Some other method for single facer heating
Most single facer are heated by steam, but it need a boiler to supply steam to the single facer. The fuel of boiler may create some pollution to the environment, so in some countries, there are strict request on the air pollution, it is very difficult to get license to work on a bolier. Also in some countries, the fuel for the boiler is much expensive, but electric is cheaper, so they prefer heating by electric, for these difference customers’ request, we also can offer some other method of single facer heating.
The traditional heating method is steam heating, its advantage is the flute roller can be heated average, though the single facer runs in high speed, it still can make sure the quality of the corrugated cardboard, so all high speed machine are all in steam heating, and only can choose heating.
Another heating method for single facer is gas heating. The gas goes in to the flute roller, and burn inside of the roller, then to achieve heating. Also we can offer electric heating for single facer, we make quartz tubes inside of flute roller, then electric heat the quartz tubes to heat the flute roller.
The two heating method above, they all have a problem is that, the single facer can only run in low speed. Some factories says its maximum speed can be 60m/minute, but it is not the fact, it can only run in about 45m.minute. If run a little faster, the corrugated cardboard will be bad quality because of the uneven heating.
Oil heating is also a normal heating method for single facer, we heat the oil firstly, then the oil goes into single facer to heating the flute roller. It has a better heating effect than the gas heating, and the single facer can run in speed 80m/minute, but it also need a small boiler or other equipment to heating the oil.
For solving the problems above, we have a new model of single facer, it is special for the customers who can not adopt a boiler to offer steam. The model of single facer is SF10A, it adopts electric and oil exchange heating. On the single facer, there are two big roller for store oil, and in side of the roller, we equipped with stainless pipes, it does not like the quartz tubes easy to broken and need to change always, the stainless pipes has a long work life. Then we heating the oil by electric firstly, then the oil will go to the flute roller to heat the flute roller. So the heating is exchanged from the electric to the oil. This single facer can run in speed 80m/minute, and also can make sure good quality of corrugated cardboard.
This model of single facer is only for single face corrugated cardboard, can not be used in the multiply corrugated cardboard production line, because if 3/5/7 layer corrugated cardboard, they have many machine need to be heated, not only single facer, like double facer, pre heater, etc. So if you want to by multiply corrugated cardboard production line, we can only offer steam heating machine. If you want to produce 2 ply corrugated cardboard, the SF10A single facer is also an option for you.
