The Ministry Of Industry And Commerce Has Made Rigid Rules For Steel Production And Other Indicators.

In July 12th, the Ministry of industry and information technology formally issued the "standard conditions for production and operation of the steel industry", which was led by the Ministry of industry and information technology. Iron and steel enterprises The production scale, energy conservation and emission reduction indicators have been clearly defined.

Among them, on the scale of production, the requirement for enterprises is that in 2009, the crude steel output of ordinary steel enterprises must be above 1 million tons, and the output of special steel enterprises must be above 300 thousand tons, and the ratio of alloy steel to more than 60%.

In process equipment, the effective volume of the blast furnace must be over 400 cubic meters, the nominal capacity of the converter should be over 30 tons, the nominal capacity of the electric furnace must be over 30 tons, the sintering machine area should be more than 90 square meters, and the coke oven chamber must be more than 4.3 meters high. The blast furnace must be equipped with pulverized coal injection and residual pressure generating units, and coke oven, blast furnace and converter must be equipped with gas recovery devices.

The coke oven must be controlled by coal moisture and equipped with CDQ device. The sintering machine must support the flue gas waste heat recovery. Desulfurization unit Steel rolling adopts regenerative heating furnace.

In energy consumption and Resource synthesis In terms of utilization, iron and steel enterprises must meet the requirements of energy consumption indicators for main production processes, which are in line with the "limit of energy consumption per unit of crude steel production process" and "the limit of energy consumption per unit of coke", of which the energy consumption of coking process is less than 155 kilograms of standard coal / ton, and the sintering process can consume less than 56 kilograms of standard coal / ton. The consumption of new water for tonnes of steel is not more than 5 tons, the comprehensive utilization rate of blast furnace slag is not less than 97%, converter slag is not less than 60%, and the slag of electric furnace is not less than 50%.

In terms of environmental protection, the discharge amount of tonne steel sewage in iron and steel enterprises should not exceed 2 cubic meters, the emission of tons of steel and smoke and dust should not exceed 1 kg, and the sulfur dioxide emission from ton steel should not exceed 1.8 kg.

In response, a senior member of a domestic iron and steel enterprise pointed out that the limitation of the scale of production will mainly involve the interests of some small businesses all over the country. Therefore, the attitude of local governments depends on whether the access conditions can be implemented.
