A thermo-insulation article for a heat absorptive element, e.g., a water-cooled pipe, in a furnace has two parts joined to form a member for covering the pipe. Each part has an interconnected reticulated metal structure embedded in a refractory material. A thermo-insulating mat mounted over inner surface of the parts has a thermal conductivity lower, e.g., equal to or less than 25% lower, than thermal conductivity of the refractory material of the part. In one non-limiting embodiment of the invention, the thermo-insulating mat has a thermal conductivity equal to or less than 0.15 Btu's/hour/ft/degrees Fahrenheit, and the refractory material has a thermal conductivity in the range of 0.30-0.60 Btu's/hour/foot/degrees Fahrenheit. A surface of the mat is embedded in the refractory material and, optionally, a protective layer covers outer exposed surface of each of the mats to protect the mats during shipping and handling.
In a thermo-insulation article of the type for insulating a heat absorptive element in a heated chamber and having at least two parts adapted to be connected to form a heat insulating member for positioning about the element, each part comprising a metal structure in a refractory material, wherein a surface of the refractory material of the parts defined as an inner surface is designated to face the absorptive element, the improvement comprising:
A method of making a thermo-insulation article, comprising the steps of:
