From the historical test and production practices can be sure, 16mn seamless steel pipe hot-dip galvanized zinc liquid temperature to control the optimum temperature in the range of 450 ℃ ~ 460 ℃. When the temperature is high, heat consumption will increase, shortening the life of steel zinc pot, speed dross and zinc ash generation, affecting the quality of galvanized Gok silkworm nursery plastic layer. When the temperature is low, it will affect the capacity of 16mn seamless galvanized and zinc was due to reduced liquidity of the zinc layer stacked thick uneven.
Experienced workers are galvanized by observing the response to the phenomenon of hot-dip galvanizing dip to control the time: the 16mn seamless steel pipe into the zincate solution until the “boiling” phenomenon stops, then do not delay to put forward immediately, so you can get zinc layer thickness required for most applications
Most studies show that the pure zinc layer under the zinc-iron alloy layer thickness and zinc coating, whereas the thickness of the layer of pure zinc and asked about the speed 16mn seamless steel pipe. Some of the production plant for many years pylons, metal structure factory, steel hot-dip galvanizing plant and auto parts hot dip galvanizing plant zinc processing time is generally 30s ~ 60s.
