Disclosed is a controlled cooling and controlled rolling method for control over a bearing steel wire carbide network, the method comprising rapidly rolling a bar into a wire with a specified specification, subjecting same to spinning so as to give a scattered roll, with the final rolling temperature being controlled to be 780ºC-880ºC, and the spinning temperature being controlled to be 750ºC-850ºC; subjecting the continuous scattered roll to on-line controlled cooling through EDC water bath isothermal quench cooling, with the cooling speed being controlled to be 2.0 ºC/s-10 ºC/s, and the final cooling temperature being controlled to be 620ºC-630ºC; cover-adding slow cooling same after the EDC water bath isothermal quench cooling, with the temperature when the scattered roll is taken out from a cover being controlled to be 400ºC-500ºC; and collecting the roll after the slow cooling, and air cooling same to normal temperature. By subjecting a disc roll, subjected to controlled rolling, to controlled cooling through the method of EDC water bath isothermal quench cooling and cover-adding slow cooling, precipitation of a carbide in the cooling process can be effectively inhibited, a non-equilibrium microstructure is obtained, a small-strip-shaped or hemispheric carbide is formed, and finally, a carbide network is controlled.
