Abstract

PURPOSE:To manufacture a tubular mold of a large size having a good electromagnetic agitating effect by working grooves for cooling water in a material of high mechanical strength, joining flat plates having good heat conductivity on the worked surface thereof to form flat plates clad with two layers and bending the same to a tube-like shape. CONSTITUTION:Grooves 2 for cooling water are beforehand worked on a mold body1 consisting of a material of high mechanical strength such as carbon steel or special steel, and a flat plate 3 of 1-50mm. thickness of Cu or Cu alloy of good heat conductivity is joined by diffusion welding or the like on the worked surface thereof, whereby flat plates 4 clad with 2 layers are manufactured. After the two layered plates 4 are bent with a press to make constituting members (a)-(e), the members are conbined as shown by A-E. The terminals 8 which are the combined parts are closed by diffusion holding or bolting to form the members into a tube-like shape. Thus the manufacture of the large-sized tubular mold having >=250 square mm. inside wall size is made possible.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the production of Teaptsu Mold O, If! The present invention relates to a method for manufacturing a large scale chipboard O.

Continuous casting molds are classified into type 11 assembly type molds and tear plastic molds, but compared to the plastic mold plate molds, there is no molten metal O inserted in the corner part, and the middle mold type There is also the advantage that the mold metal body can be made into a t-punpack.However, conventionally, the inner wall dimension of the chapetsu mold O manufactured by electrodeposition, drawing, etc. is at most 230 square meters. It is impossible to prepare O items with O dimensions above, so it is a large steel O.
Furthermore, the conventional method had the disadvantage that II construction was impossible. Since Abuts Mold uses steel or wire steel alloy for the mold body with a plate thickness of 1.0 S.Vat, when electromagnetic stirring is performed, the O magnetic field loss within the wall mold is large and a large amount of power is required. The disadvantage was that it required a load of 1kh.

So, the inventors of the present invention decided to use the conventional method. As a result of intensive research into a method of making a mold O11 that can eliminate the defects of the Ebtsu wall mold O11, we have completed the present invention by establishing a method of manufacturing an extremely purposeful Chebura wall O.

That is, the original Ip1 is.

) The mold body is made of mechanically strong material such as carbon steel or 4F special steel.
M%A material is used, and cooling water grooves are machined on it, and the copper plate with good thermal conductivity is made of steel alloy 01-S on the surface where the cooling water grooves are machined.
After making a two-layer rad O flat plate by joining an O-thick O flat plate with diffusion casting 1/a1, remove the two-layer Tatsu Y flat plate by pressing etc., and mold the fin into a chapetsu mold. Diffusion melt 11 as an O structural member! (2) The mold body is made of carbon steel, 411 special steel, or other 0 mechanical strength oIIi%fh material, and cooling water grooves are machined into it. Then, after processing with scissors and cooling water, we made a two-layer TUD flat plate by joining 1~SO-thick flat plates of copper or steel alloy with good thermal conductivity of 0 using diffusion connection, etc.
Heat-resistant, abrasion-resistant EG-special copper on the axillary layered flat plate,
After manufacturing a two-layer Tud flat plate made of Ii alloy etc. by diffusion bonding to a thickness of 11~1. , and diffusion welded this as a component of Chapra Shield 0 *Fusing 11
11. &k) This article also relates to a method for manufacturing a chip-pull-fold O, which is characterized in that it is closed by tightening or the like to form a chip-like shape.

According to the present invention) a large lid with an inner dimension of R50wm square or more,
It becomes possible to make a tea tool with good electromagnetic stirring effect.

Hereinafter, the method for making the zero-shot *Df Aptes mold O11 will be described in detail according to Nos. 1 to 41I.

As shown in 1-1, the mold body 1 is made of carbon steel.

Use a material with high mechanical strength such as steel, and process cooling water grooves 2 into it! , its cooling water groove processing IIK heat conduction wheel is made of pure copper.

As shown in (b), it is also possible to set the TKS layer to 11 [4].

If the thickness of the copper-based material SO plate is 1 mm, the temperature distribution will be uneven, and the thickness and cooling capacity will be insufficient. t', copper-based material S is 1 to S・-〇 1 to 1 when performing thick electromagnetic stirring

The illustrations above are based on the case where a single @@aS layer clad plate is used to create a Teaps peak Rudo OII, but 2
Commercial operators will be impressed by the fact that Oka II can be manufactured using a layered clad plate.

Zero-shot f14t) f Depends on the manufacturing method of the Apts mold L Conventionally, the inner wall dimensions are maximized by electrodeposition, drawing, etc.! The chip-shaped mold that could only be manufactured up to 1.2 square meters now uses a two-layer or one-layer clad plate manufactured by diffusion melting @1.

It is now possible to produce items that are larger than tia-square 0 * @ 0. With a large mold, it is possible to cast a large steel O**, and by increasing the amount of charged OII steel, it is possible to produce a large amount of raw material.

In addition, the Chepra mold manufactured by Zero Hat@) is an O″e mold that can be made thinner from copper-based materials with good thermal conductivity.
, when using electromagnetic stirring, O magnetic field loss is reduced, which is great from an energy saving perspective! '& Effective.
