Enamelled steel
Enamelled steel, often also called "enamelled sheet" or "emaile," is a special type of material that combines the properties of steel with those of glass. The production of enameled steel is a technically demanding process, which includes placing glass on a steel substrate and a subsequent high-temperature hardened phase. Here are some key aspects regarding enamelled steel:
Manufacturing process:
Steel substrate: The starting material is steel plate, which is often used in construction and industrial production. This sheet must be clean, free of grease and other impurities.
Surface preparation: The surface of the steel substrate is carefully prepared. This includes cleaning, removing dirt and applying a special enamel layer that will serve as a base for the enamel.
Application of glass: After preparation, glass powder or suspension is applied to the steel substrate. This process can be done in a number of ways, including electrostatic spraying or dipping.
High-temperature hardening: The product is then exposed to extreme temperatures that reach thousands of degrees Celsius. This phase of the process ensures the bonding of the glass to the steel substrate and the formation of a hard, durable and resistant surface layer.
Advantages of enamelled steel:
Resistance to corrosion: Enamelled steel is extremely resistant to corrosion and chemical aggressive substances. Therefore, it is often used in the production of chemical storage containers, water tanks and sewage systems.
Resistance to mechanical damage: Enameled steel has a hard surface, which makes it resistant to damage and abrasion.
Hygienic properties: It is easy to maintain and has a smooth surface, which makes it hygienically suitable for applications in the food industry and in the health sector.
Aesthetic appearance: Enameled steel is available in a variety of colors and can have an aesthetically pleasing appearance. It is used for the production of enameled household appliances, such as hobs and sinks.
Resistance to high temperatures: It has the ability to withstand high temperatures, which makes it suitable for applications where thermal insulation or fireproof properties are required.
Long service life: Enameled steel has a long service life and is resistant to wear.
Ecological purity: It is ecologically friendly because it does not contain harmful substances and is 100% recyclable.
However, it should be noted that the production of enamelled steel is expensive and technically demanding, and therefore this material is often more expensive than other alternatives.
