Micro Computer Controlled Dual Disc Infrared Dryer Moulding Sand Testing

Micro-computer controlled dual disc infrared dryer QR-SHG

Product details:
In wet casting production, the moisture content of the molding sand should be in a relatively suitable state. The suitable moisture content of molding sand is mainly influenced by the amount of mud content. In addition to the mud content of the raw materials used, it is also necessary to consider the continuously generated mud during the casting process, such as clay turning into dead clay after high temperature, coal powder turning into ash after burning, which increases the mud content in the molding sand. This will cause a change in the originally suitable moisture content of the molding sand. In order to facilitate molding, it is often necessary to increase the moisture content of the molding sand. The performance of molding sand often changes during the production process, especially in large-scale assembly line production.
The moisture content of molding sand is highly sensitive to changes in its properties. If the moisture content is too high, the flowability of the molding sand is poor, the molding sand is not easy to compact, and the wet strength of the molding sand is relatively low, which can easily cause surface roughness, sand swelling, sand inclusion, flame running, porosity and other defects in the casting, and difficult sand falling. Wet molding sand is also prone to sticking to sand and hoppers, which poses difficulties for molding. On the contrary, if the moisture content is too low, the toughness of the molding sand is poor, the mold is difficult to take, the surface strength of the sand mold is poor, and the casting is prone to defects such as sand flushing and sand holes. Therefore, in the production process, it is necessary to correctly select and control the appropriate moisture content of the molding sand based on objective factors.
(1) Main performance of the instrument
This dryer is designed for rapid drying when using a microcomputer controlled digital display to measure the moisture content of sand samples (original seconds, mold seconds, and core sand). The system utilizes infrared light bulbs to emit heat energy, causing the moisture in the sand sample to quickly evaporate, and then uses a balance to weigh and calculate the moisture content of the sand sample. Its structure mainly consists of a housing, infrared light bulb, microcomputer timing system, switch, and other parts.
(2) Main technical indicators
1. Infrared bulb: 250 watts/220 volts
2. Surface temperature of sand tray: 110 ℃~170 ℃
3. Size of sand tray (bottom diameter x depth): 110 x 27 millimeters
4. Drying time: 6-15 minutes
5. Timer range: 0-99 minutes
6. Power supply: AC220V/10A
