Ebifaananyi by’emizingo gy’okusika .

Stretch Roll .

Okuva okusika omuguwa okungi bwe kwetaagisa mu kitundu eky’ennyogoga eky’amangu, kyetaagisa okuwa ekyuma ekiziyiza okusika ku kitundu ekifuluma n’ekiyingira mu kitundu kino, ekisaanira okwawula obulungi okusika wakati w’ekitundu kino n’ebirala.

Ebifaananyi by’ekintu ekiyitibwa tension roller biri bwe biti:

Omulongooti 3.24.16 Ebifaananyi by’okusika omuguwa .

Omuzingo gumu mu buli seti ya tension rollers (omuzingo ogw’okusatu ogw’omuzingo gw’okusika oguyingira n’omuzingo ogusooka ogw’omuzingo gw’okusika omuguwa ogufuluma) gulina ekizibiti ekikwata okukuuma okusika nga yuniti eyimiridde. Ekizibiti ekikutte kirimu bulooka za buleeki / paadi n’ekintu ekikola empewo.

Okusiiga roller ne convex .

Omuzingo gw’ekikoomi gutuusibwa n’obukaluba obw’amaanyi, okusobola okukuuma okunywerera okulungi ku strip n’okuziyiza skid, ekiyinza okuvaamu nodules ne scratches. Ekigendererwa ky’okusiiga ebbugumu eringi: a) Okulongoosa obuziyiza bw’okwambala kw’ekikoomi ky’ekikoomi ku bbugumu erya waggulu, okulongoosa obukaluba, CR25NI20, CR28NI48, n’okugwa kw’obukaluba, obukaluba ku ngulu bukendeera, kireeta okuseerera kw’omuguwa, okusika si kyangu kuteekawo; b) Ekigendererwa ekyokubiri kwe kuziyiza ebizimba, okufukirira kuva ku ngulu w’omuguwa; oba olw’okutonnya kw’ekyuma kya strip mu bbugumu erya waggulu.

Enkola y’okufuuyira: A), Tekinologiya w’okufuuyira mu ddoboozi ery’omwanguka, ebbugumu ly’okukola<500℃, using materials: Co base alloy, good low temperature wear resistance, oxidation resistance and good corrosion resistance; working temperature <900℃, using material: NiCr alloy, good thermal corrosion resistance and wear resistance under medium and high temperature conditions, corrosion resistance, corrosion resistance, micro vibration and grinding wear, good corrosion resistance, good wear and oxidation resistance at medium and high temperature.

B), Explosion spraying technology, working temperature>900℃, Okukozesa ebintu: alloy + oxide (ebyuma ceramics), high temperature wear resistance, okugumira ebbugumu eringi oxidation, okuziyiza okuyungibwa ku bbugumu eringi (okuziyiza okukulugguka).

Ekirowoozo kya dizayini y’ebintu ebigumira ebbugumu eringi ye: ekyuma (ekyuma aloy) + ebyuma ebikolebwa mu bbulooka (ebitali-ekyuma). Obukakanyavu obusinga obulungi obw’ebbugumu eringi si-ebyuma ebikolebwa mu keramiki. Okusobola okukakasa nti keramiki tegwa, ekitundu ky’ekyuma (ekiyungo ky’okusiba) n’ebyuma bya keramiki (ebitali-ekyuma) (ekintu ekinyweza) birina okugattibwako okukakasa amaanyi, okuziyiza okuyiwa n’amaanyi, gamba nga LCO-17,56. 1001000 ddiguli amazzi okutonnya ebigezo.

Enkola y’okusiiga ey’ekikoomi eky’ebbugumu eringi ey’omugabi w’ekikoomi okusinga y’emu, kwe kugamba, ekitundu ky’ebbugumu, ekitundu ky’ebbugumu ekitundu n’ekitundu ky’okunyogoza bitwala ekizigo ekiziyiza ebbugumu ery’amaanyi, n’ekizigo kya 950 oba 1050 mu kitundu ky’okufumbisa n’ekitundu 050℃resistance coating. Obukaluba bwa coated roller buli wakati wa 1 ne 10 μm RA. Waliwo abasuubuzi abawerako abasiiga ebizigo n’ebika mu nsi yonna, nga bino wammanga:

Omulongooti 3.24.18 Olukalala lw’ebintu ebikuba ebikoomi ebibuguma n’abagaba ebintu n’ebika .

Roller drive motor: Enkola ya transmission ya strip steel evugirwa motor ya motor ne gear, era ebalwa okusinziira ku bino wammanga ebikulu data: sipiidi esinga obunene 420 mmHg, acceleration / deceleration rate 10 MP M/sec, braking rate 30 MP M/sec, maximum strip tension 15n / mm², Enjawulo y’okusika kw’omuguwa ogusinga obunene 0.1 N/mm2 / Roll (ebbugumu / ebbugumu), 0.3 N/mm2 / Roll (okunyogoza / okufuluma).
