Role Of LPG In the Metal Industry

The metal industry is one of the most energy-consuming industries. The rise of metal melting is increasing for the lighter metal casing which is useful in automotive, appliances, and aircraft.

There is no surprise that metal melting industries are looking for an efficient fuel source to reduce cost and increase productivity. You can source LPG gas from a private gas agency to suffice the needs of the metal industry.

Conventional Fuels in Metal Industry

(i)Light fuel (ii) Light diesel oil (iii) High-speed diesel Irrespective of their usefulness, these fuels are not efficient for the metal industry. It leads to several disadvantages.

Disadvantages of Using Conventional Fuels

  • Non-uniformity in temperature control
  • Greenhouse gas emission
  • Takes a long time for ignition and metal melting, cutting, or molding.

Many ferrous and non-ferrous metals are treated in metal foundries by diecasting the metal and then injecting it into molds to give it the desired shape.

In the metal industry, heat treatment involves heating and cooling of metal for making alloys or modifying the physical properties of the alloy. This process is called annealing.

Useful In Annealing Process

The heat treatment of anodizing increases ductility and reduces the hardness of metals. It changes the physical properties of the metal, sometimes chemical properties too.

Annealing is mostly done in long ovens where temperature control needs to be precise, here LPG is useful in fine temperature control.

Useful in Metal Cutting

LPG is mixed with BF (Blast Furnace) gas which has a lower CV value, for cutting steel or any other metal. The melting point of aluminum is 660.3 °C (1200 °F), the melting point of gold is 1064.18° C, and the melting point of tungsten is 3,422 °C, LPG gas is useful in generating high temperatures for cutting metal with a high melting point.

LPG provides a stable high temperature for making clean cuts. LPG ensures homogenous cutting of metals due to its constant temperature control.

Heat Treatment

Heat treatment is one of the essential parts of metal manufacturing. It ensures the metal can withstand wear and tear, making it durable in long run. The meaning of heat treatment is heating and cooling the metal several times until the desired properties are obtained. In this, the shape of the metal remains intact.

LPG is useful in controlling the right temperatures in the furnaces. The heating process requires a temperature up to 2400 °F. As LPG is a clean fuel and has a high calorific value it can easily burn up to 2400 °F.

Advantages of LPG gas in the Metal Industry

LPG does not produce smoke or any harmful toxic gas while burning. It reduces the emission of toxic gases into the air. Moreover, LPG does not leave a residue of sulfur, carbon, or lead. This ensures there is no scaling on the metal and prevents the metal from overheating during melting or molding.

LPG private gas agency provides lower-cost commercial gases that are preferable for the metal industry, to reduce the operational costs.


In today's business climate, companies that manufacture thermal processing systems must increase productivity, reduce setup costs, improve product quality, and reduce carbon dioxide emissions.
