Modern ígwè mpempe akwụkwọ: ochie nakwa n'oge a

Ka anya dị ka ndị mmadụ mụtara smelt metal na-emepụta na ngwaahịa na ya, anyị nwere ike ịghọta na ọ bara uru Njirimara nke ígwè (ike, anwụ ngwa ngwa, na-eyi ndị na-eguzogide). Ịmepụta mbụ ha masterpieces, uzú nnọọ mkpa maka mkpa mpempe akwụkwọ metal. Na-adọkpụ hama na-flaked na metal workpiece, mbịne ha tin, na ọ bụ nke mbụ ígwè mpempe akwụkwọ. The usoro bụ ogologo na-agwụ ha ike.

Ọganihu anaghị guzo, ma n'ihi na nke mkpa ígwè chọrọ ihe na ọzọ, ọ na-emepụta ihe kwesịrị ekwesị na ngwá na nke Ibé akwụkwọ na-ibido esorowo, na mgbe e mesịrị malitere tụgharịa na Rolling mills. The mbụ laminated Ibé akwụkwọ nwere a kacha nta ọkpụrụkpụ nke 0,8 mm na akụkụ 710 mm na 1420 mm na-arụ ọrụ na ha nwere nnọọ ike n'ihi na ha na nnukwu size na obere ọkpụrụkpụ. N'ihi na nke nta nke nta Switched inyefe mpempe akwụkwọ size nke 1000 mm ka 2000 mm na 0,6 mm, na n'ihu - 1250 mm site 2500 mm na a ọkpụrụkpụ nke 0,5 mm, oge a na igwe ekwe akpọrepu mpempe akwụkwọ nke 0,25 mm oké na-akparaghị ókè ogologo.

Na ihe niile ga-adị mma, ma metal na-maara na-susceptible ka ọxịdashọn (nchara), ibido nwere ike na-eche nke ihe ọ bụla, ọ bụ naanị mara mma, ma nke nta nke nta ndị mmadụ mụtara ekpuchi metal zinc.

Ná mmalite, nchara mpempe akwụkwọ na-kpochara, ndị na nkume igwe nri ọnụ ọgụgụ a na-ewepụ ya site na acid etching. Mgbe ahụ na-ekpo ọkụ akpọrepu warara na-enye ya na-Njirimara, anụ ahụ na chemical, bụ annealed. N'ihi ya, ọ bụghị naanị ike esichara ígwè mpempe akwụkwọ, ọ bụ omume na-eme ka ígwè na ngwaahịa: ọjà, warara na ndị ọzọ. Usoro ọ nwere ike rụrụ iji ụzọ dị iche iche, ha na-dabere na ụdị ngwaahịa. E nwere ụzọ nke na-ekpo ọkụ itinye galvanizing, electrolytic galvanizing na termodiffuznoe.

Na usoro nke ọkụ-itinye galvanized ígwè mpempe akwụkwọ na-mikpuru na wụrụ awụ zinc, nke bụ ofu mkpuchi ọkpụrụkpụ, n'ihi na a galvanized ígwè mpempe akwụkwọ. Termodiffuzny usoro a na-eji maka ngwaahịa na-enwe a mgbagwoju udi, maka atụ ihe dị ka mma. Mgbe galvanizing, zinc contours nke ngwaahịa. Na electrolytic usoro, itinye galvanized mkpuchi oyi akwa na-ewe ebe site electrically conductive rollers. Ụfọdụ ọrụ na-akpọ ya cathode n'aka. Mgbe ọ na-na-boro ebubo na a ígwè akụkụ na a bath nwere nnu ngwọta na-ahụ gabiga ya ihe eletrik. A ngwa, a oyi akwa nke zinc, na ọkpụrụkpụ nke nke - 0.5-10 microns.

Ndị dị otú ahụ na-arụ ọrụ n'oge a metal Rolling bụ nnọọ ewu ewu, ọ bụ ike overestimate, mgbe na-arụ n'elu a na-echebe site ọ bụla metụtara.

Otsinovka enye corrosion na-eguzogide nke ígwè ngwaahịa, mgbe ahụ, ha ga-eji maka mmepụta nke ngwọta oké egwu aga-eme. Ọ na-eji maka akpakanamde ụlọ ọrụ, na-ewu, mmanụ na gas. Na ojiji nke zinc ígwè mpempe akwụkwọ arọ nke gị na mgbanwe ubé, ma na-ewe na Njirimara nke nchedo corrosion Filiks n'ihi na ezi a ogologo oge, ọ pụrụ ịbụ ruo afọ 50.

Àgwà nke esichara mpempe akwụkwọ n'elu ga-dị na GOST 16523-89, mpempe akwụkwọ obosara - si 710 mm na 1800 mm, ya ọkpụrụkpụ nwere ike n'etiti 0,5 mm na dị elu dị ka 5 mm.

Steel mpempe akwụkwọ na-ekewa 3 ọmụmụ, dabere na ọkpụrụkpụ nke zinc Ibé akwụkwọ:

- klas "n" nwere a ọkpụrụkpụ nke 40 microns na a mkpuchi 60;

- klas "1" - 18 microns na ruo 40;

- klas "2" - site na 10 microns 18 microns. Steel iche iche nke Ibé akwụkwọ nwere ike ot na HS-Ibé akwụkwọ iji jiri ha oyi akpụ. Ọ bụla dị iche iche nke ígwè Ibé akwụkwọ oyi-stamping, "H" maka akụkụ site nkịtị; "D" maka usoro nke n'ichepụta miri-mmasị akụkụ; maka miri nnọọ emi ịbịaru usoro eji akara "HS"; n'okpuru oyi àgwà - "CP"; maka ụdi sere, Ibé akwụkwọ "PC"; marking "ON" na-eji maka general-nzube ngwaahịa.
