燃料氣與空氣的流動(dòng)方式 主要可以歸納為四種,燃料氣噴射到靜止的空氣中;燃料氣和空氣平行流動(dòng);燃料氣和空氣流動(dòng)時(shí)相互之間有一定的夾角;燃料氣和空氣呈旋流運(yùn)動(dòng)。
The flow of fuel gas and air can be divided into four main types, the fuel gas injected into the air; the fuel gas and the air flow in parallel; the fuel gas and the air flow between a certain angle; the fuel gas and air in a cyclone movement.
用于加熱小斷面料坯的爐子只有預(yù)熱段和加熱段。
習(xí)慣上還按爐內(nèi)安裝燒嘴的供熱帶劃分爐段,依供熱帶的數(shù)目把爐子稱為一段式、二段式,以至五段式、六段式等。50~60年代,由于軋機(jī)能力加大,而推鋼式爐的長度受到推鋼長度的限制不能太長。
The furnace used for heating small 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.
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.
