Description
Technical field
A kind of heater is the utility model is related to, particularly belongs to a kind of on-line heating for being used for cold rolling or warm-rolling working roll
Device.
Background technology
At present, for siliceous 6.5% and the high-silicon steel of the above, or the inductile difficulty deformable metal plate such as magnesium alloy, in room
When being rolled under temperature, because strip resistance of deformation is big, therefore it is difficult to deform, causes side to split seriously, and also easily split among steel band
Line, have a strong impact on product quality and qualification rate.To solve this problem, in actual processing production, people typically take heating base
Rolled after material.But when strip thinner thickness, due to the temperature difference between board temperature and roll be present, heat stream when causing to roll
To roll, decline board temperature, strip plasticity is deteriorated.Therefore, the mode heated to roll is taken to be solved.At present
The method of heated steel roll has following several：
1) flame heated roll：After being heated to certain temperature to roll using naked light, rolled after withdrawing from heater
System.But this method can not accomplish that on-line continuous heats；Naked light flame temperature is high and flame non-uniform temperature everywhere, roll heating
It is uneven.And can not on-line heating roll, cause rolling when roller temperature it is unstable.
2) hollow roll is used：Roll is heated using deep fat or electrically heated rod.The heating of this mode energy on-line continuous and
Temperature control, but roll needs especially processing, and hollow result causes roll stiffness intensity to decline, roll is variable when roll-force is excessive
Shape.As patent publication No. be respectively CN1745902A, CN101249512A, CN103599941A, CN104588412A and specially
The documents such as sharp grant number CN203648989U.
3) electromagnetic induction heating：Induction coil is housed on roll both sides, by the magnetic field of alternation roll produce be vortexed into
Row heating, electromagnetic induction heating firing rate is fast, and temperature stabilization is adjustable.But when rolling exception occurs and broken belt occurs, hold
Coil is easily caused to be damaged, and equipment investment is larger, stability is poor.Such as patent publication No. CN102430570A and CN103658189A
Deng document.
