The Norm of Energy Consumption per
Unit Product of Sponge Titanium
1 Application Scope
This Standard specifies the specifications, calculation principle and calculation method,
and energy-saving management and measures of the norm of energy consumption
per unit product of sponge titanium (hereinafter referred to as energy consumption).
This Standard applies to the calculation, evaluation and assessment of products’
energy consumption of the manufacturer who manufacture sponge titanium using the
magnesium thermal reduction process (the Kroll method).

3 Terms and Definitions
For the purposes of this Standard, the following terms and definitions and those
defined in GB/T 2589 apply.
3.1
primary energy sources
Coal, natural gas, crude oil and other energy sources.
3.2
secondary energy sources
Coke, fuel oil, petroleum coke, coal gas, electric power, petroleum products (gasoline,
diesel and kerosene), heating power and other energy species specified by the
national statistical system.
3.3
Energy consumption medium
The operation material which is consumed during the production process and is not
used as a raw material nor incorporated in products, and whose production or
preparation requires direct energy consumption.
3.4
unit energy consumption in working procedure
The energy consumed by per unit qualified product during the manufacturing process
of the manufacturer.
3.5
unit object consumption in working procedure
The quantity of material object of some energy source consumed by per unit qualified
product of the manufacturer in the manufacturing process.
3.6
unit energy consumption of technology
The ratio of the energy consumed by all manufacturing procedures for the production
of some product to the quantity of qualified products manufactured during the statistical
reporting period.
3.7
assistant energy consumption
The ratio of the energy consumed by the assistant manufacturing system to the
quantity of qualified products manufactured during the statistical reporting period.
3.8
enterprise integrated energy consumption
The total of unit energy consumption of technology, assistant energy consumption and
loss allocation.
