Mesh chain sintering furnace

Equipment Application:

The firing furnace with mesh-belt conveyor is designed for smelting the printed front and rear electrodes onto the PN junction layer. This process forms an ohmic contact, enabling the electrical energy collected by the thin grid lines of the cell to flow out through the main grid lines. It plays a crucial role in the production of solar cells, ensuring efficient energy conversion.

Process Flow:

The process flow of the firing furnace typically includes drying, pre-sintering, main sintering, and cooling stages. During drying, moisture is removed from the electrodes to prepare them for sintering. Pre-sintering involves heating the electrodes to a specific temperature to initiate the sintering process. Main sintering is where the electrodes are heated to the required temperature for the sintering reaction to occur effectively. Finally, cooling helps to stabilize the sintered electrodes and prevent thermal shock.
