Porcelain Enamel Parts for Stove

 In the early days, stoves were heated with charcoal, but now they use cleaner liquefied petroleum gas or electricity. Since the burning part of the stove grill and the food-contact parts must withstand the high temperature during food processing, it must also be stable during use and will not decompose toxic substances. At the same time, the entire grill parts must be easy to clean after grilling, so Enamel materials have become the best material of choice.

Outdoor gas grills, the whole product is mainly divided into stove cover, stove body, grilling net, combustion system and support. The main parts of stove cover, stove body and grilling net that are exposed to high temperature are made of enamel materials.

The grill body is mostly made of high-quality low-carbon steel plate of 0.5~1.0mm, and the grilling net can be formed by wire welding or cast iron casting.

There are many coating methods for gas stoves. Most small charcoal stoves use manual dipping, and large gas stoves, especially parts with more than three burners, are mostly sprayed. Because large parts have many mounting holes and corners, it is difficult for the enamel frit to be evenly coated on the entire surface, which affects the overall product appearance.

The thickness of the base material of the enamel parts of the mainstream stove grill is 0.5~1.0mm, the firing time is mostly 3~5min, and the firing temperature does not exceed 860℃. The firing temperature of the cast iron bakeware and grilling net is below 760℃, and the firing time depends on the volume and thickness of the casting, generally no less than 12min.

The food safety requirements of the enamel parts used in the grill lock are relatively strict. Most of them use the European Union's Rohs and the United States' FDA standards, mainly for the chemical composition.

The main part of the grilling operation in the furnace body also bears the high temperature and rapid temperature changes during grilling. All these parts need good heat resistance and temperature sudden change resistance.

There are many differences in the assembly of gas and charcoal grills. The components used in gas require strict safety inspections before they can leave the factory. Most of the charcoal stoves are shipped in loose parts, and the user assembles them according to the instruction manual. Regardless of the method used, the assembly of the enamel parts must be very careful, as far as possible, it is not necessary for the user to do too many operations on the enamel parts that may cause damage to the enamel layer.
