Flame Gas Cutting Machine

Firstly, what is flame cutting? Flame cutting is a heat-cutting process that uses pure oxygen and fuel gas to cut metals.

The heat generated by oxygen fuel torches is used to heat the steel surface or edge to about 1800 degrees.Oxygen then flows into the heated area through fine, high-pressure currents, forming an empty hole. The heat and oxygen flow move at a consistent speed, cutting the metal.

Secondly, what is the gas in flame cutting? The most common are propane, acetylene, and liquefied petroleum gas. Depending on the flame temperature and heat distribution, the gas type affects factors such as cutting mass, piercing time, and cutting speed.

The following factors may influence your choice of a particular fuel gas:
Acetylene: The flame temperature produced by ethylene is the highest of all fuel gases.It leads to faster piercing. It also produces a more intense flame, reducing the size and deformity of the thermal impact zone (HAZ).
Propan: Propan has a lower flame temperature than ethanol.Thus, the perforation speed is slower than that of ethanol; however, the cutting speed is roughly the same.
Liquefied petroleum gas product: Its flame temperature is similar to Propan. The principle of its operation is to concentrate the heat on the outer edge of the hot tubes.

Flame cutting is the most cost-effective process of carbon steel cutting.The following are the steps of its work:

Step 1: Preheating
The preheated flame of an oxygen fuel torch is used to heat the steel to its ignition temperature, about 1800 degrees.Then it can react with oxygen.
During this process, the fuel-oxygen ratio can be adjusted. This will help to produce the highest possible temperature with as little flame as possible.This increases control, and heat can be concentrated on a small area of the steel plate surface.

Step 2: Punch
The piercing refers only to the initial piercing of the cut surface; once the surface or edge of the plate reaches the ignition temperature, the oxygen will start to flow and start to penetrate the plate.

Step 3: Cut
After cutting the oxygen stream through the steel plate, the torch can begin to move at a constant speed. This leads to continuous cuts.

While these are fundamental steps in the process, many other factors are playing a role.These include speed, cutting oxygen pressure, pre-heated flame adjustment, cut height, and steel plate temperature. Each of these factors affects the final quality of the cutting edge and determines whether the flame-cutting operation will be successful.
