ABSTRACT
Can one, after all this, invent without a theory?
Without S-Field analysis, without meticulous ASIP
operations, without all this difficult science? You can.
Here is a typical example.
Steel is poured into converters, huge metal crucibles
with an inside lining (facing) made of heat-resistant brick. Every 7 to 10 days the facing burns out, works has
to stop, the converter has to cool off, the lining has to
be broken out and renewed. The idea arose of changing the
crucible of the converter altogether. But the converter
is as a high as an eight-storey house; it is too
complicated to wheel out the crucible on rollers and then
put a new one in. What can be done? The inventor V.
