First, the basic overview:

1. Type: sand core dry furnace Alias: mold drying oven

2, model: continuous rolling type (non-standard custom)

3, studio size: L × M × H (mm)

4, working temperature: 150-200 (°C) furnace maximum temperature: 350 (°C)

5, dimensions: - (mm)

Second, the main purpose of the equipment: sand core dry furnace is mainly used for surface drying after large-scale sand core dip coating, using electric heating or natural gas as fuel. The dry furnace of the watch adopts the principle of forced hot air convection heat transfer. The electric heater or the natural gas furnace concentrates combustion and heat exchange, and the hot air is circulated through a special circulation fan, and the air jets are arranged in a matrix arrangement on the air supply device. The sides and top of the furnace are directly blown to the surface of the workpiece. The circulating hot air has sufficient speed, the hot air in the furnace is turbulent, the sand core is heated evenly, and the hot air and the sand core are exchanged and returned to the heat exchanger via the return air device for reheating. , complete a loop.

Third, the basic structure of the equipment: its basic structure should include: furnace body (including furnace lining), raceway, raceway transmission, heating, cooling, sealing, temperature control and recording system.

Fourth, the basic characteristics of the equipment: The dry furnace of this table is a large non-standard product, our unit is specially designed and manufactured according to the process requirements and production conditions. As far as possible, the equipment is scientific, technologically advanced, safe, and stable.

——The man-machine interface is connected with the PLC. The operating status of each system is recognized by the PLC and the temperature control instrument data is collected and displayed and recorded on the human-machine interface device.

——Human-machine interface has fault detection function. It can detect natural gas supply over-voltage, under-voltage fault, natural gas combustion system operation fault, electric heating through PLC. The human-machine interface has fault detection function. It can detect natural gas supply over and under voltage through PLC. Failure, operation failure of natural gas combustion system, failure of electric heating system, failure of circulating fan, operation failure of conveying system, over temperature and under temperature failure in furnace. The man-machine interface has various fault display functions.

——The human-machine interface has a recording function to record and save equipment failure, heating temperature, drying time, productivity, etc., for query and production management. The man-machine interface can be printed by the computer through the panel output interface.
