随着中国国民经济的发展,对高品质钢管的需求量正在迅速增加,越来越多的科技人员对这一课题进行研究。对于热轧无缝钢管生产流程中的加热过程,目前在中国主要还是利用环形加热炉,环形炉由于自身的炉体特点成为管坯加热过程的主要载体,不过步进式加热炉在某些钢厂也用,只是该设备造价高,当采取上下两面加热时,由于炉底水冷管较多,冷却水的消耗量以及冷却水消耗的热能都较高。环形加热炉炉身固定,炉底转动,像一个旋转托盘可使数百根管坯缓缓旋转,其主要加热区处在进出口的中段,可用燃气或液体燃料。管坯随炉底的转动而完成由进料口到出料口的运行。环形
With the development of China’s national economy, the demand for high-quality steel pipes is rapidly increasing, and more and more scientific and technological personnel are studying the subject. For the hot-rolled seamless steel pipe production process in the heating process, mainly in China or the use of ring furnace, the ring furnace due to its own furnace body characteristics become the main carrier tube heating process, but the step furnace in some steel The factory is also used, but the high cost of the equipment, when taken up and down both sides of the heating, due to the bottom of the water pipe more, the consumption of cooling water and cooling water consumption are high heat. Furnace ring furnace fixed, bottom rotation, like a rotating tray can make hundreds of slowly rotating tube, the main heating zone in the middle of the import and export, available gas or liquid fuel. Tube with the rotation of the furnace to complete the operation of the feed port to the discharge port. Ring
