Vim li cas thiaj ua tiav cov txiaj ntsig zoo dua thaum Oscillating Steel Tubes lossis stirring cov tshuaj thaum Pickling

Thaum pickling steel hlab, cov kev paub hauv qab no feem ntau pom: Ua ntej, thaum cov hlau hlab oscillated los yog thaum cov tshuaj pickling yog agitated los ntawm chav cua sov, lub pickling ceev yog ntau npaum li cas sai dua li thaum lub steel tubes nyob ruaj ruaj nyob rau hauv lub pickling tov. Piv txwv li, thaum pickling steel hlab nyob rau hauv ib tug reciprocally txav pickling pob tawb nrog ib tug ceev ceev ntawm 30 zaug ib feeb, lub pickling ceev yuav nce li ntawm 70%; Yog hais tias cov cua kub yog siv los do cov kua qaub, lub pickling ceev ntawm steel hlab yuav nce li ntawm 20%. Qhov thib ob, raws li qhov saum npoo ntawm cov hlab ntsha steel yog scoured los ntawm cov tshuaj pickling, qhov txuas ntawm hydrogen yog txo, ua rau tsawg hydrogen diffusing rau hauv cov hlau substrate. Qhov no txo ​​qis qhov tshwm sim ntawm cov kua qaub embrittlement thiab ua kom lub zog txhua yam ntawm cov raj steel. Nyob rau tib lub sijhawm, vim cov nyhuv scouring, cov npuas npuas adhering rau saum npoo ntawm cov hlab steel thiab lwm yam impurities, hlau ntsev, thiab zeb nplai tau tev tawm, ua rau lub raj hlau huv si. Thirdly, nplawm cov tshuaj pickling tuaj yeem tswj tau qhov sib xyaw ua ke, tso cai rau kev siv ntau ntxiv ntawm cov tshuaj pickling.
