JB/T 50170-1999 This standard is a revision of ZB J01 020-88 "Energy Consumption Classification of White Corundum Smelting Electric Furnaces". This standard specifies the energy consumption level of white corundum abrasive smelting electric furnaces with a capacity of 360~2500kVA. Other capacities of white corundum abrasive smelting electric furnaces can be implemented as a reference. White corundum smelting electric furnaces can be divided into first, second and third grades according to their furnace base unit consumption. Furnace bases that do not meet the third grade index are classified as off-grade. This standard was first issued on March 5, 1988.

The provisions contained in the listed standards shall constitute the provisions of this standard by citing them in this standard. When this standard was published, the versions shown were all valid. All standards will be revised, and the parties using this standard should explore the feasibility of using the latest version of the following standards. GB 2479-t996 General Corundum White Jade
3 Energy Consumption Classification
White corundum smelting electric furnaces are divided into first, second and third grades according to their furnace base unit consumption: except for the third grade whose furnace output unit consumption does not reach the third grade index: the furnace base unit consumption classification of corundum smelting electric furnaces is shown in the table! Table
Furnace Unit Gross Index
kw·h/t—Product Block
>2020-2070
First-grade corundum blocks are made into process balls that meet GB24. 2 All smelting electric furnaces should have complete operation supervision, environment design and material composition analysis records. 3 The scope of energy consumption statistics is limited to the power consumption directly used for smelting. 4 Furnace unit consumption calculation
>2070-2200
The furnace unit consumption of the self-corundum smelting electric furnace is the average furnace unit consumption per ton of white corundum block during the statistical period, calculated according to formula (1): W
In the formula, the average furnace unit consumption of the white corundum smelting electric furnace during the statistical period, kw+hll; the total power consumption of the furnace during the statistical period, W·H; EG
The output of the first-grade self-corundum block of the furnace during the statistical period is 1. The output of the first-grade dead corundum is measured in full. 2 The smelting power consumption is based on the maximum value measured by the active power meter using a transformer. Approved by the State Machinery Industry Bureau on December 30, 1909, and implemented on June 1, 2000
