Oxygen cutting

The essence of the technology of splitting metal materials with an oxygen flame is the process of burning iron heated to ignition temperature in a stream of oxygen. The cut material is burned (combined) with cutting oxygen to form oxides, which are blown away in the form of liquid slag by the dynamic effect of oxygen from the cutting site. The combustion process, in which various types of iron oxides are formed, is a significantly exothermic reaction, i.e. with a large heat generation at the point of cutting. At the beginning of the process, it is necessary to heat the material at the beginning of the cut to an ignition temperature, in the second phase, oxygen is introduced under high pressure, which burns the iron particles and blows the molten metal out of the cutting joint. oxygen flow.

Modern, precise and powerful CNC firing machines from the manufacturers MESSER and MGM are intended for the production of blanks primarily from non-alloy structural steels, steels for refining and boiler steels in thicknesses from 3 to 250 mm at max. table dimensions 3.5 x 16 m. Bevels are fired on a double-burner head when burning strips, or additionally with the RS 13 firing device for shaped firings.

• The quality of the material is determined by the customer according to the supplied drawing documentation, and it is possible to provide a material certificate for any firing plan or fired pieces.
• Burns are supplied with a surface according to EN 10 163, thickness according to EN 10 029
• Dimensional tolerances of shaped blanks are according to STN EN ISO 9013 II B
• The quality of the cutting surface is guaranteed according to STN EN ISO 9013 II. Local defects of the cutting surface are not taken into account in the assessment.
• Painting and blasting of fired pieces can be arranged separately. If the pieces have the following bending operation prescribed, they will be automatically blasted.
• The standard delivery time for material in stock is from 3 to 10 working days after order confirmation. Express orders are possible for an additional fee. Delivery parity EXW manufacturer. Upon agreement, it is possible to import by transport PMR, s.r.o. to the destination.
