Many galvanized wire diameter products are formed by wire drawing, wire drawing is a processing technology, which can make the product reach the required shape and meet the standard mechanical properties. Cold drawing is drawing at recrystallization temperature, hot drawing is drawing at crystallization temperature, and warm drawing is drawing at higher than room temperature and lower than crystallization temperature. Cold drawing is a common drawing method.
Hot drawing is the heating carried out before the metal wire enters the die hole, mainly used for drawing high melting point metal wire; Warm drawing is the drawing carried out by heating the heater to the range temperature, mainly used for drawing galvanized and difficult to deform steel wire.
The surface of the alluvium before electrogalvanized wire diameter hot dip galvanizing can remove the surface film layer, surface impurity and other shortcomings according to the basic technology to find and solve; Excessive foam is caused by soap and soapable surface active substances such as human fat brought into the tank. A moderate rate of foam production would be harmless.
The presence of many fine homogeneous particles in the tank can stabilize the foam layer and use activated carbon mat to remove surface active substances. Or make the bubble unstable according to excessive concern, which are all reasonable countermeasures; Other measures should also be adopted to reduce the amount of surfactant brought in. The introduction of organic matter can dramatically reduce the speed of electroplating process. Although the secret recipe of organic chemistry is beneficial to the high accumulation rate, the thickness of the coating cannot meet the requirements after the organic matter is brought on, so activated carbon can be used to solve the tank.
