Thick due to the production of castings is easy to produce more shrinkage, shrinkage and other defects. Core shape by fight-type group, the use of feeding gating system to take cold water and slowly pouring the full complement other technological measures to ensure the quality of the casting bed. Key words: solid casting; gate feeding; fight type group core; casting process CLC: TG24 Document code: B0 Huangshi Textile Machinery foreword for a forging machine y-produced Received Date: 2o0l-l0- 2l Author: Guo, and (1965 a), male, Han nationality, Hubei Luotian County,<a href="http://www.uggsstivali.org" target="_blank" class="postlink">stivali ugg</a>, Bachelor of Engineering, senior engineer, mainly in iron and copper alloy production and technical work force, in professional journals published over 20 papers. Two bed, is forging an important part of the machine, the Department of thick large section castings. Bed quality was 4400kg and 5000kg,<a href="http://www.airjordansshoescheapnike.com" target="_blank" class="postlink">air jordans</a>, casting material is HT300. Casting structure is relatively simple, but the size and wall thickness greater height, does not allow holes,<a href="http://www.uggsstivali.org" target="_blank" class="postlink">ugg italia</a>, slag, shrinkage and other casting defects. Inoculant treatment of barium strontium that is able to meet customer requirements, particularly when the production of Heavy iron ball, the use of antimony heavy rare earth nodulizer better. ��2) The long-term strontium barium silicon inoculant to solve the Ministry of Heavy Section Ductile graphite core distortion is effective. The use of antimony low rare earth agent,<a href="http://www.monclerjackens.net" target="_blank" class="postlink">moncler günstig</a>, the use of barium strontium silicon inoculant only when long-term good results, when using antimony nodulizer heavy rare earth, the use of silicon and ferrosilicon barium strontium can be made good as inoculant effect, but is better conceived of silicon barium strontium. (3) to address the Ministry of Heavy Section Ductile graphite core distortion, should control the chemical composition, selected a lower c, si, and the amount of carbon equivalent and low sulfur content in iron melt. (4) sand with trees and aims to produce large cross-section ductile iron should be taken to ensure the sand mold (core) compactness, in the place cold iron Heavy parts, control the frequency of use of cold iron, pouring hot air blowing to the cavity, increasing area of the eye area and gas feed system, ensure that process measures such as liquid iron supplement.
