Tungsten Carbide Floating Plug
The tunsten carbide floating plug is mainly used for drawing copper pipes, and it is used in conjunction with the drawing die (also known as the outer die, the drawing die). The moving core is not fixed in the copper tube, and it is through friction with the copper tube. The force and the reaction force when the copper tube deforms reach a balanced state, so it is called a moving core, and a fixed core is opposite to it. The length of the copper tube drawn with the moving core head can reach more than one kilometer. The moving core head controls the inner diameter of the copper tube, and the tube drawing die controls the outer diameter of the copper tube. The moving core is one large and one small. The big head is used for guiding, the small head is used to control the size, and the two ends should be smoothly transitioned; now there are small heads at both ends and the big head in the middle, which is called double-headed swimming core head, which can be used as two swimming core heads. use. Tungsten steel swimming cores have very strict requirements on materials, and they must maintain good strength while ensuring high hardness. In particular, blisters and cracks are not allowed. The alloy surface must be polished to a mirror finish.
Zhuzhou Max Precision Co., Ltd. has developed outstanding grades MA20 (HRA≥91.50 TRS≥3000) and MA50 (HRA≥92.00 TRS≥2800) for the use characteristics of the moving core head to select drawing according to different material diameters, and the market feedback drawing The output is twice that of ordinary materials YG6 and YG6X, and the quality is stable! Max carbide uses high-quality primary fine-grained raw materials, granulated through a spray tower, and then eliminated compression defects through CIP, and then through HIP (pressure sintering) to ensure product quality.
