The multi-functional, high-speed spray quenching apparatus for steel tube is characterized in that the low pressure water stream extracted from the water pump can directly turn into the quenching high-speed spray which is suitable for the steel tube, without elevated pool, and the pipe, the accessory for the monitoring, control, etc., are reduced. The utility model has the advantages of simple structure, small ground occupation and low cost, which is in particular to suitable for the rebuilding of old tube rolling production line. The water consumption is one quarter of the intraclass apparatus.
Description
The utility model relates to the multifunctional high speed jet flow quenching device that a kind of steel pipe thermal treatment is used.
External present steel pipe quenching mode has " soak and quench ", " spray is quenched ", " inside and outside linear axis flow quenching (steel pipe does not rotate) ", " spray is quenched+internal rotation axial flow quenching (steel pipe rotation) ", " soak and quench+interior linear axis flow quenching (steel pipe does not rotate) " usually, its corresponding high speed jet steel pipe quenching device all only has the function of finishing a kind of or maximum two kinds of quenching modes, thereby the specification of quenching steel pipe, kind are restricted.On the other hand, high speed jet steel pipe quenching device is provided with the high-level or low-level water pond, and the quenching nozzle adopts straight pipe injector.The water of head-tank is exported by pipeline during quenching, through pump pressurization or valve pressure regulation, from the injector ejection, the steel pipe surfaces externally and internally is quenched again.Water after the quenching is sent into low pool by pipeline, by being pumped into head-tank, recycles behind radiating and cooling.This type of device is owing to there is a very big head-tank of capacity, complicated pipe network and complicated instrument monitoring system, and floor space is wide, on old tube-rolling technique line, arranges almost can't realize, and because the employing straight pipe injector, water loss is very big, quenching cost height.
The utility model provides a kind of multifunctional high speed jet flow steel pipe quenching device, can adopt " soak and quench ", " soak and quench+interior straight line axial flow (steel pipe does not rotate) ", " soak and quench+internal rotation axial flow (steel pipe rotation) ", " interior axial flow (steel pipe rotates or do not rotate) " four kinds of quenching modes respectively according to steel pipe specification kind difference; This have multi-functional high speed jet steel pipe quenching device and can directly use conventional pump setting-out stream, and this conventional pump setting-out circulation becoming high speed jet is carried out multiple mode to steel pipe quench; In addition, save its head-tank and complex grid, make it be particularly suitable for the transformation of old tube rolling production line, and overcome the deficiency of aforementioned steel pipe jet flow quenching device.
The said multifunctional high speed jet flow of the utility model steel pipe quenching device is made up of plumbing pump, pipeline, main valve, variable valve, device for moving and adjusting, unsteady flow speed quenching injector, quenching tank, tube device, hold-down gear, electronic sequence controller, monitoring instrument and circulating water pool.Water pump extracts water coolant through main valve and variable valve from circulating water pool, send into unsteady flow speed quenching injector by pipeline, and unsteady flow speed quenching injector changes the pump pressure current into high speed jet, and steel pipe is implemented to quench.Water flow switch is controlled by main valve.The rotation of steel pipe is controlled by the tube device.The work of whole device is controlled by electronic sequence controller.Various data are by monitoring instrument record and demonstration.Water after the quenching is extracted out by overflow spout or by water pump, sends into circulating water pool through reflux line, recycles.In addition, for draining water hammer, also be provided with by-pass line.
According to aforementioned manner, the main valve of open and close current is made up of valve body, driving mechanism, power transmission part and power input mechanism, and its work situation is by the power input controller controls, and power input controller is controlled by the electronic sequence controller of quenching device then.
Be that unsteady flow speed quenching injector is loaded on the tail end of device for moving and adjusting according to the further solution of aforementioned manner.Unsteady flow speed quenching injector is joined by ashamed shortening pipe of internal diameter and the ashamed expansion short tube of internal diameter and forms, and the throat between two short tubes is an arc transition.The ashamed shortening pipe of internal diameter stub end internal diameter equates with the internal diameter of the pipe outlet on the setting device that is connected.Be furnished with at least three short male members on the inner periphery of the ashamed expansion short tube of the internal diameter of jet flow end, steel tube end part outer scratch nozzle when avoiding quenching.
Advantage of the present utility model is that this device can be with conventional pump setting-out circulation becoming high speed jet, thereby saved head-tank, members such as pipeline and monitoring, control have been reduced, have simple in structure, floor space is little, reduced investment, maintenance workload is few, practical, easy-operating advantage.Particularly water consumption only reaches 1/4th of existing similar quenching device, can significantly reduce steel pipe quenching cost, has tangible economic benefit.
Below in conjunction with accompanying drawing, describe an example of the present utility model in detail.
Fig. 1 is the floor map of multifunctional high speed jet flow steel pipe quenching device.
Fig. 2 is main valve and actuating unit synoptic diagram thereof.Fig. 3 is the actuating unit sectional view.
Fig. 4 is a unsteady flow speed quenching injector sectional view.
With reference to Fig. 1, the water coolant that water pump (1) extracts from circulating water pool (22) enters variable valve (3) through pipeline (2) and delivers to main valve (4), through main valve control, at last from unsteady flow speed quenching injector (6) ejection.Displacement setting device (5) is housed between main valve and injector, and the front and back adjustment is mobile up and down under machinery and electrical equipment control for it, makes injector can satisfy the quenching needs of steel pipe different diameter, length.Before main valve, be provided with safety valve (7), be provided with the by-pass line (8) of adjustable water, to drain water hammer, the supercompression fluid that elimination may occur in the main valve side.
Cross the steel pipe of sizing mill and deliver to adjustable steady arm (10) by transport pipe (9), and a setting gauge electricity of striking part (11).A setting gauge (12) pushes bearing platform and striking master controller electricity part (13), electrical equipment control program work with steel pipe.Steel pipe falls to quenching tank (14) with setting gauge, and pressure tube device (15) compresses steel pipe, and tube device (23) rotates, main valve (4) is opened, nozzle (6) reach is transformed into high velocity flow from the pressure water of hydraulic pipe (2) through unsteady flow speed quenching injector (6), and steel pipe is implemented to quench.Quenching finishes, the reverse work of electrical equipment control program: main valve (4) is closed, and compactor (15) unclamps, and injector moves after (6), and tube pulling machine (16) transfers to steel pipe to go into to collect platform (17).Next root steel pipe quenches and repeats said process.
