Furnace bottom roller is one of the most important parts of continuous furnace.

Due to the roll of heat-resisting alloy casting billet, cost is high, and the number of roller annealing furnace, infrastructure investment is large, in order to discuss the bottom roller is both reliable and economic structure parameters, this paper USES the bow into the furnace bottom roll material, high temperature of the furnace bottom roll is strong, I mainly creep strength and creep deformation is analyzed.

Annealing bottom roller is the mechanical equipment that makes the charge pass through the furnace. It transports the charge to complete annealing process operation, so as to realize mechanization of production operation and continuity of process flow. Below, the structure characteristics and high temperature strength of the bottom roller, the main part of the roller table, are analyzed:

Furnace bottom roller has the characteristics of high strength, high temperature resistance, small thermal expansion, good chemical stability, high temperature performance stability, non-deformation, smooth and fine surface, good wear resistance, etc., is an ideal substitute product for traditional graphite carbon sleeve and ceramic coating roller.

Under the premise of high temperature strength, the diameter of furnace bottom roller should be smaller, so as to save precious metals and reduce the weight of equipment. Furnace bottom roll at more than 80 temperature in the furnace and load to 0 ℃ under the action of the rotation, and by the burden of the mechanical damage of regret, therefore, furnace bottom roll material has high temperature strength and oxidation resistance, the structure of the roller Jane is a centrifugal casting of hollow cylinder, two sets of roller box end weld on it, the two end shaft and welding on the roller shaft, roller Jane's thin wall to the axial heat to heat resistance, within the roller to roll end joint 12 by chain transmission.
