Abstract
The invention discloses a method for replacing a stopper rod on line for a tundish and a cross arm structure for replacing the stopper rod. The cross arm structure is characterized in that: a movable cross arm is connected on a fixed cross arm, and the end of the movable cross arm is provided with a fork head for blocking the stopper rod. The method for replacing the stopper rod on line mainly comprises the following steps of: after the movable cross arm and the stopper rod are assembled across, baking the movable cross arm and the stopper rod in an oven, and then moving the movable cross arm and the stopper rod to the lower part of a hanger; driving the tundish to a sizing nozzle to adopt sizing control; hoisting the used stopper rod out together with the movable cross arm by using the hanger; hoisting the baked stopper rod into the tundish together with the movable cross arm, and settling the bottom end of the stopper rod to the nozzle of the tundish; and adjusting the stopper rod to control the casting current of the tundish, and screwing down bolts for connecting the movable cross arm and the fixed cross arm to finish on-line replacement of the stopper rod. The service lives of the stopper rod and the nozzle can be matched, the casting cost is reduced, the service life of the tundish for casting high-quality steel can reach 72 hours under the condition of complete stopper rod control, and low-cost casting of the high-quality steel can be realized.
Description
Technical field
The present invention relates to the method for the online replacing stopper of a kind of tundish and the cross arm structure of replacing stopper.
Background technology
But pulling rate control mainly contains stopper formula, metering nozzle formula and stopper reducing mouth of a river formula in the present domestic continuous casting production.The stopper formula can be poured into a mould the high-quality molten steel but the cost height; Lower but the difficult cast high-quality molten steel of metering nozzle formula cost; But stopper reducing mouth of a river formula combines the advantage of stopper formula and metering nozzle formula, but stopper was suspended from and is subjected to washing away of molten steel eddy current much more serious than the mouth of a river in the molten steel when its weak point was cast, make the stopper life-span be lower than the mouth of a river life-span, realize that the tundish bag of pouring into a mould the high-quality molten steel is controlled by the stopper life-span in age, consequently pours into a mould cost and can not further be reduced.
Summary of the invention
The present invention solves the existing existing technical problem of technology, and the method for the online replacing stopper of a kind of tundish and the cross arm structure of replacing stopper are provided.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: the method for the online replacing stopper of a kind of tundish is: the jaw of a, movable transverse arm and the end of stopper fork are put into the baking box baking after putting and assembling; B, baked stopper and movable transverse arm are moved to the suspender below together with go-cart; C, tundish is squeezed into metering nozzle adopt the control of sizing formula; D, will will hang out in the lump together with movable transverse arm with the stopper of crossing with suspender disassembling from fixing transverse arm with the movable transverse arm of stopper; E, with suspender baked stopper is hung in tundish together with movable transverse arm, the stopper bottom is deposited to the place, the mouth of a river of tundish, and movable transverse arm is arranged on fixedly on the transverse arm; F, adjust stopper to controlling the tundish beam, tighten the connection activity transverse arm and the fixing bolt of transverse arm, online replacing stopper is finished.
The cross arm structure of the online replacing stopper of a kind of tundish comprises fixedly transverse arm, connects on the described fixedly transverse arm movable transverse arm is set, and the end of movable transverse arm is provided with the jaw that is used for the holding stopper.
As preferably, the connecting portion of described movable transverse arm and the fixedly connecting portion superimposed setting up and down of transverse arm, and movable transverse arm connecting portion be arranged on fixing transverse arm connecting portion above.
As preferably, also be provided with handle on the connecting portion of described movable transverse arm, the jaw base portion of movable transverse arm is provided with the pin of spacing stopper.
The present invention is designed to detachable structure with transverse arm, the termination of movable transverse arm holding stopper, again stopper is lifted above the tundish together with movable transverse arm, movable transverse arm has played the effect of counterweight, hand-held handle can about adjust together with movable transverse arm the stopper bottom is deposited to comparatively effortlessly in the place, the mouth of a river of bag, adjust behind the tundish beam movable transverse arm is fixed on fixedly on the transverse arm just passable.
Stopper is about 40 hours in service time on the tundish, the tundish upper nozzle life-span can reach more than 72 hours, the present invention compares the mode of other three kinds control pulling rates, stopper and mouth of a river life-span are complementary, fully excavate anti-material potentiality, reduce the cast cost, the tundish life-span of cast high-quality steel can reach 72 hours (the domestic mouth of a river life-span that can reach) under the situation that is entirely the control of stopper formula, can realize low-cost cast high-quality steel.Characteristics such as it is reasonable in design, simple in structure, workable that the present invention has.

The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, technical scheme of the present invention is described in further detail.
Embodiment: referring to Fig. 1-3, the present invention connects movable transverse arm 2 is set on fixing transverse arm 1, the end of movable transverse arm 2 is provided with the jaw 4 that is used for the holding stopper, the connecting portion of movable transverse arm 2 and the fixedly connecting portion superimposed setting up and down of transverse arm 1, and movable transverse arm connecting portion be arranged on fixing transverse arm connecting portion above, use bolt 3 that both are fixed together, the connecting portion of movable transverse arm 2 is provided with handle 5, and the jaw base portion of movable transverse arm 2 is provided with the pin 6 of spacing stopper.
The method of the online replacing stopper of tundish of the present invention is: the jaw of a, movable transverse arm and the end of stopper fork are put into the baking box baking after putting and assembling; B, baked stopper and movable transverse arm are moved to the suspender below together with go-cart; C, tundish is squeezed into metering nozzle adopt the control of sizing formula; D, will will hang out in the lump together with movable transverse arm with the stopper of crossing with suspender disassembling from fixing transverse arm with the movable transverse arm of stopper; E, with suspender baked stopper is hung in tundish together with movable transverse arm, the stopper bottom is deposited to the place, the mouth of a river of tundish, and movable transverse arm is arranged on fixedly on the transverse arm; F, adjust stopper to controlling the tundish beam, tighten the connection activity transverse arm and the fixing bolt of transverse arm, online replacing stopper is finished.
At last, should be pointed out that above embodiment only is the more representational example of the present invention.Obviously, technical scheme of the present invention is not limited to the foregoing description, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
