The movable beam bottom in the walking-beam type heating furnace adopts skirt and water seal groove cooperation mounting means to reach sealed effect, and the water yield that will have certain water level in the water seal groove guarantees to carry out the water seal to interior flame and flue gas of stove. In the use process of the water seal tank, the corrosivity of the liquid level of the internal water level causes the local thinning of the steel plate of the water seal tank, and even leakage points appear. The start and stop of the walking beam furnace require long time, and the shutdown treatment is difficult to be carried out due to leakage points of the water seal tank under the condition of very heavy production task. But the condition is serious, which can cause the production stoppage and maintenance, and has great influence on the production. Therefore, the stable operation of the water seal tank of the walking beam furnace is particularly important.
Therefore, a new method is urgently needed to solve the problem of leakage repair of the water seal tank.
Disclosure of Invention

The technical scheme adopted by the invention is as follows:
a method for treating leakage points of a water seal tank of a walking beam furnace is characterized by comprising the following steps:
1) preparing a bolt, two metal pressing plates and a rubber pad aiming at a leak point, wherein the two metal pressing plates are divided into an inner pressing plate and an outer pressing plate, and the centers of the two metal pressing plates are provided with through holes with the diameters equal to the diameters of the bolts;
2) the screw rod penetrates through the through hole of the inner pressure plate, so that the bolt head is tightly attached to the inner pressure plate and the inner pressure plate are welded together through electric welding;
3) cutting a through hole at the center of the rubber pad, wherein the diameter of the through hole is smaller than that of the bolt, and inserting a screw rod into the through hole of the rubber pad to enable the rubber pad to be tightly attached to the inner pressing plate;
4) cutting a circular hole with the diameter equal to that of the bolt at the leakage point of the water seal tank steel plate by using gas welding gas;
5) the screw rod provided with the inner pressing plate and the rubber pad is quickly loaded from the leakage point of the steel plate from the inner side of the water seal groove, the outer pressing plate is loaded on the screw rod on the outer side of the water seal groove, and finally the screw rod is fastened through the nut.
The thickness of rubber pad is 5 mm.
The area of the rubber pad is larger than that of the metal pressing plate.
And in the step 2), the welding between the bolt head and the inner pressure plate is full welding.
The thickness of the metal pressing plate is 6 mm.
The metal pressing plate is made of stainless steel.
In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that: the method for sealing the leakage point of the water seal tank steel plate through the bolt and the metal pressing plate and the rubber pad arranged on the bolt is simple and efficient in process and convenient to operate, and can effectively avoid the problem that the edge part of the existing commonly-adopted welding leakage repairing process is secondarily cracked. The water seal tank leak source can be quickly and effectively treated in a short time, production is not affected, and the problems that an overhaul period is not available, the water seal tank steel plate becomes thinner locally due to corrosion, and normal welding cannot be carried out after the leak source appears are solved.
