摘要： PURPOSE:To prevent the solidification of a molten metal around an upper nozzle to be exchanged of a vessel contg. the molten metal and the remaining of the molten metal in said vessel and to discharge the whole molten metal by adjusting the length of the upper nozzle to approximately the same level as the level of the eroded laying brick and the remaining surface of a tuyere. CONSTITUTION:The position at the top end of the upper nozzle 1 is made approximately equal to the top surface of the laying brick 4 and the tuyere 3, by which the remaining and solidification of the molten metal around a plug 1 are obviated. The upper nozzle 2 having the short length is used when the position of the top surface of the brick 4 and the tuyere 3 lowers due to eroding. The upper nozzles 2 having stepwise different lengths are therefore prepd. and are properly exchanged according to the eroding condition. The plug 1 is fitted and mounted to the upper nozzle 2 prior to fitting and mounting of the nozzle 2 into the tuyere 2 then the nozzle 2 is inserted into the tuyere 3 and is thereby fitted and mounted therein in order to avoid the mounting of the plug 1 in the vessel contg. the molten metal.
摘要翻译：目的：防止上部喷嘴周围的熔融金属凝固，以更换容器。熔融金属和剩余的熔融金属，并通过将上部喷嘴的长度调节到与侵蚀的铺设砖的水平和风口的剩余表面大致相同的水平来排出整个熔融金属。构成：上喷嘴1顶端的位置大致等于铺设砖4和风口3的上表面，从而消除了塞子1周围熔融金属的剩余和凝固。当砖4的顶面和风口3的位置由于侵蚀而降低时，使用长度较短的上喷嘴2。因此，制作具有逐步不同长度的上喷嘴2。并根据侵蚀条件进行适当的交换。在将喷嘴2装配到风口2中之前，将插头1安装到上喷嘴2上，然后将喷嘴2插入风口3中，从而将其安装并安装在其中，以避免安装插塞1在容器中熔融金属。

摘要： PURPOSE:To close and mount surely only the plug into the outflow hole in the base of a vessel without the need for cooling the vessel for a molten metal by mounting refractories to the outside peripheral surface in the lower part of the plug and pressing the same atop the nozzle brick forming said outflow hole thereby pressurizing the refractories. CONSTITUTION:The top end of a metallic pipe 3 is pressed onto the nozzle brick 6 or tuyere brick 7 so as to be made concentrical with the outflow hole 1. The refractory plug 2 is fixed by a support 4 to the inside of the pipe 3 and the castable refractories 5 are packed to the outside periphery in the lower part of the plug 2 according to the eroded condition of the brick 6. The support 4 is lowered by the pressure from a supporting bar 9 by which the refractory plug 2 and the refractories 5 are integrally closed and mounted into the tuyere 12 of the hole 1.
摘要翻译：目的：仅将插头安装在容器底部的流出孔中，而不需要通过将耐火材料安装到插头下部的外周表面并将其压紧，从而不需要冷却熔融金属容器在形成所述流出孔的喷嘴砖的顶部，从而对耐火材料加压。构成：将金属管3的顶端按压到喷嘴砖6或风口砖7上，使其与流出孔1同心。耐火栓2通过支撑件4固定在管3的内部并且根据砖6的侵蚀状态，浇注耐火材料5被填充到塞子2的下部的外周。支撑体4通过来自支撑杆9的压力降低，支撑杆9通过该压力使耐火材料塞2和耐火材料5一体封闭并安装在孔1的风口12中。

摘要： PURPOSE:To open smoothly and easily a closing plug in the stage of lifting said plug and discharging a molten metal from an outflow hole by forming said plug of refractories having the coefft. of thermal expansion of prescribed times the coefft. of thermal expansion of the surface of the outflow hole in contact with the plug. CONSTITUTION:The closing plug 7 to be fitted into the molten metal outflow hole formed of tuyeres 2, 8 and an upper nozzle 1 is made into the constitution in which said plug is lifted from the lower side of the plug 7 by a lifting mechamism to discharge the molten metal through the hole opened in such a manner. The refractories having the coefft. of thermal expansion made 0.6-1.0 times the coefft. of thermal expansion of the surface of the abovementioned outflow hole in contact with the plug 7 are used for the plug 7. The closing plug of the outflow hole is thus smoothly and easily opened and the breakdown of the closing plug is obviated.

摘要： PURPOSE:To open easily a closing plug in contact with the outflow hole in the bottom of a vessel for contg. a molten metal so that the outflow of the metal is made sure by the constitution in which the outside flank of the plug has a taper of a prescribed angle or above upward and outward relative to the vertical center line of the outflow hole. CONSTITUTION:This invention relates to the colsing plug 7 which fits into the molten metal outflow hole formed of tuyeres 2, 8 and an upper nozzle 1. The outside flank of the plug 7 in contact with the outflow hole is formed to the taper having an angle of >=10 deg. upward and outward relative to the vertical center line of the outflow hole. The lifting distance S of a lifting mechanism consisting of a cylinder 9 and a piston 10 is set in an S>2.0H (h; the vertical height of the contact surface) range in the stage of opening the plug 7 from the lower part by using said lifting mechanism. The opening of the closing plug and the outflow hole is thus made easy and the outflow of the metal is made sure.
