Abstract
The utility model discloses a quenching tank, which comprises a quenching box (1), an incubator (2), a steering roller group (3) and spray pipe group (4); the steering roller group (3) is arranged into many rows in the quenching box (1); the spray pipe group (4) is arranged above the steering roller group (3); the incubator (2) is located under the quenching box (1); wherein the steering roller group (3) is composed of a plurality of steering rollers (3); fall head is set between two adjacent steering rollers (3); the resistance which is formed when a galvanized sheet (5) passes through the quenching box (1) is used as a criterion of the height of the fall head. Through additionally arranging the steering rollers (3) and the spray pipes (4) in the quenching box (1), the cooling capacity of the quenching tank is enhanced; hot water collected from the quenching box (1) by the incubator (2) is delivered to a pretreatment section to clean a steel belt so as to reduce the energy consumption of a hot galvanizing unit.
Description
Technical field
The utility model relates to the refrigerating unit of process section in pot galvanize unit, especially a kind of hardening groove.
Background technology
In Continuous Production Line of Galvanizing by Dipping, the galvanized sheet temperature from zinc pot is out up to 450 °, need be successively through fast cold blast engine, carries out air-cooled and hardening groove and carries out water-cooled, is cooled to 40 ° of left and right just can enter withdrawal straightening machine.In known hardening groove, generally there is following problem: one,, owing to being only provided with two deflector roll and two showers in hardening groove, cooling performance is not obvious; Two, in hardening groove, the water after galvanized sheet heating is not effectively utilized, and has wasted heat energy.
Summary of the invention
For above deficiency, the purpose of this utility model is to provide a kind of hardening groove, hardening box, insulation can, deflector roll group, shower group etc., consists of, and can strengthen greatly the cooling power of hardening groove, rationally utilizes the heat energy of hardening groove.
The technical solution of the utility model is achieved in the following ways: a kind of hardening groove, is comprised of hardening box, insulation can, deflector roll group and shower group; Deflector roll group is lined up many rows in hardening box, shower group is located at the top of deflector roll group, insulation can is positioned at a side-lower of hardening box, it is characterized in that: described deflector roll group is comprised of a plurality of deflector roll, between adjacent two deflector roll, be set with drop, the height of drop forms resistance while passing through hardening box with galvanized sheet and is as the criterion.
In described shower group, variable valve is housed, the water yield of adjustable shower ejection.
The utility model, by increase deflector roll and shower in hardening box, has strengthened the cooling power of hardening groove, and the delivery of collecting in hardening groove by insulation can is broken and cleaned steel band to pre-treatment, has reduced the energy consumption of pot galvanize unit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
By Fig. 1, a kind of hardening groove, is comprised of hardening box 1, insulation can 2, deflector roll group 3 and shower group 4; Deflector roll group 3 is lined up many rows in hardening box 1, shower group 4 is above deflector roll group 3, insulation can 2 is positioned at the side-lower of hardening box 1, deflector roll group 3 is comprised of a plurality of deflector roll, between adjacent two deflector roll, be set with drop, the height of drop forms certain resistance while passing through hardening box 1 with galvanized sheet 5 and is as the criterion, and galvanized sheet 5 was lengthened through the time of hardening boxs 1.Described shower group 4 is equipped with variable valve, the water yield of adjustable shower 4 ejections.There is insulation can 2, be used for collecting the hot water in hardening box 1.
During work, galvanized sheet 5 enters the front temperature of hardening box 1 150 ° of left and right, enters after hardening box 1, passes through successively deflector roll group 3; Simultaneously shower group 4 is sprayed on cold water on galvanized sheet 5, to carry out coolingly, and galvanized sheet 5 temperature that go out hardening box 1 after cooling are 40 ° of left and right; By the water after galvanized sheet 5 heating of high temperature, flow in insulation can 4, be then delivered to pre-treatment section and clean steel band.
The utility model, by the interior increase deflector roll 3 of hardening box 1 and shower 4, has strengthened the cooling power of hardening groove, and the delivery of collecting in hardening box 1 by insulation can 2 is broken and cleaned steel band to pre-treatment, has reduced the energy consumption of pot galvanize unit.
Claims (2)
1. a hardening groove, is comprised of hardening box (1), insulation can (2), deflector roll group (3) and shower group (4); Deflector roll group (3) is lined up many rows in hardening box (1), shower group (4) is located at the top of deflector roll group (3), insulation can (2) be positioned at hardening box (1) below, it is characterized in that: described deflector roll group (3) is by being comprised of a plurality of deflector roll, between adjacent two deflector roll, be set with drop, the height of drop forms resistance while passing through hardening box (1) with galvanized sheet (5) and is as the criterion.
2. a kind of hardening groove according to claim 1, is characterized in that: in described shower group (4), variable valve is housed, the water yield of adjustable shower (4) ejection.
