POSECQ, INC. INTER-COMPANY AND INTER-DEPARTMENTAL CORRESPONDENCE / > TO: T. R. Bernard! from: j. t. Vrh DATE: April 2, 1974 subject: s cr ap/Pr oduc t ion March, 1974 I. One-oiece - Area 08 Pieces produced Pieces scrapped Scrap Rate Scrap Rate (February) 16,348 310 1.9% 3.1% The primary reduction in scrap can be attributed to the x following: \ a. a decrease in burnt tops, better oven controls. b. a reduction in floor breakage as to the high volume of sales, tops were packaged onto shipping racks rather than floor stored. c. better quality of surfactant RX1281 which improved forming. Trials were again attempted with non-asbestos formulations in the production of 390 tops for Wisconsin Steel. Tops pro duced from Proflex EP5484 again ran with a scrap rate of 20%, mainly due to thickness in consistencies as the product formed was extremely lumpy. Tops would not fit castings. A. Santighian then attempted to produce the 390 tops in Proflex EP5492. The tops produced from this formulation were much smoother and the finished product did fit the casting. A longer trial run will be attempted when RM X3588 (fiber) can be sent to Chicago. Repairs of 538M dryers continued throughout the month. At this time, 95% of the dryers in use are in good shape. 2829 -2- D epartaent 114 A) Rings Pieces produced Pieces scrapped Scrap rate Scrap rate (February) 9477 422 4.5% 4.6% The scrap rate on Proflex rings maintained the same level as in February. Undercuring is still the major problem here. B) Multiple Profax Pieces produced Pieces scrapped Scrap rate Scfap rate (February) 54,667 2,761 5.0% 10.4% The scrap level for the production of multiple Profax and Pro flex fell sharply as slurry problems were eliminated through proper handling of slurry changes. At no time was Proflex allowed to run more than four consecutive machine shifts. This action prevented oil RM X1281 build up in the water. The scrap causes during the month were primarily caused by burning of Proflex boards and malformed Proflex boards due to tool screen plugging. Since the addition of the new tool table it may now be poss ible to change screens when slurry changes are made without extreme delays in production time. III. Department 110 Product Koron 200 Koron 160 Koron 205 Ceramol 55/80 Ceramol 55/90 Ceramol 660/90 Moldcote EP1677A Dexel 60 Batches Produced 43 21 5 2 1 3 10 2830 -3- Of the batches produced, all vere found to be satisfactory from initial testing. However, the thw batches of Ceramol 55/90, when reaching the customer, were found to be settled out and not usable. The problem here cannot be answered properly at this time. However, it is quite possible that the problem lies with the RM 117 used or with the RM 66 used. This statement is made as Cleveland manufacture had a similar problem when using a certain grade RM 117. The RM 66 problem, though, could be one of water content as this material which was not pure but a reclaimed material did contain 5-6% water which may have caused a problem with the suspension properties.
