PURPOSE:To provide a titled continuos casting device which can prevent metal penetration between side dams and water cooled drums by packing a powder mixture of graphite and glass powder or the like into the U-shaped channel which is formed with the side dams and the surfaces of the water cooled drums and is opened on the molten metal side. CONSTITUTION:A U-shaped groove having an opening on a molten pool 7 side is formed in the notched part of the part where a pair of refractory and heat resistant stationary side dams 4' contact with water cooled drums 3, 3'. A powder mixture 16 of graphite and glass powder or molten glass is supplied from a supply tank 12 through the groove 14 of a guide 13 into said channel. In other words, the powder 16, etc. are carried in accordance with the rotation of the drums 3, 3'. Here, 22 is a removing device of the foreign matter stuck on the drums 3, 3', and 28 is a part for releasing the powder 16, the molten liquid and the molten glass thereof. The metal penetration between the side drums and the water cooled drums is prevented and the formation of the solidified shell in the contact part between both is prevented or even if said shell is formed, the formation is suppressed to the extent posing no problems and the always stable operation is accomplished by using the above-mentioned continuous casting device for a thin metallic plate. |
