Abstract
The utility model relates to a waste heat recovering device for hot rolling steel, which is characterized by being provided with a heat-insulation cover (1, an air blower (2) is installed on the heat-insulation cover (1), a thermal-collecting tube (3) is sleeved on the air blower (2), the heat-insulation cover (1) is provided with a fixing hole (4) and is fixed on a lifting frame (5), and an adjusting knob (6) is arranged on the lifting frame (5). The utility model has the advantages of high waste heat absorption rate, stable absorption, easily transformed equipment, small investment and obvious economic benefit.
Description
Technical field
The utility model belongs to metallurgy industry hot-strip technical field, relates to a kind of hot-strip waste-heat recovery device.
Background technology
Metallurgy industry is the king-sized industry of energy consumption, and under the environment of high energy consumption, production process produces a large amount of heats, and just there is this phenomenon in rolling process.Rolling process is the process of under the condition of high temperature rolling metal being processed, and production process rhythm is fast, and the waste heat amount is big, the collection difficulty.
The production process of steel rolling production-line is: continuous casting billet (steel billet) is heated to 1250～1300 ℃ in heating furnace (afterburning furnace), enter breaking down, mm finishing mill unit is carried out the rolling of different model, specification, rolling qualified rolled piece temperature of coming out is generally 800 ℃-950 ℃, is cooled to be lower than 80 ℃ and enters collection phase on cold bed.800 ℃-950 ℃ contained heat of rolled piece directly spills in the atmosphere in this course of work, and this part heat accounts for 40～70% of steel rolling heat loss, not only causes energy waste, also contaminated environment.
Summary of the invention
The purpose of this utility model provides a kind of hot-strip waste-heat recovery device.The purpose of this utility model is achieved in that the requirement according to field apparatus characteristics and technology, and the ideal position of steel rolling production-line residual heat collection is collected above cold-bed run-in table and walking beam cooler.The utility model is provided with stay-warm case, and blower fan is installed on the stay-warm case, suit thermal-collecting tube on the blower fan, and stay-warm case is mocked and is provided with fixing hole, and stay-warm case is fixed on the crane, and crane is provided with the adjustment knob, is used for adjusting the height of stay-warm case.Thermal-collecting tube connects waste heat boiler or heat exchanger carries out heat exchange, produces steam and is used for secondary utilizations such as heating, generating.If be used for generating, its generated energy can satisfy 10～30% of steel rolling electricity consumption.The utility model is located at the top of cold-bed run-in table and step rate, and the position height can be regulated, and package unit is installed, dismounting is convenient.Utilize blower fan to carry out exchange heat, the hot blast that sucks is collected by thermal-collecting tube, waste heat is carried out the secondary utilization.This device can be widely used in the place that waste heat is concentrated in the metallurgical technology flow process.
The utility model not only waste heat absorptivity height, absorb steadily, and equipment is easy to transform, small investment, economic benefit is obvious.
