Industrial Furnaces Industry Information

Industrial Furnaces

Industrial furnaces are enclosed structures that contain high heat chambers. Compared to industrial ovens, industrial furnaces provide much higher temperatures and are mostly used on materials with high melting points.

Quick links to Industrial Furnaces Information

Applications of Industrial Furnaces

Industrial furnaces are found in any metallurgy application involving the use of heat to alter, improve, fabricate, or form metals like steel, titanium and aluminum, alloys, glass, composite materials, and some plastics.

They are commonly used in these processes and environments:

  • Glass Fabrication
  • Steel Service Centers
  • Foundries
  • Forgeries
  • Metal Recycling Plants

Their most common use is for heat treating glass and metal, which alters or improves the material's properties by exposing it to high temperatures, then rapidly cooling it. Furnaces are also capable of aging, annealing, sterilizing, and sintering materials, as well as melting raw substances for molding or casting purposes.

Industrial Furnace Design and Customization

Furnaces meant for small runs are usually of single chamber design and are manually loaded and unloaded with various tools to lift crucibles full of molten metal or heat treated products. Larger volume furnaces have automated conveyor systems that allow many parts or products to be treated at a time. Their controlled atmospheres can be oxidizing, inert, salt bath, or vacuum. Furnace specifications include temperature requirements, pressure, internal width, length, and height, as well as heat source.

Industrial Furnace Classifications

There are many different furnace heat sources available today. They include radiant, natural gas, induction, conduction, electrical, and dielectric. Each method has specialized benefits, limitations, and applications. Radiant heat furnaces are similar to wood stoves and portable heaters. They use a flame to heat an object, commonly a ceramic plate. This object gives off heat that transfers throughout the area. Natural gas furnaces are very common. Compared to electric furnaces, they are an economical method of creating a high heat environment. They burn natural gas or propane to generate heat and are used for their high temperature abilities.

Induction furnaces use a combination of electrical resistance and hysteresis losses to heat metal parts. They are exposed to a magnetic field around a coil-carrying alternating current. Induction furnaces are the first choice in metal melting applications and are often used by iron foundries. Electric furnaces are also popular for melting metal. The most common type is an electrical arc furnace, which uses high amounts of electrical current, which travels through a metal arc and is conducted onto large amounts of scrap metal. The current heats the scrap metal to a high enough degree to melt it completely. These furnaces are mostly used for recycling metal parts to be formed into new products.

L&L Special Furnace Co., Inc. has received an order for two atmosphere controlled retort box furnaces used for de-bindering ceramic composite matrix parts, (CMC) along with powder medals processing (PM) and hot isostatic processing (HIP). Initially CMC and other ceramic matrix components and additive manufactured parts were developed for bullet resistive armor and cloth. These materials were found to be lighter and stronger than some alloy and ceramic substitutes. Additive manufacturing and CMC materials are now becoming more routine and are finding their way into more and more widespread industries.... Read More About This
