jfe cold rolled steel high temperature atmosphere

CVD process. Concretely, after rolling low Si steel, which can be cold rolled, to obtain the required thin gauge thickness, heating is performed in a non oxidizing atmosphere, and SiCl. 4. gas is blown to the both back and front sides of the steel sheet under that high temperature environment. This causes a substitution reaction between

Steel plates for low temperature use Abrasion resistant steel plates Stainless steel plates and clad steel plates, etc. JFE Steel has adopted powerful rolling machines for controlled rolling and highly efficient on line accelerated cooling facilities for manufacturing proprietary high performance steel plates.

We recently discussed how hot rolled steel is made. Now it only makes sense we talk about cold rolled. Cold rolled is the next step along the line of flat rolled steel products. The process starts with hot rolled P&O. Hot rolled is processed to a final thickness that is heavier than most sheet products.

Grain oriented electrical steels (GOES) are iron silicon alloys that were developed to provide the low core loss and high permeability required for efficient and economical electrical transformers. GOES is the most energy efficient electrical steel and used in transformers where energy conservation is critical.

Steel material hardens after cold rolling due to the dislocation tangling generated by plastic deformation. Annealing is therefore carried out to soften the material. but the three patterns shown in the figure are typical. For cold rolled strips for general use, in addition to a high level of automatic temperature and atmosphere control
