[0002] With the rapid progress of modern society, the international community's demand for steel is doubling day by day. Continuous heating furnaces are widely used in current rolling production due to their high thermal efficiency. Among them, the walking beam heating furnace is a continuous heating furnace. It is a product of the development from one-stage to multi-stage to adapt to the sharp increase in steel. It is also the most widely used heating furnace.

[0003] A walking-beam heating furnace usually transports materials to a static walking beam in the walking-beam heating furnace through a walking feeding mechanism, and the materials are placed from the walking feeding mechanism onto the static walking beam, on which are placed steel billets to be heated of substantially the same shape and size, and the materials are driven forward by the moving walking beam for heating; after heating, the heated materials need to be transported out of the heating furnace by conveying rollers, at which time the materials on the static walking beam and the moving walking beam need to be lifted up, and then placed on the conveying rollers for conveying; therefore, a material-lifting device is an indispensable device in a heat treatment furnace, and the material-lifting device in the prior art has poor flexibility in lifting and lowering, and is prone to jamming, which affects the overall work efficiency; and when the material-lifting device in the prior art lifts the material, the material-lifting device moves away from the furnace mouth, resulting in heat loss in the furnace body, and frequent material-lifting is likely to affect the insulation effect of the furnace body.
