Have you ever wondered how hot it gets in a furnace melting cast iron? Have a look at my video Here is another video about making a cast iron flywheel for a model steam engine ironman |

What do you use to measure the furnace temperature with? I've seen thermocouples that go to 1100oC, but nothing that will do 1600oC, and my Google powers are weak today... |

I've just found Tungsten Rhenium T/Cs which can go up to an amazing 2300oC! http://www.thermocoax.com/doc-Temperature_sensors/E201-0_Thermocouple_C.pdf Cheers. Phil. |

So - next challenge for Rob 'the miracle worker' Wilson - can you come up with a suitable rig (chrome plated of course) so we can all make our own? Dave |
| AdeV:
Phil - have you seen the price of those things? I've only found 1400oC thermocouples on general sale, and they come in at between £300 and £3500 depending on length & thickness (oo-err). Makes the £28 I paid for a K-type 1100oC one seem quite reasonable... |
