It goes through
As a result, the strip line becomes long and the equipment cost increases, and since cooling and heating are repeated, thermal energy is wasted and running costs are high.

取装置である。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a layout diagram of a strip line to which this heat treatment method is applied. A metal strip 1 is fed into a heating chamber 5 from an unwinding device 2 at one end through a guide roll 3 and a group of tension control rolls 4. Heating chamber 5
is a direct-fired heating furnace that performs reductive combustion using a direct-fired burner installed in the furnace, or a radiant tube burner that is installed in the furnace and supplies reducing gas or inert gas to the furnace to create a non-oxidizing atmosphere. The metal strip 1 is heated to a high temperature (450°C to 750°C for copper alloys) at which the desired hardness, tensile strength, elongation, grain size, etc. can be obtained. Reference numeral 6 denotes an air-cooling chamber into which the metal strip 1 is then introduced, and in the air-cooling chamber, a low-temperature non-oxidizing atmospheric gas cooled by a cooler (not shown) is blown onto the metal strip to a temperature of 150°C to 300°C. Cooling.
Next to the air cooling chamber 6 is a water cooling device shown in FIG.
is immersed. The cooling water tank 7 has opposing side walls 8, 8
An inlet/outlet part of the metal strip 1 is provided at the entrance/exit part, and a seal roll 9 is provided at the inlet/outlet part so that the cooling water can be stored at a higher water level than the inlet/outlet part.
A receiving tank 10 is formed in the lower part of the cooling water tank 7 to receive the cooling water overflowing from the cooling water tank 7, and the receiving tank 10 and the cooling water tank 7 are connected by a circulation pump 11, and a cooler 13 is interposed in the piping 12 thereof. , the cooling water in the receiving tank 10 is constantly circulated to the cooling water tank 7. 1
4 is a temperature sensor that detects the water temperature in the cooling water tank 7;
An automatic control valve 15 controls the amount of cooling water flowing to the cooler 13 so that the detected temperature is maintained at a predetermined value.
controlled by. A level switch 16 detects the water level in the water tank 10 and operates an automatic water supply valve 18 provided in the water supply pipe 17 so that the water level is maintained within a certain range. However, a known rust preventive agent is mixed in the cooling water of the lever, and 19 is a concentration sensor that detects the concentration of the rust preventive agent, and 20 is a pipe that supplies the rust preventive agent to the cooling water tank 7, which is installed there. The opening degree of the automatic adjustment control valve 21 is controlled so that the rust preventive concentration in the tank is maintained at the indicated concentration set in the concentration indicating controller 22. 23 is a ringer roll for wiping away moisture. 24 is a drying chamber that blows hot air onto both sides of the metal strip 1; 25 is a group of tension control rolls on the winding side; 26 is a guide roll; and 27 is a winding device.

防錆処理の効率化を達成している。 For this purpose, the metal strip 1, which has been cooled to 150°C to 300°C in the air cooling chamber 6, is then placed in a cooling water tank 7 containing a rust preventive agent, where it is treated with rust prevention and water-cooled to 80°C.
After being cooled down to below, it is dried in the drying chamber 24. In this case, the metal strip 1 is placed in the air cooling chamber 6.
The reason why the metal strip is air-cooled to an intermediate temperature between 150°C and 300°C is to prevent the metal strip from being subjected to thermal stress and deformation such as wrinkles and distortion due to sudden water cooling. In addition, generally known rust preventive agents are more likely to settle at 60℃ to 80℃ than at room temperature. There is.

に有益なものである。 As explained in the above embodiments, the heat treatment method of the present invention involves first cooling a metal strip to 150°C to 300°C by air cooling, and then passing it through cooling water for 80°C.
Since it is possible to perform rust prevention treatment at the same time as cooling by cooling to below ℃, the equipment is highly efficient and the line length is shortened, reducing equipment costs and saving thermal energy. It is beneficial to
