Abstract

1. Способ кладки футеровки сталеразливочного ковша предусматривающий последовательную многоступенчатую кладку огнеупорного кирпича по высоте ковша, отличающийся тем, что кладку рабочего слоя футеровки ковша ведут с утолщением по высоте ковша к днищу, которое увеличивают с учетом среднего времени нахождения стали в ковше и времени взаимодействия расплава в том числе шлака с футеровкой, при этом кладку ведут с учетом следующих пропорций: hутолщенного рабочего слоя нижней части ковша составляет 0,2-0,5 высоты Н, его толщина δравна 1,4 толщины δрабочего слоя, а высота hутолщенного рабочего слоя средней части ковша составляет 0,15-0,3 высоты Н ковша, при ее толщине δ, равной 1,25 толщины δрабочего слоя, а верхний ряд кирпичей, под металлической обечайкой ковша, устанавливают на торец к дну ковша и ребром вплотную к арматурному слою футеровки ковша, причем футеровку рабочего слоя стен ковша, кроме верхнего ряда, укладывают на плашку относительно дна ковша, а рабочий слой днища ковша укладывают кирпичом на ребро к дну ковша, и плашкой к стене ковша.2. Сталеразливочный ковш включает металлический корпус и последовательно расположенные в нем арматурный и рабочий слои футеровки стен и днища ковша, а также гнездовой кирпич с разливочным стаканом, установленным в днище ковша, отличающийся тем, что рабочий слой выполнен с утолщением по высоте к днищу ковша с учетом следующих пропорций: hутолщенного рабочего слоя нижней части ковша составляет 0,2-0,5 высоты Н, его толщина δравна 1,4 толщины δрабочего слоя, а высота hутолщенного рабочего слоя средней части ковша составляет 0,15-0,3 высоты Н ковша, при ее толщине δравной 1,25 толщины δрабочего с1. The method of laying the lining of the steel pouring ladle, which involves sequential multi-stage laying of refractory brick along the height of the ladle, characterized in that the masonry of the working layer of the ladle lining is thickened along the height of the ladle to the bottom, which is increased taking into account the average time the steel was in the ladle and the melt interaction time in including slag with a lining, while the masonry is carried out taking into account the following proportions: the thickened working layer of the lower part of the bucket is 0.2-0.5 height H, its thickness δ is equal to 1.4 thickness working layer, and the height of the thickened working layer of the middle part of the bucket is 0.15-0.3 of the height H of the bucket, with its thickness δ equal to 1.25 of the thickness δ of the working layer, and the upper row of bricks, under the metal shell of the bucket, is installed on the end face the bottom of the bucket and with the edge close to the reinforcing layer of the bucket lining, and the lining of the working layer of the bucket walls, except for the upper row, is laid on a die relative to the bottom of the bucket, and the working layer of the bottom of the bucket is laid with a brick on the edge to the bottom of the bucket, and a die to the wall of the bucket. 2. The steel pouring ladle includes a metal case and the reinforcing and working layers of the walls and the bottom of the bucket lining successively located therein, as well as a nesting brick with a casting cup installed in the bottom of the bucket, characterized in that the working layer is thickened in height to the bottom of the bucket, taking into account the following proportions: h of the thickened working layer of the lower part of the bucket is 0.2-0.5 height H, its thickness δ is equal to 1.4 thickness δ of the working layer, and the height of the thickened working layer of the middle part of the bucket is 0.15-0.3 height H of the bucket,its thickness δ is equal to 1.25 of the thickness δ of the worker with

Claims
