A few days ago, the Ministry of Ecology and Environment released 39 key industries’ performance ratings and emission reduction measures. Among them, the long-process joint steel industry and the short-process steel industry performance grading indicators and emission reduction measures are as follows:

01Long Process United Steel

It is suitable for long-process steel joint enterprises (including electric furnaces that add molten iron), independent sintering, pelletizing, and steel rolling enterprises. Among them, the long-process steel company refers to the steel produced by the joint and closely related production processes such as raw material field, sintering, pelletizing, coking, ironmaking, steelmaking (electric furnace), steel rolling, lime, and self-provided power plants. enterprise.

Performance grading indicators:

1. A-level enterprise:

Encourage the implementation of emission reduction measures based on actual conditions.

2. Class B enterprise:

Among them, the production limit of sintering machine and pellet equipment is more than 10% (inclusive), and the production limit of lime kiln is 30% (inclusive) The above calculations are based on the minimum daily average value of the "Environmental Assessment Approved Capacity, Pollutant Discharge Permits, and the actual output of normal production in the previous year" as the basis; stop using National IV and below heavy-duty trucks (including gas) for transportation.

Red warning period: each converter (electric furnace) produces no more than 32 furnaces, which will reduce the production of iron pre-processes, blast furnaces and rolling processes, and reduce the overall production load. Among them, the production of sintering machines and pellet equipment is limited to more than 20% (inclusive) , The lime kiln’s production limit is more than 30% (inclusive), and the calculation is based on the minimum of the daily average values of the "Environmental Assessment Approved Capacity, Pollutant Discharge Permits, and the actual output of normal production in the previous year"; Cargo vehicles (including gas) for transportation.

3. B-level enterprise:

Yellow warning period: the coke oven load is reduced to less than 80% of the designed production load, based on the delayed coke discharge time; the use of heavy-duty trucks (including gas) of National IV and below for transportation is stopped.

Orange warning period: The number of steels per converter (electric furnace) is not more than 30, which will drive the overall reduction of production load. Among them, the sintering machine, pellet equipment, and lime kiln will stop production by more than 30% (inclusive) (single production line reduces production The load is calculated on the basis of the minimum daily average value of the three “capacity approved by the environmental assessment, the capacity specified in the pollution discharge permit, and the actual output of the previous year’s normal production”; if there are multiple production lines, the production line is stopped); the coke oven load is reduced to the design Within 80% of the production load, as the delayed coke delivery time; stop using the National IV and below heavy-duty trucks (including gas) for transportation.

During the red warning period: the number of steels per converter (electric furnace) is not more than 26 furnaces, which drives the overall reduction in production load. Among them, the sintering machine, pellet equipment, and lime kiln stop production by more than 30% (inclusive) (single production line reduces production The load is calculated on the basis of the minimum daily average value of the three “capacity approved by the environmental assessment, the capacity specified in the pollution discharge permit, and the actual output of the previous year’s normal production”; if there are multiple production lines, the production line is stopped); the coke oven load is reduced to the design Within 80% of the production load, as the delayed coke delivery time; stop using the National IV and below heavy-duty trucks (including gas) for transportation.

4. C-level enterprise:

Yellow warning period: the number of steels in each converter (electric furnace) is not more than 30, which will drive the overall reduction in production load. Among them, the sintering machine, pellet equipment, and lime kiln will stop production by more than 25% (inclusive) (single production line reduces production The load is calculated on the basis of the minimum daily average value of the three “capacity approved by the environmental assessment, the capacity specified in the pollution discharge permit, and the actual output of the previous year’s normal production”; if there are multiple production lines, the production line is stopped); the coke oven load is reduced to the design Within 65% of the production load, based on the delayed coke delivery time; stop using the National IV and below heavy-duty trucks (including gas) for transportation.

Orange warning period: the number of steels per converter (electric furnace) is no more than 26 furnaces, which drives the overall reduction in production load. Among them, the sintering machine, pellet equipment, and lime kiln stop production by more than 50% (inclusive) (single production line reduces production The load is calculated on the basis of the minimum daily average value of the three “capacity approved by the environmental assessment, the capacity specified in the pollution discharge permit, and the actual output of the previous year’s normal production”; if there are multiple production lines, the production line is stopped); the coke oven load is reduced to the design Within 65% of the production load, based on the delayed coke delivery time; stop using the National IV and below heavy-duty trucks (including gas) for transportation.

During the red warning period: each converter (electric furnace) has no more than 22 furnaces, which will drive the overall reduction of production load. Among them, the sintering machine, pellet equipment, and lime kiln will stop production by more than 50% (inclusive) (single production line reduces production The load is calculated on the basis of the minimum daily average value of the three “capacity approved by the environmental assessment, the capacity specified in the pollution discharge permit, and the actual output of the previous year’s normal production”; if there are multiple production lines, the production line is stopped); the coke oven load is reduced to the design Within 65% of the production load, based on the delayed coke delivery time; stop using the National IV and below heavy-duty trucks (including gas) for transportation.

5. D-level enterprises:

Yellow warning period: the number of steels per converter (electric furnace) is no more than 26 furnaces, which will drive the overall reduction of production load. Among them, the sintering machine and pelletizing equipment will stop production by more than 30% (inclusive) (a single production line reduces the production load, The minimum daily average value of the “EIA approved capacity, the capacity specified in the emission permit, and the actual output of the previous year’s normal production” shall be calculated based on the minimum daily average value; if there are multiple production lines, the production line shall be counted as the production line is stopped); the lime kiln is shut down; the coke oven load decreases Within 50% of the designed production load, it is calculated as the delayed coking time; stop using the National IV and below heavy-duty trucks (including gas) for transportation.

Orange warning period: the number of steels per converter (electric furnace) is not more than 22, which drives the overall reduction of production load; sintering machine, pellet equipment, and lime kiln stop production; coke oven load is reduced to less than 50% of the designed production load, Delay the coke time meter; stop using heavy-duty trucks (including gas) for transportation of China IV and below.

During the red warning period: sintering machine, pellet equipment, lime kiln, converter stop production; blast furnace stewing furnace; coke oven load is reduced to less than 50% of the designed production load, based on the delayed coking time; road transportation is stopped.
