Introduction
Cold-formed unequal slot steel (GB 6723-86) is a type of steel commonly used in construction and other structural applications. It is manufactured through a process of reheating and subsequent cooling in which the steel is heated, then cooled so that a uniform grain structure is achieved. The resulting steel has a higher yield strength that can be utilized in many different applications.
Description
Cold-formed unequal slot steel (GB 6723-86) is characterized by its unequal slot shape which allows for rigid connections between two parts of the structure. It has a higher yield strength than hot-formed steel and is also known as cold-rolled steel. The unequal slot shape of cold formed unequal slot steel allows for increased surface area exposed to the air, thus increasing its economic value. Cold formed unequal slot steel is often used in the manufacture of sheet metal and provides better corrosion resistance due to its higher strength. This type of steel is used in applications such as automotive components, piping, and roofing.
Manufacturing Process
Cold-formed unequal slot steel (GB 6723-86) is typically manufactured via hot rolling, which involves heating the steel to temperatures above its recrystallization temperature and then allowing it to cool to obtain its desired internal grain structure. This process creates a steel with a higher yield strength, higher resistance to oxidation, and a smoother surface. This makes it ideal for many structural applications.
Applications
Cold-formed unequal slot steel (GB 6723-86) is commonly used in the form of sheet metal for applications such as roofing and piping. It is also used for automotive components, construction projects, and even for the manufacture of electronics. Its higher yield strength makes it ideal for these applications as it is more durable and resistant to corrosion.
Conclusion
Cold-formed unequal slot steel (GB 6723-86) is a type of steel used in many applications due to its higher yield strength, smooth surface, and corrosion resistance. It is typically manufactured via a hot rolling process that gives it its desired grain structure and properties. This type of steel is commonly used in automotive components, construction projects, and other structural applications.
