2015，Strong implementation of national policies on environmental protection and energy，Regarding the domestic coal industry，steel，electricity，cement，High energy consuming enterprises such as glassPropose strictRectification requirements.In the steel industry, due toThe government's regulation of the market has led to a decline in profits in the steel industry, causing steel companies to enter a bottleneck stage. Various enterprises have begun to pay attention to their own energy-saving measures, seeking solutions to energy waste and reducing raw material lossesNew technologies and innovationsmethod due tobeforeThe steel market has strong sales and prices are expected to rise，No one values the process of smelting and heatingOxygen controlProblem causingformlessThe loss of economic benefits. becauseforReduce residual oxygen in the furnace during the heating process of steel billets1%namelyCan reduce the oxidative layer0.2%，At present, the domestic steel industry adopts the use of residual oxygen in the furnace6%~8%The Burning，Oxidized cortex in3About millimeters，The average yield of steel billets is93%~95%左右，If the oxygen content of combustion in the furnace is controlled within1%Left and right, the oxide layer can be reduced to1Within millimeters, the yield of steel billets has been increased to98%The above. Example of enterprise economic benefits:1The price per ton of steel billet is2000Yuan, finished product rate before oxygen control93%Oxygen content inside the furnace6%，1After being heated in a furnace, one ton of steel billet can only1860Yuan,7%Raw material oxidation layer waste treatment, based on market oxidation layer per ton200Yuan Suan, scrap income14yuan，Intangible losses of enterprises126Yuan. After controlling the oxygen level, the oxygen content in the furnace is1%Left and right, the yield rate is98%Enterprise losses36Yuan. Save for businesses90Yuan. Adding energy savings together can yield multiple benefits120About yuan. This inconspicuous number is a considerable amount for enterprises with an annual output of tens of millions of tonsofprofit. In2008When I visited steel enterprises in Tangshan City and Sichuan Province in the past year to promote this concept to high energy consuming enterprises, it did not receive recognition and attention.becauseforThe price of steel in the market is one price per dayThe soaring, eachaenterpriseNot accepted and valuedThe concept of small energy savings and yield benefits. With the current weakness of the steel market, oversupply and the implementation of environmental policies，Bringing pressure to high energy consuming enterprises, it is necessary to improve outdated process modes, reduce energy consumption, and increase profits.

201412moonby AustraliaNOVATECH takes the leadThe application project of combustion mathematical models has been launched in Tangshan CitysomeAfter a month of on-site renovation, data collection, mathematical parameter modification, and establishment of the fuel air ratio function module, the tunnel type stepper heating furnace was piloted2015year1moon9The daily zero morning online operation was successful.

The operating conditions are shown in on-site photos:
1) Oxygen display chart

2) Oxygen content6.07%Oxidation scale spark

3) Surface oxide layer on the steel ingot when it is discharged from the furnace

4) The oxygen content in the furnace decreases，Furnace temperature rise

5) The oxygen content in the furnace decreases，Reduction of oxide scale sparks

6) Oxygen level approaching1%More significant changes in time

7) Oxygen level approaching1%time，Oxidation scale sparks disappear

8) There are no traces of oxide layer on the surface of the steel ingot after it is fired

9) When the combustion ratio reaches *，Overlapping of mathematical function curves.

10) The oxygen probe is inserted into the furnace in a horizontal straight insertion manner，Achieve synchronization with changes in gas content inside the furnace

The entire system has been successfully connected online，Will be activated2015High energy consuming furnaces in ChinachangeBuild projects that utilize real-time sensing technology inside the furnace to achieve energy-saving and environmental protection goals.
