JB/T 50153-1999 This standard is a revision of ZB J01 003-87 "Energy Consumption Classification of Forging Heating Furnaces". This standard specifies the energy consumption levels of flame furnaces used for forging heating in mechanical industrial enterprises. Forging heating furnaces are divided into special, first, second and third grades according to the comparable unit energy consumption per ton of qualified forgings. Those with comparable unit energy consumption that does not meet the third grade index are classified as out-of-grade. This standard was first issued in 1987.

The relevant research institute of the standard proposed the drafting of this standard Unit: The Fifth Design Institute of the former National Machinery Commission, the Ministry of Machinery Industry Energy Conservation Center This standard is drafted by Feng Zhusi and Xiaoyun. This standard was first issued in 1987. The People's Republic of China Machinery Industry Standard Energy Consumption Classification of Forging Heating Furnaces (Internal Use) This standard specifies the energy consumption classification of forging furnaces used in industrial enterprises, and the energy consumption classification of JB/T 50153-1999

B: Single heating furnace or furnace Fuel consumption during the statistical period, kg or Nmx—fuel coefficient. See Table 2:
R——furnace type coefficient, see Table 3:
G, a single hot expansion or furnace T heat forging weight during the statistical period, "4 forgings equivalent weight
Considering the degree of hydrogen impurities, material wind problems and other factors, the forging quality of the part is converted to qualified, and the qualified weight of the part is calculated according to the formula (2): G=EG (R+K,)

Wu Zhong: - The weight of qualified parts of a single furnace in the statistical category is calculated based on the weight of the forgings of the same type, t. The corresponding number of forgings of a certain method is K, see Table 4, Table 5, Table 6, and the complexity of the forgings is different. See Figure A1 and Figure A2 in the standard appendix; K-type hub parts corresponding to the material weight coefficient, see Table. 4.2 Various coefficients
