Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain, all belongs to the scope of the utility model protection.
Embodiment one
As depicted in figs. 1 and 2, the side-looking structural representation of a kind of blast furnace discharge yard slag prefabricated iron runner that Fig. 1 provides for the utility model embodiment one, a kind of blast furnace discharge yard slag prefabricated iron runner that Fig. 2 provides for the utility model embodiment one face structural representation.
A kind of blast furnace discharge yard slag prefabricated iron runner that the utility model provides, be fixed on slag iron runner, comprise slag iron and accept section 20 and prefabricated component junction 40, the iron notch place that section 20 is arranged on blast furnace discharge yard accepted by slag iron, slag iron is accepted section 20 and is comprised bottom 61, the first side wall 62 extended by the same side bottom two side direction of bottom 61 and the second sidewall 63, bottom 61, the first side wall 62 and the second sidewall 63 form the first groove 22 extended along its length, the cross section of the first groove 22 becomes U-shaped, prefabricated component junction 40 is extended by the end face of slag iron undertaking section 20 away from iron notch, prefabricated component junction 40 has the second groove 42, second groove 42 has lower arcuate surface and first side of linearly being extended by lower arcuate surface and the second side, the junction of the first groove 22 and the second groove 42 has the 3rd side 50, the lower-most point of the first groove 22 is higher than the lower-most point of the second groove 42.
Concrete, blast furnace discharge yard slag prefabricated iron runner entirety, in similar cuboid, is divided into two portions.Wherein the first part at the iron notch place of corresponding blast furnace discharge yard is that section 20 accepted by slag iron.This section of edge is followed successively by guide part 10, slag iron carrier and alternately portion away from the iron notch direction of blast furnace discharge yard.Wherein slag iron carrier and alternately portion include bottom 61 and the first side wall 62 upwards extended by the two ends of bottom 61 respectively and the second sidewall 63.Wherein the first side wall 62 and the second sidewall 63 are arranged relative to the center line mirror image of bottom 61.From the difference in the portion of replacing, slag iron carrier is that corresponding the first side wall 62 is different with the second sidewall 63 thickness, the side thickness of slag iron carrier is less than the side thickness in alternately portion, and the medial surface of slag iron carrier overlaps with the medial surface in the portion of replacing.In the cross section of the first groove 22 be made up of bottom 61, the first side wall 62 and the second sidewall 63, the internal surface of corresponding first groove 22 becomes U-shaped.Guide part 10 is extended away from the one end in the portion of replacing at slag iron carrier, the upper surface of guide part 10 is downward-sloping inclined-plane, and the height of junction that guide part 10 is connected with slag iron carrier is maximum, and constantly decline along with the direction height away from slag iron carrier, form a descending grade tilted.In the present embodiment, guide part 10 is consistent with the height of slag iron carrier junction and the lower-most point line height of the first groove 22, namely consistent with the height of the bottom line 21 of the first groove.So when normally producing, slag iron is less and more level and smooth by the process resistance that bottom line 21 falls into slag iron flask through the upper surface of guide part 10, swing is slipped in mouth and sluice of the first groove.The upper surface of guide part 10 and the acute angle of horizontal plane are 60 degree in addition.Slag iron is made to be not easy to be bonded at the upper surface of guide part 10.Prefabricated component junction 40 is extended by the end face of slag iron undertaking section 20 away from iron notch, and forms the second groove 42.Because the bottom line 41 of the second groove is lower than the bottom line 21 of the first groove, and the second groove 42 opening maximum width is greater than the first groove 22 opening maximum width, and then forming the 3rd side 50 in the junction of the first groove 22 and the second groove 42, line of delimitation 30 place that the slag iron namely between the first groove 22 and the second groove 42 accepts section and prefabricated component junction forms ladder.In the present embodiment, the second groove 42 has lower arcuate surface, and lower arcuate surface is opening up.That linearly expands in two ends of lower arcuate surface extends upward the first side and the second side.Namely the first side and the second side extend closed rear V-shaped.
Be understandable that, the first groove 22 can also by having the bottom surface of arc and linearly expanding by the bottom surface of arc the first side wall that stretches out and the second sidewall substitutes.
In the present embodiment, the difference of altitude between the bottom line 21 of the first groove and the bottom line 41 of the second groove is 20cm, and the difference of the distance between first groove 22 opening the widest part and second groove 42 opening the widest part is 10cm.
A kind of blast furnace discharge yard slag prefabricated iron runner that the utility model provides, by the second groove 42 of prefabricated component junction being set to be made up of lower arcuate surface and first side of linearly being extended by lower arcuate surface and the second side, the junction of the first groove 22 and the second groove 42 has the 3rd side 50, the lower-most point of the first groove 22 is higher than the lower-most point of the second groove 42, and then change prefabricated component junction shape of cross section, namely the junction between the first groove 22 and the second groove 42 forms ladder, first side and the second side extend and can form the cross section of V-arrangement after converging, so make prefabricated component junction consistent with ramming machine bottom shape, improve the rapping compacting effect of ramming machine, slag iron runner is connected more firm with the joint of prefabricated component, improve the junction firmness of prefabricated component and slag iron runner, and then improve the prefabricated component life-span, the preparation of large component needs multiple mould jointly to complete, and the internal surface of the first groove 22 is kept U-shaped, can not change the mould of manufacture first groove 22 part, and then reduces the design of mould and remodeling workload, reduces improvement cost, ultimate range between the first side wall and the second sidewall is less than the ultimate range between the first side and the second side, making the second groove 42 by adding fixing material, making blast furnace discharge yard slag prefabricated iron runner more fixedly secure on slag iron runner by joint, by the end face in the bottom of slag iron undertaking section 20 away from prefabricated component junction 40, guide part is set, prefabricated component leading portion is made to form a little slope, less slag flowing molten iron can be dirty and can not condense in and slip mouth front end along guide part 10, avoid and form coagulum " beard " on the lower edge of groove, reduce the labour intensity of staff, save the refractory consumption of stokehold, the height of guide part 10 equals height corresponding to the lower-most point of the first groove 22, is convenient to the importing guide part 10 that slag flowing molten iron is more smooth, improves the action effect of guide part 10.
It should be noted last that, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to example, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
