General data

Steel mills process iron ore and coal and produce steel. Steel mills can be built by a player. Building cost is £144,000,000. Steel mills have 4 possible layouts.

Both cargoes are a must. On the lowest production level the missing cargo would be taken from internal resources, but only when the other cargo is transported to the industry. Steel mill production is calculated from 6 furnaces. Initial values for furnaces is shown in the table (production data is calculated for 8 cycles a month. During game play, there are 8 or 9 cycles, while the total amount of distributed cargo is adjusted with property for minimal amount of cargo distributed). Amount of material used is calculated as coal=1.4*steel, ore=1.2*steel.

Every furnace can be upgraded to the best one for the current date. The smallest furnace is upgraded first.

Production change

Changing production level is calculated by comparing the amount of cargo waiting and amount of material, required for production. If there is not enough cargo waiting, production changes. Industry can rise production by 1 and decrease to any value.

Increasing production on high production levels also requires at least 50% of steel being transported.

When industry has a very low production level and did not produce enough cargo last month, it tests close down conditions. Industries in service have a close down chance reduced by 50%. Newly built industries can be closed only if they are at least 2 year old. Industries, built by the random map generator or map editor, can be closed only if they are at least 5 year old. A close down chance is 3%.

Conditions for number of furnace going up

(Current production*6/5*8 * 3 < Amount of ore stored) and (Current production*7/5*8 * 3 < Amount of coal stored)

Conditions for number of furnace going down

(Current production*6/5*8 > Amount of ore stored) or (Current production*7/5*8 > Amount of coal stored)

Where Current production specifies amount of steel produced every 256 ticks.

Stockpile size

Cargo acceptance is limited by storage capacity. If the stockpile is in overflow, the industry stops accepting cargo until the stockpile is down to 75% of capacity, at which point the industry will start accepting cargo again.

Possible locations

Steel mills should be built on flat land far from towns (Rz0 + 16 < Ed). They can't be built near other steel mills, factories, coal and ore mines.
