Abstract
1. Фурма для донной продувки металла газами в ковше, содержащая металлическую гильзу с дном, заполненную огнеупорной массой, в которой выполнены щелевые каналы и индикатор износа в виде конуса, расположенный в верхней части нижней трети высоты фурмы, заформованный огнеупорной массой, отличающаяся тем, что в ней дополнительно выполнены лабиринтные каналы, расположенные между краем щелевых каналов и боковым краем фурмы, а индикатор износа в нижней части переходит в цилиндр меньшего диаметра, окруженный со всех сторон огнеупорной бетонной массой.2. Способ изготовления продувочной фурмы, включающий в себя изготовление конусной гильзы с дном и газоподводящей трубкой, установку в ней каналообразующих полосок и сетки для образования сквозных щелевых и лабиринтных каналов и индикатора износа, фиксацию нижних концов каналообразующих полосок и сетки с помощью расходуемого шаблона, а верхних концов с помощью фиксатора, надетого на верхнюю часть конусной гильзы фурмы, послойную укладку и виброуплотнение бетонной массы с последующей термообработкой, отличающийся тем, что крепление индикатора износа осуществляют с помощью двух скоб из тонколистового металла и резьбовых шпилек, при этом одну из скоб устанавливают в верхней конусной части индикатора, а вторую - на нижнюю цилиндрическую часть индикатора.1. A lance for bottom blowing metal gases in a bucket, containing a metal sleeve with a bottom filled with a refractory mass, in which slotted channels are made and a wear indicator in the form of a cone located in the upper part of the lower third of the height of the lance, molded with a refractory mass, characterized in that it additionally has labyrinth channels located between the edge of the slotted channels and the lateral edge of the lance, and the wear indicator in the lower part passes into a cylinder of smaller diameter, surrounded on all sides by a refractory concrete m assoy. 2. A method of manufacturing a blowing lance, including the manufacture of a conical sleeve with a bottom and a gas supply tube, installing channel forming strips and a mesh therein to form through slotted and labyrinth channels and a wear indicator, fixing the lower ends of the channel forming strips and mesh using an expendable template, and the upper ends using a latch worn on the upper part of the conical sleeve of the lance, layering and vibration compaction of the concrete mass with subsequent heat treatment, characterized in that the indicator mount Wear torus is carried out by means of two brackets of sheet metal and threaded rods, wherein one of the brackets mounted on the upper conical part of the indicator, and the second - on the lower cylindrical portion of the indicator.
