Abstract: PURPOSE:To effect a specified aeration performance from the initial stage of operating apparatus by supplying an aeration gas from the gas phase side of a gas permeable membrane and filling at least the gas phase side with the gas before liquid to be treated is passed on the liquid phase side of the membrane. CONSTITUTION:An aeration gas is supplied continuously on the gas phase side 10b of a gas permeable membrane 11 before liquid to be treated is passed on the liquid phase side 10a of the membrane 11.

From the difference in the partial pressure ratios of the gas between the liquid phase 10a of the module 10 and the gas phase 10b, a gas to be removed in the liquid to the treated moves from the liquid phase side 10a to the gas phase side 10b through the gas permeable membrane 11, while the aeration gas moves to the liquid phase side 10a, so that the gas to be removed is eliminated from the liquid to be treated. In this way, a gas other than the aeration gas is prevented from transferring to the liquid to be treated through the gas permeable membrane in the initial stage of the aeration treatment.

Abstract: PURPOSE:To prevent the bulging phenomenon and the breakout phenomenon of a brittle part by surrounding the peripheral wall of a cast slab with a cooling chamber formed with air-tight state and enabling cooling in a secondary cooling zone and pressurizing in the cooling chamber with gas. CONSTITUTION:The cast slab 6 is continuously drawn out of a mold 4 and cooled in the cooling chamber 11 of the secondary cooling zone. The cooling chamber 11 is connected with plural steps and a through-hole 11d-11g for cast slab in each of the cooling chambers 11a-11c are kept to practically air-tight with the cast slab 6. A pressure sensor 14a fitted to the cooling chamber 11a measures the pressure in the cooling chamber 11a and this measured pressure is transmitted to a control device 14d. The control device 14d adjusts the opening degrees of a flow rate adjusting valves 14b and a leak valve 14c so that the pressure in the cooling chamber 11a equals the static pressure of the molten steel at the intermediate point of the cooling chamber 11. As the expanding action of the solidified shell in the cast slab caused by the static pressure of the molten steel cancels out with atmospheric pressure in the cooling chamber 11, the bulging phenomenon is not developed.
