Two-Coat-One-Fire Enameling System (3) - Wet-to-Dry Process
2.3 Wet-to-Dry Process
A ground coat slurry containing an adhesive is applied by spraying or dipping, then allowed to dry completely. Subsequently, a dry powder enamel is sprayed onto the dried ground coat using electrostatic spraying.

Two-Coat-One-Fire Enameling System (2) - Dry-to-Dry Process
2.2 Dry-to-Dry Process
The ground coat powder containing an adhesive is applied to the surface of the substrate by electrostatic spraying, followed by spraying a powder cover coat enamel; no drying is required.

Two-Coat-One-Fire Enameling System
The development of the pickling-free bonding ground coat and the two-coat-one-fire enamel frit in 1980 was the first breakthrough in enamel technology. This process not only broadened the range of steel plates used for enamel but also resulted in excellent adhesion after firing.

Cast Iron Enamel Pre-treatment
Before enamel coating, castings should undergo surface grinding, firing, and sandblasting to clean them.
During the casting process, castings inevitably have some casting defects such as mold seams and loose sand. These require manual cleaning and grinding to achieve a smooth and even surface.

The Advantages of Large-scale Continuous Mechanical Enamel Furnace
The Advantages of Large-scale Continuous Mechanical Enamel Furnace are:
(1) Wide range of product types and sizes. Small products can be fired in baskets, divided into 4-7 layers, while larger products can be used for bathtubs or water heater liners, etc.

Large-scale Continuous Mechanical Enamel Furnace
2.3 Large-scale Continuous Mechanical Enamel Furnace.
This type of furnace is characterized by a large firing chamber cross-section, with a height ranging from 1.7 to 2.5 meters (some are lower, some higher, depending on product size and output).

Currently, enamel furnaces can be basically divided into three types:
2.1 Box furnaces
Products enter and exit through a single doorway, manually using tools. The size of the furnace chamber is determined by the size of the products and the desired output.
