The strip surface has become sound as the meniscus in the roof ridge cape roll forming machine technology is free from the vibration. In this way, some devices can be induced to make strip surface sound. However, defects in the roof ridge cape roll forming machine technology might be observed in some cases on the strip cast by the high speed roll caster. For instance, the roof ridge cape roll forming machine technology white area and small cracks might exist in the contact of the melt to the roll. Thickness at roof ridge cape roll forming machine technology white area is thinner than other area while cracks can be observed at white area or at grain boundary in the chill structure. Elimination of small columnar roll forming machines structure in the roof ridge cape roll forming machine technology at chill area might be useful to get rid of small cracks.
By doing so, the grooved roll can be better adopted to improve the roof ridge cape roll forming machine technology white area and small cracks. In the present study, the shape of the roof ridge cape roll forming machine technology bulge can be formed on the strip surface and the rotation of the roll can be stopped in the course of operation. In roof ridge cape roll forming machine technology, the bulge on the strip surface as well as the height of the bulge can be rather low. Melt might be inserted in the groove according to roof ridge cape roll forming machine technology by the melt head in its contact to the roll.
Therefore, the melt cannot fill the groove, and the height of the bulge in roof ridge cape roll forming machine technology is lower than the depth of the groove so the melt could not insert fully in the groove by the surface tension. When the roof ridge cape roll forming machine technology load is given by the roll, metals that are inserted in the groove deeply might be roll formed in a quick manner to be very thin and narrow. When the strip is formed using roof ridge cape roll forming machine technology, strip surface might be semisolid condition as the melt will not contact to the roll in a direct manner. The white area of the strip casted by the flat roll roof ridge cape roll forming machine technology is thin when the grooved roll is used and dragged by the roll. This is also true when the roof ridge cape roll forming machine technology meniscus becomes large since the contact condition between the melt and the roll might be better at the white area than other areas in the roll forming machines.
