Process is complicated, and on-the-spot practical operation dismounting needs professional tool.
Further, since the steel billet temperature directly contacted with Continuous Casting Rolls is generally at more than 1000 degree Celsius, too high temperature
Making Continuous Casting Rolls that expansion of metal easily occur under degree environment, expansion of metal can cause extending in the axial direction,
Can shorten again after cooling.So will result in whole roller and connect tight in the axial direction, and produce between causing
Raw axial gap, directly affects the service life of Continuous Casting Rolls, causes the stability of continuous casting system and high efficiency poor.
At present, roller cooling generally uses the water-cooled form in centre bore water route.And the diameter of Continuous Casting Rolls is general all at 250mm
Above, center-hole diameter is less than 30mm, and the flow surface distance away from cooling surface is at more than 100mm, at height
Under temperature state for the Continuous Casting Rolls of work continuously, its cooling effect is bad, causes the high temperature resistant and wear-resisting of continuous casting roll surface
Damage performance reduces.
