Cold Rolling hte Hot Rolling lapran na shai hkat ai lam ni hpe galaw ai ladat ni

Nickel-based alloys ni hpe katsi ai hku shinggrup ai hte katsi ai hku shinggrup ai gaw ahkyak ai shinggrup ai lam lahkawng rai nna, lahkawng yan gaw shanhte a plastic galaw ai lam hpe daw jau ai. Shanhte gaw galaw sa wa ai lam hte galaw shapraw ai arung arai ni a arawn alai ni hta grai shai hkat nna, shanhte a bungli ni gaw langai hte langai hpe madi shadaw ya ai.

 

Hot rolling hpe gaw, n-gun bai jat wa ai n-gun (1000-1200℃) hta jan nna galaw ai. Cast billets (sh) forged billets hpe raw material hku jai lang nna, homogenizing annealing, katsi ai, multi-pass rolling (10%-30% shayawm ai hte 1-5 m/s lawan ai), lawan ai hku katsi ai, n-gun shayawm ai zawn re ai ladat ni hpe lai di ra ai. Shi a yaw shada ai lam gaw, n-gun n rawng ai hpe yeng seng kau na matu, n-gun rawng ai n-gun ni hpe gram lajang na matu, n-gun rawng ai n-gun rawng ai arung arai ni ( 3mm hta grau kaba ai (sh) maren) rai nga ai, n-gun rawng ai hte n-gun rawng ai plate ni hte strip billets ni hpe galaw na matu re. Shi gaw deformation kaba hpe galaw ya lu ai hte alloy a mechanical atsam ni hpe grau kaja hkra galaw ya lu ai akyu ni nga ai. Raitim, shi gaw n kaja ai ntsa nsam hte shadawn shadang hkrak ai lam (±0.5mm hkam sharang lu ai) hte manu n law ai majaw, Nuclear wan jak a hka n-gun shapraw ai jak ni a bunghku kaba ai hka htung billets zawn re ai mabyin masa ni a matu htuk manu ai.

 

Cold rolling hpe gaw, n-gun bai jat wa ai n-gun (nta n-gun - 200℃) a lawu kaw galaw ai. Hot-rolled strips (sh) thin plates ni hpe billets hku lang nna, ntsa lam hpe gram lajang ngut ai hpang, multi-pass rolling galaw ai (5%{9}}20% pass langai sha shayawm ai, plasticity hpe bai gram lajang na matu, lapran na annealings law law ra ai), dai hpang, htum hkra shinggrup ai, mai byin ai heat at, galaw ai. Shi a yaw shada ai lam gaw, n-gun hpe shayawm na matu, dimensional accuracy (±0.005mm du hkra hkam sharang lu ai) hte ntsa lam hpe grau kaja hkra galaw na matu, bungli hpe ngang kang hkra galaw ai hku nna n-gun hpe jat wa hkra galaw na matu re. Shi gaw n-gun n rawng ai plate ni hte ultra-n-gun n rawng ai strip ni hpe shapraw lu ai ( 3mm hta n law ai (sh) maren sha re). Manu kaba ai hte, aero-engine ni a n-gun ja ai-katsi ai gaskets zawn re ai hkrak tup ai arung arai ni a matu htuk manu ai.
