钢纤维浇注料
钢纤维增强浇注料衬体的运用效果,与其制造技术有密切关系,因此在制备技术中有必要留意如下疑问:
The application effect of steel fiber reinforced castable lining is closely related to its manufacturing technology, so it is necessary to pay attention to the following questions in the preparation technology:
钢纤维浇注料
Steel Fiber Castable
1、有必要依据运用条件挑选适当商标的高温合金钢纤维和其加入量(通常在1%-3%),加入量过多有反效果;
1. It is necessary to select appropriate trademarks of high temperature alloy steel fibers and their addition amount (usually 1%-3%) according to the application conditions. Excessive addition will have a negative effect.
2、混合拌和时,最佳先将干浇注料加水拌和均匀,然后再加入钢纤维拌和均匀,这样不只使浇注料自身易混合均匀,并且也不会因拌和时刻过长、因拌和叶的重复搅动而使钢纤维弯曲变形;
2. When mixing, the best way is to mix the dry castable with water and then with steel fibers, which bianpinqi.37ix.com.cndiaoke.37ix.com.cnshidiaodx.37ix.com.cnshidiaofx.37ix.com.cnnot only makes the feiqicc.37ix.com.cnfeiqicl.37ix.com.cncastable itself easy to mix evenly, but also does not bend the steel fibers because of the long mixing time and the repeated stirring of the mixing leaves.
3、振荡成型时,通常最佳选用附着式振荡器,从模型外部施加振荡力,以使钢纤维能无取向均匀分布,不宜选用刺进式振荡施工,否则会损坏钢纤维的均匀分布。而制造预制件(块)时,也可选用平面振荡台施工。
3. Attached oscillator is usually the best choice in shaping, and the oscillating force is applied from the outside of the model to make the steel fibers distribute uniformly without orientation. It is not suitable to use piercing oscillation construction, otherwise the uniform distribution of steel fibers will be damaged. When making prefabricated parts (blocks), plane oscillator can also be used for construction.
钢纤维增强浇注料的主要效果在于提高在应力效果下的应变功能,然后提高浇注料衬体的耐性、力学强度和抗热震性
The main effect of steel fiber reinforced castable is to improve the strain function under stress effect, and then to improve the resistance, mechanical strength and thermal shock resistance of castable lining.
