Cold rolled tube outer surface greasy dirt rotates scavenge unit online
Technical field
The utility model relates to a kind of cold rolled tube outer surface decontamination treating apparatus, particularly relates to a kind of scavenge unit of online removal cold rolled tube outer surface grease.
Background technology
Cold rolling grease must be used in the cold-rolled process of seamless steel pipe, can guarantee cold rollingly to carry out smoothly, the quality of cold rolled tube can be ensured again, therefore cold rolling grease is all attached with at the outer surface of cold rolled tube and steel tube inner hole surface, seamless steel pipe be cold-rolled to final size after thoroughly must remove and be attached to the outer surface of cold rolled tube and the cold rolling grease of bore area, otherwise product is just defective, cannot meet user's requirement.
After Steel Pipe Cold terminates, surfaces externally and internally all adheres to stronger formation rolling greasy dirt, traditional deoiling method is all undesirable, such as adopt traditional strong acid, highly basic ablution, chemical reagent (poisonous trichloro-ethylene) ablution, or carry out hot removal operation method with steam, carry out removal operation with high pressure emission bullet head dummy oil removing instrument and dry etc. again after adopting immersion.At present, the sweep-out method generally adopted is by cleaning fluid heated wash method, cold rolling good steel pipe is left concentratedly, then quantitatively the rinse bath being marked with chemical cleaning solution is put in handling, by heating, electrochemical deoiling agent absorbed grease or react, finally will remove and be adsorbed on grease and impurity on steel pipe.
This deoiling method technological requirement is very high, slightly do not note just causing cold rolled tube tube surfaces oil stain removing unclean, in follow-up heat treatment process, remaining grease will make tube wall produce carbonization under the high temperature conditions, carburizing is caused to tube surfaces, thus causes more serious surface quality problems, in the actual use procedure of tubing, pitting corrosion ability and stress corrosion ability decline greatly, shorten tubing service life.This deoiling method not only production efficiency is low, and deoiling effect is unstable, cannot realize online removing, and production technology falls behind, and production cost is high.Adopt a large amount of cleaning fluid to clean, not only waste raw material, and its deoiling effect is general, cannot clean out especially, directly affect steel duct quality for its inwall greasy dirt of small-bore, longer steel pipe.Adopt vapour degreasing technique and high pressure emission bullet head oil removing process, need steam and high pressure emitter, cost is higher.Adopt the method for soaking oil removing, need special oil removing place, floor space is large, and operation inconvenience.The oil removing of existing cold rolled tube outer surface, operating personnel carry out wiping after rinsing with cleaning agent again, and in order to wiped clean, operating personnel understand wiping multipass, and the wiping process time is long, and labour intensity is large, and cost is high.
