Cold-rolled sheets have good surface quality, high dimensional accuracy and no oxide sheet due to rolled at room temperature. After annealing treatment, its mechanical properties and technological properties are better than hot-rolled sheet, mostly used of automotive, electrical products, locomotives, aviation, precision instruments, food and other industries. In the planning and design…
1Cr17Mn6Ni5N stainless steel is instead of grade 1Cr17Ni7, it is with magnetic properties after cold rolled, used for railroad cars. 1Cr17Ni7 stainless steel has high strength after cold working for railroad cars, conveyor belts, bolts and nuts. 1Cr18Ni9 stainless steel has high strength after cold working, but the elongation is…
Ferritic stainless steel is known for its high corrosion and oxidation resistance, but it has lower plasticity and toughness. Common grades include 409 and 430, which are mainly used in automotive and construction applications. Magnetic Properties: Ferritic stainless steel is magnetic. Thermal Expansion: The thermal expansion rate of ferritic stainless…
A single cold rolling mill can handle small-scale rolling tasks with lower initial equipment investment. Its production organization is more flexible, allowing for quick adjustments to specifications based on market demand. The old system’s operation and production process relied heavily on operator input setting and field adjustments, with fault diagnosis…
Stainless steel has high deformation resistance, generally twice that of ordinary carbon steel. During cold working, deformed martensite forms, causing a rapid work hardening rate and requiring greater rolling force and load. Requirements Stainless Steel Cold Rolling Mill Should Meet Work rolls should be of small diameter as much as…
Roll flaw detection is essential for almost all high-standard rolling mill. Common methods for roll flaw detection include magnetic particle flaw detection, penetrant color flaw detection, eddy current flaw detection, and ultrasonic flaw detection. Magnetic Particle Flaw Detection: This technology is primarily used to identify surface cracks on the roll body…
New-product: 1100MPa High-strength Solid Wire At present, there isn’t a matching welding material with the1100MPa high-strength steel plate, most of the industry is forced to use 900MPa grade wire, in the design to avoid the welding joint force, which brings more trouble to the equipment design, but also is the…
New or expanded bars or wire rod production line is mostly used in H/V arrangement of short-stress rolling mill, it is compared with the traditional mill, this compact rolling line reduces the weight of equipment and plant construction costs. The characteristics of the short stress rolling mill: The rigidity of the mill is good, and the dimensional…
The rolls of hot rolling mill or cold cooling mill act key role in the rolling process. The shape (convexity, concavity, taper,etc) of the roll can impact the quality of final products. In the rolling process along the length of the roll, the distance between the upper and lower rolls should…
The smelting process for the production of stainless steel is mainly divided into one-step, two-step and three-step, of which the two-step process of EAF+AOD (Electric Arc Furnace+Argon Oxygen Refining Furnace) accounts for about 70%, and the three-step process accounts for about 20%. With the low phosphorus iron is widely used…
