The furnace roller specially used for the batch bottom spheroidizing annealing furnace is composed of a tube-shaped roller body and shaft ends closely matched at both ends, and a welding pile and a through-hole pin are arranged between the two. The roller body is centrifugally cast with heat-resistant steel, and the shaft head is made of alloy structural steel or heat-resistant steel forged and finished. Therefore, under 800 ℃ working conditions, it can carry 10 tons. It is resistant to intermittent loads, high temperatures, and strong bending resistance.

A furnace roller used in a batch-type spheroidizing annealing furnace with a roller bottom is composed of a roller body (5) and shaft ends (1, 7) at both ends thereof, and is characterized by a roller body (centrifugally cast in heat-resistant steel) ( 5) In the form of a tube, each end is tightly equipped with a shaft head (1, 7) made of alloy structural steel or heat-resistant steel forged and finished, and the roller body (5) nozzle and shaft head (1, 7) ) There is a weld deposit (2).
