I. Analysis of Thin Plate Lamination Issues

1. Steel Composition

   • High content of impurities such as sulfur and phosphorus: These impurities can easily form defects in steel, reducing its strength and toughness, and thereby increasing the risk of lamination.
   • Chromium content affecting heating uniformity: Uneven distribution of chromium in steel can lead to inconsistent thermal expansion and contraction during heating, resulting in lamination.

2. Hot Rolling Process

   • Improper temperature control: Too low a hot rolling temperature or uneven temperature distribution can cause inconsistent deformation of various parts of the plate during rolling, leading to lamination.
   • Poor mill condition: Factors such as roll wear, roll pass design, and pressure control all affect plate quality. If the mill is in poor condition, it may cause uneven pressure on the plate during rolling, resulting in lamination.

3. Production Equipment

   • Heating furnace temperature control failure or unevenness: The heating furnace is a critical piece of equipment in the hot rolling process. If its temperature is uncontrolled or uneven, it can lead to inconsistent temperatures in various parts of the plate during heating, causing lamination.
   • Excessively low rolling pressure: Rolling pressure is an important parameter in the rolling process. If it is too low, the plate may not be fully compressed during rolling, resulting in lamination.

II. Improvement Measures

1. Optimize Steel Composition

   • Strictly control the content of impurities such as sulfur and phosphorus to ensure steel purity.
   • Improve the steel structure through alloying methods to increase steel strength and toughness.
   • Optimize chromium distribution to improve heating uniformity of the plate.

2. Improve Hot Rolling Process

   • Precisely control the hot rolling temperature to ensure consistent temperatures in various parts of the plate during rolling.
   • Regularly maintain and repair the mill to ensure optimal conditions for roll wear, roll pass design, and pressure control.
   • Adopt advanced rolling techniques, such as cross rolling, to improve plate quality.

3. Upgrade Production Equipment

   • Use high-precision, high-stability heating furnaces and rolling mills.
   • Strengthen maintenance and repair of production equipment to ensure they are in good working condition.
   • Introduce advanced automation control systems to achieve precise control of the production process.

4. Improve Employee Quality

   • Strengthen training and education of production employees to improve their professionalism and operating skills.
   • Regularly organize technical exchanges and seminars to promote knowledge sharing and experience exchange among employees.
   • Establish and improve a quality management system to ensure that employees strictly follow quality standards and operating procedures during production.

In summary, by optimizing steel composition, improving the hot rolling process, upgrading production equipment, and improving employee quality, the thin plate lamination issues in the molybdenum plate rolling process can be effectively addressed. The implementation of these measures will help improve the quality and production efficiency of molybdenum plates, making a greater contribution to the development of the metal processing industry.
