Note Of Q345B Seamless Steel Pipe Galvanizing Method And Temperature Control
2021-11-18 10:54:48

Q345B seamless steel pipe is an important material and type of seamless steel pipe. For Q345B seamless steel pipe, it is necessary to continuously strengthen its performance and production methods and methods. During the production process of Q345B seamless steel pipe Attention should also be paid to the method of galvanizing, which makes Q345B seamless steel pipes harder, more wear-resistant and greatly improved in performance. When Q345B seamless steel pipe is galvanized, it is necessary to pay attention to the stability of the temperature. The temperature change should not be too large or too low. It should be enough. It is necessary to continuously enhance the ability of Q345B seamless steel pipe galvanizing and temperature changes. For Q345B seamless steel pipe, as long as you can pay attention to these, you can improve the quality of galvanizing, thereby improving the overall performance of Q345B seamless steel pipe.

It can be affirmed from the historical test and production practice that the temperature of the zinc solution for the hot-dip galvanizing of Q345B seamless steel pipe can be controlled at 450 ~ 460’C. When the temperature is too high, it will increase heat consumption, shorten the service life of the steel zinc pot, speed up the formation of zinc slag and zinc ash, and affect the quality of the galvanized Dendrobium silkworm plastic garden layer. When the temperature is low, it will affect the ability of Q345B seamless steel pipe to be galvanized, and because the fluidity of the zinc liquid is reduced, the zinc layer accumulation is thickened and uneven.

Experienced hot-dip galvanizing workers control the dipping time by observing the reaction of hot-dip galvanizing: "Put the Q345B seamless steel pipe into the immersion zinc liquid until the" boiling "phenomenon stops, and then immediately raise it without delay, In this way, the thickness of the zinc layer required for most applications can be obtained.
