Q295NH weathering steel plate manufacturing process

When the minimum yield strength of Q295NH weathering steel plate is 295Mpa, the tensile strength is between 430-560Mpa. Q295NH weathering steel plate is mainly used to produce trucks, containers, buildings, towers and some structural parts for atmospheric corrosion protection.

Q295NH weathering steel plate generally adopts the process route of refined material entering the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting-controlled rolling and controlled cooling. During smelting, scrap steel is added with the charge The furnace is smelted according to the conventional process. After the Q295NH weathering steel plate is tapped, deoxidizers and alloys are added. After the molten steel is treated by argon blowing, it is cast immediately. The molten steel after argon blowing and temperature adjustment is cast into a slab by a continuous casting machine. By adding rare earth elements, Q295NH weathering steel plate is purified, and the content of inclusions is greatly reduced.
