Introduction to the Semicircular Glazed Tile Roll Forming Machine in Nigeria
The **Semicircular Glazed Tile Roll Forming Machine used in Nigeria is specialized automated equipment designed for producing semicircular glazed tiles (commonly referred to as "Spanish-style" or "S-tiles"). This type of machinery is critically important in Nigeria and other African building material markets, as glazed tiles are highly sought after for their aesthetic appeal, durability (weather and rain resistance), and compatibility with traditional architectural styles
Key Features of the Machine:
1. Core Functionality:
Transforms coiled galvanized steel orpre-painted steel sheets (base material) into a specific semicircular profile through a series of precision-engineered rollers.
During or after forming, applies a glazed coating(vitreous enamel) to the steel surface and cures it via **high-temperature baking**, creating a glossy, waterproof, and weather-resistant glazed layer. This distinguishes glazed tiles from standard color-coated steel sheets.
2. Main Components:
Uncoiler: Holds and unwinds the steel coil.
Feeding Guide System: Ensures smooth and accurate sheet entry into the main unit.
Roll Forming Main Unit:
The core section, containing multiple (typically 10-20 or more) carefully designed roll stands.
Each set of rollers progressively bends the flat sheet into the final semicircular cross-section. The roll profile design determines the tile's precise shape (curvature, wave height, overlapping edges, etc.).
Glaze Application System:
Applies a uniform layer of specialized glaze slurry (composed of inorganic pigments, glass frit, binders, etc.) via spray guns or roller coating equipment, typically during the mid or late stages of forming or post-forming.
Baking/Curing Oven (Glaze Kiln):
Glazed tiles immediately enter a **tunnel-type baking oven.
Heated by gas (natural gas, LPG) or electricity, the oven rapidly melts, levels, and cures the glaze at high temperatures (typically 200°C - 300°C+, depending on the glaze formula), forming a hard, smooth, durable vitreous surface tightly bonded to the steel substrate.
Cooling System:** Baked tiles pass through a cooling section (usually air-cooled) to reach a safe handling temperature.
Cutting Unit:** Precisely cuts the continuously formed tile strip to set lengths (usually the effective length of a single tile) using hydraulic flying shears or pneumatic cutters.
Output Rack/Stacker:** Automatically stacks finished glazed tiles neatly for bundling and transport.
