Abstract

PURPOSE:To cast arbitrary ingots freely by constituting supporting roll devices for a continuous casting device freely supportably of arbitrary ingots such as slabs, blooms and billets in addition to beam blanks and constituting molds freely exchangeably. CONSTITUTION:Supporting roll devices are constituted of supporting rolls 3 for side faces of flanges, supporting rolls 4 for webs, supporting rolls 5 for the tips of flanges and supporting rolls 6 for flanges. In the case of forming a beam blank ingot 1, the beam blank is formed with 8-faces roll supporting devices (a) in a zoneI, 4-faces roll supporting devices (b) in a zone II, and 2-faces roll supporting devices (c) in a zone III. In the stage of casting a slab, a mold 2 is changed to a slab casting mold, and the respective rolls of the roll supporting devices are operated vertically. In the zonesI, II, the supporting rolls 4 for webs are operated upon an ingot 200 and in the zone III, the supporting rolls 6 for flanges are operated, whereby the slab is formed. Blooms and billets are formed in the same way.

Description

[Detailed Description of the Invention] This is related to Fuben Otsuzuki and Mashiro Continuous Tetsuzuki Tatsunao C.

Non-inventive (D) The purpose is to provide an opportunity to print a beam blank, as well as slabs, blooms, billets, etc., as needed.
What is special about my company is that it has a low exchange rate and can be made with 1 or 6 pieces of Cυ in 4' board number. The most economical production plan is Fil'j"7. The purpose is to provide a suitable display.

Since t<r, the luck of the slab is 'r'Je +@J. Therefore, if beam blanks and, for example, slabs could be made arbitrarily using one continuous exaggeration device, the demand (first egg) could be produced and the economic effect would be high. As a result of my research on σ1, I created an uninvented device.

Δ〈The gist of the invention is as follows. A steel continuous breast reed device (2) consisting of a supporting roll table (1t) following the mold, and a butaroll surface mounting frame blank (2 sides, the back surface of the slab, bloom, and block, etc.) By configuring the two-sided supporting structure T / , , ), and configuring the separate molds for each one in an alternating pattern, the frame rank (two-sided support, slab, bloom billet, etc.) can be used. It is a continuous steel shaving device that is characterized by the fact that Yu Katawozaki has made it flexible.

Now, in addition to the frame blank (Niga 1), it is also possible to use slabs or blues.
As a surface for casting any combination of aluminum, billet, etc., it can be quickly and easily converted.

Since the roller is in contact with the slab, in that case it is also referred to as a support roll device.

Next, of the support roll device, the zone indicated by the mountain is the part where the 8-curve roll holding device (shown in Figure 2 (aJ)) is placed.
The zone indicated by (■) is the part where the 1st brother of the 4-sided roll holding device ((bJ or (C) (indicated by 2) of the 2nd section) is placed.
(1111 is a two-sided roll holding device (the part shown in Figure 2) has been rewritten. 7 shows a 4J tube for cold cast slabs.

In this way, the beam blank slab 1 is cast according to a certain radius of curvature, straightened to true 1 by the letter pending rolls (2) contained in the surface of the zone (4), and then cut by a gas cutting device (not shown). The slab is then made into a slab with a fixed size of 1㎜T, and the next process, for example, is a heating furnace or a silence furnace, is completed, and then a finishing pressing process (two sides are completed).

In addition, (2n + JZ self-da? roll:) In support i7h', each roll can be composed of 1 yt, u segments, either alone or in groups of 1 core, as in the well-known device. Work becomes easier.

The moving screw 14 is connected to a driving worm m12 which is driven by an actuating device (not shown), and a worm type power transmission unit 16 (which is connected to a two-contact motor). It is activated by two.

In this way, the web support roll 4 can contact and press the web regardless of the web thickness.

It has a water circulation line 17 to prevent water from falling. Fig. 7 (shown in bJ) In the 2ff machine for beam blank casting with a low web height, the web butter roll 4.4 is shortened, resulting in a wide slab. However, in the process shown in FIG. 4, in the case of one piece 1 with a high web height, it becomes extremely easy to form a wide slab.

By doing so, each slab (two contact points) to be supported and guided becomes available, and slab castings of different shapes can be freely changed.

Therefore, all of the roles can be set up so that they can move forward or backward or move freely.
Doing I' will increase the equipment cost and require 64ff for the front mounting, so for example, both the beam blank and the slab (7mm cast)
In the equipment that carries the beam blank, the web support roll/main roll of the beam blank can be designed to move forward and backward.
