The volume of low -rise and private construction increased at the present time has increased demand, both for building materials and roofing in particular. Many future tenants of the houses erected want to have an original look of their building with the original look and relatively inexpensive roof of their building.
It is for this reason that the production of metal tiles becomes the most promising choice. Metal tile – roofing material made of galvanized steel with further application of the protective coating. The external coating of the metal tile can be painted in different colors. The metal tile combines the strength of steel and the aesthetic type of clay tile.
Technological manufacture of metal tiles requires certain equipment. The line for the production of metal tiles includes: a roll of rolled metal, a rolling mill, a knife guillotine, a reception table, as well as a control system.
The unwound of rolled metal consists of a bearing base and collapsible coil. These machines are quite easy to operate. After installing a coil with rolled metal on the base of the machine, unwinding is carried out directly by rotating the coil mechanism with further supply of metal to a rolling mill. When choosing this equipment, it is necessary to take into account the factor that rolons with metal can come of different masses.
Therefore, it should be purchased to unwind metal with a supply of load capacity. The recommended lifting capacity of the unit should not be less than ten tons. Equipment performance depends on many factors. Orders enter the manufacture of profiled flooring of different colors, so you often have to change the rolls of metal. The most significant factor in the downtime of production is the speed of replacement of rolls.
The rental camp performs the transportation of the workpiece of metal tiles at all stages of production. The installed roller rolled machine betray the required shape of the metal. One of the important differences in the design of the rolling mill offered by manufacturers is the installation of rollers creating a cage (the shape of the manufactured metal tile). With a key attachment (which is a connection of the shaft with the roller using a key) the design of the tick is more reliable and accurate.
This affects the greater price of the equipment, since the shaft has complex geometry and there are bushes, nuts, and kins in the design. When fastening the rollers with a “wedge” – the mechanism of the construction of the tick has a shorter service life, since the rollers on the smooth shaft are fixed with a screw that is rapidly wear out. This method, although it costs approximately one and a half times cheaper, will cause difficulties with setting up the camp.
A high -quality line for the manufacture of metal tiles should have a clear geometry of the profile of corrugated board. When rolling metal of various thicknesses, the shaft should have good stiffness. In its absence, the deflection of the shaft is possible, which will lead to an uneven depth of corrugation at the edges and in the middle. Accordingly, there can be no question of any clarity of the geometry of the resulting profile of the metal. The experience of the production and operation of rolling equipment showed that the diameter for rollers for the rolling mill should be at least ten centimeters. Otherwise, the shaft may deform and fail.
Naturally, in the manufacture of metal tiles, an important factor is the speed at which the metal is supplied to the line of the rolling mill. Standard equipment of the metal line in particular – the electric drive, as a rule, is installed asynchronous. This drive can supply metal to the shafts at a speed equal to twenty -two meters per minute. When improving and replacing an electric drive with a servo drive, you can achieve an increase in speed to forty meters per minute. In addition, on the line with such a drive, the accuracy of stamping steps increases.
When buying equipment for corrugated board, you should visit the production of this equipment. The conscientious manufacturer of equipment has nothing to hide and he will show you everything regarding the quality of the purchased equipment.
