Angle steel is a common steel, and galvanized angle steel is on the basis of the angle, after the galvanized process of a product, effectively extending the life of the angle, but also more beautiful.The following galvanized angle manufacturers xiaobian for you to briefly introduce the development process of galvanized angle and some advantages of galvanized angle.
The process of galvanizing is the physical and chemical reaction of angle steel immersed in molten zinc liquid, with the outside air or other substances, forming a layer of metallic zinc on the surface, which is mainly used for metal facilities in various industries.Galvanized steel strip angle is the key equipment of hot dip galvanizing, galvanized steel angle long-term work in the conditions of high temperature oxidation and attachment, so the material is important, after years of experimental research has been achieved from complex to simple change.
The earliest galvanized angle steel factory, its galvanized angle steel is made of pig iron, the carbon content of this high silicon, poor corrosion resistance, short service life.Later developed to have steel production, the use of pure iron steel, but galvanized channel with the strength of China's low, easily deformed at high temperatures and life is very short.The use of low carbon and low silicon steel plate manufacturing pot under normal use, the service life can be increased to a year and a half to two years, this life for the steel to bring said still too low.After several tests and experience that the manufacture of zinc pot for heating 8360kj / h, but such a large area of the heat transfer surface is impossible to achieve, and therefore galvanized angle has been impossible to meet, in this case under the development of the frequency induction heating refractory ceramic pot.
Galvanized angle steel manufacturers have experienced from the beginning of coal, oil, gas to the current resistance heating, from the simple investment in small equipment, low thermal efficiency, low temperature control accuracy, large labor force, to the current investment, high heating, operating environment is good, simple, uniform heating, high temperature control accuracy, convenient maintenance and other processes.
