加熱質(zhì)量好。加熱時(shí)介質(zhì)出爐溫度需符合工藝要求，防止局部過(guò)熱出現(xiàn)結(jié)焦、結(jié)炭或危險(xiǎn)。
燃料消耗低。站場(chǎng)用加熱爐的能量消耗有10～15％消耗于爐子上，節(jié)省的燃料對(duì)降低單位成本和節(jié)約能源都有重要意義。
The quality of heating is good. The heating temperature of the medium should meet the requirements of the process, preventing the local overheating from coking, carbon or explosion.
Fuel cumption is low. The energy cumption of the reheating furnace in the station is 10 ~ 15% on the furnace. The fuel saving is of great significance to reducing unit cost and saving energy.
按爐溫分布，爐膛沿長(zhǎng)度方向分為預(yù)熱段、加熱段和均熱段。進(jìn)料端爐溫較低為預(yù)熱段，其作用在于利用爐氣熱量，以提高爐子的熱效率。加熱段為主要供熱段，爐氣溫度較高，以利于實(shí)現(xiàn)快速加熱。
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.
加熱爐能快速加熱，氧化和脫碳少，適用于加熱圓形料坯和鋼管。與行星軋機(jī)相配合，可用來(lái)加熱連鑄板坯；也可對(duì)某些鋼材進(jìn)行局部加熱。缺點(diǎn)是單位爐長(zhǎng)的生產(chǎn)能力低，爐子熱效率較低。
The heating furnace can be heated quickly, 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.
蓄熱式加熱爐的傳導(dǎo)傳熱：傳導(dǎo)傳熱是溫度不同的物體直接接觸（或物體存在溫差）由于自由電子的運(yùn)動(dòng)（對(duì)于鋼材）或分子的運(yùn)動(dòng)（對(duì)于爐氣）而發(fā)生的熱交換現(xiàn)象，此種傳熱發(fā)生在鋼材表面及內(nèi)部和鋼材及爐底之間。
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.
