SA553TypeI.钢板热连轧
SA553TypeI. steel plate with continuous casting slab or colostrum slab as raw material, heated by a step-by-step heating furnace, high-pressure water descaling and then into the roughing mill, rough-rolled material through the cutting head, tail, and then into the finishing mill, the implementation of computer-controlled rolling, after the final rolling is through laminar cooling (computer-controlled cooling rate) and coiler coiling, become a straight roll. The head and tail of straight hair curls are often tongue-shaped and fishtail-shaped, with poor thickness and width accuracy, and there are often defects such as waves, folds, and towers on the edges.
SA553TypeI steel plate has a heavier coil weight, and the inner diameter of the steel coil is 760mm. (The general pipe industry likes to use it.) After the straight hair curl is processed by the finishing line such as cutting the head, cutting the tail, cutting the edge, straightening and leveling for multiple passes, it is then cut or rewound to become: hot-rolled steel plate, flat hot-rolled steel coil, longitudinal cutting belt and other products. If the hot-rolled finishing coil is pickled, the oxide scale is removed and oiled, and it becomes a hot-rolled pickled coil. The product has a tendency to partially replace cold-rolled plate, the price is moderate, and it is deeply loved by the majority of users.
SA553TypeI.钢板冷连轧
SA553TypeI. steel plate with hot-rolled steel coil as raw material, after pickling to remove the oxide scale for cold continuous rolling, the finished product is rolled hard coil, due to the continuous cold deformation caused by cold work hardening to roll the strength of the hard coil, hardness rises, toughness and plastic index decreases, so the stamping performance will deteriorate, can only be used for simple deformation of parts. Rolled hard coils can be used as raw materials for hot-dip galvanizing plants, because hot-dip galvanizing units are provided with annealing lines. The weight of rolled hard coils is generally 6~13.5 tons, and the inner diameter of steel coils is 610mm.
SA553TypeI. steel plate is generally cold rolled plate and coil should be annealed continuously (CAPL unit) or bell furnace annealing to eliminate cold work hardening and rolling stress, to achieve the mechanical properties specified in the corresponding standards.
The surface quality, appearance and dimensional accuracy of SA553TypeI. steel plate cold-rolled steel plate are better than that of hot-rolled plate, and the thickness of its product is about .0.18mm, so it is favored by the majority of users. Cold-rolled steel coils are used as substrates for deep processing of products to become high value-added products.
SA553 Type I steel plate First of all, from the performance point of view, SA553 Type I steel plate has strong high temperature resistance, and its use temperature range is between minus 196 degrees Celsius and 450 degrees Celsius, which can still maintain high strength and toughness in this temperature range. SA553 Type II steel plate, on the other hand, pays more attention to the processing performance at low temperatures, with a service temperature range of minus 196 degrees Celsius to 380 degrees Celsius, and has good low-temperature impact toughness and weldability.
Secondly, from the perspective of application, SA553 Type I steel plate is mainly used for nuclear reactor pressure vessels in nuclear reactor manufacturing, and can also be used in the manufacture of other important equipment under low temperature conditions. SA553 Type II steel plate, on the other hand, is mainly used in the manufacture of cryogenic equipment such as hydrogen storage tanks, and can also be used in the manufacture of other important equipment under low temperature conditions such as nuclear power plants.
