There are new furnaces-
-size M (medium)- 3x3, speed=3
-size L (large)- 5x5, speed=10
-size B (blast furnace)- 7x7, speed=25 , I intend to change its mechanic later (mostly pollution handling)
New furnaces have 2 insert slots (I intended to make alloys, but it's does not work , and I left it that way, maybe one day it will work...) and 2 fuel slots

1st hour of marathon is soo painful, just waiting and crafting. So I made pneumatic assembly machine. It does not work as I wanted, I cannot force them to use liquid fuel (compressed air), so now it uses recipes with compressed air but also need 1 piece of fuel (it has 0.000000001W so it will last long), its annoying, but I cannot think about better solution. Its also bigger (5x5) and have speed of 1 so it will have usage in later game, but it can only produce simplest items- gear, cable and green circuit.

There is problem similar to trains- inserters are slow when they unload something from big buildings, so I wonder if I could do that furnaces could insert items on ground as miners? it does not seem to work, but maybe there are some tricks?

I changed smelting, so now to smelt iron plate (copper plate) you have to:
-smelt ore to pig iron (copper ingot)
-smelt it second time to make plates (because first you make clean metal and then you cast it to plates)

To make steel you no longer smelt it twice- its not how it works in real life. It should be mechanically formed (English definition seems to be wider though), but changing furnace to assembler would not be good idea. Instead I assumed that good steel= quenched steel, and to make steel you have to:
- take pig iron and quench it in assembler with water and it will make martensite (I assume that pig iron is still hot, no matter how long it waited in your pocket )
-temper martensite in furnace to get steel

To make good furnaces (and other items later) you will need creep resistant steel (its used in places with high temperatures). It should be made from iron and chromium or nickel, but i used copper instead, because I don't want to introduce new resources jet. That steel is made in furnace from creep resistant ore (5 iron plates + 1 copper plate).
