What are the contents of packaging steel strip slab processing?
Answer: Slab processing includes cleaning and inspection. In order to facilitate the management of the 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 cleaning device is installed on the finishing line of blooming and continuous casting. The cold slab mechanical flame cleaning device and manual flame cleaning device can be installed offline in the blooming and continuous casting workshop, and can also be installed in the hot rolled plate Billet library.
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 artificial flame cleaning tools. However, with the increase in the amount and the high temperature technology of the slab The implementation of manual cleaning can no longer be completed. For this purpose, a method of automatic deburring has been developed and applied. The methods of cleaning burrs include mechanical cleaning with shovel and oxygen flame cleaning. Now most of them use mechanical cleaning, and they are carried out online 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 meet the needs of HCR and HDR, a hot surface defect detection device has been developed. Hot surface defects of slabs are inspected by 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. are used to detect fine surface defects using cold slab penetration testing.
