Automatic batching system after cupola furnace (iron, coke, stone):
Uses and effects:
The system can realize microcomputer automatic iron distribution, automatic scorch distribution, automatic feeding process automation, automatic positioning control of batching crane, automatic air volume and pressure detection, iron temperature detection, cooling water monitoring, centralized monitoring and optimization management of the upper computer. It can "fix coke with iron" and distribute coke stone to realize safe and automatic weighing of new iron, furnace material, scrap steel, coke and stone, with obvious use effect. The quality of molten iron is stable (the temperature is increased by 10-20 ℃), the fluctuation rate of carbon content is low, the rate of genuine products is increased (scrap is decreased by 2%-5%), energy consumption is saved and manpower is saved.

System introduction:
The system consists of a modular combination of multiple subsystems, each subsystem is independent and can run online, so that control, monitoring, management integration, at the same time, due to the strict requirements of industrial control and the poor environment of the foundry workshop, the system is fully redundant, in one of the subsystem problems, immediately switch to manual state without affecting the operation of the whole system.

Performance description:
It is suitable for weighing and distributing metal furnace charge in cupola furnace, realizing the weighing of new iron, returning furnace charge and scrap steel, with obvious use effect. To ensure the temperature of molten iron, the temperature of molten iron is generally increased, the fluctuation rate of carbon content is reduced, the scrap rate is decreased, the consumption of furnace charge and energy is significantly reduced, labor force is greatly saved, and production cost is reduced.
The iron distribution system adopts advanced high-integration module as the control core, mainly used for the weighing of new iron, recycling materials, scrap steel and other iron materials, with high batching accuracy, stable and reliable data transmission, strong anti-interference ability and so on. The main performance is as follows:
1. High batching accuracy and small error.
2. The batching time is short, and the average time of mixing once is not> 20S.
3. The system is intuitive and simple, simple to operate, that is, to learn.
4. This system has the function of upgrading, and can be equipped with a microcomputer iron meter to realize the function of automatic iron distribution.

System composition principle:
The equipment is mainly composed of rectifier control cabinet, electromagnetic chuck, cable reel, wireless hook sensor, digital display instrument, cable connector, etc.
The wireless steel shell hook scale transmits the signal to the large display screen, and the operator can control the magnetic force of the electromagnetic chuck to carry out batching according to the number displayed on the large display screen until the fixed value is reached (within the allowable range).

System workflow:
Make preparations before starting the furnace-> the operator remotely controls the suction cup to suck the material-> lifting the crane-> batching according to the weight displayed by the wireless hook sensor-> run the iron material sucked by the suction cup to the cupola hopper-> discharge the material.
