1. Smaller outer diameter.
2.High accuracy can be made in small batches
3. Cold drawn products have high precision and good surface quality.
4. The horizontal area of steel pipe is more complicated.
5. The steel pipe has better performance, and the metal is denser.
Hot-rolled cylinder tubes use continuous casting round tube slabs or preliminary rolled slabs as raw materials, are heated by a step-type heating furnace, are descaled by high-pressure water, and enter the rough rolling mill. Computer controlled rolling is implemented. After the final rolling, it is coiled by laminar cooling and coiler to become a straight hair coil. Straight hair curls tend to have tongue and fish-tail shapes, with poor thickness and width accuracy. Waves, folds, and towers are often present at the edges. Its coil weight is heavy and the inner diameter of the steel coil is 760mm. Straighten the coils after cutting, trimming, trimming, and multiple straightening, leveling, and other finishing lines, and then cut or rewind the coils to become: Cut tape and other products. If the hot-rolled finishing coil is pickled to remove scale and oil, it will become a hot-rolled pickled coil.
The use of stainless steel for the cylinder tube has the characteristics of light product design and long service life.
Because stainless steel has high strength and corrosion resistance, compared to aluminum, iron and other materials, because of its high strength and non-magnetic, it can be designed to be thinner than aluminum and iron materials, which can reduce the size and weight of the product. . Is the first choice for portable automation equipment.
The inner and outer roughness of the stainless steel cylinder tube can reach Ra0.2-0.4, and the inner and outer tolerance zone can reach 0.03mm; the specifications range from Φ3--Φ60mm, and the wall thickness is 0.2-1mm.
