What are the content packaging steel strip slab processing?

What are the content packaging steel strip slab processing? A: the slab processing including clean up and check the content of the two. To facilitate management of the slab cleaning work is generally in the continuous casting workshop, also some install the cleaning equipment in hot rolled slab of the rolls. ( 1) Clean up. Mainly by flame slab of cleaning a way, for stainless steel, high alloy steel and so on also have adopt grinding wheel. Scarfing there are three ways: hot slab machinery scarfing, cold slab and manual fire flame cleaning. Hot slab mechanical scarfing devices installed in the rolling and continuous casting finishing line, at the beginning of the cold slab mechanical device and manual fire flame cleaning device can be installed in the offline in the blooming mill, continuous casting workshop, also can be installed in hot rolled slab library. Flame cutting burrs generated in continuous casting slab ( Slag adhesion on the back of the slab) , first by the workers, the use of artificial scarfing tools to clean up, however, with the increase of the amount and the implementation of the high temperature slab technique, artificial cleaning has been unable to complete, for the development and application of the automatic cleaning method of burr. Deburr method including the mechanical cleaning method and oxygen flame spader is two kinds of cleaning method, now the majority of the mechanical cleaning method is adopted, and it is online in the continuous casting production. ( 2) Check. The slab surface condition, before, during and after the traditionally are made by the workers in cutting visual inspections with the naked eye, however, in order to improve the inspection accuracy and meet the needs of the HCR, HDR, hot surface defect detection device is developed. Hot surface defects of slab, detection device with the use of probe coil eddy current flaw detection device and use of spontaneous or lighting light optical detection device. Stainless steel, high alloy steel such as frost to tiny surface defect detection, adopt the method of cold slab penetration testing experiment.
