摘要

The flux-up device, a feeding hopper that temporarily stores flux; provided with; are arranged obliquely so that the tip positioned in the mold above the rear end is connected to the feeding hopper and the supply tube. And, there is a less than 3.0m and 0.5m more than the height H of up to the feeding hopper from molten steel surface of the mold 20; degrees or more minimum inclination angle α with respect to the horizontal direction of the tube supply said; θ is the angle of the virtual straight line connecting the outlet of the flux of the feeding hopper, and a lower position of the tip of the supply pipe forms with the horizontal direction, is 54.6 × H ^-0.5 degrees .
