新疆第一建筑工程公司采用的“工频涡流加热养护混凝土”的方法是我国首次应用养护混凝土的新工艺。它是在使用钢模板后根据电磁感应原理及金属导热原理而提出来的一种新型电热转换养护混凝土的方法。其特点是加热方式简单,维护安全方便,不需过多的辅助设备。加热均匀,控制方便,容易实现自动控制。降低了劳动强度,提高了生产率。缩短了施工周期,尤以高层建筑更为显著。根据电磁感应原理,一根有交变电流通过的导线,穿过铁管在管壁内产生交变的磁场,由于铁管有一定的厚度就感应产生电动势和电流。在工业交流电感应下,管壁内产生旋涡式流动的电流称为工频涡流。由于铁管中电阻的存在,涡流在管壁内产
The “Industrial frequency vortex heat curing concrete” method adopted by Xinjiang First Construction Engineering Company is the first application of a new process for curing concrete in China. It is a new type of electric heat conversion curing concrete method based on the principle of electromagnetic induction and the principle of metal heat conduction after using the steel template. Its characteristics are simple heating methods, safe and convenient maintenance, without excessive auxiliary equipment. Even heating, easy control, easy to achieve automatic control. Reduce labor intensity and increase productivity. The construction period is shortened, especially in high-rise buildings. According to the principle of electromagnetic induction, a wire with alternating current passing through the iron tube generates an alternating magnetic field in the wall of the tube. Since the iron tube has a certain thickness, it induces electromotive force and current. Under the induction of industrial alternating current, the eddy current generated in the pipe wall is called the power frequency eddy current. Due to the presence of resistance in the iron pipe, eddy currents are produced in the pipe wall.
