Centrifugally Cast Stainless Steel Fiber-Reinforced Refractory Pipe

  • Description:
    This research was initiated to develop a self-supporting ceramic pipe for use in coal gasification systems. Ideally, the pipe would be impermeable and strong enough to replace steel pipe that is susceptible to corrosion by acidic species in the product gas. However, a more reasonable objective would be a pressurized shell, but the liner must have properties superior to those of castable refractories now used for this application. This program demonstrated that 3-inch-id pipes can be fabricated from a stainless- steel-fiber-reinforced refractory castable mix by centrifugal casting. Although it is possible to obtain some degree of preferential fiber orientation by introducing the fibers and castable separately, this procedure is complicated in that (1) multiple batches of fibers must be weighed out for each pipe; (2) alternative additions of fibers and castable are time consuming, requiring almost twice the fabrication time needed with a preblended mix; and (3) fiber feed rates are hard to control.
