Abstract
A lightweight cover provides heat insulation for a heated vessel such as a soaking pit. The cover can be readily assembled in a manner providing for ease of repair plus simplicity of maintenance. The cover has a pair of opposing frame members with ceramic fiber insulation positioned therebetween. The insulation is secured in movable engagement such as a free-floating and swinging engagement. In this mode, compression can be exerted against the insulation to most desirably reduce heat loss otherwise caused by heat induced ceramic fiber shrinkage. Moreover, with this structure a ceramic fiber heat seal can be achieved around edges of the soaking pit.
Claims12
A ceramic fiber insulation module adapted for repairing a shrinkage compensating insulation cover structure having a support frame supporting a matrix of discrete, folded ceramic fiber insulation units in form-stable condition, with said insulation being under externally applied compression while being linked, by means of insulation support means, in upwardly moveable as well as at least substantially swinging engagement with said support frame, said insulation module comprising:
- at least one unit of folded ceramic fiber insulation in form-stable condition;
- at least one support element in interengagement with said folded fiber unit within a fold thereof;
- first linking means securely fastened to said support element;
- and
- second linking means supportingly engaging said support element without being securely fastened thereto;
- wherein said first and second linking means protrude directly from said support element beyond the ceramic fiber and terminate therebeyond in a head configured for said moveable engagement with said support frame.
