Advantages of dry vibrating material in tundish

 Tundish dry vibrating materials are mainly used for tundish linings, and are the third generation of high-tech products after insulation panels and tundish coatings. Magnesium materials have good resistance to corrosion by high-speed iron and high-alkaline slag, and have the characteristics of long service life and no pollution to molten steel.

The dry vibrating mix has good construction performance, high low-temperature demolding strength and high medium and high temperature strength, which can meet the requirements of customers for low temperature baking and medium and high temperature use of dry material working lining in tundish.

Advantages of dry material construction:

(1) The construction process is convenient and fast

(2) Reduced labor intensity

(3) Improved construction environment

(4) No dust, no irritating gas, no pollution to the environment

The construction of dry vibrating material

 The construction of dry-type vibrating material is divided into direct vibration and indirect vibration, and the tundish is used as an example to illustrate. The direct vibration method is to use a flat-plate vibrator to vibrate while laying the material, constructing layer by layer. After the package bottom construction is completed, put the side wall mold into the package wall. After the construction of each layer, the surface layer should be harrowed and new dry vibrating materials should be added to prevent delamination. The indirect vibration method is to install the vibrator on the mold, and the vibration force is transferred to the dry material through the template to obtain a dense construction body. The installation position and quantity of the vibrator shall be subject to the compactness of the lining material.?

First, clean the surface of the permanent lining, install the impact plate and the seat brick, ram the surrounding with dry material to compact, then pour the dry material into the bottom of the bag, pat it flat with a spade, and ensure the thickness of the bottom of the bag (to leave out the vibration compression)

Secondly, install the tire mold, the distance between the tire mold and the surrounding permanent lining is the same, so that it reaches the required thickness of the working lining.

Thirdly, pour the dry virbrating mix into the upper edge of the tire mold, and activate the vibrator to vibrate for 4-6 minutes. Then add the material and vibrate until the dry material reaches the edge of the package; the fourth cleaning site, ignite the baking burner on the tire mold for low-fire baking, the baking temperature is 180-270℃, and the time is about 2h, so that the dry material is hardened. Obtain a certain strength, and then carry out air cooling to make the temperature of the tire mold drop below 100 ℃ and demold; Check the condition of the lining body, and repair it in time if there is a defect. Generally speaking, the construction of dry vibrating materials uses both methods in order to achieve the maximum density of the lining and increase its service life.
