                      硅溶膠鑄造具有尺寸精度高、表面質量好等優點,是一項被廣泛應用的少、無切削的先進工藝,采用硅溶膠鑄造方法可大量儉省機床設備和加工工時,還大幅度節約金屬原材料。硅溶膠鑄造在精密鑄造領域中是一種被廣泛運用的精密鑄造方式,這種精密鑄造方式有效降低了成本,提高了精密鑄造企業的競爭力。澆注成型是硅溶膠鑄造中一個最重要的步驟,那么硅溶膠鑄造有哪些常見的澆注方法呢?
                      Silica sol casting has the advantages of high dimensional accuracy and good surface quality. It is a widely used advanced process with less and no cutting. Using silica sol casting method can not only save a lot of machine tools and processing hours, but also greatly save metal raw materials. Silica sol casting is a widely used precision casting method in the field of precision casting. This precision casting method effectively reduces the cost and improves the competitiveness of precision casting enterprises. Casting is the most important step in silica sol casting. What are the common casting methods of silica sol casting?
                      1. 壓力下結晶,將型殼放在壓力罐內進行澆注,結束后,立即封閉壓力罐,向罐內通入高壓空氣或惰性氣體,使鑄件在壓力下凝固,以增大鑄件的致密度。
                      1. Crystallize under pressure. Place the mold shell in the pressure tank for pouring. After that, immediately close the pressure tank and inject high-pressure air or inert gas into the tank to solidify the casting under pressure, so as to increase the density of the casting.
                      2.真空吸氣澆注,將型殼放在真空澆注箱中,通過型殼中的微小孔隙吸走型腔中的氣體,使液態金屬能更好地充填型腔,復制型腔的形狀,提高鑄件精度,防止氣孔、澆不足的缺陷。這種方法國外較常見。
                      2. Vacuum suction pouring: put the mold shell in the vacuum pouring box and suck the gas in the mold cavity through the small pores in the mold shell, so that the liquid metal can better fill the mold cavity, copy the shape of the mold cavity, improve the casting accuracy and prevent the defects of insufficient pores and pouring. This method is more common abroad.
                      3.定向結晶,一些熔模鑄件如渦輪機葉片、磁鋼等,如果它們的結晶組織是按一定方向排列的柱狀晶,它們的工作性能便可提高很多,所以熔模鑄造定向結晶技術正迅速地得到發展。
                      3. Directional crystallization. Some investment castings, such as turbine blades and magnetic steel, can improve their working performance if their crystalline structure is columnar crystals arranged in a certain direction. Therefore, the directional crystallization technology of investment casting is developing rapidly.
                      4.熱型重力澆注,這是用得最廣泛的一種澆注形式,即型殼從焙燒爐中取出后,在高溫下進行由澆注。.
                      4. Thermal gravity pouring, which is the most widely used pouring form, that is, after the shell is taken out of the roasting furnace, pouring is carried out at high temperature
