KeyWords: StaticBlade, InvestmentCasting, CAD, CAM1 part structure of 200MW Steam Turbine stator cylinder as shown in Figure l. Material for the ZGCrl1MoV, ZG1Cr13. Leaves generally consists of two parts. (1) leaves the body part: the spatial shape of each cross section in Figure 2, blade plane coordinate system shown in Figure 3. Since the installation of the 10 cross-section angle, leaf axial displacement △,<a href="http://www.stivaliuggitalia.org" target="_blank" class="postlink">ugg milano</a>, different tangential displacement Ay, so leaves the body in space to form three-dimensional shape after assembly into ring cascade, should ensure that a single pitch tolerance ± 0.20mm, The whole loop should be controlled in 41Tim tolerance within the requirements of welding process can only be assured. And control the export of the whole circle area of deviation of the theoretical value within ± 1, can only be assured of the outlet of the separator efficiency stator. Means of implementation, is to control the leaf canopy and leaf relative position of the body. (2) leaf crown components: the design of ISB is better than shroud blade. Its shape is similar to shroud part. Single curved, assembled into a ring. Leaf canopy and leaf to ensure the relative position of the body, will meet the technological requirements of the product. Shows the importance of control of leaf crown deformation. The leaves create the following difficulties: ① mold complex structure, according to the traditional process, require a lot of auxiliary tooling, machining accuracy difficult to guarantee, and a long cycle. * High-Yaron, M. Born in 1969. Engineer, Harbin Turbine Co., Ltd. Daqing Road, Dongli District, Harbin, r 1 (150046) Received date; 1 carp 8 a o8-20 liquid metal pool in the final part of the cavity,<a href="http://www.airjordansshoescheapnike.com" target="_blank" class="postlink">air jordans</a>, all into the set with exhaust residue package area to come to a complete high-quality castings. In actual production, because of the cast made a decisive transformation of the system, the total cross-sectional area within the gate from the original 502mm to 408mm + When the casting process using the data shown in Table 1,<a href="http://www.stivaliuggitalia.org" target="_blank" class="postlink">ugg prezzo</a>, the previous casting defects disappeared. The finished casting from the previous rate of less than 50 to 90 or more, to restore a large amount of economic loss. Practice has proved that: a reasonable pouring water system must have a reasonable number of VI position, take advantage of filling energy. The shape of the gate using the basic control flow of liquid metal base, path, open and reasonable position to judge convergence row overflow system. Be possible to get good castings.
