1.Reliable transfer of hot blast to the tuyeres
2.Energy efficient design reduces thermal loss, lowering shell temperatures and increasing hot blast temperature
3.The proportion of refractory materials can be adjusted appropriately as per specific hot blast temperature, blast pressure and oxygen enrichment
4.Compensates for the differential expansion of the blast furnace shell and bustle main
5.Unique external tie-bar design controlling the length during thermal expansion
6.Increasing gas tightness in the hot condition
7.Freedom of movement at elevated temperatures, reducing the potential for   ‘hot spots’
8.“Quick-drop” elbow and blowpipe for tuyere maintenance access
9.Suitable for multiple fuel lances
10.Blast flow measurement
11.Supplied  “ready to install”
