Fine pull seamless steel pipe when using anaerobic bright heat treatment requires not only the mechanical properties of the steel pipe, there are strict technical requirements, while the inner and outer surfaces of the light pipe also have high requirements for fine drawing seamless steel heat treatment if kept in anaerobic or increasing bright simple analysis.

1. Equipment Overview: Usually we use anaerobic treatment equipment continuous mesh belt furnace tunnel doing fine pull seamless steel pipe, one end of such a device to the other end of import for export, in the middle of stainless steel furnace, furnace general width of 40 ~ 50cm, the total length of the device 20 to 25 m can be roughly divided into preheat zone, the high temperature zone, cooling zone, and must comply with the ammonia decomposition gas as the protective device auxiliary equipment;

2, Equipment requirements: fine pull seamless steel pipe during the heat treatment furnace equipment for more stringent requirements, required two-port furnace refractory ceramic excellent line do "throttle", whose role is to prevent air into the furnace , furnace in the middle can not be damaged otherwise air will enter the furnace, each part of the protective gas pressure and pressure pipes to keep them open;

3, Shielding gas: shielding gas liquid ammonia through the ammonia decomposition of hydrogen gas, ammonia decomposition device must work to ensure the protection of the quality of the gas after the device exploded, otherwise fine pull seamless steel pipe during the heat treatment will not be achieved bright;

4, Process: making fine drawing heat treatment process must be developed to guide seamless steel pipe before heat treatment parameters, its provisions during the heat treatment of steel: volume, temperature, belt speed, shielding gas flow, the cooling water temperature and the like.
