Abstract
The utility model discloses a copper pipe molding core rod for crystallizer and belongs to the field of core rod. The copper pipe molding core rod for crystallizer comprises a core rod main body, wherein a metal layer is arranged on the external layer of the core rod main body; the metal layer is a chrome plating layer; and the core rod main body is made of No.45 steel. Compared with the prior art, the copper pipe molding core rod for crystallizer, provided by the utility model has the advantages that the processing difficulty is reduced, the cracks are difficult to occur in forging process, the service life is prolonged and the production cost is lowered. Therefore, the copper pipe molding core rod has a high application value.
Description
Technical field
The utility model relates to a kind of plug, especially a kind of crystallizer copper pipe moulding plug.
Background technology
Present employed crystallizer copper pipe moulding plug, plug is a single layer structure, plug adopts 40Cr steel alloy material to make the hardness height, difficulty of processing is big, forges to occur defective easily, occurs crackle easily, life-span is short, and 40Cr steel alloy price is higher, has increased production cost.At present, good solution is not also arranged.
The utility model content
Technical assignment of the present utility model is to provide a kind of crystallizer copper pipe moulding plug at above-mentioned deficiency of the prior art, this crystallizer copper pipe moulding plug has and has reduced difficulty of processing, be not easy to occur defectives such as crackle when forging, increased service life, reduced the characteristics of production cost.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises the plug body, and the skin of described plug body is provided with a metal level, and described metal level is a hard chromium, and described plug body is No. 45 steel matter.
Described metal layer thickness is 0.06-0.08mm.
Crystallizer copper pipe moulding plug of the present utility model is compared with prior art, have following outstanding beneficial effect: plug is a double-decker, internal layer plug body adopts No. 45 steel matter to make, the skin of plug body is a hard chromium, reduce difficulty of processing, be not easy to occur defectives such as crackle when forging, increased service life, reduced production cost, characteristics such as easy to use.
Description of drawings
Accompanying drawing 1 is the structural representation of crystallizer copper pipe moulding plug;
Description of reference numerals: 1, plug body, 2, metal level.
The specific embodiment
With reference to explaining below 1 pair of crystallizer copper pipe moulding plug work of the present utility model of Figure of description.
Crystallizer copper pipe moulding plug of the present utility model, its structure comprises plug body 1, and the skin of described plug body 1 is provided with a metal level 2, and described metal level 2 is a hard chromium, promptly at outer electrodeposit one deck hard chrome of plug body, described plug body 1 is No. 45 steel matter.
The thickness of described metal level 2 is 0.06-0.08mm.
When using plug, outer layer metal layer 2 hard chromium of plug body 1 contact with the crystallizer copper pipe inboard, because hard chromium hardness is higher, can not damage the plug body 1 of plug internal layer.Internal layer plug body 1 is No. 45 steel matter, and hardness ratio 40Cr steel alloy is little, the workpiece cracking phenomena occurs forging Shi Buhui, and price is lower, has reduced production cost.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
Claims (2)
1. crystallizer copper pipe moulding plug comprises the plug body, it is characterized in that: the skin of described plug body is provided with a metal level, and described metal level is a hard chromium, and described plug body is No. 45 steel matter.
2. crystallizer copper pipe moulding plug according to claim 1 is characterized in that: described metal layer thickness is 0.06-0.08mm.
