How to protect ASTM A572 Gr. 55 HSLA steel plates from oxide iron skin

It is easy to form oxide iron skin on the surface of ASTM A572 Gr. 55 HSLA steel plates surface. How to protect ASTM A572 Gr. 55 HSLA steel plates from oxide iron skin? It becomes a problem need to solve urgently.

There are some effecitive solutions for the oxide iron skin problem of ASTM A572 Gr. 55 HSLA steel plates that BBN steel would like to share:

First, in order to reduce the production of A572 Gr. 55 steel billets oxide iron skin in the heating furnace, we can reduce the heating temperature of ASTM A572 Gr. 55 HSLA steel billets.

Second, use the plate coil box as far as possible to improve quality of ASTM A572 Gr. 55 HSLA steel plates. The plate coil box can peel off the oxide iron skin generated in rough rolling area during the process of taking the middle ASTM A572 Gr. 55 HSLA steel billet.

Besides, the proper increasing of cooling water between the racks, and speeding up the rolling speed of ASTM A572 Gr. 55 HSLA steel plates can also inhibit the production of oxide iron skin.

BBN steel has been engaged in ASTM A572 Gr. 55 HSLA steel plates supply and exportation for many years. If you have any question about ASTM A572 Gr. 55 HSLA steel plates, welcome to discuss with us freely.
