Stainless steel tubes annealing eng tak tak tichhe thei thilte
Tunah chuan stainless steel pipe hi market-ah hman a ni tawh a, nun kawng tinrengah a figure a nei a, hmun pawimawh tak a chang bawk. Decorative pipe nena khaikhin chuan stainless steel industrial pipe hian added value a nei sang zawk a, high-end transformation-a industry tan breakthrough point pawimawh tak a ni chho mek a ni. Mahse stainless steel pipe hian industrial pipe standards zawm a duh a, a khauh hle. Hardness tihziaawmna tur, plasticity tihchangtlunna tur, grains tihthianghlim tur leh internal stress tihbo nan a tul tlangpui a, chu chuan annealing a mamawh a ni. Chu bakah, bright annealing thatna chu hetiang hi a ni: Stainless steel tube chu pawn lam bright surface-ah dah la, chu chuan automobile tube, food fluid tube leh pawn lam êng tak tak siamna atana mamawh sang dangte chu a phuhruk theih nan. Bright annealing of stainless steel hian pickling a mamawh lo a, a kalphung pawh boruak tichhe lo zawk a ni.
Influencing factor tam tak a awm a, stainless steel-a bright annealing quality nghawngtu ber chu: gas composition leh purity protection, heating leh cooling system te an ni.
1. Annealing temperature chu a temperature tarlan angin a thleng em tih .
Stainless steel-a heat treatment hi a tlangpuiin solid solution heat treatment a ni a, chu chu annealing tia hriat lar a ni. Bright annealing equipment hi stainless steel pipe on-line heated to 1050 °C atan hman a ni a, chutah chuan 100 °C hnuai lam rapid cooling chu hydrogen protection of special equipment hnuaiah hman a ni. Temperature hi influencing factor pawimawh tak a ni a, temperature hi 1040 atanga 1120°C inkar a thlen a ngai a ni.
2. Annealing boruak .
BA protective gas composition leh purity siamna atana hman thin chu a hmasa ber chu bright annealing a ni. A tlangpuiin, pure hydrogen hi annealing atmosphere atan hman a ni a, boruak thianghlimna chu 99.99% aia sang a ni. Atmosphere hmun dang chu inert gas a nih chuan a thianghlimna pawh a hniam deuh thei a, mahse oxygen vapor tam lutuk a awm loh a ngai tak zet a ni.
3. Annealing furnace eng tak chu pawn lam boruak atanga inkharkhip leh inkhung hran tur a ni .
annealing furnace-a thil awm dan (sealing properties) te. Annealing furnace eng tak chu pawn lam boruak atanga khar tur a ni a, a inthen tur a ni; Vent pakhat chauh hawn a ni (hydrogen gas discharged chu kangmei chhuah nan hman a ni). Inspection method chu annealing furnace ruhroah sahbawn tui hman a ni a, a leak leh leak loh en tur a ni; A leak theihna ber chu pipe leh pipe chhunga hmun a ni a, he hmuna sealing ring hi a inbel awlsam a, chuvangin check leh thlak a ni fo thin.
4. Gas venhimna atana gas pressure .
Trace leakage awm loh nan furnace chhunga protective gas chuan positive pressure engemaw chen a vawng reng tur a ni. Hydrogen protection gas a nih chuan a tlangpuiin 20 kbar aia sang a nih a ngai a ni.
5. Furnace charge a vawt em tih enfiah rawh .
Furnace loading hmasa ber chu a vawt tur a ni. Pahnihnaah chuan, furnace chhunga stainless steel pipe chu a tui lutuk em tih, a bik takin pipe chhungah hian khur a awm a, a leak lut lo a, chuti lo chuan stove boruak a tichhia ang.
