well controlled particle size reduced sponge iron powder for flame cutting

Normally,a typical oxy-fuel flame cannot generate sufficient heat to cut materials such as stainless steel due to the formation of heat resistant slag. Powder cutting, in which iron powder is added to the flame, has a twofold effect. Firstly, the burning (oxidation) of the iron powder provides a higher cutting temperature. Secondly, the heat-resistant slag is diluted by the oxidised iron powder, causing a decrease of the slag melting temperature. This results in a more fluid slag that can easily be removed by the oxygen stream
