Mbale yachitsulo yosatha kuvala

Mapepala achitsulo osatha kutha amakhala ndi mbale yachitsulo yopanda mpweya wambiri komanso wosanjikiza wosatha kutha kutha, ndipo wosanjikiza wosatha ku ...

Chigawo chosatha kutha kwa aloyi ndi zinthu zoyambira zimalumikizidwa ndi zitsulo. Pogwiritsa ntchito zida zapadera komanso njira yolumikizira yokha, waya wa aloyi wolimba kwambiri, wodziteteza wokha umalumikizidwa mofanana ku zinthu zoyambira. Chigawo chophatikizanacho chikhoza kukhala chimodzi, ziwiri, kapena zingapo. Chifukwa cha kusiyana kwa ma aloyi, ming'alu yopingasa yofanana imachitika panthawi ya lamination, chizindikiro cha mbale zachitsulo zosatha kutha.

Chigawo chosatha kutha kwa alloy chimapangidwa makamaka ndi chromium alloy, ndipo zinthu zina zosakaniza monga manganese, molybdenum, niobium, ndi nickel zimawonjezeredwa. Ma carbide omwe ali mu kapangidwe ka metallographic ndi a fibrous, ndipo ulusi wake umayang'ana molunjika pamwamba. Kulimba kwa carbide pang'ono kumatha kufika pa HV 1700-2000, ndipo kulimba kwa pamwamba kumatha kufika pa HRC 58-62. Ma carbide a alloy ndi okhazikika kwambiri kutentha kwambiri, kusunga kuuma kwakukulu komanso kukana bwino okosijeni, zomwe zimathandiza kuti azigwira ntchito mokwanira mkati mwa kutentha mpaka 500°C.

Chigawo chosatha kutha kuoneka m'mapangidwe opapatiza (2.5-3.5mm) kapena m'lifupi (8-12mm), komanso mawonekedwe opindika (S ndi W). Makamaka opangidwa ndi ma alloy a chromium, ma alloy awa alinso ndi manganese, molybdenum, niobium, nickel, ndi boron. Ma carbides amagawidwa mu kapangidwe ka ulusi mu kapangidwe ka metallographic, ndi ulusi womwe ukuyenda molunjika pamwamba. Ndi kuchuluka kwa carbide kwa 40-60%, kuuma pang'ono kumatha kufika pa HV1700, ndipo kuuma kwa pamwamba kumatha kufika pa HRC58-62. Ma plate achitsulo osatha kutha kutha kugawidwa m'magulu atatu: cholinga chachikulu, chosatha kukhudza komanso chosatha kutentha kwambiri. Kukhuthala konse kwa ma plate achitsulo osatha kutha kutha kukhala ang'onoang'ono ngati 5.5 (2.5+3) mm ndi makulidwe ngati 30 (15+15) mm. Mapepala achitsulo osatha kutha kukulungidwa m'mapaipi osatha kutha omwe ali ndi mainchesi osachepera a DN200, ndipo amatha kusinthidwa kukhala zigongono zosatha kutha, ma tee osatha kutha ndi zochepetsera kutha ...
