　　The refrigeration and air-conditioning industry will change its production mode and adjust its product structure with the change of national policy. From the adjustment of product structure, it can be seen that energy-saving products have become the key research and development content and main products of enterprises. In order to achieve the goal of energy saving and environmental protection, all enterprises carry out relevant activities around the theme of energy saving and environmental protection, and increase investment in new product development, product design, manufacturing technology, technical transformation of production lines to promote equipment upgrading.

　　黑鐵和白鐵的加工就是在此基礎上，加大力度的。同時，在生產中也要注意節能。各企業都建立了完善的評價體系，努力在提高產能的前提下降低能耗，生產的中間環節也努力減少污染物的排放。

　　It is on this basis that the processing of black iron and white iron is intensified. At the same time, attention should be paid to energy saving in production. Every enterprise has established a perfect evaluation system, striving to reduce energy consumption on the premise of improving productivity, and the intermediate link of production also strives to reduce pollutant emissions.

　　現在，很多人重視空氣循環，尤其是在室內空氣不太好的地方。如果空氣不能被替代，那么我們的身體就會有問題。一般空氣循環的佳設備是風管，它是一種具有很高使用價值的綠色環保材料。它大大減少了安裝管與管之間的連接,使里面的配件漏氣減少到低限度,因此,即使用于三到五年內,其壓制模具的表面保持不變,使表面材料沒有損壞,大大延長使用壽命的黑白鐵加工螺旋風管、統一的平縫同時,繼電器強和良好的密封。

　　Nowadays, many people attach importance to air circulation, especially in places where indoor air is not very good. If air cannot be replaced, then our bodies will have problems. The best equipment of general air circulation is air duct, which is a kind of green environmental protection material with high use value. It greatly reduces the connection between the installation pipe and the pipe, and minimizes the leakage of the fittings inside. Therefore, even if it is used for three to five years, the surface of the pressing die remains unchanged, so that the surface material is not damaged, and the service life of the black and white iron is greatly prolonged when processing spiral air ducts and uniform flat seams. At the same time, the relay is strong and good. Seal up.

　　管密封必須更好,畢竟,如果不好會導致漏氣,如果不要小看空氣泄漏在一些重要的地方空氣泄漏會導致事故,和很多人認為的幫助有很多,特別是在家庭生活為了防止一氧化碳中毒這些需要在廚房,衛生間通風處將安裝空氣管,這是我們必須生活的保證。

　　Pipe sealing must be better. After all, if it is not good, it will lead to air leakage. If you do not underestimate that air leakage will lead to accidents in some important places, and many people think that there is a lot of help, especially in family life, in order to prevent carbon monoxide poisoning, these need to install air pipes in the kitchen, toilet ventilation, this is me. We must live with assurance.

　　隨著黑、白鐵加工技術的不斷進步和創新，黑、白鐵螺旋風管將在制冷空調行業發揮更大的輔助作用，在空調通風系統的空氣循環中發揮更重要的作用。對于環境保護和節能的重要性，濟南不銹鋼煙幕在黑白鑄鐵加工技術和工藝上將不斷取得進步，為保護我們的生活環境做出貢獻。

　　With the continuous progress and innovation of black and white iron processing technology, black and white iron spiral air ducts will play a greater auxiliary role in the refrigeration and air conditioning industry, and play a more important role in the air circulation of air conditioning and ventilation systems. For the importance of environmental protection and energy saving, Jinan stainless steel smoke will make continuous progress in black and white cast iron processing technology and technology, and contribute to the protection of our living environment.
