After the melt leaves the cupola furnace, the next step in the production is the spinning of fibers. This is normally done by slowly pouring the molten charge onto a spinning machine, which consists of 3-4 wheels rotating at high speed. This splits the melt into droplets that form fibers that are subsequently gathered and pressed.
It's important that the melt hits the spinning machine at exactly the right spot to have a high spinning yield. If this doesn't happen, the percentage of waste created increases.
One problem is with the end of the tap channel that leads the melt from the cupola furnace to the spinning machine. Melt tends to solidify on the end and thereby changes the direction of the melt stream resulting in a lower spinning yield. By using Linde's patented application, "Tap stream burner", the end of the tap channel can be kept clean of solidified melt ensuring higher spinning yields. |
