Abstract 1. In a method of applying low slump refractory material to form an insulating covering on a length of substantially horizontal skid rail cooling pipe having anchoring structure projecting therefrom, the molding of a first section of refractory material in situ around a lower portion of predetermined length of said cooling pipe in surrounding relation to at least a portion of said anchoring structure including the steps of taking a substantially rigid form having a trough, layering a sheet of flexible material against the upper face of said trough, placing the refractory material mix in said trough, advancing said form toward said length of cooling pipe to bring the refractory material mix into engagement with said portion of said anchoring structure, vibrating said from at relatively high speed to permit said form to be easily moved toward said length of cooling pipe and to cause said refractory material mix to completely surround said portion of said anchoring structure, moving said form toward said length of pipe until the refractory material mix is engaged therewith, securing said sheet to said length of cooling pipe, and removing said from whereby said refractory material mix is permitted to continue to harden while held by said sheet, whereby all of the aforementioned steps may be repeated on adjacent lengths of cooling pipe using said form.
