按炉温分布，炉膛沿长度方向分为预热段、加热段和均热段。进料端炉温较低为预热段，其作用在于利用炉气热量，以提高炉子的热效率。加热段为主要供热段，炉气温度较高，以利于实现快速加热。

According to the distribution of furnace temperature, the furnace is divided into preheating section, heating section and uniform heating section along the length direction.

The lower temperature of the feed end is the preheating section, and its function is to increase the heat efficiency of the furnace by utilizing the heat of the furnace gas.

The heating section is the main heating section, and the furnace gas temperature is relatively high, which is conducive to rapid heating.

加热炉能快速加热，氧化和脱碳少，适用于加热圆形料坯和钢管。与行星轧机相配合，可用来加热连铸板坯；也可对某些钢材进行局部加热。缺点是单位炉长的生产能力低，炉子热效率较低。

The heating furnace can be heated , with less oxidation and decarburization, and is suitable for heating round billets and steel pipes. It can be used for heating continuous casting slab and heating some steel products. The drawback is that the production capacity of unit furnace length is low and furnace thermal efficiency is low.

蓄热式加热炉的传导传热：传导传热是温度不同的物体直接接触（或物体存在温差）由于自由电子的运动（对于钢材）或分子的运动（对于炉气）而发生的热交换现象，此种传热发生在钢材表面及内部和钢材及炉底之间。

Conduction of conduction in a regenerative heating furnace: conduction heat transfer is the direct contact of a different temperature (or the existence of a temperature difference between a body) due to the movement of free electr (for steel) or the movement of molecules (for furnace gas), which occurs between the surface and inside of the steel and between the steel and the bottom of the furnace.

加热炉基础知识介绍：

燃气式加热炉有哪些安全技术规程？Itisnotallowedtoremovefirefromtheburner。笔者知道到燃气式加热炉的安全技术规程如下。燃气式加热炉焚烧前，应关好人孔，烟道挡板开至1/3一1/2,树立燃料油体系循环和质料循环，准备好浸透柴油的焚烧棒。正常操作中应常常查看炉子燃烧状况，随时调理，发现异常，当即向领导报告，采纳措施进行处置。

What are the safety technical regulati for gas fired reheating furnaces?蓄热式加热炉的传导传热：传导传热是温度不同的物体直接接触（或物体存在温差）由于自由电子的运动（对于钢材）或分子的运动（对于炉气）而发生的热交换现象，此种传热发生在钢材表面及内部和钢材及炉底之间。 I understand that the safety technical regulati for gas fired reheating furnace are as follows. Before burning gas-fired heating furnace, manhole should be closed, flue baffle should be opened to 1/3-1/2, fuel oil system cycle and material cycle should be set up, ready to immerse diesel fuel burning rod. Normal operation should often check the furnace combustion status, at any time to adjust, found abnormal, immediately report to the leadership, adopt measures for.
