Steel grating hot dip galvanizing control temperature


In the hot-dip galvanizing technology, it is necessary to ablate the ingot under high temperature and then add some auxiliary chemical materials. Operating temperature is a part of hot-dip galvanizing technology, but also a very important part. Next, let's introduce the temperature control of hot-dip galvanized steel grid.


Before the galvanizing we first pickling side, so very good to control the temperature change when galvanized.


Steel grating in the galvanized time, because the temperature is not the same and holding time is not the same, its iron loss (molten iron) is not the same. At a temperature of about 450 ° C, the amount of iron loss is drastically added depending on the addition of heating and holding time. However, when the temperature is lower than or may be higher than 430-480 ℃, will follow the extension of iron loss increase will become slow, so we will 430-480 ℃ this period called malignant dissolution zone. At this moment, the zinc liquid has the most serious corrosion on the steel grating and the zinc pan. When the temperature exceeds 560 ℃, the iron loss is remarkably added. When the temperature exceeds 660 ℃, the zinc is damaging to the steel grating. , Then zinc dross will be added sharply, there is no way galvanized. Therefore, in the hot-dip galvanizing time need to control the temperature within 430-450 ℃.
