Since cooling controlling and rolling controlling process can improve the mechanical property of Bar Wire Product product, the work(of some alloying elements in steel is substituted
Can, in the case of national standard specification is met, the production cost of steel can be reduced, while the raising of the performance such as intensity can subtract again
Steel usage amount in Shaoshi work, meets energy-saving and emission-reduction, the requirement of low-carbon environment-friendly, therefore cooling controlling and rolling controlling process production Bar Wire Product product
Technology have broad application prospects.
Certain steel mill has increased Bar Wire Product controlled rolling and controlled cooling system newly by technological transformation.After what the controlled rolling and controlled cooling system was related to rolls
Controlled cooling device, is 3 sections of control cold water storage cisterns of arrangement after the rack of roll line end, there is 4 section cooling ducts, preceding 3 section in every section of control cold water storage cistern
Long cooling duct is used for positive cooling (along rolling direction), and the short cooling duct of rear 1 section is purged for opposite direction.But in actual life
In production, quickly forward rolled piece is usually wiped in the short cooling duct entrance of its head contact touches or directly hits conduit and cause to block up
Steel, causes completely to stop in emergency.
The stifled steel accident of processing not only influences product quality, occur among rolling waste product, and labor strength it is big, it is necessary to
Gas flame cuttiug, draw steel, or even to dismantle water tank and internal cooling conduit, time and effort consuming, serious to reduce milling train operating efficiency.
Utility model content
Technical problem to be solved in the utility model is, for above-mentioned rolled piece existing in the prior art during moving ahead
Often collide or hit the problem of short cooling duct causes stifled steel and then causes operating efficiency low, there is provided a kind of controlled rolling and controlled cooling system
Novel cooling device in system.
Technical solution is used by the utility model：
Novel cooling device in a kind of controlled rolling and controlled cooling system, including the length sequentially coaxially set along rolled piece direct of travel are cold
But conduit, short cooling duct, are provided with horn mouth body between long cooling duct and short cooling duct, horn mouth body it is small
End is coaxially fixed on short cooling duct periphery, the big end of horn mouth body towards long cooling duct and with long cooling duct interval
Certain distance, the minimum diameter of the big end of horn mouth body are less than the internal diameter of short cooling duct.
According to such scheme, the small end of the horn mouth body is fixed on short cooling by four screws being evenly distributed
On conduit.
According to such scheme, plane residing for the maximum gauge of the big end of the horn mouth body and the outlet of long cooling duct
Axial distance be 30mm.
According to such scheme, the angle of taper of the big end of the horn mouth body is 32 °.
Having the beneficial effect that acquired by the utility model：
1. the utility model, by setting horn mouth body between long cooling duct and short cooling duct, rolled piece is leaving
It is not to be directly entered short cooling duct after long cooling duct, but enters short cooling after the guiding for passing through horn mouth body
Conduit, avoids stifled steel accident, reduces hand labor intensity, improves milling train operating efficiency；
2. horn mouth body is screwed on short cooling duct, by horn mouth sheet when horn mouth body wear is serious
Body retightens after being rotated by 90 °, and can be continuing with, and safeguards that replacement cost is small, convenient for disassembly and assembly, time saving and energy saving.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram；
Fig. 2 is the structure diagram of horn mouth body；
In figure：1- horn mouth bodies, 11- small ends, 12- big ends, 2- screws, 3- long cooling ducts, the short cooling ducts of 4-.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, present embodiments provide novel cooling device in a kind of controlled rolling and controlled cooling system, including along rolled piece row
Long cooling duct 3, the short cooling duct 4 sequentially coaxially set into direction, sets between long cooling duct 3 and short cooling duct 4
Horn mouth body 1 is equipped with, the small end 11 of horn mouth body 1 is coaxially fixed on short 4 periphery of cooling duct, horn mouth body 1
Big end 12 is towards long cooling duct 3 and spaced apart with long cooling duct 3, in the minimum of the big end 12 of horn mouth body 1
Footpath is less than the internal diameter of short cooling duct 4.
From the point of view of from Fig. 1, the direct of travel of rolled piece is from right to left.
The structure diagram of horn mouth body 1 is as shown in Figure 2.The structure of horn mouth body 1 is common knowledge：Horn mouth sheet
The small end 11 of body 1 is cylinder ring, and the big end 12 of horn mouth body 1 is round platform ring, and round platform ring refers to shape in truncated cone-shaped, inside
Hollow out into the ducted body for waiting wall thickness.
Big end 12 and small end 11 are coaxial, at the minimum diameter of big end 12 (in namely Fig. 1, the left side outlet of big end 12
