slide gate system

This sliding plate mechanism device is a new generation of ladle sliding nozzle device developed by the company. Its biggest feature is that it realizes automatic loading of surface pressure, and drives the sliding mold frame and fixed mold framethrough the stretching of the oil cylinder.Fast pressurization, automatic loading of surface pressure, greatly reduces labor intensity, and makes the force between the slides more uniform, improves the safety performance of the device and the number of continuous slides of the slides, reaching the international advanced level.

Ladle mechanism – Fixed mold frame  

The fixed frame is fixed on the foundation plate, the upper slide gate plate is installed in the fixed frame, and the slide gate plate is fixed by the press brick corner block.

Ladle mechanism – Slide frame

The action of the lower slide gate plate is realized by the sliding frame, which is embedded in the switch frame. The expansion of the cylinder is transmitted to the sliding frame through the connecting rod, thus realizing the closing function of the lower slide gate plate. Like the fixed frame, the lower slide gate plate is also fixed in the sliding frame by the press slide adjusting block.

Ladle mechanism – Switch frame

The switch frame is connected to the fixed frame, the pressure between the slide gate plate board is realized by the spring on both sides of the switch frame, through the rotation of the pneumatic wrench, tighten the four surface pressure bolts (or pull the cylinder to a certain position), the spring press plate is transferred to the spring, so that the spring compression pressure, the pressure is transmitted to the fixed frame through the surface pressure rod boom, so that the upper and lower slide gate plate between enough pressure, Ensure safe use of slide gate plate.

Ladle mechanism – Spring

Surface pressure spring is the most critical part of the whole mechanism. It is made of special heat-resistant alloy, which provides enough strong and stable surface pressure for the normal operation of the slide gate plate. The spring used by the good slide gate plate mechanism is made of imported heat-resistant alloy steel material, and each spring is strictly tested before leaving the factory to ensure the reliability of quality. In order to ensure the normal operation of the spring, the use of compressed air for cooling. Under normal service conditions, spring made of imported heat-resistant alloy steel materials can generally be used 1000-1500 furnace.
