用于加热小断面料坯的炉子只有预热段和加热段。

习惯上还按炉内安装烧嘴的供热带划分炉段，依供热带的数目把炉子称为一段式、二段式，以至五段式、六段式等。50～60年代，由于轧机能力加大，而推钢式炉的长度受到推钢长度的限制不能太长。

The furnace used for heating ***all broken fabric billet is only preheating section and heating section.

It is customary to divide the furnace section according to the heating belt with the burner in the furnace. According to the number of tropics, the furnace is called the one section, the two section, and the five section and the six section. In the 50~60 era, due to the increase of rolling mill capacity, the length of pusher furnace must not be too long due to the length of steel pushing.

加热炉基础知识介绍：

燃气式加热炉有哪些安全技术规程？燃料气，空气的相对速度二者之间的相对速度也对混合有极大的影响，速度差越大，混合就越快。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***报告，采纳措施进行处置。

The basic knowledge of reheating furnace is :

What are the safety technical regulati*** for gas fired reheating furnaces?观察气体燃料从扩散燃烧逐步地改变成半预混燃烧的变化过程可以更加清楚地了解半预混燃烧燃烧，预混燃烧的特点。 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.

焚烧时司炉工不能面对火嘴及看火窗，避免回火伤人。如火焰平息，应当即封闭燃料阀，炉膛内需用蒸汽吹扫后，方能重新焚烧。进入炉内维修时，应处置进入设备内作业手续。防爆门不得用其它物件堵死，避免失掉防爆效果。引***时要注意脱净存水及凝缩油，并在安全地址排空15分钟以上，经化验剖析含氧量小于1%,方可投用焚烧。Inordertoeffectivelyutilizeexhaustheat,apreheatairandgasheatexchangerisinstalledintheflue,oraHRSGisinstalled。***进炉前一定要通过阻火器。

When burning, the stoker can not face the fire mouth and look at the fire windows, so as to ***oid backfire and injure people. If the flame is subsided, the fuel valve should be closed immediately, and the furnace needs to be cleaned by steam before it can be re burned. When entering the furnace maintenance, the operation procedures for entering the equipment should be of. The explosion-proof door should not be blocked by other objects, so as to ***oid the explosion proof effect. Attention should be paid to the removal of water and condensate when gas diversion, and more than 15 minutes at a safe address, after analysis of laboratory oxygen content less than 1%, can be put into incineration. Gas must be passed through the flame arrester before entering the furnace.
