Characteristics of Hot-rolled Steel Plates:
Hot-rolled steel plates are made by high-temperature processing and have the following characteristics:
1. High strength: The strength of hot-rolled steel plates is much higher than that of general steel plates, and they can withstand greater pressure and impact.
2. Good wear resistance: The surface of hot-rolled steel plates has been processed and has good wear resistance and corrosion resistance.
3. High dimensional accuracy: The dimensional accuracy of hot-rolled steel plates is relatively high, which can meet the production requirements of complex components.
4. Surface quality: The surface of hot-rolled steel plates has oxide scales, low smoothness, but good plasticity, and is generally medium and thick plates.
5. Mechanical properties: Hot-rolled steel plates have high plasticity and weldability, but low hardness, and are suitable for the production of general structures and welded structures.
Processing process:
The production process of hot-rolled steel plates includes heating the ingot or continuous casting billet to a high temperature, and then rolling it through the rough rolling and finishing rolling units to finally obtain the required thickness and size, and its thickness is generally above 1.2mm. The width and thickness of the hot-rolled steel plate can be adjusted by controlling the temperature and pressure during the rolling process.
Application of hot-rolled steel plates:
Hot-rolled steel plates are an important material widely used in many industrial fields. Its main uses are as follows:
1. Construction field
