Description
Technical Field
The utility model relates to the technical field of metal smelting related equipment, in particular to a stainless steel slab transportation heat preservation device.
Background
Stainless steel slabs are products of a continuous casting process (continuous casting plant), and belong to raw materials required for rolling in a hot rolling process (hot rolling plant). In the prior art, the dimensions of stainless steel slabs are generally: 11000mm (length) 1245mm (width) 200mm (height), and the weight was about 22 tons.
After the stainless steel slab is produced, it is transferred from the continuous casting plant to the hot rolling plant. If the transfer distance is short, for example hundred and ten meters, a slab transfer trolley (crown block) is built in a factory room to transfer the high-temperature stainless steel slab (600-700 ℃). If the haul distance is long, for example, hundreds of meters to several kilometers, it is necessary to transport the goods by a haul truck. And transferring the stainless steel plate blank by adopting a transfer truck, wherein the temperature of the stainless steel plate blank needs to be cooled to be lower than 100 ℃ before the stainless steel plate blank can be lifted onto the transfer truck and then transported to a hot rolling mill.
At present, in order to improve the energy utilization rate, the stainless steel slab is required to be directly transported to a hot rolling mill for rolling after being taken off line, and the stainless steel slab is directly installed with a transfer truck to be transported to the hot rolling mill due to high temperature (600 ℃ -700 ℃), so that the following problems exist:
1. the transportation distance is long, and the heat loss in the transportation process is serious. Although the heat loss is small in summer and autumn, the heat loss is still large in overcast and rainy weather and strong wind weather, and in addition, the heat loss is larger in spring and winter when the temperature is lower. Rough estimation, from hot slab loading to transport to hot rolling mill, the heat loss varies from 30 to 50%.
2. The transportation process has large heat radiation, and the heat radiation has large pollution to the environment. The high temperature of the stainless steel slab is a great hazard to pedestrians on the road. In addition, the iron scale on the surface of the stainless steel slab falls off when the slab is blown by wind to cool in the transportation process, and the iron scale is blown into the body or eyes of passersby in some cases. In addition, the falling of the iron oxide scale has great harm to the surrounding environment, such as dust pollution, heavy metal pollution and the like.
