Steel smelting Mk. II compact

Steel smelting Mk. II. comapct and upgradable. There is an starter module and a module with two lines of steel smelting to upgrade. The belts and pipes only connect when the blueprints are used for expansions. When copy-past from already built structures some pipes and belts don't connect. But it is possible to add a module from the blueprint to a already built structure.

The two pipes coming out next to the steel storage are meant to provide smoke to an exhaust scrubber. But they don't need to be connected necessarily.

At some point there's a need to ugrade the belts to Mk. III.

I will be upgradable with my steel arcfurnace build.
