目的とするものである。[Detailed description of the invention] The present invention relates to a roll used for a pinch roll installed in a continuous casting machine, and in particular, proposes a roll with a mechanical strength function capable of transmitting torsional torque, especially in a pinch roll having a sleeve. The purpose is to

る。 The rolls used in the pinch rolls that index the slabs cast by the continuous casting machine to advance the casting process are as follows:
The operating conditions are extremely harsh, as the roll surface is in direct contact with the hot slab and the slab is indirectly or directly cooled with cooling water. In particular, rolls that require a drive transmission function require a mechanical strength function greater than that of a non-drive roll by transmitting torsional torque.

耗によるロール表面の損傷はロール寿命短くし、
時にロール折損や鋳片内部割れなどのトラブルを
誘発する原因となる。 When used under such harsh conditions, thermal cracks and abrasion occur on the roll surface, and damage to the roll surface due to these cracks and abrasion shortens the life of the roll.
This can sometimes lead to problems such as roll breakage and internal cracking of the slab.

発生からロールの折損がしばしば発生している。 Conventionally, as a countermeasure against such damage to the roll surface, stainless steel build-up has been constructed, but such build-up parts of stainless steel generally have poor thermal conductivity, so they cannot be easily exposed to heat. Roll breakage often occurs due to the occurrence of cracks.

いては機械的強度上に限界がある。 Sleeve rolls have been proposed as a method to solve the above-mentioned problems with conventional pinch roll rolls. In this case, the sleeve and shaft are usually joined by welding, but
There is a limit to the mechanical strength of joining the sleeve and shaft by welding in order to transmit torsional torque in the drive roll.
しかも、既知の溶接スリーブの場合、連続鋳造

ロール寿命が短かいという欠点も残していた。 Moreover, in the case of known welded sleeves, as long as they are used as rolls for continuous casting, cracks and wear on the roll surface due to heat load are unavoidable, and as a result, the roll life is short.

ルのスリーブロールである。 The present invention is a driving sleeve roll for a pinch roll that drives slabs that are continuously cast in a continuous casting machine to advance casting. By engaging and integrating a shaft with strips machined on its outer periphery, it was possible to drive the shaft and transmit driving force to the slab through the sleeve. This is a pinch roll sleeve roll for continuous casting machines.
