Smooth high-pressure resistant pipe fitting processing technology for spinning melt

Abstract

The invention discloses a smooth high-pressure resistant pipe fitting processing technology for spinning melt, and relates to the technical field of pipe fitting processing. The technology comprises the following steps of SS01, pipe casting, specifically, a pipe fitting comprises an outer pipe layer, an interlayer, an inner pipe layer and a group of edge sealing layers, the outer pipe layer, the inner pipe layer and the edge sealing layers are made of alumina ceramics and the interlayer is made of C-276 alloy steel. The high-pressure resistant, wear-resistant and smooth pipe body is produced through multi-layer composite use of the materials, so that when the spinning melt process is used for producing synthetic fibers, the production quality of the synthetic fibers is higher, the production cost is reduced, and a plurality of slots are formed in the circumferential side face of the C-276 alloy steel fixed between the double-layer alumina ceramics, so that the hardness of the C-276 alloy steel is high, the stability of the C-276 alloy steel is better, the C-276 alloy steel is matched with the characteristic of higher compression resistance of the alumina ceramics, the effect of thepipe body in application is better, the hardness of the alumina ceramics is higher, the smoothness after polishing is better, and the pipe body is not likely to wear.

Description

technical field [0001] The invention belongs to the technical field of pipe fittings processing, in particular to a processing technology for smooth high-pressure resistant pipe fittings for spinning melt. Background technique [0002] Spinning melt is one of the main forming methods of chemical fibers, referred to as melt spinning. The main varieties of synthetic fibers such as polyester, nylon and polypropylene are produced by melt spinning. The main features of melt spinning are high winding speed, no need for solvents and precipitants, simple equipment, and short process flow. Fiber-forming polymers that melt below their decomposition temperature and can be melted to form thermally stable melts can be formed by this method. [0003] In the process of spinning melt processing, smooth and pressure-resistant pipes are often used for processing synthetic fibers. The smoothness of the pipe and the pressure resistance of the pipe play a great auxiliary role in the process of...
