Tackling the basics of powder cutting

Updated: May 30

In the realm of demo and cutting technologies. Powder cutting has emerged as an effective method that has been shaping industries for decades. This method relies on using iron powder to increase the temperature of the flame. If you're new to the world of metal cutting, we will guide you through the basics of powder cutting, breaking down the process in simple terms. 

 

What is powder cutting?

 

The term powder cutting is used within the metallurgical industry. For various types of flame processing of high alloy and heat resistant metals. Including steel, stainless steel and cast iron. Typical oxy-fuel flame cannot generate enough heat to cut these materials due to the formation of heat-resistant slag. 

 

Power cutting is a technique where iron powder is added to the flame. This increases the temperature allowing the metal to be cut. Heat-resistant slag is diluted by the oxidised iron powder causing a decrease of the slag melting temperature. Giving you a more fluid slag that can be easily removed by the oxygen stream.

 

This technique is more than often used in heavy-duty industries such as stainless steel mills, furnes and scrapyards. The majority of this is used in stainless casting with fume extraction and scrap-cutting ferrous metals that are usually completed outside.

Alternatives to powder cutting.

 

Powder cutting isn’t as popular as it once was with developments in technology and more concern over the environment around us this has changed. Other options are suitable to achieve the same job or even achieve better.

 

Thermit lancing is a cost-effective and versatile way of cutting and boring stubborn materials. The lance, When activated, the thermit lance engages in a thermo-chemical reaction, effectively melting a wide range of materials.

 

The process of hot cutting exothermic reaction generates temperatures that are often over 4000°C. Its effectiveness stems from its uncomplicated usage and minimal equipment prerequisites, making it a highly adaptable tool.
