Hot-rolled square bar production steps: the secret from material selection to finished product.
Hot-rolled square bars are a common metal product that is widely used in construction, manufacturing, transportation, and other fields. Understanding the production steps of hot-rolled square bars can help you better grasp its features and benefits. Let's walk into the production process of hot-rolled square bars together.
First, the selection of materials. The production of hot-rolled square bars starts with the selection of materials. Generally, steel with high strength, good plasticity and toughness, and corrosion resistance is selected, such as Q235, Q345, etc. At the same time, in order to ensure product quality, the manufacturer will conduct strict inspection of the raw materials entering the factory to ensure that the selected materials meet the requirements.
2. Processing. Cutting: The steel that passes the inspection is cut according to a certain length for subsequent processing and transportation.
Straightening: The cut steel is straightened to remove the bent and deformed parts to make the steel straighter.
Heating: The straightened steel is fed into the heating furnace for heating to bring it to a suitable processing temperature.
Rolling: The heated steel is fed into a rolling mill for rolling, where it is gradually pressed into a square shape.
Cooling: The rolled square bars are fed into the cooling device for cooling treatment to prevent deformation and cracking of the steel.
3. Assemble. The cooled squares need to be assembled for subsequent transport and use. Generally, a special square box is used for assembly, and the assembly quantity and specifications are determined according to the needs of customers. At the same time, in order to facilitate the use of customers, some manufacturers will also provide corresponding accessories, such as connectors, fasteners, etc.
Fourth, quality control.
In the production process, the manufacturer will carry out strict quality control on each batch of hot-rolled square bars to ensure that its quality and performance meet customer requirements. Generally, tensile, impact, hardness and other tests are carried out, and the size and surface quality of the product are strictly inspected to ensure the reliability of the product.
5. Transportation and storage.
After the finished hot-rolled square strip passes the quality inspection, it will be sent to the customer through professional transportation. During storage, care should be taken to avoid direct sunlight and humid environment, so as not to affect the quality and safety of the product.
Summary: The production steps of hot-rolled square bars include material selection, processing, assembly and quality control. Through reasonable material selection and advanced processing technology, as well as a strict quality control system, high-quality hot-rolled square bar products can be produced. Understanding these production steps will help you better select and use hot-rolled square bar products.
