NOTE: Hot-rolling and cold-rolling should not be mistaken for different grades of steel. Steels of different grades can be produced as hot-rolled or cold-rolled. HOT-ROLLED STEEL. Hot-rolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature; a heat that typically exceeds 1000° F.

Cold rolling is used to reduce the temperature of the material being worked with while also increase how hard and strong the material gets during the rolling mill process. During this process, the overall finish and granule structure of the …
Cold Rolled Steels can be joined using accepted welding practices. SURFACE FINISH Cold Rolled Steels are manufactured with a matte finish obtained by rolling with specially roughened rolls on the cold mill and the temper mill. This finish helps to maintain effective lubrication during metal forming and improves the appearance of painted surfaces.

Forged Cold Mill Rolls Pinch Rolls Edger Rolls Leveler Rolls Specialty Rolls Roll Repair For hot strip mill Edger applications, Xtek developed another special steel grade with superior resistance to the thermal fatigue and firecracking so ...
Reasons for Mill Roll Cracks. Owing to the high wear resistance and minimal plastic deformation of the cold mill roll, it is required that the surface of the cold mill roll have higher hardness and thicker hardening layer.The material of cold roll is 9Cr2Mo. The surface hardness of HS96 is obtained by surface quenching and tempering.
Cold Rolled. Rolled in our exceptional five-stand, six-high cold mill and annealed on our state-of-the-art continuous annealing facility UPI Cold Rolled Annealed has exceptionally tight gauge and shape performance, superior mechanical properties, and top-of-the-line surface quality.
Driven by the technology of pulling and roll manufacturing in the cold rolling industry, the requirements for increasing the wear resistance, roughness retention, hardness uniformity and anti-accident of cold rolls are increasing, with the aim of achieving free rolling., rolling high-grade plates, reducing roll consumption and so on.
The free torsional stiffness of hot-rolled section steel is higher than that of cold-rolled section steel, so the torsional resistance of hot-rolled section steel is better than that of cold-rolled section steel. Free send inquiry to [email protected] if any needs. Whatsapp/Wechat:+86.

As a world leader with more than 80 references over 60 years, our DMS 20Hi cold rolling mills go beyond expectations to process stainless or silicon steels with ultimate surface quality standards. We're also proud to announce a world first - a GIGA steel mill for ultra-advanced high-strength steel for the automotive industry. Now available with a roll change robot.
Cold rolling can be used to change the gauge of steel sheet metal. Cold rolling is a process used in manufacturing and finishing environments to change the thickness, or gauge, of metals or glass. Used mostly in steel mills, cold rolling involves threading flattened steel into a machine that advances the material through a set of rolls.
Cold rolling is a work hardening process used to change the structure of metals and is often used to process stainless steel. Cold rolled stainless steel as a raw material has a wide variety of applications in medical, aerospace and automotive engineering.
How Does a Cold Rolling Mill Work? The process of cold rolling a metal alloy starts with either sheet metal or strip coil. These materials are placed into large rollers, which compress it down and squeeze it under high pressure just below its ultimate tensile strength.
