introduction：1、Hot dip galvanizing is developed from the older hot plating method，Ever since1836France has applied hot dip galvanizing to industry since，Its a hundred and forty years old。however，Hot dip galvanizing industry has been developed on a large scale in the past 30 years with the rapid development of cold rolled strip steel。 The production process of hot galvanized sheet mainly includes：Raw board preparation→Pretreatment before plating→Hot dipping→Post-plating treatment→Finished product inspection。According to the custom is often based on the pretreatment method of plating Different hot-dip galvanizing processes are divided into two categories: off-line annealing and in-line annealing，namely： Wet process （Hot dip galvanizing of single sheet steel） Off-line annealing single

introduction：Defects caused by improper heating 1.Coarse grain size Ferritic stainless steel has no isomeric transition，Grain growth tends to be large when heated。And the grain size is too large，It will cause greater brittleness，Reduce the impact toughness of steel。therefore，The heating temperature should not be too high，The stay time under high temperature should not be too long。 2.δFerrite increase Austenitic duplex and martensitic steels are heated to excessively high temperatures，There will be too muchδferrite，The process plasticity of the alloy is reduced，Resulting in forging cracking。1Cr12Ni2W2MoVThe heating temperature of the steel is too high due to forging，δForging cracking caused by large amount of phase precipitation。 3.
