Construction of dry vibrating material

The construction of dry vibrating material is divided into two types: direct vibration and indirect vibration. The direct vibration method is the construction of vibration on one side and side by side. After the completion of the bottom construction, the side formwork is constructed. After each construction, surface layer should be raked and new dry material added to prevent stratification. In the indirect vibration method, the vibrator is mounted on the formwork, and its vibration force is transmitted to the dry material through the formwork to obtain the compact construction body. The installation position and quantity of the vibrator shall be in accordance with the compactness of the lining material. Firstly, clean the lining surface, install impact plate and seat brick, compact with dry material around, then pour dry material into the bottom of the package, flatten with spade beat and ensure the thickness of the bottom of the package (to retain the compression of vibration); secondly, install the tire mold, the distance between the mold and the surrounding lining is the same, so as to achieve the thickness required by the working lining; thirdly, general. Pour the dry material into the upper edge of the mold, start the vibrator to vibrate for 4-6 minutes, and then vibrate until the dry material reaches the edge of the mold; Fourth clean-up site, ignite the baking nozzle on the mold for small fire baking, baking temperature 180-270 C, time about 2 hours, so that the dry material hardening and obtain a certain strength, then air-cooled, so that the tire. Mold temperature drop to below 100 c release; check the lining condition and repair in time when defective. Generally speaking, the construction of dry vibrating materials, are two methods used together to achieve the density of the lining, improve its service life.
