Características e usos de placas de aço compostas resistentes ao desgaste

Placas de aço compostas resistentes ao desgaste são versáteis, permitindo o corte, flexão, e soldagem. Eles podem ser conectados a outras estruturas através de soldagem ou conexões aparafusadas, tornando-os eficientes para manutenção e prolongando a vida útil dos equipamentos. Isso reduz o tempo de inatividade e diminui o investimento de capital.

1. Gas Cutting Characteristics

Wear-resistant composite steel plates can be gas-cut like ordinary steel plates. To prevent cracks during gas cutting, high gas and oxygen pressure should be used, and the cutting speed should be reduced. In special cases, preheating the plate to 60℃-90℃ is recommended.

2. Cold Forming Characteristics

Despite their high strength and hardness, these steel plates have good cold bending performance and can be cold-formed. To avoid cracking at the edges during cold processing, the flame-cut or sheared edges in the bending area should be ground.

3. Hot Forming Characteristics

The steel plates exhibit good hot processing performance at temperatures up to 350℃. If the temperature exceeds the phase change point (por exemplo, above Ar), low-temperature tempering between 250℃-350℃ is required after hot processing.

4. Machining Characteristics

These plates have excellent cutting and shearing properties. When machining, adjust the feed amount and speed according to the plate’s hardness and the cutting tool used. Tools made of high-speed steel or cemented carbide are typically required. For cutting and grinding, carbide surface tools are recommended.

5. Método de soldagem

The steel plates can be welded using ordinary arc welding and gas-shielded welding to achieve strong joints. For welding high-hardness plates, preheating is advised, with the temperature specified in the welding guidelines.

Aplicações

Wear-resistant composite steel plates are widely used in industries such as mining machinery, coal mining machinery, environmental protection machinery, and engineering machinery. Eles também são comumente usados como aço estrutural de alta resistência, com um limite de escoamento de ≥800 MPa.
