I got my second, Nichrome-based electric blast furnace up and running Minecraft/Gregtech 5u. I didn’t simply upgrade my original furnace, which would have been easier, because Titanium requires titanium tetrachloride, blast furnaces can only take one fluid input at a time, and I wanted to keep the oxygen input to my original furnace (gasses are considered “fluids”).
Starting my first run of titanium gave me a couple of small crises. My power plant wasn’t up to running ore processing, two 500 watt blast furnaces, the 480-watt chemical reactor making the titanium tetrachloride, and a vacuum freezer. This didn’t mean a shut down, since I have extensive battery power reserves, but it was clear those were going to get exhausted before the titanium run finished. I built an additional 512 watt diesel generator in a hurry before they ran out.
The second thing was I checked the output chest, and didn’t see any shiny new titanium ingots. Turns out I forgot to add a conveyor to the output pipe of the second furnace, so the hot ingots and magnesium chloride byproduct were stacking up there instead of moving to the freezer. Again, rush rush to make a conveyor and install it before the output filled up, because blast furnaces will merrily continue processing even if the output is full, and destroy things that are sitting in the output bus if it’s full.
Titanium’s another major milestone. It’s required for 2048-volt machinery, 128-volt electric hand tools (specifically, 128-volt drills), the mining laser, the distillation tower, the large (6000 watt multiblock) diesel generator, and probably other things I haven’t researched. The multi-block distillation tower’s probably the significant one, since it splits crude oil and cracked fuels into all the products at once, instead of one at a time like the single-block distilleries.
