The blowpipe is used to transmit hot blast air in blast furnace operation, which is continually manipulated and part of a high-temperature and high-pressure environment. In order to optimize blowpipe functionality and reliability, computational fluid dynamics (CFD) was applied to simulate the flow pattern of hot blast air, to generate details of input conditions for mechanical simulation of thermal stress, and to help identify areas of failure corresponding to high stresses and plastic strain. In this investigation, parametric studies were conducted to study the effects of thermal paper thickness, thermal paper length, and refractory thickness on the thermal and stress distributions. The results of this investigation can offer useful information for new blowpipe designs with reduced failure and better reliability.

AbstractIn order to realize comprehensive and massive treatment of boron mud secondary resource, fundamental study on boron mud applied to oxidized pellets production as additive was carried out in the paper under laboratory conditions. The effects of boron mud on the performance of oxidized pellets were investigated systemically, and boron mud was combined with other boron-rich material innovatively. The results showed that, within certain limits, boron mud can improve properties of oxidized pellets. The bentonite content decreased to 0.3 % when adding 1.0 % boron mud additive and the pellets met blast furnace requirements. With the combination additive content 0.8 %, bentonite content can be further decreased to 0.2 %, and the pellets properties were better than base pellet. Therefore, it was an effective way to reduce environmental pollution and optimize blast furnace operation by developing boron mud secondary resource as pellets additive.
