Abstract
The invention relates to a walking beam heating furnace tapping hole, in particular to a walking beam heating furnace tapping hole furnace door frame. The furnace door frame is integrally cast and formed into a reverse T shape through a casting part ZGCr28Ni48W5 to be integrally fixed to a furnace body steel structure, the furnace door frame and a furnace wall are integrated through castable in a pouring mode, and the furnace door frame is prevented from damage caused by collision. The high-abrasion-resistance casting part is adopted for the furnace door frame, the walking beam heating furnace tapping hole furnace door frame can not be damaged by fire when used for a long time at the temperature reaching up to 1300 DEG C or higher, the service life of the furnace door frame is prolonged, and the problems of the blowing-down maintenance and replacement are solved. The actual production proves that the service life of the heating furnace tapping hole furnace door frame is successfully prolonged, the heating furnace blowing-down time is effectively shortened, and in the prior art, production is stopped for at least one day each year so that the furnace door frame can be replaced. If the yield per day is 2000 tons and the profit of each ton is 300 yuan, the created benefit is the product of 2000 and 300, namely, 600,000 yuan per year.
Description
Technical field
The present invention relates to a kind of walking beam reheating furnace tapping hole, particularly a kind of walking beam reheating furnace tapping hole firedoor frame.
Background technology
At present, the heating furnace of clad steel wire factory coupling is heat accumulating type walking beam reheating furnace, and the steel billet motion in walking beam reheating furnace realizes by upper and lower, the anterior-posterior translation action of dynamic beam.The primary feature of high-speed rod walking beam reheating furnace is: side discharging.Steel billet length due to high-speed rod-rolling mill use is long and section is less, and the rolling cycle is long, and steel billet is easily lowered the temperature after coming out of the stove.For reduce red base come out of the stove after temperature drop, ensure the temperature requirement in the operation of rolling, generally adopt side discharge method.The distance that general roughing mill first frame and fire door export is 4-7 meters, and after namely steel billet head enters milling train, afterbody is still at stove inside holding, and whole like this steel billet is basically identical in the stove outer time of staying, and temperature drop is consistent, is conducive to controlling finishing temperature and product size tolerance.This structure is easily run in tapping process at step rate and is caused steel billet deviation phenomenon, will collide tapping hole, and steel billet tapping temperature is up to about 1000 DEG C during the tapping of steel billet sideslip.What former design tapping hole firedoor frame adopted is water but black furnace doorframe, and structure is fixed by bolts on heating furnace framework after making firedoor frame with Q235A steel plate, reduces temperature, to ensure the service life of firedoor frame by middle water flowing cooling.As shown in (Fig. 1).This firedoor frame wearability is bad is is often worn and torn by steel billet and breaks and leak or scaling loss, and need shutdown maintenance or replacing, service life is short.
Summary of the invention
the object of the present invention is to provide one cantapping hole firedoor frame is avoided to wear and tear, be damaged or be burnt and a kind of walking beam reheating furnace tapping hole firedoor frame of shutdown maintenance.
technical solution:
Firedoor frame of the present invention adopts cast member ZGCr28Ni48W5 monoblock cast, is cast into a single-casting, reaches the object extending firedoor frame service life, solves the problem owing to changing firedoor frame and blowing out.
Described firedoor frame is overall shaped into " convex " font.
The top of described " convex " font firedoor frame is arc.
beneficial effect:
The present invention adopts cast member ZGCr28Ni48W5 to make firedoor frame, and firedoor frame and furnace binding entirety are fixed, and finally itself and furnace wall are cast for one by firedoor frame castable.Such tapping hole firedoor frame becomes as a whole and both can not be damaged with heating furnace, because cast member wearability is very high, and Long-Time Service high-temperature reaches more than 1300 DEG C and also can not be burnt, really reach the object extending firedoor frame service life, solve again often because firedoor frame is damaged or scaling loss causes the problem of shutdown maintenance and replacing.
Through producing the actual service life proving successfully to extend heating furnace tapping hole firedoor frame, effectively reduce heating furnace furnace outage time, the time that originally at least stops every year changes firedoor frame.Every day, output was by 2000 tons of calculating.Profit per ton 300 yuan.Creation benefit is: 2000 × 300,=60 ten thousand yuan/year.

Detailed description of the invention
Embodiment
Firedoor frame 1 of the present invention adopts the cast member ZGCr28Ni48W5 integral casting forming that wearability is good, heat resisting temperature is high to be " convex " font, the top curve of described " convex " font firedoor frame 1, and described firedoor frame 1 matches with fire door 2.The firedoor frame 1 of integral casting forming is fixing with furnace binding entirety, finally itself and furnace wall are cast for one by firedoor frame castable.Such tapping hole firedoor frame both can not be worn, and was also not easy to be damaged or scaling loss, really reached the object extending firedoor frame service life.
