Going to Keldagrim for the first time.

Although level 30 Smithing is required to smith steel bars, level 60 is strongly recommended so that you don't have to pay an entrance fee to the Blast Furnace. It provides a great opportunity for players to reap great profits by producing a large volume of steel bars (worth 473 each), which are coveted by low-to-mid level smiths.

Depending on your level of activity, you can produce between 3,000 and 4,600 steel bars in an hour. That means the profit margin falls between 289,125 and 509,925 hourly.

First make sure you are on either world 352, 358, 386 or 387 (the official Blast Furnace worlds). After purchasing the raw materials, deposit 72,000 coins into the coffer. This will allow you to use the furnace without having to worry about operating it. It will remove 1,200 coins every minute automatically for a total of an hour. Then, start by placing iron ore on the conveyor belt first, then emptying your coal bag of coal and deposting that right after. Then retrieve your bars from the bar dispenser by clicking on it (if ice gloves are equipped) or dousing it with a bucket of water and then collecting the bars. Repeat this process until you either run out of ore, or the coffer is empty.
