Abstract
The utility model relates to a kind of foundry goods protective tube locating device, and it comprises several foundry goods protective tube, protective tube link rod and protective tube positioning seat; Described protective tube link rod is laterally fixedly connected on several foundry goods protective tube; Described protective tube positioning seat is fixedly installed on the foundry goods protective tube bottom being positioned at end positions.Adopt foundry goods protective tube locating device of the present utility model, control the position shift momentum of protective tube after cooling stave casting pouring in process of cooling, improve the position dimension precision of protective tube, improve the work-ing life of cooling stave.This device neither affects protective tube along with the normal contraction of foundry goods in process of cooling, effectively can control again to this contraction, makes it finally to reach required dimensional precision.Foundry goods protective tube positioning device structure of the present utility model is simple, and input cost is less, easy for installation, can Reusability.
Description
Technical field
The utility model belongs to metallurgical casting industry, particularly a kind of locating device of foundry goods protective tube.
Background technology
Along with work-ing life brought up to 15 years from 10 years by blast furnace, bring up to again 20 years recently, the requirement of user to blast furnace is more and more higher; in order to reach long lifetime blast furnace; also improve constantly the technical requirements of cooling stave foundry goods, wherein protective tube spacing is an important indicator, and reason is as follows:
1, in order to improve the intensity of last furnace shell, the perforate on furnace shell is constantly reduced, and some last furnace shell perforates have reduced to protective tube diameter+15mm.
2, can occur to cause due to shell deformation protective tube to be subject to furnace shell extruding on blast furnace, produce distortion and even cause water pipe to ftracture, leak.Therefore more and more higher to the concentricity requirement of cooling stave protective tube and furnace shell.
In order to meet these requirements, improve constantly the technical requirements of cooling stave, wherein the positional precision of protective tube becomes at present ± 3.5mm from ± 6.5mm, and this is trend of the times, is the demand in market, and Ye Shi cooling stave production firm needs the technology improving and grasp.
In view of this, person skilled in art is devoted to the locating device researching and developing a kind of foundry goods protective tube, to improve the position dimension precision of protective tube.
Summary of the invention
Task of the present utility model is to provide a kind of foundry goods protective tube locating device, it solves the problem existing for above-mentioned prior art, controls the position shift momentum of protective tube after cooling stave casting pouring in process of cooling, to improve the position dimension precision of protective tube.
Technical solution of the present utility model is as follows:
A kind of foundry goods protective tube locating device, it comprises several foundry goods protective tube, and it also comprises protective tube link rod and protective tube positioning seat;
Described protective tube link rod is laterally fixedly connected on several foundry goods protective tube;
Described protective tube positioning seat is fixedly installed on the foundry goods protective tube bottom being positioned at end positions.
Described protective tube positioning seat semicircular in shape shape, is fixedly mounted on foundry goods protective tube lower outside and encloses.
In order to improve the position dimension precision of foundry goods protective tube, foundry goods protective tube locating device of the present utility model mainly controls its position shift momentum after cooling stave casting pouring in process of cooling.Control by common process method; displacement variation is generally within ± 6.5mm; and increase a kind of locating device by the utility model at foundry goods protective tube extension; be arranged in combination on protective tube; neither affect protective tube along with the normal contraction of foundry goods in process of cooling; effectively can control this contraction again, make it finally to reach required dimensional precision.Locating device of the present utility model can take off after product manufacturing completes, and can reuse.
After using foundry goods protective tube locating device of the present utility model; the protective tube position dimension precision of stretching out foundry goods can reach ± 3.5mm within the scope of; namely casting accuracy is increased to CT10 level from CT12 level; meet the concentricity requirement of cooling stave foundry goods protective tube and furnace shell completely; improve the work-ing life of cooling stave; also the setting accuracy requirement improved constantly is met, convenient installation.
Foundry goods protective tube positioning device structure of the present utility model is simple, and input cost is less, simultaneously can Reusability.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of foundry goods protective tube locating device of the present utility model.
Reference numeral:
1 is foundry goods protective tube, and 2 is protective tube link rod, and 3 is protective tube positioning seat.
Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
Referring to Fig. 1, the utility model provides a kind of foundry goods protective tube locating device, and it forms primarily of several foundry goods protective tube 1, protective tube link rod 2 and protective tube positioning seat 3.
Protective tube link rod 2 is laterally fixedly connected on several foundry goods protective tube 1, and several foundry goods protective tube 1 is joined together securely.
Protective tube positioning seat 3 is fixedly installed on foundry goods protective tube 1 bottom being positioned at end positions, namely in single foundry goods protective tube 1 bottom being positioned at end positions of the foundry goods protective tube 1 joined together, fixedly mounts protective tube positioning seat 3 respectively.Protective tube positioning seat 3 can semicircular in shape shape, is fixedly mounted on the outer gusset of foundry goods protective tube 1 bottom.
Adopt foundry goods protective tube locating device of the present utility model, control the position shift momentum of protective tube after cooling stave casting pouring in process of cooling, improve the position dimension precision of protective tube, improve the work-ing life of cooling stave.This device neither affects protective tube along with the normal contraction of foundry goods in process of cooling, effectively can control again to this contraction, makes it finally to reach required dimensional precision.Foundry goods protective tube positioning device structure of the present utility model is simple, and input cost is less, easy for installation, can Reusability.
Certainly, those skilled in the art in the art will be appreciated that, above-described embodiment is only used to the utility model is described, and be not used as restriction of the present utility model, as long as in spirit of the present utility model, the change, modification etc. of above-described embodiment all will be dropped in the scope of the utility model claim.
