Maximizing Refractory Service Life
Thermal cycling, thermal shock, mechanical impact or vibration can all cause cracking, which in turn can lead to premature failure and substantial cost penalties. Achieving maximum refractory service life at a minimum cost is therefore a key element in the efficient operation of these processes, and in enabling companies to maximize their competitive edge.
Zhuzhou Sunshine New Material Technology Co.,Ltd is the refractory industry's No. 1 supplier of stainless steel fiber and is dedicated to product development and customer service.The Best Choice for Casting and GunningMelt Extract stainless fibers are fully annealed and therefore are more pliable and ductile. This is of particular benefit during the mixing cycle and when the refractory composite is installed.These pliable fibers are not only more user friendly than the stiff "needle-like" cut fibers, but also have better flow characteristics. Dispersion is further aided by the optimum Aspect Ratio design guaranteeing rapid fiber separation during the mixing phase.
The ability to install fiber reinforced refractory mixes by gunning is an important consideration in today's modern refractory industry. Melt extracted fibers are specified as a mandatory requirement by most international petrochemical companies where fiber containing mixes are routinely gunned inside large processing vessels and ductwork. During gunning, annealed RS fibers readily pass through the equipment with minimal additional wear.Cold drawn wire fibers can cause real problems. The "stiff, inflexible" fibers often bridge the ports and orifices in the gunning machine, with resulting blockages leading to expensive delays and wasted materials.50% Less Rebound Melt Extract steel fiber fiber also has a major influence on the cost of the sprayed linings. On impact with a sprayed surface, the majority of ductile fibers contained within a mix stay in place, whereas a high proportion of the stiff drawn wire fibers rebound, resulting in a very expensive waste material. Rebound loss of RS fibers is typically 50% less than that of drawn wire fibers.
