Hot-rolled angle steel

Hot-rolled angle steel is the name of a technique for making angle steel. In contrast to hot-rolled angle steel, there is also a type called cold-rolled angle steel. Both hot-rolled angle steel and cold-rolled angle steel have their own advantages and disadvantages. Angle steel is a kind of product that is often used in construction and industry. There is a large amount of inventory in the market. The market competition of angle steel products is relatively benign, so the price difference of angle steel is not big.steel sheet supplier

What is hot rolling? Hot rolling is relative to cold rolling, which is rolling below the recrystallization temperature, and hot rolling is rolling at a temperature above the recrystallization temperature.

Introduction to the advantages and disadvantages of hot rolled angle steel:

Hot-rolled angle steel

Advantages: It can destroy the cast structure of the ingot, refine the grain of the steel, and eliminate the defects of the microstructure, so that the steel structure is compacted and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the steel is no longer isotropic to a certain extent; bubbles, cracks and looseness formed during casting can also be welded under high temperature and pressure.

Disadvantages: 1. After hot rolling, non-metallic inclusions (mainly sulfides and oxides, as well as silicates) inside the steel are pressed into thin sheets, and delamination (sandwich) occurs. The delamination greatly deteriorates the tensile properties of the steel in the thickness direction, and it is possible to cause interlayer tearing when the weld is shrunk. The local strain induced by weld shrinkage often reaches several times the yield point strain, which is much larger than the strain caused by the load;

2.Residual stress caused by uneven cooling. The residual stress is the internal self-phase equilibrium stress without external force. The hot-rolled steel of various sections has such residual stress. The larger the section size of the general steel, the larger the residual stress. Although the residual stress is self-phase-balanced, it still has some influence on the performance of steel members under external force. Such as deformation, stability, fatigue and other aspects may have adverse effects.

Specifications of hot-rolled angle steel: The width of the steel plate can also be any size of 50mm or 10mm. The length of the steel plate is 100mm or 50mm, but the minimum length of the steel plate with thickness less than or equal to 4mm is not less than 1.2m, and the thickness of steel plate is less than 4mm. The length must not be less than 2m. Steel plates with a thickness of less than 30 mm may have a thickness interval of 0.5 mm as required.galvannealed steel sheet suppliers

The above small and medium series not only introduced to you, what kind of technology is hot rolling, what is angle steel, and what are the advantages and disadvantages of hot rolled angle steel, but also introduces the specifications of hot rolled angle steel. . The advantages of hot-rolled angle steel are relatively high. At the time of hot rolling, the structural structure of the angle steel will be changed, and the forming effect of the angle steel at high temperature will be better. The use of hot-rolled angle steel will make the quality of the building more Good, but the process of hot-rolled angle steel is more complicated, so the output of hot-rolled angle steel is relatively low.

Main process characteristics of the spiral steel pipe

The spiral tube is a spiral steel tube, which is made of steel reel as a raw material, is often heated and extruded, and is welded by an automatic double-wire double-sided submerged arc welding process. The spiral steel pipe feeds the strip into the welded pipe unit spiral steel pipe supplier. After multi-roll rolling, the strip is gradually rolled up to form a circular tube blank with an open gap.
