Shaoxing industrial pipe machine, stainless steel mechanical specialized factory - three subjects! 

 The Chenzhou three subjects Stainless Steel Co., Ltd. was established in 1993, is dedicated to high-end stainless steel tube complete sets of equipment, high-tech enterprises, the company has a number of independent research and development, patents, and passed the ISO9001 quality management system certification and the company have independent import and export rights. Three subjects because of its superior performance, ultra-high quality, cost-effective, other major vendors in the industry, far ahead, a number of large group companies and strength of state-owned enterprises are the property of our company long-term customers, the product has a high good quality "subjects" well-known overseas, the products are exported to: Malaysia, Taiwan, Vietnam, Bangladesh, Kenya, Russia and other countries with foreign high-end products competing against. With the continuous development of the company in 2009, "Chenzhou Section Stainless Steel Co., Ltd. phase Foshan superior geographical location and mature market environment set up in Foshan Nanhai Luo village of Foshan branch of the" three companies influence further to expand. 
 Three subjects stainless steel decorative tube machine and stainless steel industrial tube series products according to the different needs of the customer groups targeted segments, and then combined with the actual situation of the customers from the two series is subdivided "high-end machines, precision machine, the three grades of" ordinary machines "to meet the different needs of customers. Section "Device specifications vary, from ￠ 6 ￠ 325 tube thickness from 0.2mm ~ 8mm. Molds, polishing machine, embossing machine, leveling machine, annealing equipment and other equipment readily available, providing customers with the perfect service of the whole head to tail, the customer does not have to worry about.

 Cracks and casting speed four characteristics: 1. Casting crack. Development along the grain boundary. Crack formed at higher temperatures, larger alloys and more complex shape castings prone to shrinkage in the volume 2. Heat treatment cracks: Changcheng transgranular crack. Often play in the occurrence of stress and thermal expansion coefficient of the alloy cooling. 

 Thermal disposal, burning or overheating. Sharp corners, or the presence of other metallurgical defects reasons: 1. Casting the structural design is unreasonable. The wall thickness changes is too great. Sand mold (core) give way side. Casting Bureau cooling rate excesses. Charge should be blowing sand, the Ministry of overheating. The pouring temperature is too high. Since the cast 

 Improve its ability to block Java. Appropriate flux residue 4. The cast should be smooth and should have a smooth appearance, out of the type of casting premature. Thermal disposal of hot or burning. The amount of charge-back to use appropriately reduced. Improved gating system design. Note slag 5. Refined before pouring the liquid alloy should put it aside for a certain period of time 

 Sometimes were oil yellow. The appearance of pores, air bubbles can be found by sandblasting, stomatal characteristics of bubble defects: three casting wall pores is generally round or oval. Generally oxide shiny. Internal pores bubbles by X-filling process. To make a judgment to choose reasonable parameters. 4 paint gaseous analysis coatings
