Ama-Rolling Mills angamaqhawe angaziwa ezimbonini eziningi, aguqula izinto zokusetshenziswa zibe yimikhiqizo ebalulekile. Enhliziyweni yalezi zigayo kukhona ama-rolls - amathuluzi angama-cylindrical adlala indima ebalulekile ekubunjweni kwensimbi kanye nenqubo yokubumba. Ngokwandisa ukunemba nokusebenza kahle, ama-roller aqinisekisa ukukhiqizwa okungenamthungo kwezinto ezingenakubalwa, kusukela ensimbi kuya ephepheni.

Amarola okugaya: umgogodla wokukhiqiza:

Imiqulu yezigayo zenziwa ngezinto eziqinile njengensimbi, insimbi nama-alloys. Ziza ngayo yonke imimo nosayizi, kodwa zonke zinenhloso efanayo: ukumelana nengcindezi enkulu kanye nobunzima ngenkathi iletha imiphumela enembayo nengaguquguquki. Njengephuzu eliyinhloko lokuxhumana phakathi kwensimbi nomshini wokugaya, ama-rolls angaphansi kwamandla abalulekile ngesikhathi sokugoqa.

Ikhwalithi yomqulu inqunywa izici ezihlukahlukene, okuhlanganisa ukuphela kwayo kwendawo, amandla, ukuqina, nokumelana nokugqoka kanye nokushaqeka kokushisa. Abakhiqizi bachitha isikhathi esiningi nezinsiza ekuklameni amaroli akwazi ukumelana nemishini esindayo nezimo zokusebenza ezinzima. Ukugcinwa okufanele kanye nokugaywa kabusha nakho kubalulekile ekwandiseni impilo nokusebenza kwamaroliUkunemba kwamaroli kuthinta ngqo ikhwalithi yomkhiqizo wokugcina. Ukuzuza ukujiya okungaguquki nokunciphisa ukonakala kwendawo ngokugingqika okunembayo akuqinisekisi nje kuphela ukuqina komkhiqizo, kodwa futhi kuthuthukisa ubuhle bomkhiqizo. Ngokuzungezisa ngakunye, irola idlulisela ukuthungwa kwayo kwendawo nezinye izici ezifiselekayo ensimbi, iyilolonge ngokunembile emibhalweni yekhasimende.

Nakuba igama elithi “roller” nelithi “tumbler” evame ukusetshenziswa ngokufanayo, kubalulekile ukuhlukanisa phakathi kwalokhu okubili. Njengoba kushiwo ngenhla, ama-rolls abhekisela kumathuluzi angama-cylindrical afakwe ezigayweni eziginqikayo. Amarola, ngakolunye uhlangothi, ngokuvamile amelela amathuluzi asizayo asiza ekuphatheni izinto ngaphakathi komshini wokugaywa. Igayidi yama-roller, isekelo noma impahla yokuthutha ngesikhathi sokugingqa, iqinisekisa ukuthi ihambisana kahle nama-roller.

Amaroli omshini wokugaywa awazona nje izingxenye eziwumshini; Ziwukhiye ekuletheni izinqubo zokukhiqiza ezinembayo, ezisebenza kahle. Lawa mathuluzi abalulekile akhiwe futhi agcinwe ukuze amelane namandla amakhulu kuyilapho enikeza ukunemba nokuvumelana ukuze alolonge izinto ezihlukahlukene. Ukuqonda indima ebalulekile yama-roller nokusebenzisana kwawo nama-roller kubalulekile ekwandiseni ukusebenza kwefekthri nokuqinisekisa umkhiqizo wokugcina wekhwalithi ephezulu. Intuthuko eqhubekayo kubuchwepheshe be-roll ithembisa ukuvula ubukhulu obusha bokusebenza kahle nokunemba, ukuqhubekisela phambili izimboni zibe ikusasa elichazwe izinqubo zokukhiqiza ezisebenza kahle kakhulu.
