Advantages of Processing Carbon Steel and SPCC Steel on a Two-Stand Cold Rolling Mill

Carbon steel and SPCC steel are among the most widely demanded materials in the cold rolling industry, with extensive applications in automotive components, construction structures, appliance casings, and electronic devices. Ensuring consistent thickness precision and surface quality during mass production is the primary concern of customers. The Φ185/Φ560×700 Four-High Two-Stand Tandem Cold Rolling Mill offers significant advantages for processing these materials.

First, in thickness control, the two-stand tandem configuration allows stable reduction from 3.0 mm to 1.8 mm in a single pass. With the integration of a hydraulic Automatic Gauge Control (AGC) system, rolling force and roll gap can be adjusted in real time, ensuring that materials such as SPCC, which require strict tolerances, meet precise thickness consistency.

Second, in terms of surface quality, the mill’s four-high design—with work rolls supported by backup rolls—minimizes elastic deformation of the roll gap, thereby preventing defects. This results in flat, indentation-free sheet surfaces that fully meet the appearance requirements of SPCC for electronic components and premium appliances. For carbon steels like Q195 and Q235, the equipment ensures uniform microstructures essential for high strength and toughness.

Additionally, the mill features Siemens electrical control and a DC motor drive, enabling stable process parameters at high rolling speeds and avoiding thickness variations caused by speed fluctuations. The continuous production flow further guarantees efficiency and reliability in fulfilling bulk orders.

Overall, the Φ185/Φ560×700 Two-Stand Cold Rolling Mill combines precision, surface quality, and productivity in processing carbon steel and SPCC steel, providing manufacturers in automotive, electronics, and appliance industries with dependable performance and consistent results.
