Problems solved by technology

[0008] However, when the size of the inclusions in molten steel is less than or equal to 30 μm, it takes longer for the inclusions to float than for the molten steel to stay in the tundish
Therefore, it is difficult to remove inclusions with a size of 30 μm or smaller using the dam and weir of the tundish

Abstract

The present invention provides a melt treating apparatus and a melt treating method applied thereto, the apparatus comprising: a container having a melt injection part arranged at an upper portion thereof and a hole formed through a bottom portion thereof; an induction member installed to be spaced from the melt injection part to a hole side; a gas injection part installed on a bottom portion while being spaced from the induction member to a melt injection part side; and a chamber part extending in a widthwise direction, with the inside thereof open downward, and being arranged on an upper portion of the container so as to face the induction member and the gas injection part. In treating the melt, the induction member and the gas injection part are used to form a rotating current of the melt, and the rotating current can be used to effectively remove an inclusion.

Description

technical field [0001] The present disclosure relates to melt processing apparatus and melt processing methods. More particularly, the present disclosure relates to a melt processing device capable of effectively removing inclusions and a melt processing method using the same. Background technique [0002] In the field of steelmaking, continuous casting methods are superior to conventional ingot manufacturing methods in terms of quality uniformity and recovery. Therefore, many researches and developments have been conducted on operating equipment, techniques, etc. of the continuous casting method. As a result, almost all steel grades, including high-alloy steels, can be produced by continuous casting methods, except for a few special applications. Operating equipment for the continuous casting method includes continuous casting equipment. [0003] Continuous casting facilities are facilities for producing slabs using refined molten steel supplied from steelmaking faciliti...
