Cooling device of horizontal type centrifugal-casting machine

Abstract

A cooling mechanism for a horizontal centrifugal casting machine belongs to the technical field of the centrifugal casting machine. The centrifugal casting machine comprises a riding wheel and a stand, wherein the stand comprises a bearing seat and an upper cover of the bearing seat; the riding wheel is arranged on the bearing seat through a bearing and protected by the upper cover of the bearing seat; the cooling mechanism comprises a first ring-shaped cooling flume and a second ring-shaped cooling flume formed in the bearing seat and the upper cover of the bearing seat respectively; the first and the second ring-shaped cooling flumes are separated by a spacer, and a through-hole formed on the spacer causes the first and the second ring-shaped cooling flumes to be communicated with each other; the cooling mechanism further comprises a water inlet interface and a water outlet interface respectively extended on the bearing seat and the upper cover of the bearing seat, wherein the water inlet interface is communicated with the first ring-shaped cooling flume and a water inlet manifold, and the water outlet interface is communicated with the second ring-shaped cooling flume and a water outlet manifold, wherein the first and the second ring-shaped cooling flumes correspond to the bearing. The cooling mechanism has the advantage that the temperature rise of the bearing can be prevented from accelerating, so that the requirement for continuous casting is satisfied.

Description

technical field [0001] The invention belongs to the technical field of centrifugal casting machines, and in particular relates to a cooling mechanism of a horizontal centrifugal casting machine. Background technique [0002] The horizontal centrifugal casting machine used in the roll production industry is usually used for the centrifugal casting of the outer layer of the composite roll blank. Since the wall thickness of the outer layer of the roll is generally less than 100mm and the heat capacity is small, the support wheel of the centrifuge is generally not considered in the design of the centrifuge. Gear train cooling. [0003] When the above-mentioned centrifuge is used for the production of large-scale roll rings, due to the large radial dimension of the roll rings, the thickness of one side is generally greater than 250mm, and the solidification time of the liquid metal in the mold is relatively long, so the long-term heat transfer ( Under the action of heat conducti...

Problems solved by technology

[0003] When the above-mentioned centrifuge is used for the production of large-scale roll rings, due to the large radial dimension of the roll rings, the thickness of one side is generally greater than 250mm, and the solidification time of the liquid metal in the mold is relatively long, so the long-term heat transfer ( Under the action of heat conduction), the supporting wheel bearing of the centrifuge gradually heats up, which limits the centrifugal casting time, that is, it cannot be continuously produced for a long time, and in serious cases, the bearing will be stuck, making the centrifugal casting impossible and affecting the production capacity.
