Description

Technical Field

[0001] The present invention relates to the field of heat treatment technology, and more specifically, to a heat treatment device and method for processing low-carbon steel pipes. Background Art

[0002] Low carbon steel is a carbon steel with a carbon content of less than 0.25%. It is also called soft steel because of its low strength, low hardness and softness. Low carbon steel pipe is a pipe made of this low carbon steel. Low carbon steel includes most ordinary carbon structural steel and some high-quality carbon structural steel. In addition to carbon, its composition generally contains a small amount of silicon, manganese, sulfur, phosphorus and other elements. The strength and hardness of low carbon steel are relatively low, but the plasticity and toughness are good. This makes the low carbon steel pipe have good deformation ability when under pressure and is not prone to brittle fracture. Low carbon steel pipe is easy to accept various processing such as forging, welding and cutting. These processing properties make low carbon steel pipe have greater flexibility and convenience in the manufacturing process. Low carbon steel pipe has good corrosion resistance under certain media and temperature conditions. This allows it to maintain a good service life in some corrosive environments. Low carbon steel pipes are widely used in various occasions that need to withstand low-pressure liquid, gas, and vapor transportation. For example, in the construction field, low carbon steel pipes are often used in water supply and drainage systems, heating systems, etc.; in the machinery field, low carbon steel pipes are often used to manufacture various mechanical parts and structural parts.

[0003] Annealing is an important step in the heat treatment of low carbon steel pipes. Annealing can effectively reduce the hardness of the material and improve the plasticity. When the existing equipment performs annealing on low carbon steel pipes, most of the low carbon steel pipes are fixed in the equipment, resulting in one side of the low carbon steel pipe being closer to the heating element and the other side being farther away from the heating element. This will cause the side of the low carbon steel pipe farther from the heating element to be heated later and at a lower temperature, seriously affecting the annealing effect.

[0004] For example, an ultra-low carbon steel pipe annealing process and device thereof with publication number CN110257600B, the above patent heats the low carbon steel pipe by multiple resistance heating wires, but the multiple resistance heating wires directly heat the lower side of the low carbon steel pipe, while the upper side of the low carbon steel pipe is heated later and at a lower temperature, which results in uneven heating on the upper and lower sides of the low carbon steel pipe, affecting the annealing effect.
