Abstract
The utility model provides a blast furnace front slag iron runner, which is provided with a protective groove for pouring high-temperature-resistant cement at the bottom of the slag iron runner groove and on the inner wall, and the side wall of the protective groove is gradually thickened from top to bottom. Because the high-temperature resistant cement protection groove is additionally arranged on the iron slag runner, the width of the iron slag runner edge and the thickness of the groove are increased, the problem that the cover plate is not tightly covered or covered is avoided, the safety of walking personnel on the cover plate is ensured, the high-temperature resistance of the runner edge and the iron slag runner is improved, the use and maintenance period of the iron slag runner and the runner edge can be relatively prolonged, and the maintenance and replacement cost is reduced. Meanwhile, the safety performance of the iron slag groove is improved, and even if the iron slag groove has slag leakage and iron leakage accidents, the accidents caused by the falling of the iron slag can not be enlarged.
Description
Technical field
The utility model belongs to the ironmaking equipment field, particularly a kind of preceding slag iron runner of the State of Blast Furnace of protecting groove that has.
Background technology
Along with the progressively maximization of blast furnace, stokehold slag iron runner has been taked totally-enclosed form basically, during ordinary production, is stamped cover plate above the slag iron runner, thereby makes stokehold operation field safety and cleaning more.Yet, find in the actual production process that breakage very easily appears in the bank that cover plate is accepted in stokehold slag iron runner upper end, cause the cover plate lid tight even do not cover.And because the bank breakage brings certain threat for site operation personnel's personnel safety.And the nearly all large blast furnace of analogue all exists, even the way of taking annual overhaul to change, repair bank, its duration of service is also not long.
Study carefully its slag iron runner bank damage reasons, the one, the bank size is narrow, and the bank width of design is 90-110mm, washes away wearing and tearing down for a long time comparatively fast at the slag flowing molten iron; The 2nd, slag iron runner sidewall adopts the normal concrete cast, and under secular high bake, concrete strength descends, and causes bank very easily damaged.If damaged bank can not in time be found and handle, just may cause the slag iron runner that iron takes place to leak and leak the slag accident, cause immeasurable loss.
Summary of the invention
The purpose of this utility model is exactly at the problems referred to above, provides a kind of simple, safe and reliable, durable, can guarantee in last walker person's safety, avoids taking place slag iron runner and leaks the preceding slag iron runner of State of Blast Furnace that slag leaks the iron accident.
For reaching this purpose, the utility model has been taked following solution:
Slag iron runner before a kind of State of Blast Furnace is characterized in that, at the protection groove that the bottom of trench and the inwall of slag iron runner groove is provided with the high temperature resistant cement cast, protection groove sidewall is progressive additive from top to bottom.
Described protection groove sidewall upper edge thickness is 180-230mm, with the sidewall thickness of bottom land joint be 280-330mm, bottom land thickness is 200mm.
Positively effect of the present utility model is:
Owing to set up high temperature resistant cement protection groove at the slag iron runner; the one, increased slag iron runner bank width relatively, even protection groove upper edge is damaged, can not influence the cover plate operation yet; avoid the problem that the cover plate lid is not tight or do not cover, guaranteed the personnel's that on the cover board walk safety.The 2nd, increased the thickness of slag iron runner groove, improved the especially resistance to elevated temperatures of slag iron runner of bank, can prolong the use and the maintenance cycle of slag iron runner and bank thereof relatively, reduce maintenance and replacement charge.The 3rd, improved the safety performance of slag iron runner, leak the iron accident and also can not make the extension that causes the accident down of slag iron even slag takes place to leak slag iron runner.
Description of drawings
Accompanying drawing is a slag iron runner sectional view before the State of Blast Furnace.
Among the figure: casting house platform 1, protection groove 2, Ditch cover board 3, prefabricated component 4, backfill seam 5, slag iron runner groove 6.
Embodiment
The section form of slag iron runner groove 6 is a regular rectangle before original State of Blast Furnace, the inboard of slag iron runner groove 6 upper edges is left a breach and is promptly taken the bank of putting cover plate 3, after cover plate 3 covers, the top common casting house platform 1 that formed of cover plate 3 and slag iron runner groove 6.In addition, as the main runner of molten iron, also be provided with prefabricated component 4 in the mid-way of slag iron runner groove 6.
The utility model is to have set up a protection groove 2 in slag iron runner groove 6, and protection groove 2 is to adopt the high temperature resistant cement cast to form.The section form of protection groove 2 is: outer wall is upright, inner wall belt is gradient, promptly protect groove 2 sidewall progressive additive from top to bottom.Specifically be of a size of: protection groove 2 sidewall upper edge thickness be 200mm, with the sidewall thickness of protection groove 2 bottom land joints be that 300mm, protection groove 2 bottom land thickness are 200mm.
Claims (2)
1. slag iron runner before the State of Blast Furnace is characterized in that, at the protection groove that the bottom of trench and the inwall of slag iron runner groove is provided with the high temperature resistant cement cast, protection groove sidewall is progressive additive from top to bottom.
2. slag iron runner before the State of Blast Furnace according to claim 1 is characterized in that described protection groove sidewall upper edge thickness is 180-230mm, with the sidewall thickness of bottom land joint be 280-330mm, bottom land thickness is 200mm.
