Description

Mold for inductor manufacturing and method for manufacturing inductor in plating furnace using same {CAST FOR MANUFACTURING INDUCTOR AND METHOD FOR MANUFACTURING INDUCTOR COUPLED ON PLATING FURNACE}

The present invention relates to a mold for manufacturing an inductor mounted in a zinc plating furnace and a method for manufacturing an inductor in a plating furnace using the same.

BACKGROUND ART In general, a plating process for improving physical properties such as oxidation resistance and coating property of a paint is used for steel products.

Among these, the plating facility 1 for the galvanizing process is provided with a plating furnace 2 for storing molten zinc, as shown in FIG. 1, and transports the steel sheet 4 through a conveying means such as a roller. Plating is performed by immersing in the molten zinc contained in the plating furnace (2).

The plating furnace (2) is provided with an inductor (3) connected to the power supply (5) for continuous melting of zinc by induction current. The inductor 3 is configured to circulate molten zinc through the flow path 16 formed therein, and the plating path 2 allows the molten zinc to flow into the flow path of the inductor 3. Is provided.

As shown in FIG. 2A, the conventional inductor 3 is manufactured by the mold 10. The mold 10 has a bushing 12 having a coil mounting hole 12a formed in the mold 11 for appearance appearance having one side open, and a flow path in the opened region of the mold 11 for appearance formation. The forming mold 14 is configured to be mounted by the mold supporting part 15.

In this state, the amorphous (flowable) refractory material 13 is injected through the opening of the mold 11 for external appearance, and the refractory material 13 is cured to produce the inductor body 3a. In this case, the mold for forming the appearance 11 is used as the inductor body 3a.

However, the flow path forming mold 14 used to manufacture the conventional inductor body 3a has an area of the junction surface 13a where the inductor body 3a comes into contact with the port 2a of the plating furnace 2. In order to form the inlet portion 16a in a structure in which the flow path 16 formed to surround the bushing 12 is formed in a larger area than the other area of the mold frame 14 forming the flow path 16. .

On the other hand, the refractory 13 must be mixed with water and undergo a curing process by a hydration reaction, and in order to prevent the durability of the refractory 13 from being degraded, bubbles (A) contained therein must be removed. . Generally, a bubble included in the refractory 13 is removed by using a vibrator, and as shown in FIG. 2B, an area of the flow path forming mold 14 forming the inlet 16a is shown. Bubble A introduced into the lower portion is not removed even by vibration.

In this case, after the refractory 13 is positive, when the flow path forming mold 14 is removed, the pores formed by the bubbles A are exposed to the outside of the inlet 16a or the inlet. It is formed adjacent to the outer surface of 16a. The pores thus formed are a cause of weakening the durability of the refractory 13.

Because of this, a high degree of working skill is required. In the polishing operation of the joining surface 13a, when the polishing marks are generated beyond the required specifications or when the smoothness is not processed to the required specifications, defects such as leakage of molten zinc may occur.

On the other hand, also in this case, since the pores by the bubble A are exposed to the outside of the bonding surface 13a or the pores are formed in an area adjacent to the outer surface, it is a cause of weakening the durability of the refractory 13. .

The pores formed in the state exposed to the interior and / or outer region of the refractory 13 due to the bubble (A) is a concentration of the stress due to the shrinkage of the refractory 13 during the curing or drying process of the refractory 13 It may also form cracks.
