Coiled plate leh hot-rolled coil te hi steel product hrang hrang pahnih an ni. Coiled plate hi finished steel a ni a, a chung lam quality tha tak leh dimensional accuracy sang tak a nei a ni. Hot-rolled coil erawh chu high-temperature rolling hnuaia billet atanga siam steel a ni thung. A surface quality a tha lo hle a, a dimensional accuracy pawh a hniam hle. A danglamna bik chu hetiang hi a ni:
1. Processing technique hrang hrang .
Coiled plate hi roughing, intermediate, leh finishing mill hmanga siam a ni. Rolling pass tam tak hnuah chuan smooth, wrinkle-free surface leh stable dimensions a nei thei a ni. Hot-rolled coil erawh chu high-temperature rolling hmanga siam a ni a, chu chuan surface wrinkles leh burr leh dimensional stability tha lo tak a siam a ni.
2. Application hrang hrang .
Coiled plate hi steel structure, automotive parts, leh home appliances siamnaah hman tlanglawn a ni a, galvanized emaw painted emaw pawh a ni thei. Hot-rolled coil erawh chu a bul berah chuan pipe leh tube ang chi thil siamnaah hman a ni a, chu chu bending leh press-forming a ngai a ni.
3. Hnathawh dan inang lo .
Rolled steel coil hi a hring deuh a, mahse formability, plasticity leh weldability tha tak tak a nei a ni. Hot-rolled steel coil te hi a thick zawk a, mahse toughness leh strength sang zawk an nei thung.
