Steel slitting, also known as rolled steel slitting is a manufacturing process where metals with wide coils are basically fed through a slitter lengthwise in order to be cut down into smaller and narrower coils. These coils can be made in different sizes ranging from a capacity of 8” up to 36”, so you can choose what size, width and capacity of coil that you need and the slitter will do it for you.
The process involves the metal coil to run through the upper and lower circular blades that are present in the slitter. They are more commonly referred to as knives and these blades are sharp enough to create smooth metal strips. A god setup that involves making sure that every part of the machine is set up correctly, using good quality, sharp knives and balancing the recoil, uncoil tension are all key to ensure a good job. If you have issues in the setup or in the quality of the knives being used, you will notice a few problems in your output like visible knife marks on the metal, edge burr, bad edge quality, edge waves and the width of the metal being out of the specified size/width/diameter etc.
Sometimes these problems are allocated to poor quality of the metal that was used, other times, like I mentioned above, there might be a problem with your setup or materials. In order to make sure that you get perfect results every single time, if you are working with steel coil slitting & toll-slitting, you need to make sure that you identify and know of any possible variable that can affect the process and results, and then make sure to control every one of those variables enough to get the right output every time, because if you are not taking care of things in a controlled setting, you will not get the results you want.
