Customer in Serbia ordered 100 tons refractory castable
In December. 100 tons refractory castable are packed for delivering to customer in Serbia. High quality nice price refractory castable materials in Topower Refractory.
The molding method of fire -resistant castable is: vibration molding, pounding molding, shaping molding, grouting molding, and heat pressure molding. Under normal circumstances, the proportion of vibration molding refractory castable materials is large, and there are not many sinking molding and thermal pressure molding. The vibration molding is between the mold and the castable material. Use the vibration rod vibration to make the castable particles have liquidity to fill all parts of the mold. At the same time, the small particles can also be filled in the gap of the large particles to make the refractory castable more more refractory castable. Conflict.
The advantages of vibration molding are small labor intensity and low cost. Suitable for large or plate -shaped bodies. The disadvantage is that the rigidity of the steel plate and spring of the mold is different, especially the large plate -shaped experience is unevenly dense. There is also the unevenness of the denseness when the construction is intermittent. In order to improve the density of molding, you can also use pressure vibration, while vibrating while pressing.
The pounding forming is a pounding of the hammer, so that the pounding method can obtain a certain degree of densely forming method. Pin the hammer with strength or electric driver, you can also use manually. The pounding of the ingredients is to add the model in turn, and the tincture of the layer in turn. Before each feeding, the surface of the last tiny layer should be loosened to avoid separation or cracking between the layers. But this method is too labor -intensity and noise.
The shape of the plastic material is the molding method that plasticized materials are placed in the model by squeezing the mud, and then the size required by the mud strip is cut into rough at the exit. Burned through drying. In order to increase the density of raw blanks, the use of vacuum equipment is used to facilitate mud exhaust.
The grouting molding is to inject the suspension of the powder into the gypsum mold. After the gypsum mold absorbs the moisture, it is solidified to get the body. Then pour out part of the unsaturping mud in the center. There are also ways of grouting for molding, stress grouting, centrifugal grouting, and vacuum grouting. Pressure grouting is to shorten the slurry time with gravity or compressing air, and reduce the water in the blank pulp after the release. The centrifugal slurry is to spin the mold with the slurry. The centrifugal slurry will close the material to the mold wall. This method is uniformly thick, not easy to deform, and less water. Vacuum grouting is vacuum to draw the model outside. This method is fast -absorbing water and can improve the quality of the body.
The heat pressure molding is very small in the application of fire -resistant castable materials, mainly for the ceramic industry.
In short, no matter what kind of molding method, it is dependent on different products of refractory castable.
