Plate rolling machines play a crucial role in the metal processing industry, shaping sheets and extrusions into various forms and curves. However, one of the most critical factors in Plate rolling machine design and operation is the choice of material. For instance, when rolling sheets of the same thickness, materials with higher yield strength will demand higher pressure from the Plate rolling machine. Neglecting this factor may lead to defects or deformation at the edges of processed materials.
Nowadays, steel is much stronger than before, resulting in increased requirements for Plate rolling machine roll pressures. To address this, the ASME (American Society of Mechanical Engineers) has established corresponding standards, categorizing various types of steel, such as A36, A516 grade 70, Hardox 400/500 series, AR 200/300 series, and others. Different steel specifications correspond to varying roll pressures.
Metal tempering brittleness, yield strength, and the intended use of materials are also crucial factors that Plate rolling machine manufacturers need to consider. This becomes especially vital since the reform in the steelmaking industry over the past decades, during which materials like mild steel are no longer popular.
Impact of Material Choice
- Yield Strength and Pressure Requirements: The yield strength of the material significantly affects the pressure requirements for Plate rolling machines. For sheets of the same thickness, materials with higher yield strength will demand higher pressure from the Plate rolling machine. Neglecting this factor may lead to defects or deformation in the processed material.
- Steel Strength and ASME Standards: Modern steel materials generally possess higher strength, resulting in increased pressure requirements for Plate rolling machines. ASME has established standards that categorize different types of steel, such as A36, A516 grade 70, Hardox 400/500 series, AR 200/300 series, and others. Each steel specification corresponds to specific roll pressures.
- Metal Temper Brittleness and Yield Strength: Metal tempering brittleness refers to the brittle change within a specific temperature range of the metal. Manufacturers of Plate rolling machines need to consider temper brittleness and yield strength when dealing with different materials. This has become increasingly important in light of the reforms in the steelmaking industry, where traditional mild steel has been replaced.
Importance of the Influencing Factors
