Problems solved by technology
At present, the quenching oil pool is mainly used for quenching and tempering of rolls, which has many disadvantages: (1) the quenching oil is expensive, and the quality will deteriorate and age when used, and the economic investment is large; (2) the operation requirements are high, and the occurrence of The risk of fire is extremely high; (3) Oil and gas volatilize and pollute the working environment of the workshop, which is harmful to human health; (4) The cooling rate is limited, which affects production efficiency, and when the oil temperature is higher than a certain temperature, it will not meet the quality requirements
(5) The cooling rate cannot be adjusted according to the process needs

Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0017] Such as figure 1 Shown: a new type of cold roll spray quenching equipment, including a base 7, a pair of supporting rollers are installed on the base 7 of the steel structure to place the roll 8, one of which is the driving roll 9, the other is the passive roll 3, and the driving roll 9 Connect the power system assembled by the motor 12 and the reducer 11 through the chain 10; adjust the distance between the two supporting rollers by adjusting the position of the passive roller 3, so as to meet the needs of supporting rollers 8 of different specifications; A group of water spraying devices are respectively installed on both sides of the roller system. The water spraying device includes a main water pipe 5 installed on the bracket. The water pressure gauge 4 is installed on the main water pipe 5, and the water distribution pipe 4 is correspondingl...

The invention discloses a novel jet quenching device for cold rolls, which comprises a base (7), a driving roll (9) and a driven roll (3), wherein the driving roll (9) and the driven roll (3) are used for placement of a roll (8). The novel jet quenching device is characterized in that water jetting devices located on the outer sides of the driving roll (9) and the driven roll (3) are arranged on the base (7), each water jetting device comprises a main water pipe (5) arranged on a bracket, and the main water pipe (5) is communicated with a nozzle (1) facing the roll (8) through a branch water pipe (2) connected with the main water pipe (5). According to the invention, through arranging the water jetting devices on both sides of the driving roll and the driven roll, the jet quenching device for cold rolls takes water as a cooling medium, therefore, the jet quenching device has the advantages of safety, no toxicity, harmlessness to the human body, and no pollution to the environment, and the jet quenching device is safe in use, and does not cause fire disasters; and by adjusting the parameters such as pressure, flow and the like of jet quenching water, a controllable cooling process can be realized, and the jet quenching device has the characteristics that the cooling speed is high and the roll subjected to hardening and tempering is good in toughness, therefore, the jet quenching device is suitable for being popularized and applied.
Description
technical field [0001] The invention relates to a novel cold roll spray quenching equipment, which is mainly used for spray quenching and cooling of cold roll quenching and tempering heat treatment. Background technique [0002] Roll quenching and tempering heat treatment is an important process in the roll manufacturing process, the purpose is to improve the microstructure and improve the strength and toughness of the roll. At present, the quenching oil pool is mainly used for quenching and tempering of rolls, which has many disadvantages: (1) the quenching oil is expensive, and the quality will deteriorate and age when used, and the economic investment is large; (2) the operation requirements are high, and the occurrence of The risk of fire is extremely high; (3) Oil volatilization pollutes the working environment of the workshop, which is harmful to human health; (4) The cooling rate is limited, which affects production efficiency, and when the oil temperature is higher ...
