Introduction of GB 29448-2022

The norm of energy consumption per unit production of sponge titanium and titanium ingot 1 Scope This document specifies the norm level, technical requirements, statistical range, and calculation method for the energy consumption per unit product (hereinafter referred to as "energy consumption") for sponge titanium, titanium and titanium alloy ingots (hereinafter referred to as "titanium ingots"). This document is applicable to the calculation and assessment of energy consumption , as well as energy consumption control for new, renovated, and extended projects of enterprises producing sponge titanium using magnesium reduction distillation method, and producing titanium ingots using vacuum consumable arc furnace. This document is not applicable to the calculation and assessment of energy consumption, as well as energy consumption control for new, renovated, and extended projects of enterprises producing sponge titanium using electrolysis and other methods, and producing titanium ingots using a cold bed furnace. 2 Normative references The following documents contain requirements which, through reference in this text, constitute provisions of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 2524 Titanium sponge GB/T 2589 General rules for calculation of the comprehensive energy consumption GB/T 12723 General principles for establishing allowance of energy consumption per unit throughput GB/T 26060 Titanium and titanium alloy ingots 3 Terms and definitions For the purposes of this document, the terms and definitions given in GB/T 2589 and GB/T 12723 apply.   4 Norm level of energy consumption 4.1 See Table 1 for the norm level of energy consumption per unit product of titanium sponge, of which Level 1 refers to the lowest energy consumption. Table 1 Norm level of energy consumption per unit product of titanium sponge Unit in kg of standard coal per ton ....... This document is developed in accordance with the rules given in GB/T 1.1-2020 Directives for standardization - Part 1: Rules for the structure and drafting of standardizing documents. This document replaces GB 29136-2012 The norm of energy consumption per unit product of sponge titanium and GB 29448-2012 The norm of energy consumption per unit production of titanium and titanium alloy ingots. In addition to structural adjustments and editorial changes, the following main technical changes have been made with respect GB 29136-2012 and GB 29448-2012: a) The physical unit consumption norm of sponge titanium production process and the energy consumption limit of production process are deleted (see 4.4 and 4.2 of GB 29136-2012); b) The comprehensive energy consumption norm per unit product of sponge titanium is modified (see Table 1 hereof; Tables 3, 4 and 5 of GB 29136-2012); c) The comprehensive energy consumption norm per unit product of titanium ingots is modified (see Table 2 hereof; Tables 1, 2 and 3 of GB 29448-2012). This document was proposed by and is under the jurisdiction of the Standardization Administration of the People’s Republic of China. The previous edition of this document and standards replaced by this document is as follows: ——It was first released in 2012 as GB 29448-2012; ——This is the first revision, and the contents of GB 29448-2012 The norm of energy consumption per unit production of titanium and titanium alloy ingots were incorporated in the revision.
