Hot rolled angle steel is a common metal profile，haveLType section，Widely used in architecture、bridge、Fields such as mechanical manufacturing。The following is comprehensive knowledge about hot-rolled angle steel：
one、definition
Hot rolled angle steel refers to the process of heating a steel billet to a high temperature，Angular steel processed through rolling technology。Its cross-section is usually an equilateral or non equilateral right angled triangle。
two、Production process
The production process of hot-rolled angle steel mainly includes the following steps：
raw material preparation：Select high-quality steel plates or billets as raw materials，Ensure that its chemical composition and surface quality meet the requirements。
heating：Feed the raw materials into the heating furnace，Heat to the appropriate rolling temperature，To improve its plasticity and processability。
rolling：Rolling the heated raw materials through a rolling mill，Make angle steel to form the desired cross-sectional shape。
cooling：Cooling treatment of rolled angle steel，Usually using water or air cooling，To fix its shape and enhance its strength and hardness。
Subsequent processing：As needed，Cutting angle steel、bore、Surface treatment and subsequent processing。
