Enamelling Furnace Characteristics and Working Principle

Enamelling Furnace Characteristics and Working Principle

Enamel furnaces is a metal furnaces with enamel coating on its surface. Here are some introductions about enamel furnaces.

Enamel furnaces characteristics:

High temperature resistance: Enamel coating is made of silicate mineral raw materials melted at high temperatures, which can withstand high temperatures and resist high-temperature oxidation.

Corrosion resistance: It has excellent chemical stability and can resist the corrosion of chemical substances such as acid and alkali.

Easy to clean: The enamel surface is smooth, not easily stained, and easy to clean.

Enamel furnaces working principle:

Enamel furnaces themselves are usually not an independent type of heating equipment, but rather use enamel materials for the furnace body or related components based on some heating furnaces. Taking the common enamel firing furnace as an example, its working principle is as follows:

Heating method: It can be divided into burner type and electric heating type in terms of heating method. The burner type generates heat by burning fuels such as gas, and the heat is transferred to the furnace through devices such as radiation tubes, which heats the enamel products; Electric heating type uses heating elements such as resistance wires to generate heat by passing electricity.

Temperature control: In order to ensure a tight bond between enamel coating and metal surface and guarantee quality, it is necessary to precisely control the temperature inside the furnace. Real time monitoring of furnace temperature through temperature sensors and feedback of signals to the control system. The control system adjusts the heating power or gas supply of the burner based on the difference between the set temperature and the actual temperature to achieve precise temperature control.

Enamel furnaces application:

Enamel furnaces are widely used in industry, mainly including the following aspects:

Chemical industry: used for manufacturing enamel reaction vessels, enamel storage tanks, enamel pipelines and other equipment. The enamel furnace uses high temperature firing to tightly bond the enamel coating with the metal surface, forming an enamel layer with good corrosion resistance, wear resistance, and high temperature resistance. It can resist the erosion of various chemicals such as acids, alkalis, and salts, ensuring the safety and stability of the chemical production process.

Food industry: can be used to produce enamel cooking utensils, such as enamel pots, enamel plates, etc., as well as food storage containers. These enamel products are non-toxic, odorless, wear-resistant, with a smooth surface and easy to clean. They can effectively prevent food from coming into contact with bacteria and dirt, ensuring food safety. At the same time, they can also withstand the corrosion of acid, alkali, salt and other components in food, maintaining the quality of food.

Pharmaceutical industry: Pharmaceutical equipment such as enamel reaction vessels and enamel evaporators are often produced using enamel furnaces. Its acid and alkali resistance and corrosion resistance can prevent contamination of drugs during production, ensuring the purity and quality of drugs. In addition, enamel medical instruments such as surgical handles and medical instrument trays have the characteristics of sterility and easy cleaning, which can ensure medical safety.

Metallurgical industry: Enamel crucibles can withstand high temperatures and corrosive substances during metallurgical experiments and production, ensuring smooth metallurgical processes. Some high-temperature resistant enamel products can also be used to manufacture steel production equipment such as ingot molds and continuous casting crystallizers, which helps improve steel production efficiency and product quality.

Environmental protection field: Enamel wastewater treatment equipment, with its acid and alkali resistance and wear resistance, can effectively treat wastewater and reduce environmental pollution. In some environmental protection projects, enamel pipes are also commonly used to transport corrosive wastewater or exhaust gases.
