本文是美国矿山局的研究结果,确定了在以水玻璃和膨润土做粘结剂的橄榄石和锆砂铸型中生产钛和锆铸件的可能性。这一工艺的成功,比传统的捣实石墨型显著地节约能源和劳动力。 钛和锆比重小,比强度大,高、低温性能好,耐腐蚀。因此,钛和锆铸件在化学工业、航空、海运及交通工业上有多种潜在的用途。如泵体、叶轮、容器、发动机连杆等。
This article is the result of a study conducted by the U.S. Bureau of Mines to determine the possibility of producing titanium and zirconium castings in olivine and zircon sand molds that are made from binders such as water glass and bentonite. The success of this process has significantly saved energy and labor over the traditional tamping graphite type. Titanium and zirconium small proportion, than the intensity, high, low temperature performance, corrosion resistance. As a result, titanium and zirconium castings have a variety of potential uses in the chemical, aerospace, marine and transportation industries. Such as the pump body, impeller, container, engine connecting rod and so on.
