How To Deal With The Decarburization Problem On The Surface Of The Ck45 Honed Tube?

- Jul 24, 2019-

Square steel is a bar and is solid. In the production process, the heat treatment process is carried out, so that a bright continuous heat treatment furnace is used, so that the intermediate heat treatment and the heat treatment of the finished product can be performed, so that the surface of the square steel becomes bright and the tradition can be omitted. Pickling this process.

 

There are generally three types of bright continuous heat treatment furnaces, such as a roller-type bright heat treatment furnace, a mesh belt type bright heat treatment furnace, and a muffle tube type bright heat treatment furnace.

 

Decarburization occurs on the surface of the Ck45 honed tube, mainly related to oxidizing gases such as oxygen, water vapor and carbon dioxide, and is also related to the heat treatment process. Therefore, these two aspects must be solved to avoid decarburization on the surface of the honing pipe. Therefore, in the heat treatment process, the steel wire should be kept out of contact with these oxidizing gases.

 

In addition, if there is residue on the steel wire, some oxidizing gas will be generated after heating in the furnace, which causes this phenomenon. Therefore, we must control the atmosphere in the furnace to avoid this phenomenon.
