Your ideas sound pretty good, but it's difficult for any one person to know the complete operation, from raw materials to finished coils. Your best bet is to get a copy of Dean Freytag's book, or have a look at the book that I mentioned. The pictures will give you way more info than a dozen of us typing until our fingers bleed.
Some answers: A coke oven battery consists of a number (could be a couple hundred) of coke ovens, with "doors" on both sides, and charging holes in the top. Running on rails along the top is the charging car, or larry. It lifts the lids on the charging holes, then drops a charge of coal into the oven below, then reseals the lids. When an oven is ready to be "pushed" (the coal has been turned into coke), the pusher, a large, usually electrically-powered device, running on rails along one side of the battery, will move into position and remove the door on the side of the oven to be "pushed". At the same time, another machine on the other side of the battery, also electrically powered and running on rails, "extracts" the door on the "coke" side of the oven, then moves it out of the way, while at the same time lining up a "coke guide" with the open oven. On an adjacent track is the quench car. (By the way, all of these "tracks" mentioned are a wider gauge than a railroad track - sometimes as much as 20' or 30'.) The pusher inserts a ram into the oven and pushes the coke out the open door on the opposite side of the oven, through the "guide" and into the quench car. The quench car takes the red-hot coke to the quenching station, where it's sprayed with water, then dumped. (The link in post #15 will give you an idea of how the battery is set-up.)
The coke, ore or pellets, and limestone are usually kept in bins in a stockhouse alongside the blast furnace. This is usually a long structure (couple hundred feet) with a ramp at one or both ends, with one or two railroad tracks on top. Beneath are storage bins for the raw materials. The usual method is to load the ore, coke, etc. into hoppers at the storage fields, then push the loaded cars into position on top of the stockhouse for dumping into the storage bins.. Underneath the bins, and, in most cases, enclosed, is a scale car, also running on rails, which moves along under the bins. The raw materials are dropped into the scale car, which takes the material to the skip pit, usually located at the mid-point of the stockhouse. Here the material is dumped into the cable-operated skip car, which carries it up the skip bridge (a long, steeply inclined track) to the top of the furnace, where it is dumped onto the small bell, an arrangement for distributing the charge in the furnace. In addition, the scale car weighs each load so that the proper mix of raw materials is used.
I hope that this answers some of your outstanding questions. I see that Illus has taken care of the hot metal end of the process:thumb: , so I'll go bandage my fingers.
And, seriously, if you have more questions, just ask, as I
am pleased to be able to help.
