KBA-MetalPrint glazing line

The main components of the glazing line are ф glazing machine and drying oven. At first sight, the equipment seems to be simple and uncomplicated. Even those who have ever tried to make a copy of these lines failed to build a line that could be identical in the functions, technical parameters, capacity, glazing quality, power consumption and environmental friendliness. A seemingly simple operation of applying a thin film of glaze to a tin or aluminium sheet is actually a very complicated processing phase which has a direct impact on the metal sheet behavior in further treatment.

Today, the metal glazing process must meet very high requirements:

  • A liquid glaze film must be as thin as possible;

  • The spaces - transversal or longitudinal clean strips required for further cylinder welding - must remain ideally clean and be at the same place of the sheet;

  • The amount of gas burnt to heat the oven tunnel must be as little as possible to save the expenditures;

  •  

     

  • The solvent which makes nearly half of the glaze must be disposed during the glazing process; this, on the one hand, saves the heating gas, and, on the other hand, protects the environment against a vapour harmful impact;

  • The equipment, first of all, the glazing machine, must suffer minimum deterioration, bearing in mind that modern glazes are rather corrosive;

  • Switch between different types of  glazes, both in the glazing machine and in the oven operation program, must be as quick as possible, without causing a "blockage" in the production schedule;

  • Temperature in the oven tunnel shall be adjustable as required by the glaze manufacturer. To make the glaze properly dry, it is very important to maintain the temperature curve when the metal sheet passes the tunnel; the temperature must be evenly distributed over the sheet surface.

etc...

 

The new KBA-MetalPrint glazing machines - 470 and 480 meet these requirements in full, and the afterburner s produced since 2008 for ECO ovens open new possibilities for gas saving.
