Description
Technical field
It is the present invention relates to iron and steel metallurgical industry rolling technical field, in particular to a kind of for the slitting of hot strip longitudinal direction
Production method and application.
Background technique
Currently, trimming and slitting are generally realized by following two mode in the cold state for steel plate strip point, the
A kind of mode is gas flame cuttiug mode, and cutting speed is slow, and offline mode is usually taken in when cutting, and the strip cutting of different-thickness is logical
The length of flame or replacement nozzle are overregulated to realize, this kind of mode has many advantages, such as that equipment is simple, investment amount is few, but the disadvantage is that
Production efficiency is low, and quality of tube cutting influences uncontrollable etc. vulnerable to heat affected area；The second way is to be cut by bilateral scissors+subdivision
Mechanical combination cutting mode, cut mode have it is roll-turning, two kinds of disc type, wherein rolling cut mode can realize thickness≤50mm plate
The cutting on line of band, disc approach are only able to achieve thickness≤25mm strip cutting on line, mechanical relative to gas flame cuttiug mode
The advantages of cutting mode is that shear fracture is high-quality, high-efficient, but the disadvantage is that the device is complicated, money amount is big.With regard to band steel bar point
Speech, thickness≤20mm or less strip generally use the strip slitting line for carrying out slitting in the cold state, this kind of mode is current band
The major way of steel bar point.
The required forming temperature of continuous hot bending shaping machine set access panel band is between 600 DEG C -900 DEG C, the plate of raw material plate band
Temperature can also be realized using the waste heat for rolling back plate band by reheating of the strip after cold.But the reheating mode of strip
Not using the waste heat for rolling back plate band, become the present age of mainstream in energy-saving, production cost control, hence it is evident that be not WeiLai Technology
The main flow direction of development.Using the waste heat for rolling back plate band, the continuous hot bending under realization is hot is formed, by rolling process and hot bending work
Sequence seamless connection is got up, and is avoided the secondary energy sources waste reheated after strip is cooling, will is the emerging developing direction of future development.
Summary of the invention
