Octagonal tube sizes, galvanized octagonal tube factory, octagonal tube manufacturer

The octagonal tube features high toughness, and can mainly demonstrate excellent plastic deformation compressive strength during use, making it less prone to damage after the product is formed.

What is an octagonal tube? Very simple, it's aluminum extrusion produced by cold drawing high-quality stainless steel sheets. Cold-drawn aluminum extrusions can be divided into two types: hot-rolled cold-drawn aluminum extrusions and cold-drawn cold-drawn aluminum extrusions. The significant difference between them lies in the processing technology.

The octagonal steel pipe has significant overlap in application scale and cold-rolled steel in terms of use, sharing many similarities. Besides its primary industrial applications, cold-rolled steel can also be used in the industry to produce bullet shells for firearms and other mechanical weapons.

According to statistics, the use of cold drawn steel in industrial production effectively ensures the function and efficacy of products, playing a crucial role in enhancing the overall quality of machinery and equipment. It is evident that the application of cold drawn steel is extremely widespread, which has prompted further optimization of the categorization of cold drawn steel products.

Octagonal tubes may exhibit some wavy patterns during quenching, primarily centered waves and edge waves, with a small amount of double-rib waves. Such defects are generally related to factors such as the quality of finished product inspection, the level of damage to the furnace bottom roller of the generator set, and welding stresses during heating and cooling. We can adopt the following countermeasures to prevent them:

(1) Adjust based on increasing the cardiac output of the industrial cooling fan, and regulate according to the enhanced power of the fast industrial cooling fan.

(During the processing of special-shaped steel, adjusting the height and model and manipulating the furnace atmosphere can reduce the time for rolling mill bonding, thereby lowering the overall damage to the carbon sleeve roller. If there is still overall damage and edge waves to the carbon sleeve roller at this point, it is due to the carbon sleeve roller being in service beyond its expiration date.)

(3) To eliminate edge waves on both sides and reduce the N2 intake at the edge of the octagonal steel pipe, increase the N2 intake at the two ribs, adjust the proportion of the controlled cooling plate from the original 2-5-9-5-2 to 1-6-9-6-1.

(4) Under normal conditions, the supporting force of the Wuxi八角 steel pipe in the continuous reheat furnace is calculated and set based on the specifications and models of the Wuxi八角 steel pipe, with the standard being to ensure the smooth operation of the Wuxi八角 steel pipe. Insufficient supporting force affects the working ability of the correction device roller, and cannot ensure that the Wuxi八角 steel pipe operates on a straight path in the furnace chamber, causing the pipe to deviate in direction within the furnace. In severe cases, it can lead to edge scraping. When the finished product inspection reveals a waviness of 1.5%, the internal tension of the furnace should be reduced as much as possible.
