number of each furnace type.
steel industry further, the share consists of 42% blast furnace makers and 38% casting
or forging steelmakers — the two groups account for 80% of the share of the iron
and steel industry. For the breakdown of the percentage of the metallic machine
manufacturing industry, the share consists of 38% of the aluminum industry and
33% of the heat-treating processing industry. To promote the application in a wider
range of industries in the future, it will be necessary to conduct analyses in industries
other than blast furnace makers in the iron and steel industry, the casting or forging
steel industry, the aluminum industry, and the heat-treating processing industry.
A case analysis on the basis of the types of fuel is shown in
