Embodiment

[0046] A production process of stainless steel seamless steel pipes for ships, comprising the following steps:

[0047] S1: Tube billet preparation: round tube billets are made through ironmaking, steelmaking, ingot casting, blooming, rolling round steel and other processes;

[0048] S2: Tube billet inspection, fixed cutting: inspect the round steel billet, confirm that the tube billet has no obvious trauma or surface depression and other raw material problems, and then perform fixed cutting treatment;

[0049] S3: tube billet heating, hot-rolled piercing: the cut tube material is sent to the furnace for heating through the conveyor belt, and the heated tube material is hot-rolled and pierced through pressure piercing machine and other equipment;

[0050] S4: pickling: immerse the pipe material in an acid solution to produce a chemical reaction, and then clean it with pressure water;

[0051] S5: Surface polishing: send the pickled pipe material into the equipment for surface...

Abstract

The production technology comprises a base, a first side supporting plate is fixedly mounted on the left side of the upper end of the base, a movable groove is formed in the upper portion of the right end of the first side supporting plate, and a grinding mechanism is slidably connected into the movable groove; a second side supporting plate is fixedly installed on the right side of the upper end of the base, the left end of the driving mechanism is connected with the driving mechanism and a rotating mechanism in a penetrating mode, the driving mechanism and the rotating mechanism are movably installed on the second side supporting plate through bearings, the driving mechanism and the rotating mechanism are in transmission connection, and a clamping mechanism is arranged at the left end of the rotating mechanism. According to the production technology of the stainless steel seamless steel pipe for the ship, through multiple times of surface polishing treatment and deoiling and degreasing, the pipe is good in surface quality, free of burrs and accurate in size, the surface of the pipe is polished through multiple times of production equipment of the stainless steel seamless steel pipe for the ship, the labor intensity is low, the grinding efficiency is high, stress is uniform, and the grinding quality is high.

Description

technical field [0001] The invention relates to the technical field of production of stainless steel seamless steel pipes, in particular to a production process and production equipment for stainless steel seamless steel pipes for ships. Background technique [0002] Seamless steel pipes are steel pipes made of a single piece of metal with no seams on the surface. According to the production method, seamless pipes are divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, and jacked pipes; Shape, seamless steel tubes are divided into two types: round and special-shaped, and special-shaped tubes have square, oval, triangular, hexagonal, melon-shaped, star-shaped, and finned tubes in various complex shapes; the maximum diameter of seamless steel tubes is 650mm, and the minimum The diameter is 0.3mm; depending on the application, there are thick-walled pipes and thin-walled pipes; seamless steel pipes are mainly used as petroleum geological drilling...
