  The structure of tundish quick change nozzle device is simple, which is divided into four parts: base, fixed plate, sector plate and spring pressure flow regulator. The enclosed height is only 110mm. There are two sliding plates in the fan-shaped sliding plate frame. Moving the handle of the fan-shaped sliding plate frame can make the casting hole of one of the sliding plates in the fan-shaped sliding plate frame work. When the other slide brick has moved to the other side of the device, the removed slide brick can be replaced. The device increases the thickness of the slide brick, which can be used as a quick change nozzle device, and the immersion nozzle is installed at the bottom of the slide brick, which can replace the plug rod for protective pouring. The advantages of tundish exchangeable nozzle: 1. Improved casting operator safety 2. Enables longer casting sequences 3. Improved metallurgical quality 4. Flexibility For further details, please feel free t...

  Dry vibration mix is an unshaped refractory material that is vibrated and molded without adding water or liquid binder. Under the action of vibration, the material can form a dense and uniform whole, which can be strengthened by thermosetting bonding agent or ceramic sintering agent when heated. Dry vibration mix is composed of aggregate and powder、binding agent and additive. Dry vibration mix ' s character is : this kind of material is easy to flow under the action of vibration force, and the powder can fill the tiny pores between particle accumulation even under the action of very small vibration force, and obtain a dense body with higher filling density. What's more, it is heated to form a working layer with certain strength. However, there is still a part of unsintered surface showing the original dense accumulation structure. This structure helps to reduce the stress caused by expansion or contraction; Prevent the spread and extension of cracks; Prevent ...
