什么是槽钢？槽钢属建造用和机械用碳素结构钢，是复杂断面的型钢钢材，其断面形状为凹槽形。槽钢主要用于建筑结构、幕墙工程、机械设备和车辆制造等。在使用中要求其具有较好的焊接、铆接性能及综合机械性能。 产槽钢的原料钢坯为含碳量不超过0.25%的碳结钢或低合金钢钢坯。成品槽钢经热加工成形、正火或热轧状态交货。

What is channel steel? Channel steel belongs to carbon structural steel for construction and machinery. It is a section steel with complex section, and its section shape is groove shape. Channel steel is mainly used for building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing. In use, it is required to have good welding, riveting performance and comprehensive mechanical properties. The raw material billet for channel steel production is carbon bonded steel or low alloy steel billet with carbon content not exceeding 0.25%. The finished channel steel shall be delivered in hot processing, forming, normalizing or hot rolling state.

槽钢分普通槽钢和轻型槽钢。热轧普通槽钢的规格为5-40#。经供需双方协议供应的热轧变通槽钢规格为6.5-30#；槽钢按形状又可分为4种：冷弯等边槽钢、冷弯不等边槽钢、冷弯内卷边槽钢、冷弯外卷边槽钢；槽钢的材质为Q235A碳素钢。

Channel steel is divided into ordinary channel steel and light channel steel. The specification of hot rolled ordinary channel steel is 5-40#. The specification of hot-rolled flexible channel steel supplied through agreement between the supplier and the buyer is 6.5-30#; Channel steel can be divided into 4 types according to shape: cold-formed equal edge channel steel, cold-formed unequal edge channel steel, cold-formed inner crimping channel steel and cold-formed outer crimping channel steel; The channel steel is made of Q235A carbon steel.

建筑行业的不断壮大，以致更多的建材引入市场，而国标槽钢便是其中的一个，且使用广泛，槽钢主要用于建筑结构、幕墙工程、机械设备、车辆制造、固定盘柜和其它工业结构，槽钢还经常和工字钢配合使用。在使用中要求其具有较好的焊接、铆接性能及综合机械性能。照钢结构的理论来说，应该是槽钢翼板受力，就是说槽钢应该立着，而不是趴着。

With the continuous growth of the construction industry, more building materials are introduced into the market, and the national standard channel steel is one of them, which is widely used. The channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment, vehicle manufacturing, fixed panel and cabinet and other industrial structures, and the channel steel is often used in conjunction with I-beam. In use, it is required to have good welding, riveting performance and comprehensive mechanical properties. According to the theory of steel structure, it should be the force on the wing plate of channel steel, that is to say, the channel steel should be standing instead of lying down.

热轧：就是在再结晶温度以上进行的轧制。相对于冷轧【在再结晶温度以下进行轧制】。槽钢：就是截面为凹槽形的长条钢材。整合起来就是：将槽钢加热到再结晶温度以上，之后进行轧制。热轧能够改善金属和合金的加工工艺性能，金属塑性提高，变形抗力降低。热轧槽钢就是通过加热后轧制出来的形如槽的型材。

Hot rolling: rolling above recrystallization temperature. Relative to cold rolling [rolling below the recrystallization temperature]. Channel steel: a long strip of steel with a groove shaped section. Integration: heating the channel steel above the recrystallization temperature and then rolling. Hot rolling can improve the processing performance of metals and alloys, improve metal plasticity and reduce deformation resistance. Hot rolled channel steel is a groove shaped profile rolled after heating.
