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.

　　黑铁和白铁的加工就是在此基础上，加大力度的。同时，在生产中也要注意。各企业都建立了完善的评价体系，努力在提高产能的前提下降低能耗，生产的中间环节也努力减少污染物的排放。

　　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.

　　现在，很多人重视空气循环，尤其是在室内空气不太好的地方。如果空气不能被替代，那么我们的身体就会有问题。一般空气循环的佳设备是风管，它是一种具有很高使用价值的绿色材料。它大大减少了安装管与管之间的连接,使里面的配件漏气减少到低限度,因此,即使用于三到五年内,其压制模具的表面保持不变,使表面材料没有损坏,大大延长使用寿命的黑白铁加工螺旋风管、统一的平缝同时,继电器强和良好的密封。

　　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.

　　管密封必须更好,毕竟,如果不好会导致漏气,如果不要小看空气泄漏在一些重要的地方空气泄漏会导致事故,和很多人认为的帮助有很多,特别是在家庭生活为了防止一氧化碳中毒这些需要在厨房,卫生间通风处将安装空气管,这是我们必须生活的保证。

　　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.

　　随着黑、白铁加工技术的不断进步和创新，黑、白铁螺旋风管将在制冷空调行业发挥更大的辅助作用，在空调通风系统的空气循环中发挥更重要的作用。对于环境保护和的重要性，济南不锈钢烟幕在黑白铸铁加工技术和工艺上将不断取得进步，为保护我们的生活环境做出贡献。

　　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.
