Wear-resistant steel ball quenching equipment

Abstract

The invention proposes wear-resistant steel ball quenching equipment. The wear-resistant steel ball quenching equipment comprises a quenching pool, a first ball conveying pipe, a second ball conveying pipe, a cooling box and a conveying device, wherein a first end of the first ball conveying pipe is arranged at the outer side of the upper side of the quenching pool, and a second end is connected with a first end of the second ball conveying pipe; the second ball conveying pipe is arranged at the bottom of the quenching pool; a steel ball outlet is formed in a second end of the second ball conveying pipe; multiple dust outlet pipes are arranged at the lower part of the second ball conveying pipe along a steel ball output direction in sequence, and penetrate through the bottom of the quenching pool; the dust outlet pipes at the front section and the back section of the second ball conveying pipe are respectively communicated with a first liquid colleting part and a second liquid collecting part; a first filter and a second filter are respectively arranged in the first liquid collecting part and the second liquid collecting part; the first liquid collecting part and the second liquid collecting part are respectively communicated with the cooling box; the cooling box is communicated with the quenching pool; and one end of the conveying device is arranged below the steel ball outlet, and the other end is arranged at the outer side of the upper side of the quenching pool. The wear-resistant steel ball quenching equipment is uniform in quenching, easy for through hardening and fast in speed, obviously improves the quenching effect, and promotes the quenching efficiency.

Description

technical field [0001] The invention relates to the technical field of wear-resistant steel ball processing, in particular to a wear-resistant steel ball quenching equipment. Background technique [0002] Wear-resistant steel balls need to be quenched and tempered at a certain temperature to improve their strength, hardness, wear resistance, fatigue strength and toughness. The quenching effect has a great influence. If the temperature of the quenching liquid is too high, the cooling rate will decrease significantly, and the quenching effect will not be achieved. It is very necessary to use cooling equipment to cool the quenching liquid. [0003] After quenching, the impurities on the surface of wear-resistant steel balls will be mixed into the quenching liquid. The large particles will sink to the bottom of the quenching pool under the action of gravity, and the small particles will float or suspend in the quenching liquid under the action of buoyancy, affecting the quenchin...

Problems solved by technology

[0002] Wear-resistant steel balls need to be quenched and tempered at a certain temperature to improve their strength, hardness, wear resistance, fatigue strength and toughness. The quenching effect has a great influence. If the temperature of the quenching liquid is too high, the cooling rate will drop significantly, and the quenching effect will not be achieved. It is very necessary to use cooling equipment to cool the quenching liquid.

[0003] After quenching, the impurities on the surface of wear-resistant steel balls will be mixed into the quenching liquid. The large particles will sink to the bottom of the quenching pool under the action of gravity, and the small particles will float or suspend in the quenching liquid under the action of buoyancy, affecting the quenching liquid. The quality and temperature transfer and distribution of the material will affect the quenching effect of the next batch of wear-resistant steel balls
