Problems solved by technology
Due to the high temperature of the casting slab, the rolling bearings in the foot roll assembly are prone to jamming due to thermal expansion, which seriously affects the transportation of the casting slab, and the steel slag on the casting slab is easy to scatter in the rolling bearings and support seats, causing the foot roll Assembly stuck, high failure rate
Furthermore, in the existing foot roller assembly, the position of the foot roller is difficult to adjust, and the installation requirements are high, and the preload force of the foot roller in the installed state is difficult to adjust separately, which cannot better meet the vibration and arc motion of different workpieces. need

The invention discloses a foot roll assembly for a continuous casting machine, which comprises a foot roll frame, a plurality of roll assemblies are arranged on one side of the foot roll frame, and the roll assembly includes a support base and is arranged on the The foot roller in the middle of the support seat, the foot roller includes a mandrel, rolling bearings arranged at both ends of the mandrel and a bush arranged outside the mandrel, the other side of the foot roller frame is provided with a spray pipeline, the roller assembly also includes a cooling pipeline, a disc spring, an adjustment block and a T-shaped screw, the cooling pipeline is arranged on one side of the support base, and one end of the T-shaped screw is fixed on the foot The other end of the T-shaped screw is connected to the support seat, the disc spring is sleeved on the outside of the T-shaped screw, and the adjustment block is screwed to the foot roller frame. The invention effectively realizes the cooling of the billet, improves the production efficiency, reduces the installation requirements and processing precision, has low failure rate and long service life.
Description
【Technical field】 [0001] The invention relates to the technical field of continuous casting machine equipment, in particular to a foot roller assembly for a continuous casting machine. 【Background technique】 [0002] The foot roller assembly is located under the mold of the continuous casting machine, and it performs a vibrating arc-like motion together with the mold on the vibrating table, supporting and guiding the high-temperature billet, and transporting the billet to the stretching and leveling machine and the conveying roller table. Due to the high temperature of the slab, the rolling bearings in the foot roll assembly are prone to jamming due to thermal expansion, which seriously affects the transportation of the slab, and the steel slag on the slab is easy to scatter in the rolling bearing and the support seat, which in turn causes the foot roll The assembly is stuck and the failure rate is high. Furthermore, in the existing foot roller assembly, the position of the...
