ASTM A387 Gr91 Sheets, Plates, Coils Manufacturing Process

Reheating Furnace

A reheating furnace is a crucial component in the steel manufacturing process, particularly for hot rolling mills where sheets or slabs are heated prior to rolling.

Scale Breaker

A scale breaker, also known as a descaler, is a piece of equipment used in the steel manufacturing process to remove scale from the surface of hot-rolled steel products. Scale refers to the iron oxide layer that forms on the surface of steel when it is heated to high temperatures during the manufacturing process.

Finish Rolling

Finish rolling, also known as final rolling, is the last stage in the hot rolling process of steel or other metals. It involves reducing the thickness of the material to its final desired dimensions and achieving the required surface finish.

Skin Pass Mill

A skin pass mill, also known as a temper mill or a rolling mill, is a specialized type of rolling mill used in the steel or metal industry to improve the surface finish and mechanical properties of cold-rolled steel coils or sheets. It operates after the cold rolling process and before further processing or coating.
