Problems solved by technology

The current problem with this method of sealing tubes is that the sealed quartz glass tubes are disposable, and the tubes must be broken after the sample is annealed, resulting in high costs, and the sealing of the tubes requires a special vacuum system and Quartz or glass tube heating and softening equipment, it is also very inconvenient to seal the tube

Abstract

The invention discloses a high-speed steel circulating water bath annealing pipe. The high-speed steel circulating water bath annealing pipe is characterized in that the high-speed steel circulating water bath annealing pipe comprises an annealing pipe body; a combustion chamber and a water bath trough are sequentially arranged on the annealing pipe body in the high-speed steel movement direction; a water inlet pipe and a water outlet pipe are arranged at the two ends of the water bath trough correspondingly in the annealing pipe body direction; water in the water bath trough spills over the annealing pipe body; the water inlet pipe and the water outlet pipe communicate through a circulating pump; a plurality of gas holes are formed in the two side faces, in the horizontal direction, of a pipe section, arranged in the combustion chamber, of the annealing pipe body; an igniter is arranged in the combustion chamber; a fresh air inlet is formed in the lower end face of the combustion chamber; a smoke outlet is formed in the upper end face of the combustion chamber; a flexible sealing block is arranged at the high-speed steel outlet end of the annealing pipe body; and a hydrogen inlet is formed in position, at one side of the water bath trough, of the annealing pipe body.

Description

technical field [0001] The invention relates to the field of metal annealing, in particular to an annealing tube for high-speed steel. Background technique [0002] Annealing is a metal heat treatment process, which refers to slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate speed. The purpose is to reduce hardness, improve machinability; eliminate residual stress, stabilize size, reduce deformation and crack tendency; refine grain, adjust structure, and eliminate structure defects. To be precise, annealing is a heat treatment process for materials, including metal materials and non-metal materials. Moreover, the purpose of annealing new materials is similar to that of traditional metal annealing. [0003] Annealing is a very commonly used experimental method for sample preparation and sample processing in the field of scientific research and production. For some samples that can be annealed in an air...
