The secondary stirring blade is impacted by the impact force carried by the quenching liquid.

[0013] A hot rolling and quenching production process using the hot rolling and quenching equipment for processing 125 mm wear-resistant steel balls comprises the following steps:

[0014] Step 1: Under the separation of the first baffle, the hot-rolled 125mm wear-resistant steel balls are guided into the discharge plate through the feed plate. At the same time, the steel balls are placed in the quenching liquid with a temperature of 20-50°C and quenched by the quenching liquid in the quenching tank.

[0015] Step 2: Turn on the drive motor to drive the rotating rod to rotate, thereby driving the spiral blade to rotate, transporting the steel balls entering the discharge plate obliquely upward, limiting the speed of the drive motor, and quenching the steel balls in the quenching liquid for 5 to 8 minutes. At the same time, turn on the pump body, absorb the quenching liquid through the secondary connecting pipe, and guide it into the primary strip cover plate through the primary connecting pipe and branch pipe, and enter the cavity between the two adjacent secondary baffles through the primary circular hole, thereby quenching the steel balls transported by the spiral blade;

[0016] Step 3: The quenching liquid enters the cavity between the two adjacent sets of secondary baffles, enters the centralized frame plate through the secondary circular hole, the secondary strip cover plate, and the opening, and is sprayed onto the secondary stirring blade located below through the liquid spray port. The impact force carried by the quenching liquid impacts the secondary stirring blade, and the secondary stirring blade is subjected to force, driving the round rod to rotate, thereby driving the primary stirring blade to rotate accordingly. The quenching liquid in the quenching pool is stirred by the secondary stirring blade and the primary stirring blade, thereby improving the fluidity of the quenching liquid. When the quenching liquid in the quenching pool cools the conveyed steel balls through the discharge plate, the secondary baffle, and the secondary mounting plate, the heat distribution of the quenching liquid in the quenching pool is more uniform, thereby improving the quenching effect of the quenching liquid in the quenching pool;

[0017] Step 4: The spiral blade lifts the steel ball diagonally upward for transportation. When the steel ball leaves the quenching liquid and is at the discharge port, it falls to the top of the first-level screen through the discharge port and the guide rack. The quenching liquid discharged along with the steel ball is recovered into the quenching pool through the first-level screen for reuse. The steel ball rolls under the action of the inclined first-level screen, making it easy to collect.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: when in use, after the 125mm wear-resistant steel balls manufactured by the hot rolling equipment are introduced into the quenching pool, the steel balls are transported while the quenching liquid is guided into the cavity between the two adjacent sets of secondary baffles through the added diversion module, thereby increasing the circulation effect of the quenching liquid, ensuring the consistency of the quenching liquid contacted by the transported steel balls and the quenching liquid in the quenching pool, and preventing the quenching effect from being affected by insufficient fluidity of the quenching liquid contacted by the steel balls, and during quenching, the quenching liquid flowing in the cavity between the two adjacent sets of secondary baffles is sprayed onto the secondary stirring blades through the liquid spray port. Under the action of the round rod, the secondary stirring blades drive the primary stirring blades to rotate, thereby stirring the quenching liquid in the quenching pool and improving the fluidity of the quenching liquid. When the quenching liquid in the quenching pool cools the transported steel balls through the discharge plate, the secondary baffles and the secondary mounting plate, the heat distribution of the quenching liquid in the quenching pool is more uniform, thereby improving the quenching effect of the quenching liquid in the quenching pool.

7. A hot rolling and quenching production process using the hot rolling and quenching equipment for processing 125mm wear-resistant steel balls according to claim 5, characterized in that: The following steps are involved: Step 1: Under the separation of the first baffle (4), the hot-rolled 125mm wear-resistant steel balls are introduced into the discharge plate (3) through the feed plate (2), while the steel balls are placed in a quenching liquid at a temperature of 20-50°C, and the steel balls are quenched by the quenching liquid in the quenching tank (1); Step 2: Turn on the drive motor (65) to drive the rotating rod (63) to rotate, thereby driving the spiral blade (62) to rotate, and transport the steel balls entering the discharge plate (3) obliquely upward. The rotation speed of the drive motor (65) is limited so that the steel balls are quenched in the quenching liquid for 5 to 8 minutes. At the same time, turn on the pump body (71) to absorb the quenching liquid through the secondary connecting pipe (76), and guide it into the primary strip cover plate (72) through the primary connecting pipe (75) and the branch pipe (74), and enter the cavity between the two adjacent sets of secondary baffles (61) through the primary circular hole (69), thereby quenching the steel balls transported by the spiral blade (62); Step 3: The quenching liquid enters the cavity between the two adjacent sets of secondary baffles (61), enters the centralized frame plate (87) through the secondary circular hole (84), the secondary strip cover plate (86), and the opening (89), and is sprayed onto the secondary stirring blade (83) located below through the liquid spraying port (810).

The secondary stirring blade (83) is subjected to the force and drives the round rod (81) to rotate, thereby driving the primary stirring blade (82) to rotate accordingly. The quenching liquid in the quenching pool (1) is stirred by the secondary stirring blade (83) and the primary stirring blade (82), thereby improving the fluidity of the quenching liquid. When the quenching liquid in the quenching pool (1) cools the conveyed steel balls through the discharge plate (3), the secondary baffle (61) and the secondary mounting plate (68), the heat distribution of the quenching liquid in the quenching pool (1) is more uniform, thereby improving the quenching effect of the quenching liquid in the quenching pool (1); Step 4: The spiral blade (62) lifts the steel ball obliquely upward for transportation. When the steel ball leaves the quenching liquid and is at the discharge port (66), it falls to the top of the first-level screen (10) through the discharge port (66) and the guide rack (67). The quenching liquid discharged along with the steel ball passes through the first-level screen (10) and is recovered into the quenching pool (1) for reuse. The steel ball rolls under the action of the inclined first-level screen (10) for easy collection.
