Foreword

YS/T 124 "carbon products manufacturing Determination and calculation of heat balance of the furnace" is divided into five parts. --- Part 1. rotary kiln; --- Part 2. Tank calciner; --- Part 3. Electrical calciner; --- Part 4. roaster; --- Part 5. Graphite resistance furnace. This section YS/T 124 Part 5. This section drafted in accordance with GB/T 1.1-2009 given rules. This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized. This part is YS/T 124-1994 "carbon products manufacturing Determination and calculation of heat balance of the furnace" in the graphite resistance furnace section of Amendments. Compared with YS/T 124-1994, the main changes are as follows. --- Specification standard unit of measurement, symbols and text formatting; --- Highlighting the standards of rigor, unity. The non-ferrous metal part by the National Standardization Technical Committee and centralized. This part of the Aluminum Corporation of China Guizhou Branch is responsible for drafting.
