Description

Technical Field

[0001] The utility model relates to the technical field of steel billet transportation, in particular to a sliding heat-insulating cover device for a train. Background Art

[0002] During the production process of steel enterprises, if steelmaking and rolling are carried out in the same plant, the billets produced by steelmaking can be transported to the rolling mill by means of roller conveyors, cranes, etc. However, for some steel enterprises that have multiple plants or where steelmaking and rolling are located far away from each other, most of them use trains for transportation. During the transportation by train, the billets are affected by the ambient temperature, rainy and snowy weather, and the wind cooling caused by the train transportation, which causes the surface temperature of the billets to drop significantly. There is a large temperature difference between the periphery and the center of the billets, which can easily lead to quality problems such as cracks at the edges and corners during the rolling process. The lowered billet temperature also increases the gas consumption of the heating furnace. If an insulation cover is directly added to the train flatbed car and is lifted and lowered by the crane, the lifting and lowering height of the insulation cover cannot be met in some places where the height of the plant is limited, and the insulation cover cannot be lifted and lowered by the crane. In addition, the lifting and lowering by the crane increases the workload and the time for loading and unloading the billets.

[0003] Therefore, it is necessary to develop a kind of train sliding heat-insulating cover device to solve the problems referred to above. Utility Model Content
