加强技术标准的宣贯和发行工作。制定技术标准的目的在于运用。只有技术标准得到运用，才能发挥作用，取得效益。而技术标准的发行和宣贯工作，是技术标准运用工作的重要环节，做好技术标准的发行工作十分重要。
To strengthen the technical Xuanguan and distribution work. The pure of formulating technical is to use it. Only with the application of technical can the effect be played and the benefit is achieved. The technical issue and publicizing the work, is an important part of the use of technical , good technical issue is very important.
加热炉的分类:
1.有纯加热炉，如常压炉、减压炉等；有加热炉反应炉，如裂解炉、焦化炉等。
2.按传热方式分类：有纯对流式炉、辐射对流式炉和辐射式炉。
The classification of the heating furnace:
1. there are pure heating furnaces, such as ctant pressure furnace, pressure reducing furnace, and so on; there are reheating furnace reaction furnaces, such as cracking furnace and coking furnace.
2. classified according to the heat transfer mode: there are pure convection furnace, radiant convective furnace and radiant furnace.
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.
转底式加热炉
炉身固定，炉底转动，放置在炉底上的料坯随炉底转动由进料口移送到出料口。根据炉底的形状，转底式加热炉可分为环形炉和盘形炉两种，冶金厂轧钢车间多用环形炉。
Bottom reheating furnace
The furnace body is fixed and the bottom of the furnace is rotated, and the billet placed on the bottom of the furnace is transferred to the discharge port from the feed inlet with the rotation of the furnace bottom. According to the shape of the furnace bottom, the rotary hearth furnace can be divided into two types: the annular furnace and the disc type furnace.
