由若干个摆在一条线上的加热室所组成。加热室和加热室之间设间室，传送料坯的辊子设在间室内，坯单根（或双根）地通过各加热室和间室而被加热。每个加热室与相邻的间室构成一个“炉节”，所以又称节式炉。
It c***ists of several heating chambers on one line. There is a room between the heating chamber and the heating chamber. The rollers of the conveying blanks are arranged in the indoor room, and the single root (or two roots) of the billet is heated through the heating chambers and chambers. Each heating chamber and the rooms form a "furnace section", so it is also called a section furnace.
对流传热：对流传热是炉气与钢材表面接触时的热交换过程，包括炉气各部分发生位移所产生的对流作用及炉气分子之间的导热作用。
Convective heat transfer: convection heat transfer is the heat exchange process of the contact between the furnace gas and the steel surface, including the convection of the displacement of each part of the furnace gas and the heat conduction between the molecules of the furnace gas.
