Cutting Process of Continuous Casting Billets
The cutting process of continuous casting billets is a very important process in the overall production. It directly affects the surface quality, size accuracy, internal structure and mechanical properties of the parts after casting. The goal of cutting is to ensure that the cutting section is continuous and not cut, and the cutting of the billet is smooth and not causing tearing.
Continuous casting slabs are usually cut by sawing or shearing before they are sent to various workshops for processing. Sawing is mainly used for mild steel, low alloy structural steels and non-heat-treatable alloys. The quality of the cutting depends on the accuracy of the saw blade, the quality of the lubricant and the quality of the operator.
Shearing is mainly used for stainless steel, heat-treated alloy steels, non-ferrous alloys and castings. This method requires a lot of tools and the cutting quality depends on the geometry of the blade and the quality of the cutting surface. It is used to cut off large amount of billets and can process a large amount of billets at a time, greatly improving the utilization rate of resources.
When cutting is performed, it is important to observe whether the cutting section is continuous without breaks. It is important to pay attention to the problems of cutting force, slag on the blades and unintentional heating of the cut surfaces. The saw blades and shearing blades should be regularly checked and replaced in time, so that the cutting can be more accurate and the wear will be reduced. The quality of the cutting depends on the selection and maintenance of the cutting tool, the power of the cutting tool and the quality of the cutting personnel.
In summary, cutting is an important process in the overall production process of continuous casting billets. It plays a very important role in the production of excellent parts. All people involved in the cutting process should pay close attention to the selection and maintenance of cutting tools, maintenance of cutting condition, and adjust and use cutting equipment accordingly.
