Angle steel is a common steel, and galvanized angle steel is a product that has been treated by galvanizing on the basis of angle steel, which effectively extends the service life of angle steel and is also more beautiful. The following galvanized angle steel manufacturers Xiaobian for you to briefly introduce the development of galvanized angle steel and some advantages of galvanized angle steel.
The galvanizing process of galvanized angle steel manufacturers is a process of immersing angle steel in molten zinc liquid, physicochemical reaction with outside air or other substances, forming a layer of metal zinc on the surface, mainly used in various industries. Above the metal facilities. Galvanized angle steel is the key equipment for hot-dip galvanizing of steel strip. The galvanized angle steel is under high temperature oxidation and medium condition for a long time, so the material is not important. After years of experimental research, it has realized the transition from complex to simple.
The earliest galvanized angle steel manufacturers, whose galvanized angle steel is made of pig iron, have high carbon content, poor corrosion resistance and short service life. Later, it was developed to have a steel plate and a pure iron plate. However, the galvanized channel steel has a low strength in China, is easily deformed at high temperatures, and has a short service life. Under the normal use of a low-carbon, low-silicon steel plate, the service life can be increased to one and a half to two years, and this life is still too low for the steel strip. After many trials and experience, it is known that the heat supply for manufacturing zinc pots is 8360kj/h, but such a large-area heat transfer surface is impossible to achieve, so galvanized angle steel is impossible to meet, in this case A ceramic pot of refractory material with power frequency induction heating was developed.
The galvanized angle steel manufacturers have experienced the initial combustion of coal, fuel and gas to the current resistance heating. The simple investment from the equipment is small, the thermal efficiency is low, the temperature control precision is low, the labor force is large, the investment is large now, the heating is high, and the operating environment is good. Simple, uniform heating, high temperature control accuracy, convenient maintenance and other processes.
