Net frame structure to prevent steel deformation measures

Net frame structure steel structure steel in rolling to prevent and reduce the deformation of the measures steel in rolling before the billet heating to rolling temperature, insulation for a certain period of time from the heating furnace to the rolling mill for rolling. In the heating furnace heating of the billet should be heated evenly and fully according to the process requirements, to avoid temperature differences, but also pay special attention to a certain period of time, so that the billet organisation is heated uniformly, so as to prevent the billet rolled into a steel after the production of internal stress.

Net frame structure steel in the process of storage and transport to prevent and reduce the deformation of the measures:

1. Steel in the process of storage and transport should be strengthened management.
2. Steel should be stored in a roofed warehouse during management; steel sections should be neatly palletised, and small steel pipes and sections should preferably be bundled and palletised with steel wires for storage.
3. Steel should be avoided to be forced to pull and lift from the pallet when lifting, and should be lifted when all steel is on the surface which can be lifted, and then lifted again with steel cable and special lifting tools tied securely. In the process of lifting, attention should be paid to the steel not to hit other heavy objects and buildings, so as not to cause steel impact deformation and other unsafe accidents.
