JB/T 50163-1999 This standard is a revision of ZB J01 013-88 "Energy Consumption Classification of Heat Treatment Pit Resistance Furnaces". This standard specifies the energy consumption levels of heat treatment pit resistance furnaces in machinery industry enterprises. Heat treatment pit resistance furnaces are divided into first, second and third grades according to comparable unit consumption. Those whose comparable unit consumption does not reach the third grade index are classified as out-of-grade. This standard was first issued on March 5, 1988.

. The standard stipulates the energy consumption level of heat treatment pit-type resistance furnaces (hereinafter referred to as lifting furnaces) in mechanical industrial enterprises 2 Energy consumption classification
Parallel furnaces are divided into first, second and first grades according to comparable unit consumption. Except for those whose comparable unit consumption index does not reach the third grade, they belong to the tenth grade. The comparable unit consumption classification of pit-type furnaces is shown in Table 1.

4 Calculation of heat-treatable equivalent weight
JE/T50163-1999
4.1: The equivalent weight of the medium-temperature pit furnace is calculated according to formula (2): G,-zGk,k.
Where: G.——Actual weight of a qualified heat-treated part, t: K,
——Process coefficient of this heat-treated part, see Table 2:——Filling coefficient of this heat-treated part.
Correction Due to the shape of the treated part, The coefficient that causes the change of furnace loading is called the loading coefficient of this type of heat-treated parts. (2)
When the loading volume of the heat-treated parts is 75% of the working area of ​​the furnace, and the weight of the heat-treated parts loaded in the furnace is less than 3% of the specified loading capacity of the equipment, the loading coefficient of this type of heat-treated parts is 1.5. In other cases, K is 1/2
Heat treatment 1.2
4.2 The equivalent weight of the parallel tempering furnace is calculated according to formula [3): Where: G is the actual weight of a certain qualified tempered part. : K.
- The tempering humidity coefficient of this type of parts, see Table 3; K is the process coefficient of this type of parts, see Table 3:
The loading coefficient of this type.
