robertsolo Posted April 26, 2018 Author Share Posted April 26, 2018 My numbers are from experence , even a thin liner can knock off the the top several hundred degrees , but as you go lower it gets harder and harder , like 2500-2000 is low hanging fruit , and 500- 200 is much harder to achieve . any theories ? ladle liners are usually oxides , remember fluorine will use oxides as Fuel . As to the different coefficients of expansion High conductivity is the way to fight that , carbon migration there are solid rocket nozzles (castor booster on the delta I think ) course that is very short duration but the shuttle boosters might accumulate some time maybe there was a study ?

robertsolo Posted April 26, 2018 Author Share Posted April 26, 2018 But with two material solution the temperature of the metal is lower , I thought we were talking about two material solutions now , in any case cold working the material is going to achieve necessary strength (at 1700 F ) I can tell you that with even testing it .

robertsolo Posted April 26, 2018 Author Share Posted April 26, 2018 I would really love to answer that question , but I think you are figuring it out already , I feel like those germans no mater how few clues you drop , someone will figure it out . I am jeopardizing my job at this point , sorry but I must stop . Link to comment Share on other sites More sharing options...
