Due to strip steel specification（Belt steel thickness changes）Change can directly result in the large change of stove heat treatment capacity, when especially there is paper-thin strip production, control cooling section regulation air quantity can be caused automatically adjusts valve opening very little, effectively can not accurately control cooldown rate and cause strip heat treatment performance and template to be affected.To avoid strip cooling under such a extreme running on the lower load out of control, common practices is to set some electric heater units in control cooling section stove（Resistive band or electric heating tube etc.）Carry out the mode to carrying out concurrent heating in burner hearth, equivalent to cooling capacity required under extreme running on the lower load is improved indirectly, so as to avoid cooling system from being operated in caused by extreme underload the problem out of control that cools down, ensure that the accurate temperature controlling that strip cools down under the operating mode.
Above by burner hearth set electric heater unit come to carrying out concurrent heating in burner hearth, so as to avoid cooling system from being operated in caused by extreme underload the problem out of control that cools down, it is technically feasible, it is but supporting to add the relevant equipments such as electric heater unit and control device, not only equipment one-time investment increase, and can additionally increase power consumption during electric heater unit work.
The content of the invention
It is contemplated that the defects of overcoming prior art, there is provided a kind of silicon strip steel heat treatment stove controls cooling section hot blast cooling device, reduces energy consumption, reduces investment outlay.
In order to solve the above-mentioned technical problem, the present invention is realized in：

Silicon steel strip and furnace temperature temperature measuring equipment are located in annealing furnace control cooling section body of heater, and cooling duct top is in annealing furnace control cooling section body of heater；
The entrance of circulating cooling blower fan connects cold blast rate and automatically adjusts valve outlet and the outlet of hot blast automatic switchover valve, the import of the outlet connection cooling duct of circulating cooling blower fan respectively；
The hot-blast outlet of cooling duct connects the import and hot blast automatic switchover valve import that hot blast rate automatically adjusts valve respectively；
Hot blast rate automatically adjusts the outlet discharge hot blast of valve, and cold blast rate automatically adjusts the import suction cold wind of valve；
Temperature detecting module automatically adjusts valve outlet located at cold blast rate and hot blast automatic switchover valve is exported on the mixing duct after parallel connection, and positioned at the entrance of circulating cooling blower fan；
Hot blast rate automatically adjusts valve, cold blast rate automatically adjusts valve and the control mouth of hot blast automatic switchover valve is connected respectively to automatic control system, and furnace temperature temperature measuring equipment and temperature detecting module are connected with automatic control system respectively.
The beneficial effects of the invention are as follows：By the way that normal temperature air medium used by control cooling section to be changed to have to the hot blast of certain temperature problem is difficult to control to improve the intensity of cooling under above-mentioned extreme running on the lower load, so as to ensure that the temperature control of strip cooling under extreme running on the lower load, but the additional electrical energy consumption of electric heater unit is not needed, so Technology for Heating Processing needs were both met, power consumption has been saved again, and reduces the point inspection maintenance workload of electric heater unit and its corollary equipment.
