Comparison of multi-log heating furnace and single log heating furnace

Many friends asked, “Judy, What is different between multi-log heating furnace and single log heating furnace?’

Actually both furnaces are widely used at aluminum profile extrusion production line; their characteristic is different, so their function is different.

Firstly, the advantage of single log heating furnace is short heating up time (around 2 hours). At many foreign countries, their law or National Labor Committee requires the factory to carry out 8 hours working per day system or work on two shifts (16 hours). In this case, single log heating furnace will play an important role to increase the efficiency.

Secondly, multi-log heating furnace heating up time is longer, why so many aluminum extrusion factories still using it? At China, aluminum extrusion equipment keeps running day and night, (24 hours per day), so they can save the equipment heating up time. Before aluminum profile extrusion, many aluminum extrusion equipment need to be heat up to certain temperature, like aluminum extrusion press container, aluminum billet heating furnace, aluminum extrusion die furnace and so on. If the aluminum billets in the multi-heating furnace, their crystal will become more uniformity in the high temperature condition. When aluminum extrusion factories cast the aluminum billet or buy aluminum billet from others, they won’t do the homogenizing process. If they use the multi-log heating furnace, the billet was heat for long time, interior structure will be uniformity. It is good for aluminum profile extrusion.

When you visit China aluminum extrusion factories, you will find that they heat up the aluminum billet, shear short and put aside of aluminum extrusion press for cooling down a little white, actually they are using the homogenizing theory.

A coin always has two sides, choose one which is suitable to you according to your own situation and take advantage of their characteristics. They can increase your working efficiency and create more profits.
