In the previous report (Tetsu-to-Hagané, 45 (1959) 12, p. 1341), experiments were carried out on effects of the primary cooling, in other words cooling of billets in molds, and on the surface of billets. The importance of setting the primary cooling under the optimum conditions were confirmed.
In this report, at first the mechanism of the primary cooling is considered, and then effects of some factors on the primary cooling are investigated experimentally. Experimental results are summarized as follows.
Majority of the primary cooling is conducted by heat transfer from the surface of the billetto the mold cooling water through the mold wall.
Main factors influencing the primary cooling are the casting speed of the billet and the time of the use of a mold.
On the other hand, the casting temperature and the quality of steel only slightly influence the primary cooling.
Basic data obtained from these experiments presumably have a great meaning in considering the ideal primary cooling later.
