As a widely used stainless steel profile, the quality issue of channel steel is a common concern for both manufacturers and customers. Cutting and storage can affect the quality of the channel steel, so it is important to pay attention to the stress on the legs during cutting to avoid tearing. In addition, it is also very important to store channel steel in a standardized manner, meeting the requirements of different types and specifications to ensure that the channel steel will not be corroded or deformed.
The same type of materials should be stacked separately according to the order of storage, in order to facilitate the implementation of the principle of first in, first out. Moreover, the stacking principle requires that under stable and safe stacking conditions, materials of different varieties should be stacked separately to prevent confusion and mutual corrosion. Stacking height. It is prohibited to store items that have corrosive effects on steel near the stacking position, and the bottom of the stacking should be raised, sturdy, and flat to prevent moisture or deformation of the materials.
The slope of the legs of the upper and lower shear blades is basically the same as the hole shape of the finished channel steel. When cutting, attention should be paid to the basic simultaneous force on the legs. The shear force is high, and the shear blade wears quickly. On the one hand, the shear indentation at the leg end is severe, and on the other hand, after the shear blade ages, it is easy to see tearing and more burrs in the shear part of the channel steel. Compared to other parts, the two shoulders of the channel steel are relatively thick and require a greater shear force, resulting in faster wear of the shear blades.
Compared to the waist, the two legs of the channel steel are affected by the shear angle. When the shear blade is worn, the amount of shear decreases when cutting the two legs. The leg shear changes from normal cutting to tearing, and the end face of the channel steel leg is prone to burrs.
The above are the precautions for cutting and storing channel steel. Each manufacturer or merchant must follow the above requirements to ensure that the channel steel can be applied to production.
