Mbale ya Chromium Carbide Overlay CCO

Mbale yovala pamwamba pa chromium carbidendi metallurgic ya bimetallic-mbale yophatikizika yolumikizidwa. Ili ndi chofewa-carbon steel base substrate ndi carbon steel base substrate yokhala ndi mphamvu zambiri-chromium yolimba-chophimba cha alloy chomwe chimayikidwa ndi chotsegulira chokha-kuwotcherera kwa arc hardfacing, ndi kuuma kwa pamwamba kufika pa HRC 58-65.

Ubwino Waukulu

1. 1.Kukana Kwabwino Kwambiri Kovala

   Ma carbide olimba ambiri a Cr₇C₃ amapangidwa mkati mwa gawo lophimba. Kukana kwake kukwiya ndi 15-Kuchulukitsa nthawi 20 kuposa chitsulo wamba cha kaboni, 2-Kuposa katatu kuposa zovala za NM zokulungidwa-Ma plate achitsulo osagwira ntchito. Pakakhala kukokoloka kwa nthaka, nthawi yake yogwira ntchito ndi 3-Kutalika nthawi 5 kuposa nthawi zonse-zitsulo zopangidwa ndi manganese. Zabwino kwambiri powononga tinthu tating'onoting'ono komanso kuwononga kwambiri-zochitika zofufuzira zinthu mwachangu.

2. 2. Kapangidwe ka Bimetallic ka Pakati-Kukana Kukhudzidwa
   

   Chitsulo cholimba cha Q235/Q345 chimakhala ndi zinthu zowononga pomwe pamwamba pake pamakhala kuuma kwambiri. Chitsulo cholimbacho chimalumikizidwa pansi, kukana kukula kwakukulu.-kugawa malo. Poyerekeza ndi malo okwera kwambiri-Chitsulo chopangidwa ndi chromium, sichimasweka mosavuta ndi kusweka.

3. 3.Kutha Kukonza Bwino & Kusinthasintha Pa-Kusintha kwa Malo

   Imathandizira kudula, kuboola, kupindika ndi kugubuduza plasma kuti ipange ma liners opindika.-Kuyika n'kotheka (kuwotcherera kuyenera kuchitika kokha kumbali ya substrate).-to-kukula kulipo popanda kuponyera nkhungu, zomwe zimathandiza kuti chingwe chifupi chikhale cholimba-nthawi zazing'ono-maoda a gulu.

4. 4. Wapamwamba-Magwiridwe antchito a kutentha

   Khola lalitali-utumiki wa nthawi yayitali mpaka 550-600 °C. Chigawo cholimba chimalimbana ndi kufewa pansi pa kutentha kwakukulu-kutentha kwa kutentha, koyenera kuzizira zomera za simenti, mphepo zamkuntho ndi malasha-mapaipi amagetsi oyaka.

5. 5. Kukonza ndi Kukonza Kotsika

   Palibe chifukwa chochotsera gawo lonselo pamene pamwamba pake pokha patha.-tsamba lawebusayiti-Kukonza malo olimba n'kotheka. Gawo limodzi lokha-kusintha kwa chidutswa kumachepetsa zotsalira-ndalama zina ndi nthawi yoti zida zisagwire ntchito.

6. 6. Mtengo-Yankho Lothandiza

   Mtengo wokwera kwambiri-chromium alloy imagwiritsidwa ntchito pokhapokha pa nthawi yogwiritsidwa ntchito-malo oyang'ana pansi pomwe ali otsika-chitsulo cha kaboni chotsika mtengo chimagwiritsidwa ntchito ngati maziko, kukulitsa kugwiritsa ntchito bwino zinthu. Popanda ndalama zoyambira zokonzera zinthu zazing'ono-Maoda a batch, ndalama zonse zogwirira ntchito ndi kukonza zachepetsedwa kwambiri.

7. 7. Kusintha Kosinthika

   Kukhuthala kwa substrate ndi makulidwe a hardfacing overlayer (3)-12 mm) ndi zosinthika. Ma plates athyathyathya, magawo opindika komanso apadera-Ma liners ooneka ngati mawonekedwe angapangidwe kuti agwirizane mwachindunji m'ma chutes, ma hopper ndi malo osamutsira.

Zoletsa Zofunikira

1. Ming'alu yaing'ono ya netiweki pamwamba pa pamwamba ndi zinthu zomwe zimapangidwa bwino. Sizimawononga magwiridwe antchito koma sizingapirire kuvulala kwambiri.
2. Ntchito zowotcherera siziyenera kuchitika mwachindunji pa cholimba-wosanjikiza wozungulira nkhope.

Mapulogalamu Odziwika

Ma chute liners, ma hopper liners, kusamutsa-Ma point wear plates ogwiritsidwa ntchito mu migodi; ma grate coolers, ma cyclone liners ndi mapaipi a zomera za simenti; malasha-kusamalira ndi phulusa-njira zochotsera magetsi amagetsi; kutsitsa katundu ndi kuteteza malo osungiramo zinthu zapadoko, makamaka poyeretsa-kuvala zinthu zogwirira ntchito.
