Description

Hot rolling

(Extruded seamless steel pipe) : round tube blank → heating → perforation → three-roll skew rolling, continuous rolling or extrusion → Stripping → sizing (or reducing) → cooling → straightening → hydraulic test (or detection) → marking → storage

The raw material of rolling seamless tube is round tube blank, and the round tube embryo is cut by the cutting machine and the billet with the growth degree of about 1 meter, and is sent to the furnace by conveyor belt for heating. The billet is heated in the furnace at a temperature of about 1200 ° C. The fuel is hydrogen or acetylene. The temperature control in the furnace is the key problem. After the round tube billet is released, it must be perforated by the pressure piercing machine. Generally, the most common piercing machine is the conical roll piercing machine, which has high production efficiency, good product quality, large perforating and expanding diameter, and can wear a variety of steel. After the perforation, the round tube blank is successively rolled by three roller skew, continuous rolling or extrusion. After extrusion, the tube should be removed for sizing. The sizing machine rotates into the steel embryo at high speed through the conical drill to punch holes and form the steel pipe. The inner diameter of the steel pipe is determined by the outer diameter length of the caliper drill bit. After the steel pipe is calibrated, it enters the cooling tower and is cooled by water spray. After the steel pipe is cooled, it will be straightened. After the steel pipe is straightened, it is sent to the metal inspection machine (or hydraulic test) for internal inspection. If there are cracks, bubbles and other problems inside the steel pipe, it will be detected. After the steel pipe inspection, it is also strictly selected by hand. After the steel pipe quality inspection, paint the number, specification, production batch number, etc. And hoisted by crane into the warehouse.

Uses of packaging in the steel industry

Protective function

- Prevent steel products from physical damage, such as collision, scratching and extrusion, during transport, storage and handling to avoid affecting the quality and appearance of the products.

- Insulate from external environmental factors, such as humid air, rain, dust, etc., to reduce the risk of rust and corrosion of steel and ensure the performance and service life of the products.

Wooden box packaging

- Use: Mainly used to protect some irregular shape, easy to damage or high requirements for packaging of steel products, such as precision parts and components.

- Specific description: the wooden box is made of thick wooden boards, and cushioning materials, such as foam, air cushion, etc., may be added inside to reduce the impact of vibration and collision on the product.

Anti-rust paper packaging

- Purpose: To prevent rust and corrosion of steel products, especially suitable for storage or transportation in a humid environment.

- Specific description: anti-rust paper usually contains rust inhibitors, can be in contact with the metal surface to form a protective film, blocking the erosion of moisture and oxygen.

Plastic film packaging

- Purpose: To provide basic protection against dust and moisture, commonly used for small steel products.

- Specific description: plastic film has a certain degree of flexibility and sealing, can be tightly wrapped in the product surface, effectively isolate the external environment.

Pallet packaging

- Purpose: To facilitate the stacking and handling of steel products, and improve logistics efficiency.

- Specific description: The pallet is usually made of wood or plastic, the steel products are placed on the pallet, and then the forklift and other tools can be used for handling and loading and unloading.

Factory container packing

- Purpose: It is used for mass transportation of iron and steel products, to protect the products and improve the utilization rate of transportation space.

- Specific description: Containers have a strong structure and good sealing, and can adapt to long-distance transportation and the conversion of multiple modes of transportation.

Anti-rust oil coating packaging

- Purpose: To form a layer of antirust oil film on the surface of steel and enhance the antirust ability.

- Specific description: evenly cover the steel surface with anti-rust oil by brushing or soaking to form a durable protective layer.

Metal Corner Protection Packaging

- Purpose: To protect the corners and edges of steel products from damage during handling and transportation.

- Specific description: Metal corner guards are usually installed on the corners of products, using welding, bolting and other methods to increase the strength and impact resistance of the corners.
