Steel plates are flat steel materials

Steel plates are flat steel materials that are poured with molten steel and pressed after cooling. Steel plates are widely used in many fields such as construction, automobiles, ships, and machinery manufacturing due to their high strength, corrosion resistance, and strong mach-inability.

 

STEEL PLATE

1. Definition

 

Tomatoes are flat steel materials that are poured with molten steel and pressed after cooling. Steel plates are widely used in many fields such as construction, automobiles, ships, and machinery manufacturing due to their high strength, corrosion resistance, and strong mach-inability.

3. Production Process

 

Melting: First, raw materials such as iron ore and scrap steel are converted into molten steel through high-temperature smelting. This process is usually carried out in a steelmaking furnace (such as a converter or electric furnace).

 

Pouring: The molten steel is poured into a mold and cooled into a solid billet.

 

Rolling: The billet is then sent to a rolling mill for rolling. The rolling mill presses the billet into steel plates of different thicknesses and sizes through a series of rollers. This process can be divided into two methods: hot rolling and cold rolling. Hot rolling is carried out at high temperatures, while cold rolling is carried out at room temperature.

 

Cooling: The rolled steel plate needs to be cooled to ensure that its physical properties are stable.

 

Finishing: The cooled steel plate may undergo finishing processes such as flattening and shearing to meet the size requirements of the final product.

 

Inspection: Before final delivery, the steel plate will undergo quality inspection to ensure that it meets national standards and customer requirements.
