Abstract
The invention belongs to the technical field of fire-resistant tools, and particularly relates to a combined type pendulum groove brick. The combined type pendulum groove brick comprises a body, a molten steel groove is formed in the body, openings are formed in the two ends of the molten steel groove, a flow blocking brick is arranged at one end of the body, the flow blocking brick blocks one end of the molten steel groove, the flow blocking brick is divided into a double-layer structure with an inner side and an outer side, the inner side of the flow blocking brick is a high-alumina brick layer, the outer side of the flow blocking brick is a refractory castable layer, and the high-alumina brick layer is arranged on the inner side, close to one end of the flow blocking brick, on the body. The combined type pendulum groove brick is simple in structure, impact resistant performance is improved by beyond two times, and therefore the service life of the pendulum groove brick can be greatly prolonged, manpower replacement is saved, and using cost is reduced.
Description
Technical field
The invention belongs to fire-resistant apparatus technical field, relate in particular to a kind of combined type pendulum groove brick.
Background technology
Pendulum groove brick is to use comparatively general refractory material in the refractory material.Because pendulum groove brick in use, its molten steel is to be fed directly in the molten steel groove.Molten steel directly with the other end that flow into the molten steel groove from an end of molten steel groove, blocked by the baffle brick of the other end then.To be subjected to washing away of molten steel comparatively serious the inboard of its baffle brick place when in use, after using a period of time, the inboard of baffle brick can be worn seriously, thereby makes that often causing pendulum groove brick to use once or several times just is damaged, thereby be forced to roll off the production line, the pendulum groove brick that more renews is being reused.And, because the baffle of baffle brick, have the anti-stream of certain distance after making molten steel be blocked, thereby the molten steel groove has been carried out washing away of another, caused the secondary wearing and tearing.
Summary of the invention
The objective of the invention is to solve above-described technical problem, a kind of combined type pendulum groove brick is provided, its technical scheme is as follows:
A kind of combined type pendulum groove brick, comprise body, it is characterized in that, offer the molten steel groove on the described body, the both ends open of described molten steel groove, one end of described body is provided with the baffle brick, described baffle brick is blocked an end of molten steel groove, and described baffle brick is divided into inboard and outside double-layer structure, and the inboard of described baffle brick is high aluminium brick layer, the outside of described baffle brick is the refractory casting bed of material, and the place, inboard that is positioned at an end of close baffle brick on the described body is provided with high aluminium brick layer.
Optimal way is that the thickness of the high aluminium brick layer on the described baffle brick is 50% of baffle brick thickness.
Optimal way is that the thickness of the high aluminium brick layer on the described body is the 30%-60% of body thickness.
Optimal way is that the length of the high aluminium brick layer on the described body is 50% of body length overall.
Combined type pendulum groove brick provided by the invention when in use, has been provided with high aluminium brick layer in the inboard of baffle brick and the inboard of body.When the end opening of molten steel from the molten steel groove enters, flow into the baffle brick through the molten steel groove then, after the blocking of baffle brick, after being arranged, the anti-stream of part molten steel one segment distance is stored in the molten steel groove.Because baffle brick stopping molten steel, so that the baffle brick has born bigger impulsive force and washing away because the characteristic of molten steel, institute is so that the baffle brick is easy to be worn, but because its inboard is high aluminium brick layer, so effectively prevented from being worn owing to washing away.
Molten steel of the present invention is counter can be caused when flowing wearing and tearing is caused in the body inboard, so can prevent from preferably serious wear from extending working time after using high aluminium brick layer.
The thickness of the high aluminium brick layer on the baffle brick of the present invention is 50% of baffle brick thickness.High aluminium brick layer can the most effective application target that reaches under this thickness, when not influencing baffle brick intensity, makes that farthest improved the service time of pendulum groove brick.
The thickness of the high aluminium brick layer on the body of the present invention is the 30%-60% of body thickness.High aluminium brick layer can the most effective application target that reaches under this thickness, when not influencing body intensity, makes that farthest improved the service time of pendulum groove brick.
The length of the high aluminium brick layer on the body of the present invention is 50% of body length overall.General because the power of anti-stream is less, so being 50% o'clock of length overall, the length of high aluminium brick layer can play better action, when guaranteeing to obtain service time prolonging, also guaranteed intensity and saved material.
The present invention is simple in structure, has improved more than 2 times at impact resistance, therefore can improve the pendulum groove brick life-span greatly, has saved artificial replacing and has reduced use cost.

The specific embodiment
Specify embodiment below in conjunction with Fig. 1 and Fig. 2:
A kind of combined type pendulum groove brick, comprise body 1, it is characterized in that, offer molten steel groove 2 on the described body 1, the both ends open of described molten steel groove 2, one end of described body 1 is provided with baffle brick 3, described baffle brick 3 is blocked an end of molten steel groove 2, described baffle brick 3 is divided into inboard and outside double-layer structure, the inboard of described baffle brick is high aluminium brick layer 4, the outside of described baffle brick 3 is the refractory casting bed of material 5, and the place, inboard that is positioned at an end of close baffle brick 3 on the described body 1 is provided with high aluminium brick layer 4.
Optimal way is that the thickness of the high aluminium brick layer on the described baffle brick is 50% of baffle brick thickness.
Optimal way is that the thickness of the high aluminium brick layer on the described body is the 30%-60% of body thickness.
Optimal way is that the length of the high aluminium brick layer on the described body is 50% of body length overall.
Combined type pendulum groove brick provided by the invention when in use, has been provided with high aluminium brick layer in the inboard of baffle brick and the inboard of body.When the end opening of molten steel from the molten steel groove enters, flow into the baffle brick through the molten steel groove then, after the blocking of baffle brick, after being arranged, the anti-stream of part molten steel one segment distance is stored in the molten steel groove.Because baffle brick stopping molten steel, so that the baffle brick has born bigger impulsive force and washing away because the characteristic of molten steel, institute is so that the baffle brick is easy to be worn, but because its inboard is high aluminium brick layer, so effectively prevented from being worn owing to washing away.
