Abstract
The invention concerns the production of steels which have an isotropic structure, are very well adapted to cold forming particularly by pressing and which have a very low silicon content. The method comprises taking a deoxidated liquid steel with a low silicon content and placing in it a cored wire containing a divided material, which is a mixture of silico-calcium and granular calcium in a specific quantity and specific proportions. The method is applicable to non-alloyed or slightly alloyed steels and is particularly suitable for a continuous casting installation.
