It is proposed that heat losses from steel in pouring ladles be reduced by decreasing the diameter of the top part of the ladle based on a theoretical estimate of the projected loss reduction. It was determined that a 10% decrease in the diameter of the top of a 350-ton-capacity ladle would lower heat losses from steel in the ladle by 12%. The proposed ladle redesign would also reduce expenditures on electric power for preheating steel on ladle-furnaces prior to its casting.
