16Mn galvanized steel pipe

16Mn of seamless steel tube hot dip galvanizing time and temperature how to control

From the traditionally test and production practice have to be sure, 16 mn of seamless steel tube hot dip galvanized zinc liquid temperature control in 450 ~ 450 'C temperature range for the best. When the temperature is high, can increase the heat loss, shorten the service life of steel zinc pot, to speed up the production of zinc dross and zinc ash, affect the quality of the galvanized welcome silkworm plastic nursery layer. When the temperature is low, can affect the ability of 16 mn seamless steel tube galvanized, and due to lower liquid zinc liquid zinc layer thickening uneven.

Experienced hot galvanizing workers is by observing the reaction of the hot galvanizing phenomenon to control hot-dip time: "dip 16 mn seamless steel tube into until" boiling "phenomenon in zinc liquid to stop, then don't delay to come up immediately, so that you can get the most use the thickness of zinc required".

Most of the research results show that a zinc alloy layer under the pure zinc layer thickness is associated with leaching time of zinc, and pure zinc layer thickness is associated with the proposed speed of 16 mn seamless steel tube. Some production for many years the pylon factory, metal structure factory, steel tube hot dip galvanized factory and auto parts factory hot dip galvanized Steel zinc leaching process time generally is 30 ~ 60 s.
