The present disclosure discloses a sintering furnace including: a furnace chamber comprising a plurality of processing zones; a conveying device disposed within the furnace chamber and extending along a conveying direction, the conveying device configured to convey a processing element through a plurality of processing zones of the furnace chamber; and at least one temperature measurement device connected to the furnace chamber, the temperature measurement device configured to detect the temperature of the processing element in the furnace chamber and provide temperature data. The present disclosure directly detects the temperature of the photovoltaic device in the sintering furnace through a temperature measurement device, rather than detecting the temperature of the gas in the sintering furnace, for more directly controlling the amount of heat or cold absorbed by the photovoltaic device in various processing areas of the sintering furnace, thereby improving the yield of the product.

The present disclosure relates to a status monitoring system and control method for a mesh belt furnace for ceramic sintering. The system includes an acquisition layer, an analysis layer and a regulation and control layer. Image data of products conveyed in the mesh belt furnace is acquired by the acquisition layer, and acquired product image data is further segmented to obtain product images. The analysis layer synchronously receives the product images obtained by segmentation in the acquisition layer, and analyzes a product sintering status corresponding to each group of product images based on the product images. Image data acquisition on sintered products in the mesh belt furnace allows primary data to be provided for monitoring an operation status of the mesh belt furnace; then analysis based on the acquired product image data allows to determine qualification of output products in the mesh belt furnace and evaluate overall quality thereof.

A heat treatment furnace disclosed herein may include: a heat treatment unit configured to heat-treat an object; a cooling unit configured to cool the object heat-treated by the heat treatment unit; and a conveyor configured to convey the object in the heat treatment unit and the cooling unit. The cooling unit may include a housing, wherein the housing is disposed below a conveyance path on which the object is conveyed by the conveyor and configured to cool the object being conveyed by the conveyor by liquid flowing inside the housing. The housing may include an upper plate facing the object being conveyed by the conveyor. The upper plate may be tilted so that gas stays at a predetermined portion of the housing while the liquid is flowing in the housing.

The present application provides a furnace chamber for a reflow furnace, the furnace chamber including a high temperature zone and a cooling zone, the cooling zone including: a base plate provided with a through hole; an airflow source provided above the base plate, which delivers airfl 5 ow to the base plate and delivers airflow through the through hole on the base plate, wherein the base plate includes a bottom surface facing away from the airflow source, at least a portion of the bottom surface being arranged at an angle to a horizontal direction of the furnace chamber, the cooling zone being provided with a processing area, and the bottom surface of the 10 base plate being inclined to at least one side of the processing area along a conveying direction of a circuit board. A flux condensed on the bottom surface flows along a ramp to a lower edge of the base plate. The base plate is located above the processing area, and the lower edge of the base plate is located in an area other than the at least one side of the processing area, as viewed from the top down. In 15 this way, the flux condensed on the bottom surface of the base plate flows along the ramp to the lower edge of the base plate, out of the lower edge and dripping to an area outside at least one side of the processing area without dripping onto the circuit board of the processing area.

A vertical-type firing apparatus for a positive electrode material for a secondary battery, for vertically moving and firing the positive electrode material for the secondary battery, comprises: a vertical-type firing furnace including an exhaust part, an air supply part, and a firing space positioned between the exhaust part and the air supply part; and a heater for heating the firing space of the vertical-type firing furnace, wherein the firing space includes a temperature-raising space, a cooling space, and a temperature-maintaining space located between the temperature-raising space and the cooling space, and the temperature of the temperature-maintaining space is higher than the temperature of the temperature-raising space and the temperature of the cooling space.
