Hot Machining

Key Features of Hot Working:

1. Plastic Deformation:

• Hot working utilizes the plasticity of materials at elevated temperatures, allowing controlled deformation to achieve the desired manufacturing shapes.

2. Reduced Hardness:

• Heating metals softens them, reducing hardness and facilitating the formation of more complex shapes and structures.

3. Improved Mechanical Properties:

• Hot working contributes to enhanced toughness, tensile strength, and fatigue resistance of metals.

4. Stress Relief:

• Hot working at high temperatures can help alleviate residual stresses in metals, enhancing the stability of components.

5. Applicable to Various Metals:

• Hot working is suitable for a variety of metals, including steel, aluminum, copper, and others.

Common Methods of Hot Working:

1. Forging:

• Utilizes impact or pressure to deform metal at high temperatures, often used for manufacturing high-strength, tough components.

2. Rolling:

• Involves passing metal through rolling mills for plastic deformation to obtain the desired shapes and dimensions, widely used in the production of sheets, bars, and more.

3. Extrusion:

• Heated metal is forced through a die to produce components with the required cross-section, commonly used for producing profiles and sections.

Applications of Hot Working:

• Aerospace Industry:

• Used for manufacturing components such as aircraft engine parts and structural elements.

• Automotive Manufacturing:

• Applied in the production of engine components, chassis parts, wheels, and more.

• Energy Sector:

• Utilized for manufacturing components like gas turbine blades and nuclear power equipment parts.

• Construction Industry:

• Applicable for manufacturing structural components and large profiles.
