Nto ua cov raj seamless (smls) feem ntau suav nrog: steel tube nto tua peening, zuag qhia tag nrho nto sib tsoo thiab txhua yam ua. Nws lub hom phiaj yog txhawm rau txhim kho qhov zoo ntawm qhov chaw lossis qhov tseeb ntawm cov raj steel.

Txhaj tshuaj peening rau saum npoo ntawm seamless raj: Txhaj peening rau saum npoo ntawm cov yeeb nkab steel yog txau hlau txhaj tshuaj los yog quartz xuab zeb txhaj tshuaj (suav hu ua xuab zeb txhaj) ntawm ib tug tej yam me me rau ntawm qhov chaw ntawm seamless raj ntawm ib tug kub ceev mus khob tawm ntawm oxide nplai rau ntawm qhov chaw kom txhim kho qhov smoothness ntawm steel raj nto. Thaum cov hlau oxide nplai nyob rau saum npoo ntawm lub raj steel yog crushed thiab tev tawm, qee qhov chaw tsis xws luag uas tsis yooj yim pom los ntawm qhov muag liab qab yuav raug nthuav tawm thiab yooj yim tshem tawm.

Qhov loj thiab hardness ntawm cov xuab zeb txhaj tshuaj thiab txhaj tshuaj ceev yog qhov tseem ceeb cuam tshuam rau kev txhaj tshuaj peening zoo ntawm steel raj nto. Yog tias cov xuab zeb txhaj tshuaj loj dhau lawm, lub hardness siab dhau lawm thiab kev txhaj tshuaj nrawm dhau, nws yooj yim rau crush thiab poob tawm ntawm cov nplais oxide rau ntawm cov yeeb nkab steel, tab sis nws kuj tseem tuaj yeem ua rau ntau qhov pits. ntawm ntau qhov sib txawv ntawm qhov chaw ntawm lub raj steel los tsim pockmarks. Ntawm qhov tsis sib xws, cov hlau oxide nplai yuav tsis raug tshem tawm tag nrho. Tsis tas li ntawd, lub thickness thiab ntom ntawm oxide nplai ntawm cov hlau raj nto kuj tseem cuam tshuam rau kev txhaj tshuaj peening nyhuv.
Lub thicker thiab denser cov hlau oxide nplai ntawm cov hlau raj nto, qhov phem ntawm cov hlau oxide nplai tu nyob rau hauv tib yam mob. Txau (steev) tua derusting yog txoj hauv kev zoo tshaj plaws rau kev tshem tawm cov kav dej.

Zuag qhia tag nrho kev sib tsoo ntawm qhov chaw ntawm seamless raj: Cov cuab yeej rau kev sib tsoo tag nrho ntawm sab nrauv ntawm cov yeeb nkab steel feem ntau suav nrog abrasive siv, sib tsoo lub log thiab cov tshuab sib tsoo. Tag nrho kev sib tsoo ntawm sab hauv ntawm cov yeeb nkab steel txais kev sib tsoo log sib tsoo los yog sab hauv mesh sib tsoo tshuab sib tsoo. Tom qab qhov saum npoo ntawm lub raj steel yog hauv av tag nrho, nws tuaj yeem tsis tsuas yog tshem tawm cov nplais oxide ntawm lub raj steel, txhim kho qhov chaw tiav ntawm lub raj steel, tab sis kuj tshem tawm qee qhov me me ntawm qhov chaw. steel tube, xws li cov kab nrib pleb me me, cov kab plaub hau, qhov pits, khawb, thiab lwm yam. Kev sib tsoo ntawm qhov chaw ntawm lub raj steel nrog txoj siv abrasive lossis kev sib tsoo lub log tag nrho yuav ua rau muaj qhov tsis zoo feem ntau: cov tawv nqaij dub ntawm cov yeeb nkab steel, ntau phab ntsa thickness, dav hlau (polygon), lub qhov dej, kub hnyiab thiab hnav cov cim, thiab lwm yam. Cov tawv nqaij dub ntawm qhov chaw ntawm lub raj steel yog vim muaj qhov me me ntawm kev sib tsoo los yog pits ntawm qhov chaw ntawm lub raj steel. Kev sib tsoo ntau ntxiv tuaj yeem tshem tawm cov tawv nqaij dub ntawm qhov chaw ntawm lub raj steel.

Feem ntau hais lus, qhov zoo ntawm cov yeeb nkab steel yuav zoo dua, tab sis qhov kev ua tau zoo yuav qis dua yog tias lub seamless steel raj yog hauv av nrog txoj siv abrasive tag nrho.
