波兰的累格尼察铜厂与格沃古夫铜厂,使用一种新的、自动风动捅风口机,可使转炉达到最高产(旦力)并提高硫的回收率。累格尼察铜厂设置了33吨及45吨虹吸式转炉,格沃古夫铜厂设置了80吨虹吸式转炉,在这些转炉中使用一种新式捅风口机可在相当小的空间内进行操作。捅风口机的装设直接关系到70年代初期 The Tieggenica copper plant in Poland and the Geovog copper plant in Poland used a new, automatic pneumatic pneumatically operated tuyere to reach the highest yield (denier) and increase sulfur recovery. The 33-tonne and 45-ton siphon converters are installed at the Turgunica copper plant and the 80-ton siphon converter is installed at the Gorganogov copper plant, where a new type of poke tuyere can be used in a relatively small amount of space operating. Poke tuner installation directly related to the early 70s
