In the enamel manufacturing industry, metal pretreatment is a crucial process, which directly affects the quality of the enamel finished product. Whether it is an enameled steel plate or a cast iron billet, pretreatment is required. It is worth mentioning that stainless steel enamel also requires stainless steel pretreatment. Stainless steel enamel needs to be sandblasted to roughen the surface of the body and improve the close adhesion between the enamel layer and the enamel layer.
A customer once tried to make stainless steel enamel by himself, but the adhesion of the finished product was not good. However, both the enamel manufacturing process and the quality of the enamel frit and stainless steel were confirmed to be correct. After in-depth investigation and testing by our technical staff, we found that the cause was the lack of metal pretreatment. After sandblasting pretreatment, the adhesion of the enamel finished stainless steel products is significantly improved, meeting the customer's expectations.
Taking steel plate enamel as an example, the metal pretreatment process is equally rigorous. First, the steel plate workpiece needs to be soaked in a degreasing liquid at 55 to 65 degrees Celsius for 15 to 30 minutes to completely remove oil stains on the surface. Next, the remaining liquid on the surface of the steel plate is thoroughly cleaned by water washing to ensure that no impurities remain.
Then comes the rust removal process, where the steel plate is soaked in a rust removal solution at 50~60°C for 10~15 minutes (the specific time depends on the rust on the surface of the steel plate). This step is to remove rust and oxides from the surface of the steel plate and ensure that the enamel layer can be evenly and firmly attached to the metal substrate. After rust removal, wash again to ensure the surface of the steel plate is clean.
Finally, the steel plate is neutralized to ensure that every part of the steel plate workpiece is immersed in the neutralizing solution to neutralize the remaining acid and alkali substances and prevent adverse effects on the subsequent enamel layer. After the neutralization is completed, the steel plate workpiece is naturally air-dried to prepare for the subsequent enameling process.
Although pre-treating enameled metal may seem simple, every step is crucial. It not only improves the quality of finished enamel products, but also extends the service life of the product. Therefore, as an enamel manufacturer, you should attach great importance to the metal pretreatment process and ensure that every step is operated in strict accordance with standards.

What is the difference of porcelain vs enamel on steel tubs?
Porcelain is a type of ceramic; it is not part of a steel tub. If the tub were made of porcelain it would not be made of steel. Enamel is a kind of tough paint that can be used on steel, or on porcelain.
Does enamel paint stick to stainless steel?
Yes it does.
What is pretreatment?
Pretreatment is done before washing or cooking. Anything that takes place before either washing or cooking is considered a pretreatment.
What is the composition of enamel used in cookware?
Most enamel pots are steel with an enameled finish. Target, for one place, carries a number of styles of pots in different colored enamel finishes.
Is your painted steel bowl oven safe?
A painted steel bowl is oven safe, as long as the paint is enamel.
How do you enamel a wood burning stove?
Some wood burning stoves are made of enameled steel, but the enamel is applied at the factory. The enamel is actually a form of glass, which is applied to the steel as a powder and then melted and fused on in an oven or kiln at a very high temperature. It is not the kind of thing that can be done in the home.
Which of the cooktop finishes on the GE JP202 (White enamel or stainless steel) is more resistant to stains -- particularly rust stains?
Stainless steel is more resistant to stains,particularly rust stains,than white and enamel on the GE JP202.
What is better Stainless steel vs enamel cook top?
Personally I prefer stainless steel due to the fact that you can clean it with boiling water, and you don't really need to worry about cracking. Enamel ware can crack from temperature change and can get scratched easily
What is the difference between cast iron and steel enamel (from the perspective of enamel frit)?
To understand the difference between cast iron enamel and steel plate enamel, we must first know the difference between cast iron and steel plate. Both steel and cast iron are iron-carbon alloys, and the distinction between these two metallic materials is mainly based on carbon content. The cast iron generally used in enamel is gray iron or gray cast iron, and the carbon content is usually 3%~3.7%, while the carbon content of refined iron (low carbon steel cold-rolled sheet) is less than 0.12%, which means that cast iron contains more than steel plate. More impurities, when sintering, are more likely to generate carbon dioxide and other gases, resulting in enamel defects such as pinholes, air bubbles, and pores on the porcelain surface. Therefore, in the selection of enamel frit, cast iron enamel frit needs to meet the following conditions: low temperature firing, to avoid oxidation and decomposition of iron carbide in cast iron, and release carbon dioxide; good adaptability, which is conducive to gas in the early stage of firing It has good sealing performance, and does not allow gas to break through the porcelain layer and cause defects in the later stage of firing. Therefore, the formula design of enamel primer is very different from that of steel plate primer. For example, the firing temperature is generally 760~780℃, which is obviously lower than the high temperature of 850℃ of steel plate primer. At the same time, the addition amount of cast iron frit in borax, feldspar and other raw materials is larger than that of steel plate enamel frit, the purpose is to reduce the viscosity of the enamel frit, improve the wettability, form small pores and accommodate the gas discharged from the matrix, and improve the solubility of iron oxide. The formula design of cast iron enamel frit and steel plate enamel frit is very different, in order to meet the needs of enamel enamel frit for the corresponding material to the greatest extent.
