Overlay Base Products in Roof Panel Roll Forming Machine Manual

Release date:2014-07-21  stem:http://www.broswright.com/

Roll forming machinery products are in general melted by the heat from the upper roll when the melting point of the upper roll forming products is higher than lower products according to roof panel roll forming machine manual. The melting point of the base roll forming machinery products must be lower than that of the overlay roll forming products. This restrict is not suitable for the fabrication of the three layers clad roll forming machinery products since one of the surfaces is free solidified and is not sound.

For this reason, roll forming machinery is not enough for the roll caster to cast three layers and the alloy whose melting point is higher than overlay can be chosen as the base roll forming products according to roof panel roll forming machine manual. The surface temperature and surface condition of roll forming machinery are not the same at roll contact surface as well as the solidified surface so the control of the semisolid condition is not easy. The semisolid roll forming machinery condition affects the bonding of the roll forming products since the solid fraction of the free solidified surface must be set low when three layers is cast. In this way, roll forming machinery are not sufficient for producing final products as the roll caster is needed for clad roll forming products. That is why two kinds of roll forming machinery and roll casters can be developed to cast three layers in terms of unequal diameter and vertical tandem according to roof panel roll forming machine manual.

These roll forming machinery casters have properties and can be assembled from a large lower roll and two small upper rolls on the basis of overlay roll forming products. The second small upper roll cast roll forming machinery can be adapted to the first small upper roll so as to prevent the mixture of the melts. This enables roll forming machinery to separate the molten metal of the overlay from the base roll forming products around the pivot by tracing the solidified metal.

When the roll forming machinery scraper does not move, the melting temperature of the second roll forming products is higher than that of the first and third products since they are completely solidified according to roof panel roll forming machine manual. The roll forming machinery scraper prevents the leek from melting even when the temperature of roll forming machinery surfaces becomes lower than the solidus line so as to realize the bonding. The melt of roll forming machinery in the first and third roll forming products be heated up to the solidus in some ways according to roof panel roll forming machine manual.
