E13-3 - Low Cost X Factor Equipment. Ro progress to report. 7. EU-8 - Model of American Arch Light Veight Insulating Refractory call. \ 8. Pl-A This model -.as started on June 26 1 27th but K. T. Deris and R. V, Higgins made design.revisions during erection ta^facilitate construct ion permit various wall thicknesses using from Ay to 9" of insulating firebrick. We axe now going to finish the model using 4^ and 9* depth tile along with the present >>5/4" shapes. The overlap on the H315 tile by the insulating firebrick was decreased so that it would cot interfere vita the castings or hangers which support the K315 tile. Karl Davis is working up the new design drawing-5 on the besis of the model revision. .. - Block Insulation Research. coking. received one complaint on this and to keep it frcm happening again the following steps are to be taken. 1. burnish hot plate to ovu tender and test a larger number of samples for sl. king as they come from the oven. 2. Work cu inorganic binds:-. 3. Try to eliminate asbestc : from block# 4. Set manufacturing specif `.cations for plant# 3. "I. *V. Hacdlcabiliiy To: iting. 1. Brop taster - So action due to vacation shut down of plant. 2. Tumbler test - We di3cuasod this proposed specification and okayed it from our point of view*, tfe have the' equipment for this test. C.
