Abstract
The utility model relates to a cooling device, in particular to a cooling device on a Stelmor cooling line, belonging to the technical field of machinery. The cooling device structurally comprises a fan and coolers, and is characterized in that the coolers are symmetrically arranged above an air-cooled roller bed of the fan, each cooler comprises a spray nozzle, wherein the end part of the spray nozzle is communicated with a compressive gas connecting pipe, and a hole is formed on a side face of the spray nozzle to be communicated with a cooling water connecting pipe. The cooling device has the beneficial effects that the strength differentiation on steel mechanical property of a contact point and a non-contact point is reduced, the uniformity of structure and property is improved, water rust on the steel surface is reduced, the generation of an oxide iron sheet is reduced, and the tensile strength and the yield strength of deformed steel bars can be improved.
Description
Technical field
The utility model relates to a kind of cooling device, and the cooling device on especially a kind of Stelmor cooling line belongs to field of mechanical technique.
Background technology
High-speed wire rolling, Laying head with the coil lopping after flat telling on the stelmor conveyor roller, be tiled in the coil on roller-way, rotate transportation forward by table roller, under roller-way, the number formulary Fans upwards to the coil blowing, is forced quenching to wire rod, by the dry number of units of blower fan of change, the wind turbine allocation of the amount of air, stay-warm case is opened quantity and the roller table speed different set changes the intensity of cooling of coil, thereby makes different size, steel grade wire product obtain required tissue and performance.Methods for cooling is divided into according to the needs of different steel grades that standard type is cooling, slow type is cooling and delaying type is cooling.No matter be which kind of methods for cooling coil centre and both sides cooling velocity can be not identical, particularly coil is superimposed has a common boundary a place, heat radiation is slow, different with other position temperature drops, can cause tissue and performance difference, although along with quantity-adjustable " good spirit " device uses, effectively improve middle and both sides allocation of the amount of air, alleviated the difference of temperature drop, but coil exists still with circle tensile strength difference " poor with circle ".Have a common boundary a little and generally also there is 15～20MP in non-tensile strength difference best factory of having a common boundary a place, poor meeting exceeds several times.Some needs are forced cooling steel grade, and the cooling cooling velocity requirement that sometimes do not reach is forced in the below blowing.
The utility model content
The utility model wants the technical solution problem to be: the defective for prior art exists proposes air-cooled line cold
Radiator cooler improves cooling quality.
The utility model is the technical solution problem by the following technical programs, a kind of air-cooled line cooling device, comprise blower fan and cooler, its improvements are: described cooler symmetrical placement is above the air cooling roller-way of described blower fan, described cooler comprises nozzle, the end of described nozzle is communicated with the compressed air tube connector, the lateral opening hole of described nozzle, is communicated with cooling water connecting pipe for water.
Wherein, the aperture of described cooling water hole is 1:4 with the ratio in the aperture of nozzle-end, and cooling water and the compressed air pressure of access are not less than 3MP.
Control valve also is set on described nozzle, can regulates the size of aerosol amount.
Described compressed air tube connector and cooling water connecting pipe for water are communicated with each self-corresponding hole on nozzle by pipe joint.
Described jet hole fixed connecting plate.
Of the present utility model simple in structure, its beneficial effect is: reduce and to have a common boundary a place and non-having a common boundary located intensity difference in steel mechanics performance, improve tissue and performance uniformity, reduce the steel surface scale, reduce scale on surface and generate, can improve tensile strength and yield strength for screw-thread steel.
