What are the contents of packaging steel strip slab processing?
Answer: Slab processing includes cleaning and inspection. In order to facilitate the management of slab cleaning work is generally carried out in the continuous casting workshop, and some cleaning equipment is installed in the hot-rolled slab warehouse.
(1) Clean up. The cleaning of slabs is mainly by flame cleaning. For stainless steel, high alloy steel, etc., grinding wheels are also used.
There are three methods of flame cleaning: hot slab mechanical flame cleaning, cold slab mechanical flame cleaning and manual flame cleaning. The hot slab mechanical flame treatment device is installed at the beginning
On the finishing line of rolling and continuous casting, cold slab mechanical flame cleaning device and manual flame cleaning device can be installed offline in blooming and continuous casting workshops, or in hot-rolled slab warehouse.
The burrs (the slag adhering to the back of the slab) produced during flame cutting of continuous casting slabs were initially cleaned by workers using manual flame cleaning tools. However, as the amount of HCR increases and the slab becomes hotter The implementation of technology can no longer be done manually. For this reason, a method of automatic deburring has been developed and applied. Method package for deburring
includes two kinds of mechanical cleaning method using shovel and oxygen flame cleaning method. At present, most of the mechanical cleaning method is adopted, and it is carried out on-line in continuous casting production.
(2) Check. The surface condition of the slab is traditionally inspected visually by workers before and after cutting. However, in order to improve the inspection accuracy and adapt to HCR,
In the need of HDR, a hot surface defect detection device was developed. Hot surface defect detection devices for slabs include eddy current flaw detection devices using probe coils and optical flaw detection devices using self-luminous or illuminating light.
Stainless steel, high-alloy steel, etc. need to be tested for fine surface defects, the cold slab penetration test method is used.
