Answer: Fine material principle to reduce the amount of slag. Reasonable slagging system. Reasonable oxygen supply system, loading system to reduce mechanical spattering. Thermal compensation technology, consume more scrap to reduce chemical burn loss. Reasonable re-blowing technology.    

Las chapas laminadas en frío tienen una buena calidad superficial, una alta precisión dimensional y no tienen óxido debido al laminado a temperatura ambiente. Después del tratamiento de recocido, sus propiedades mecánicas y tecnológicas son mejores que las de las chapas laminadas en caliente, y se utilizan principalmente en la…

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…
