Abstract
The utility model discloses an induction quenching cooling water well for a cold roll. Spiral vanes are arranged on the inner wall around the water well, so that the water flow moving direction is opposite to the rotary direction of the cold roll. A water pump for accelerating water to flow circularly is installed at the bottom of the water well. The induction quenching cooling water well for the cold roll provided by the utility model has the advantages that after the spiral vanes are installed, and water is pumped by the water pump at the bottom of the water well, so that water on the upper part of the water well moves downward. In the downward moving process of cooling water, inclined separators around the water pool agitate the downward moving water flow like the spiral vanes, so as to generate vortex movement opposite to the rotary direction of the cold roll, the relative moving speed of water flow and the surface of the roll is increased to generate a greater flushing force, so as to inhibit generation of bubbles in the cooling process, accelerate cracking of bubbles and improve the cooling capacity, and the purpose of increasing the depth of hardening zone and improving the hard uniformity is realized.
Description
Technical field
Cooling technology when the utility model relates to a kind of forging steel cold roll induction quenching, especially a kind of vortex cooling well that improves cooling power, increase depth of hardening zone and uniformity of hardness in the forging steel cold roll quenching process.
Background technology
Along with the raising of cold-rolling mill performance requriements, the relevant technologies index request of cold roll is also more and more higher, and depth of hardening zone and uniformity of hardness are two important indicators wherein.
Depth of hardening zone is relevant with hardening capacity and the heating means of material itself, simultaneously with method of cooling very important relation is arranged also, can reach suitable heat penetration by various heating means, if but do not have suitable cooling technology, be difficult to realize that the quenching of fully enough degree of depth changes, it is excessive to obtain desirable depth of hardening zone and hardness, so method of cooling is very large on the quench-hardened case impact.
Uniformity of hardness is relevant with homogeneity of ingredients and heating uniformity, with cooling much relations are arranged also, at initial stage in process of cooling, because roller temperature is very high, water coolant is on every side vaporized rapidly and is formed one deck steam bubble, be attached to roller surface, surface, this place of roll and water coolant are on every side separated, thereby have influence on cooling performance, cause this place cooling deficiency, lower hardness, uniformity of hardness descends.So method of cooling is very large on the impact of uniformity of hardness.
The present type of cooling mainly be exactly cold through water-jet spray after, static water cooling in well, produce several continuously after, along with the WIH temperature rise, affected cooling performance, thereby affected depth of hardening zone.
The utility model content
The technical problems to be solved in the utility model provides a kind of cooling well that increases the cold roll depth of hardening zone and improve its uniformity of hardness.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of cold roll induction quenching cooling well, its gordian technique is: it is that inwall is equipped with the direction of motion screw-blade opposite with the cold roll sense of rotation that can make current around well, is equipped with in the bottom of described well for the water pump that promotes that water cycle flows.
Described screw-blade is the dividing plate that is obliquely installed.
The beneficial effect that adopts technique scheme to produce is: the utility model inwall around the cooling well is installed the screw-blade of certain angle, it is tilt clapboard, and the pumping for water pump by well bottom, the water on well top is moved downward, in the water coolant folding process, tilt clapboard around the pond produces the stirring action of similar rotary fan to the current that move down, impel the eddying motion of its appearance and roller rotational opposite direction, increase the speed of relative movement of current and roller surface, produce larger scouring force, thereby breaking of steam bubble accelerated in the generation of the steam bubble in the inhibition process of cooling, improves cooling power.Reach the purpose that increases depth of hardening zone and improve uniformity of hardness.Under same heating condition, adopt this vortex cooling well can increase depth of hardening zone 2-5 mm, uniformity of hardness reaches≤2HSD.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to accompanying drawing 1 and accompanying drawing 2, the utility model is that inwall is equipped with the direction of motion screw-blade 3 opposite with cold roll 1 sense of rotation that can make current around well 2, is equipped with in the bottom of described well 2 for the water pump 4 that promotes that water cycle flows.Described screw-blade 3 adopts the dividing plate that is obliquely installed.
The beneficial effect that produces behind employing the utility model is described below by embodiment:
Embodiment 1:
Be the cold roll that A factory produces, material 9Cr2Mo, roll diameter ￠ 380mm requires hardness of roll body requirement 90HSD～96HSD, quench-hardened case 〉=13mm, uniformity of hardness≤3HSD.
Before adopting this cooling well technology, the anatomical results quench-hardened case of cold roll is 12mm, and uniformity of hardness is 4HSD; Under same heating condition, it is rear to adopt this cooling well to cool off, and quench-hardened case reaches 15mm, and uniformity of hardness is 2HSD, successful.
Embodiment 2:
Be the cold roll that B factory produces, material MC3, roll diameter ￠ 460mm requires hardness of roll body requirement 92HSD～95HSD, quench-hardened case 〉=20mm, uniformity of hardness≤3HSD.
Before adopting this cold water well technology, the anatomical results quench-hardened case is 17mm, and uniformity of hardness is 3HSD; Under same heating condition, behind the vortex cooling technology of employing this cooling of whirlpool well, quench-hardened case reaches 21mm, uniformity of hardness 2HSD, successful.
Embodiment 3:
Be the cold roll that C factory produces, material MC5, roll diameter ￠ 600mm requires hardness of roll body requirement 92HSD～96HSD, quench-hardened case 〉=30mm, uniformity of hardness≤3HSD.
Before adopting the cooling technology of this cooling well, the anatomical results quench-hardened case is 27mm, and uniformity of hardness is 3HSD; Under same heating condition, adopt the vortex cooling technology of this cooling well after, quench-hardened case reaches 31mm, uniformity of hardness 2HSD, successful.
After we adopted this cooling well to carry out the vortex cooling through a large amount of evidences, the quench-hardened case of cold roll and uniformity of hardness all obviously improved, and have obtained good effect.
