IRS0 i i. r. aricp V. M. Kadlpine - Research Cutr. Refractory 4 Insulating Rafractc*y Products Reesarch Revise 7/13/62 Action Shut #11 - Bated 7A6/62 It has been request "hat an evaluation b* node of the 29 nar product suggestions eubsitiul at the Research Revise of 7/13/62 together with specific recaanand'/iiona, (1) It la meexsaeoded that a Research objective type SIR be leaned to explore the possibilities of developing a light weight gunning and rartrM- alx tf.fch the folloeiag approximate properties! Tecperctire limit - 2000 F minimi*. Weight ;fter firing - 15-30 lie. per cubic foot. Conprevjiva strength - 55 at 20 pal at all temperatures. 3hrln?7e - .55 at 2000 F Coodraiivity - 1.0 at 1000 F naan. Apprriaate aelling price - 1200.00 per ton wtrlwnw. Such a product would have applications in high temperature duct linings, heal treating furnaces, hot blast meins, furnace doors, controlled cooling furnaces, etc. The eetlnated national sales potential in these appHcactioic would be in eposes of 11,000,000 per year and we believe we could obt tin at least 255 of thin potential within the first year after develppsett* To our knowledge there ia no existing material cn the sadcst having lu'eperties approaching those Hated above which would plane uv in the positlat of being first in tbs field with this camnodlty. Msteri/Aa currently baiig need and which ww would expect to displace with this nOBBOdity would bej competitive insul sting fire brick, competitive refractory ceetebles end gunning nixes, competitive block insulations, and beery firebrick. (2) It Is reresnended that a Research objective type SIR be issued to explore tbs prasihllltlea of developing TnamieMng Fire Bride in ill tasperoture ranges pith truces or nc reducible addee. The Varteo Oanpany, Carborundum Cc*pany, a. P. Qreen Company, and dasroek Coepany are currently producing such materials and selling then at unusually high prices, One of the knexn usages for pro:-note of this type ia for refractory office in the bright einoaling of stainless steal. This single market Is eetlnated at being in tl* order of 1300,000 per year, ia part of tbs exploration in t/iis ares, considerat ion sight be given to the development of high purity Itsol in days as obtaine/i from dcaestic sources as well as Iran overseas. -2- O' An SFR has boon issued to explore the pest bility of developing an air setting cefient for bonding btriok in eoltan aluminum Berries. (U) in SHI has been issued to develop an TiwnitMwg Fire Brlek to neet Military Specification HIL-B-16008 B. (?) It Is recoeennded that a study he initiated in the following fields to dstezolne present practices, problems, and market potential prior to the issuance of fareal SHI1at a.- Hot Metal Mixers - 1 bonding cement superior to those currently in coea&en usage is required in this field. b. - Iron Malting Cupolas - A superior and inexpensive material is needed for patching the linings of the pelting zone where the refractories are ennaimed rapidly. c.- Ladle lining* - Development of a mqjerior refractory for lining ferrous and non-ferrous ladles to replace the clays In comuut usage merita study. d.- Castable Refractory For Lining Hot Tope - Seme sills are using castable refractories in large tonnages for use as the lining in their hot tope. Along with our development of consumable hot tops, the use of a castable refractory should be investigated. e .-A Last Furnace linings - Large tonnages of gun type refractories are currently being used for patching blast furnace linings. This field should be thoroughly explored~vlth the ala of developing a superior product for the Servian. G. E. Grisshav S. E. Vooley GEBilsr eet J. B. Jobe T. H. Eaton I. W. Burleson E. F. Briggs D.
