Inconsutilem ferro pipe frigus processus modi:
①Cold Rolling ②Cold Drawing ③sspinning
A. Frigus volvens et frigus drawing sunt maxime propter: praecisione, tenuis-muralis, parva diametro, abnormal crucem-section et summus vires Pipes
b. Spinning is mainly used for: the production of large diameter, thin wall or super large diameter, ultra-thin wall steel pipes, and has a tendency to be replaced by welded pipes (steel strip, welding, heat treatment, etc.)
Pelagus processus fluxus producendo seamless ferro fistularum per frigus drawing:
Pipulam blank praeparatione → frigus drawing ferro pipe → finiens et dispensando Finitum ferro pipe → inspectionem
Characteres in seamless ferro fistulae produci per frigus drawing (comparari calidum volubilem)
①the exterius diameter ferro fiat minor donec capillaribus tubis potest produci
②sterel pipe murum est tenuior
③sterel pipe habet altiorem dimensional accurate et melior superficies qualis
④the crucis-sectional figura de ferro pipe est magis universa, et variabilis crucem-section et speciale informibus ferro fistulae potest produci
⑤ ferro pipe perficientur est superior
⑥high productio sumptus, magna instrumentum et fingunt consummatio, humilis cede rate, parva output et altius environmental praesidium requisitis
Frigus ducta fistulam qualitas defectus et ne
⒈ qualis defectus frigoris, instructa ferro fistulae maxime includit: inaequalis murus crassitudine ferro fistularum, ex-of tolerantia exterius diameter, superficiem rimas, superficiem lineae et exasperat, etc.
①STHA inaequales murum crassitudine frigoris, instructa ferro fistularum ad murum crassitudine accurate tubo fistulam blank, hausit modum, tractus centerline offset, foramen figura, deformatio processus parametri et lubricatae condiciones.
A. Improving murum crassitiem accurate tubi blank est momenti requiritur ad meliorem murum crassitudine accurate frigus ferro tibia.
b. Pelagus ad extubation sine mandrel est ad redigendum diameter et deformatio
c. Foraminis figura est momenti factor afficiens inaequaliter murum crassitudine frigus trahi ferro fistularum.
d. Est etiam efficax modum ad curare in pickling qualis est fistulam blank, removere ferrum cadmiae scale super eius superficiem et amplio lubricatae qualitas.
②during productio processus magna operam solvit ad gerunt et lacrimam aptius et drafting
③in ad redigendum rimas superficies ferro pipe post trahendum, qualified pipe codicellos electus et superficiem defectibus pipe codicellos esse terram. When pickling the pipe blanks, it is necessary to prevent over-pickling to avoid pitting or hydrogen embrittlement, and to To prevent under-pickling and incomplete cleaning of the oxide scale, ensure the annealing quality of the tube blank during use, adopt a reasonable tube drawing method, select appropriate deformation process parameters and tool shape, and strengthen the adjustment and inspection of the drawing center line.
④improving et pickling qualis et lubricatae qualis pipe blank, cursus tool duritiem, uniformitatem et superficiem metam mos succurro reducere ad eventum rectae lineae et scalpit in ferro pipe.
