Casting weight and size ranges are wide bucket wheel guard equipment products, only a few grams of the lightest and heaviest up to 400 tons, the thinnest wall thickness of only 0.5 mm, the thickness can be more than 1 meter in length by a few mm to ten meters, can meet the requirements of different industrial sectors. Casting quality has a great impact on the performance of mechanical products. For example, wear resistance and dimensional stability of the casting machine, a direct impact on the accuracy of the machine to maintain life; all kinds of pump impeller, housing and hydraulic cavity size, accuracy and surface roughness profile, directly affect the pump and efficiency of the hydraulic system, the development of energy consumption and cavitation etc; intensity combustion engine block, cylinder head, cylinder, piston rings, exhaust pipes and other castings and resistance to spalling of protective equipment bucket wheel directly affects engine working life. Casting defects: cold resisting grain Other names: Splice (butt), waterlines. Features: low temperature metal flow mutual butt fusion but the emergence of a gap, irregular linear dock wheel guard Hom equipment, there are two non-penetrating and penetrating, there is a trend developing in the role of external forces . Reason: a molten metal pouring temperature is low or the mold temperature is low. 2, alloy composition does not meet the standards, poor mobility. 3, sub-unit filled with liquid metal, fusion is bad. 4, gate unreasonable process is too long. 5, filling speed is low or poor venting. 6, lower than the pressure. Bucket wheel guard equipment supply, Chen Hua machinery (certified), wheel guard Hom equipment provided by China Machinery Equipment Co., Ltd. Qingdao Chen. Qingdao Hua Chen Machinery Co., Ltd. (www.qdchenhua.com) is Qingdao, a leader in CNC machine tools over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
