Zusammenfassung:	PURPOSE:To shorten the making time by laying steel-made form at the prescribed position in a tundish and throwing in castable refractory in the form. CONSTITUTION:The steel-made forms 5, 5a are set in the inner part of the tundish 1 as bringing these end part into closely contact with the inner face of the tundish to form the form space 6, and the castable refractory 7 mixing with refractory aggregate, inorganic binder and metallic powder for sintering is thrown in. After throwing the castable refractory 7 in, vibration or impact is given to it to tighten it. Next, it is preheated and the binder is melted to harden, and made to one body block. After that, the form is used to continuous casting as it is, and the metallic powder for sintering is melted and sintered by molten steel heat at the time of receiving the molten steel. By this sintering operation, the block is gradually progressed to sintering, and becomes to have enough resistance to the mechanical abrasion and impact, and also the form is melted down to turn into the molten steel.
