The manufacturing process and normalizing technology of ABS EH32 shipbuilding steel plates

The manufacturing process and normalizing technology of ABS EH32 shipbuilding steel plates are the 2 topics we will discuss:

1. The manufacturing process of ABS EH32 shipbuilding steel plates:
BF, hot metal pre-desulfurization, LF refining and smelting, RH refining slab continuous casting, cutting, storage, billet heating, four-roll reversible rolling, laminar cooling, straightening, finishing, surface blast test flash ball heat treatment, air cooling, inspection, identification, storage.

2. The Normalizing Technology of ABS EH32 shipbuilding steel plates:
Heating temperature is designed according to Ac3 + (50-100 degrees Celsius), ABS EH32 steel plates normalizing temperature control three parts: preheating temperature is 860 degrees Celsius, heating temperature (920 + 10) degrees Celsius, average heating temperature (910 + 10) degrees Celsius. Heating rate is 115-210 minutes / mm, including heating and soaking time. After normalizing, air is below 200 C.

The manufacturing process and normalizing technology of ABS EH32 shipbuilding steel plates are as above. For more information, please contact BBN steel freely.
