AI Technical Summary
The existing vibration molding method for permeable bricks has problems such as unreliable mold fixing, easy loosening, uneven distribution of steel fibers, low production efficiency, unstable product quality, and the vibration parameters not being matched with the castable, resulting in molten steel leakage and uneven molding.
The mold is fixed by magnetic attraction using relay control, frequency converter control, or PLC control. Combined with pressure sensor and time relay or frequency converter, the current frequency and vibration force of the vibration motor are controlled to achieve reliable fixation of the mold and vibration system and automatic vibration force adjustment.
It improves the fixation reliability of the mold and vibration system, reduces the uneven distribution of steel fibers, improves production efficiency and product quality stability, achieves matching of the weight of the castable with the vibration force, and avoids segregation and unevenness.

Abstract
Claims
1. A ladle gas permeable plug forming system controlled by a relay, characterized in that: The molding system comprises three parts: a permeable core or seat brick mold, a vibration system, and a control system. The base plate of the permeable core or seat brick mold is made of steel, has paramagnetic properties, and is 10mm-30mm thick. The vibration system includes one or more vibration motors, a symmetrical steel structure working platform, multiple damping springs of the same type, and one or more electromagnets. When the electromagnets are energized, they are attracted and fixed to the mold; when the electromagnets are de-energized, they have no active force on the mold, and the mold can be moved away. The core components of the control system are a multi-position selector switch, multiple cyclic time relays, and a contactor. Three-phase AC power enters the vibration motor after passing through the working terminal of the contactor. Each line of the multi-position selector switch is connected to a cyclic time relay, and the output terminals of all cyclic time relays are connected to the input terminals of the contactor control system.
2. The forming system of claim 1, wherein: If there are multiple vibration motors, they must be of the same model and adjusted to the same excitation force. The steel frame with the vibration motors and electromagnets installed is placed on the damping springs.
3. The forming system of claim 1, wherein: The sum of the excitation forces of the vibrating motors is 1.3 to 1.5 times the weight of the steel structure workbench, the weight of all the vibrating motors, the weight of all the electromagnets, the weight of all the molds, and the weight of the molds filled with refractory castable. The magnetic force of the electromagnets acting on the molds is more than 1.1 times the excitation force.
4. The forming system of claim 1 wherein: The multi-position changeover switch has 4-8 circuit positions, one of which is a normally closed circuit.
