Product Introduction

 STRUCTURE AND PRINCIPLE OF THE ELECTROMAGNETIC PUMP SYSTEM      

An electromagnetic pump is a device that generates pressure gradient via electromagnetic force through the interaction between magnetic field and current in conductive fluid, so as to drive fluid movement. It is mostly used for pumping liquid metal in practical applications, hence also known as liquid metal electromagnetic pump. It is applied to transmit liquid metal and other conductive liquids in closed pipeline systems. Similar to impeller-driven equipment in function, it differs in force generation mode. According to the left-hand and right-hand rules, current passing through a conductor generates an induced magnetic field, which interacts with molten metal to produce induced current. The interaction between induced current and magnetic field generates electromagnetic thrust, which acts as the motive power for molten metal flow. The core feature of the electromagnetic pump is non-contact power generation without any mechanical moving parts.

PRODUCT ADVANTAGES

1. Improve metal recovery rate: The electromagnetic pump system plays a vital auxiliary role in improving metal recovery rate. It shortens the melting cycle through rapid contact and sinking, reduces scum generated during melting, and increases recovery rate. It effectively improves furnace output, optimizes furnace cycle and boosts overall production efficiency after recycling.

2. Convenient for alloy component addition: The electromagnetic pump delivers higher dissolution efficiency for various alloy additives compared with traditional furnace melting.

3. Beneficial to uniform chemical composition: It greatly shortens the dissolution time of various alloy materials and ensures uniform chemical composition of the melt.

4. Reduction of oxidizing slag: Relying on powerful circulation and heat transfer capacity, the electromagnetic pump reduces the surface temperature of the molten pool, controlling the temperature difference between the upper and lower molten pool within 4℃. The high-speed swirling flow in the material well drives solid waste to sink rapidly to the bottom of the molten pool, reducing air contact time and melting time, which greatly inhibits the generation of oxidizing slag.

5. Energy saving: The high-speed and large-flow operation of the electromagnetic pump system accelerates heat conduction and forms a strong sinking vortex, keeping the temperature gradient of the entire molten pool below 4℃. Practical applications prove that it can save at least 10-20% of energy.

6. Environmental protection characteristics: The unique design of the electromagnetic pump system brings outstanding environmental advantages. The closed flow channel greatly reduces heat loss and environmental pollution. It supports efficient external furnace control, allowing various wastes and additives to be added to the aluminum molten pool with the furnace door closed. The melting and feeding of pure and composite alloys can be completed without opening the furnace door, minimizing flue gas emission, maintaining furnace temperature and reducing outside air entering the furnace.

7. Shorten melting time and improve production efficiency: With high-speed and large-capacity flow performance, the electromagnetic pump system effectively improves the dissolution rate of most melting furnaces.

8. Flexible and convenient waste addition: The vortex generated by the electromagnetic pump can melt various types of waste materials.

9. Improve melt temperature uniformity: The fast circulation of the electromagnetic pump system keeps the temperature difference within 4℃ at positions with a height difference of 1 meter in the molten pool.
