加热炉包括有连续加热炉和室式加热炉等。金属热处理用的加热炉另称为热处理炉。初轧前加热钢锭或使钢锭内部温度均匀的炉子称为均热炉。广义而言，加热炉也包括均热炉和热处理炉。
Heating furnaces include continuous heating furnaces and chamber type heating furnaces. The heating furnace used for metal heat treatment is also known as a heat treatment furnace. A furnace that heats the steel ingot or homogenizes the internal temperature of the ingot before blooming is called a soaking furnace. Generally speaking, heating furnaces also include soaking furnaces and heat treatment furnaces.
在锻造和轧制生产中，钢坯一般在完全燃烧火焰的氧化气氛中加热。采用不完全燃烧的还原性火焰（即“自身保护气氛”）来直接加热金属，可以达到无氧化或少氧化的目的。这种加热方式称为明火式或敞焰式无氧化加热，成功地应用于转底式加热炉和室式加热炉。
In forging and rolling production, steel billets are generally heated in an oxidizing atmosphere of complete combustion flames. The use of partially combustible reducing flames (i.e., self protective atmospheres) to directly heat metals can achieve the goal of no or little oxidation. This heating method is called open flame or open flame non oxidation heating and has been successfully applied to rotary bottom heating furnaces and chamber heating furnaces.
