Angle steel is widely used in the construction industry and is an excellent building material. It is loved by the construction industry for its good toughness. But sometimes we will find some problems in the use of Jinan angle steel, such as billet grinding, slide scratch, furnace bottom rolling pit, etc., these problems will greatly reduce the use performance of angle steel, so how can we avoid it?
1. Blank grinding. When the angle steel billet is polished with coarse sand wheel, there will be wear marks on the surface of the rolled medium plate, especially for the thick plate above 20 mm.
2. Scratch on the slide. In the heating furnace, when the billet moves along the slide way, it is easy to scratch the lower surface of the billet.
3. Rolling pits. During alignment, the friction between the center plate and the middle plate edge causes the edge burr to splash on the surface of the medium plate, forming the surface rolling crater.
4. Large chain scratch. The falling off between the chains causes the steel plate to move asynchronously on the cooling bed and forms the scratch on the lower surface.
5. Furnace bottom roller pressing pit. Under the action of high temperature gas and load, the bottom roller is easy to form surface accretion, resulting in pit under the middle plate.
6. Press pit of straightener. In the process of straightening, oxide scale is easy to form on the surface of carbon steel.
7. Scratch during lifting. It is easy to cause edge rib damage when lifting steel plate, and scratch on steel plate surface caused by nonstandard operation during unloading.
When using angle steel in construction enterprises, it must be carried out in strict accordance with the requirements of the specification, so as to give full play to the use value of angle steel. In order to improve the performance of angle steel, the manufacturer also needs to strictly control the production quality when designing and processing to ensure that the angle steel processed meets the factory requirements and can be widely used in actual production. Jinan angle steel, channel steel and I-beam products are affordable and complete in specifications. Welcome to inquire.
