ability to disintegrate forces makes the reaction force when the machine operates on the server body minimized, thus making The machine frame structure is durable and stable over time, while reducing the weight of the entire machine frame. The small working shaft structure makes the Sendzimir rolling mill capable of rolling very hard materials, especially stainless steel. rust with a thickness down to the micron unit, at the same time giving the plate surface quality a flat, mirror-like shine, resisting the oxidizing effects of the external environment and being sustainable over time when combined with a machine. SkinPass lamination and BA furnace technology from developed countries such as Europe and Japan.
