The understanding of steel plate and the influence of alloy elements in the process of steel plate processing
Jan 15, 2018

Steel plate processing, Concretely, is the processing operation of steel plate material ,To get the desired processing results and finished products.Therefore, steel plate processing, although only four words, but contains a lot of knowledge, below, may wish to come to know and understand the steel processing, so that you can in-depth understanding.

 

Steel plate in the steel plate processing,What is specific?

Steel plate processing, specifically refers to pouring and cooling with molten steel, and then pressed to obtain a flat steel.Therefore, the shape is a flat rectangular shape, and rolling or shearing operations are possible.According to the thickness of the plate to be classified, there are three kinds of thin steel, medium and thick steel plate,The thickness of thin steel plate is not more than 4mm, the thickness of medium steel plate is 4 to 60mm, and the thick steel plate is 60 to 115mm.In addition, if divided according to the type of rolling, it can be divided into two kinds of cold-rolled steel and hot-rolled steel.

 

Influence of alloying elements in steel plate processing

Steel processing, the impact of alloying elements, mainly reflected in the following three aspects.

1.steel plate welding performance

Alloying elements in the steel plate are able to improve the hardenability of the steel and promote the formation of brittle tissue, but it may result in poor weldability.However, if the plate contains a small amount of Ti and V these two elements, you can improve the welding performance of steel.

2.steel plate cutting performance

Plate processing, the quality of its cutting, mainly with the hardness and density of the plate.In general, the hardness range of this material suitable for cutting is 170HB-230HB. And, the cutting performance of carbon steel is better than alloy steel.

Therefore, the right amount of steel in the S, P, Pb and other elements, can improve the cutting performance of the steel.

 

3.Steel plate heat treatment process performance

Steel plate heat treatment, which is also an important process in steel processing and steps,Because of its processing properties reflect the ease of steel heat treatment , and the probability of its occurrence of defects.Therefore, adding manganese, silicon and other elements in the steel can enhance the overheating sensitivity of the steel.In addition, the slow cooling quenching, can avoid the plate heat treatment in the deformation or cracking and other issues.
