Guide: in addition, the environmental protection problems of fastener enterprises have been paid more and more attention by major enterprises, and the harm of direct and indirect pollution and damage to the earth and workers caused by wastewater, waste residue and oil mist emissions has been widely recognized.

"In addition, the environmental protection problems of fastener enterprises have been paid more and more attention by major enterprises. The harm of direct and indirect pollution and damage to the earth and workers caused by the discharge of waste water, waste residue and oil mist has been widely recognized by people. A series of new scientific and technological products have brought vitality to modern fastener manufacturing. In order to change the current environmental protection situation of some enterprises, it needs funds, normalizing treatment rooms for unimportant shafts when necessary, and static electricity collection Oil mist collector, waste acid and sewage recovery device, and gas-phase antirust film replacing mechanical oil pollution are also being used by fastener enterprises. "

by the end of 2007, there were more than 7000 fastener enterprises in China (excluding Hong Kong, Macao and Taiwan). According to the statistics of the National Bureau of statistics, there were 1449 Enterprises above Designated Size in the fastener industry in 2006. In the past five years, fastener enterprises have concentrated in Ningbo, Wenzhou and Haiyan areas along the East China coast. The fastener industry has formed a pattern of three "carriages": foreign-funded enterprises with advanced equipment and standardized management; Private enterprises, with brand-new equipment plants and simple management levels; State owned enterprises, with strong technical strength, can be revitalized through technological transformation. These three carriages, while giving full play to their respective advantages and opening up the market, also promote the development of production technology in China's fastener industry

according to incomplete statistics, there are more than 2700 sets of heat treatment equipment in China's fastener industry, including more than 1650 sets of controllable atmosphere continuous heating belt furnaces. Some fastener enterprises rely on some professional heat treatment plants to implement outsourcing processing. The total annual output of fasteners in China has reached more than 5.2 million tons, and about 2.2 million tons of high-strength fasteners need heat treatment. According to the national average price, the heat treatment and tempering of fastener enterprises are mainly based on continuous belt furnace processing. At present, the average market price is about 725 yuan/ton, and the annual processing income is estimated to be about 1.55 billion yuan. According to the calculation that the average electricity cost of fastener heat treatment accounts for about 70% of the processing income, the annual electricity cost is 1.085 billion yuan, and the average electricity price is 0.7 yuan/kw h. Power consumption 15.5 × 109KW. H can calculate the average energy consumption of fastener processing 775kw H/t (equivalent to about twice the average heat treatment energy consumption of 425 kw.h/t in European and American countries and 323 kw.h/t in Japan)

from the above data, it can be seen that the task of energy conservation and emission reduction in fastener heat treatment in China is very arduous. The implementation of the new energy conservation law not only requires the fastener association to undertake the energy conservation management of the whole enterprise; Fastener enterprises are also required to become social models in their own energy conservation, so as to better play a leading role, so as to ensure that energy-saving systems and measures are grasped by people who have now occupied a dominant position in the market, and illegal energy use behaviors are investigated

in addition, the environmental protection problems of fastener enterprises have been paid more and more attention by major enterprises. The harm of direct and indirect pollution and damage to the earth and workers caused by the discharge of wastewater, waste residue and oil mist has been widely recognized. A series of new scientific and technological products have brought vitality to the manufacturing of modern fasteners. In order to change the current environmental protection situation of some enterprises, it takes money and time. Electrostatic oil mist collectors, waste acid and sewage recovery devices, gas-phase antirust films to replace mechanical oil pollution, etc. have also been selected by fastener enterprises

starting from the "plastic limit makes the cost low", reduce the use of packaging plastic film bags, further stimulate people's awareness of environmental protection, and consciously produce measures to protect the environment, such as "choose computer reading, reduce the amount of paper", "bring your own water cup and kettle", "use energy-saving lamps", "industrial production water recycling", etc., in order to finally change people's production and living habits and concepts, and establish environmental awareness. ISO14000 environmental protection system certification has also given birth to many garden factories in new industrial parks after relocation

therefore, in terms of energy conservation and environmental protection alone, fastener enterprises will have many options in the future, and it is entirely possible to form "different solutions for various solutions."
