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.

台车式加热炉是加热炉系列中***常见的一种加热设备，台车式加热炉的结构简单，比较通用，而且操作容易，适合于钢铁、石油、化工等多个产业。

The trolley type heating furnace is one of the most common heating equipment in the series of heating furnace. The structure of the trolley type heating furnace is simple, common and easy to operate. It is suitable for many industries, such as steel, petroleum, chemical industry and so on.

台车式加热炉的结构一般是由辐射室、对流室及烟囱组成。辐射室也就是燃烧室，将燃料放进辐射室进行燃烧产生高温，以对传播热的方法持续将局部热量传给对流室炉管内活动着的油品。然后通过对流室和烟囱将油品和烟中的热量进行吸收，传递给产品。

The structure of the trolley type heating furnace is generally of a radiation chamber, a convection chamber and a chimney. The radiation chamber is also the combustion chamber, which puts the fuel into the radiation chamber for combustion to produce high temperature, and continuously transfers the local heat to the oil moving in the convection chamber furnace tube by means of heat tran***ission. Then the heat and oil in the oil and ***oke are absorbed and tran***itted to the product through the convection chamber and the chimney.
