なければならない。Slabs were manufactured by cutting the slabs by heating and rolling them to a reduced thickness using hot rolling equipment. The thickness of conventional continuous slab casting is 200 to 250 mfi and the width is 900 to 200 mfi.
A round slab with a diameter of 01Xlfi is manufactured and cut into lengths of t5 to 12m on a continuous casting line, and then a large number of cut pieces are heated in the heating furnace of hot rolling equipment again to hot straight arc. Temperature suitable for (approximately J 200 C for ordinary steel) 11
After heating at
The trout is rolled at about 1 t, then rolled up in a downwheel and transported to the primary process. The cumulative area of the slab sac becomes important, and the sensible heat of the slab is taken away by the atmosphere, and the temperature Iri, which was about 1200C at the cutting position, is 900C8.
! It will be inserted into the heating furnace in a state where the temperature has dropped to a certain temperature. Therefore, in the heating furnace, the slab is heated to 900C.
The steel must be heated to a temperature of 1200C to make it hot-rollable.

る従来設備について共通するものである。However, since the heat loss from heating 1 exhaust gas in the high temperature section and the furnace wall is large,
To raise the temperature to -1, a heat amount of 300,000 1 (Cat) per ton of slab is required. This drawback is common to conventional equipment that adopts the slab cutting type.

の点につ陰解決する必要がめった。In order to eliminate these conventional drawbacks, we developed a synchronous continuous rolling equipment for rolling mills that maintains the temperature of the slab at a temperature suitable for hot rolling as much as possible, and eliminates or minimizes the need for double-sided heating of the slab. However, in order to realize this, it was necessary to solve the following points.

十分である。It is necessary to have a wide range of thickness from 1 to 25 mm to meet the demand, and to obtain the strength f required for steel materials by rolling the cast structure to the rolled structure, but the rolling ratio (
Slab thickness/product thickness) is generally required to be about 5 to 7. In the case of the conventional slab thickness of 250mm, the product thickness is 2
Even in the case of 5 mm, it is possible to secure a rolling ratio of 10 or more, but the aim is to achieve a thin slab thickness of about 100 mm to 59 tn1 m.There is no problem if the product thickness is thin, but for example, in the case of a thick product of 25 mn, The rolling ratio is 4 to 25, which is insufficient.

本発明はこの様な従来の欠点と長所を生かし。The present invention takes advantage of these conventional drawbacks and advantages.

圧延機に供給するものである。The present invention minimizes heat radiation by winding the thin slab obtained by high-speed continuous casting into a coil, supplying it to the entry side of a finishing hot tandem rolling mill through a heat retention furnace, and unrolling it at a high temperature for finishing. This is done by supplying the product to a rolling mill.On the other hand, in the case of thick products, the thickness is reduced by rough rolling using conventional equipment, and then the product is supplied to a finishing mill.
以下本発明の一実施例を図面に沿って説明゛する。An embodiment of the present invention will be described below with reference to the drawings.

This is, for example, a synchronous mold that is capable of high-speed casting. In this case, the type of casting machine does not matter as long as it is possible to cast thin slabs at high speed.

The molded slab is drawn out as a slab 5 whose inside is unsolidified. Furthermore, the solidified thickness of the slab 5 at the exit side of the mold is approximately 19 mm9.
degree. Therefore, in order to achieve complete VC solidification, the slab is supported and cooled in the spray cooling zone 4. After the slab 5 is solidified and cooled almost to its internal center in this manner, the slab 5 is heated in an adiabatic furnace 6 to be uniformly heated.

It is bent by a winding roller 21 and wound into a coil shape by a winding machine 11. The coil is divided into pieces having a weight of approximately 5 to 45 tons using a running shearer 8, and after one division, the coil is wound at a high winding speed to minimize the temperature drop of the slab 9 due to heat dissipation. i
It also serves to prevent the temperature of the adiabatic furnace 10 from dropping.

ｆＪｒｎ。This is how you create a thin cast slab coil! 3 is transferred to the coil heat retention furnace 12 and stored there for 1 hour. The coil heat retention furnace 12 is equipped with a heater 1, for example, a heavy oil burner, which is used to raise the temperature inside the furnace and to keep the coil iat warm for a long time. The size of this coil heat retention furnace 12 can be set in any way depending on the specifications of the rolled film, for example, the width fJrn.

に於ける生産量の不一致やトラブルを充分吸収し得る。If the scale is about ism in length and 2 m in height, it will be possible to store about 30 normal coils, and it will be able to sufficiently absorb production volume discrepancies and troubles in continuous casting equipment and hot rolling equipment.

１台当り５〜１０万トン／月程度であるから、生産能力
のバランス上、連鋳機は２〜４台設置されるのが通常で
ある。In general, hot rolling equipment has a capacity of 200,000 to 300,000 tons/month, whereas conventional continuous slab casting equipment has a production capacity of about 50,000 to 100,000 tons/month per continuous caster. In order to balance the capacity, two to four continuous casting machines are usually installed.
これに対して薄厚スラブ高速連鋳造は５〜１０ｍｚ−の
鋳造速度が可能であるから、鋳片サイズ８０厚Ｘ１２０

ことにすり、鋳造能力の点で従来の２倍となる。On the other hand, high-speed continuous casting of thin slabs allows casting speeds of 5 to 10 mz-, so slab size 80 thickness x 120 mm is possible.
In the case of 0 mm, the production capacity is 10 to 200,000 tons/month, which is twice the casting capacity of the conventional method.

好ましい。Problems with continuous casting equipment often occur and production is halted. In addition, in line with this, it is necessary to rearrange the rolls at the hot rolling equipment once every few hours, and production is temporarily stopped. Moreover, the timing of these stops does not necessarily coincide due to their nature. For this reason, it is necessary to provide the coil heat retention furnace 12f to temporarily store the coil. It is also necessary to have a margin in the production capacity of the continuous casting equipment in order to fully utilize the capacity of the hot rolling equipment. Therefore, it is actually preferable to install a plurality of continuous casting machines as shown in the drawings showing an embodiment of the present invention.

It is continuously supplied to the machine 16, wound up into a coil again by the town coiler 17, and conveyed to the next process. As mentioned above, the product board thickness Fil~lQmn@l[ at this time is relatively thin. However, the rolling ratio is not sufficient for thick materials up to about 25 mm.

供給されるものでおる。In the conventional equipment, a slab material with a thickness of 250 m H is heated to about 1200 c in a heating furnace 19 and then transferred to a rough rolling mill 18.
The pressure is reduced to 0 to @Q m n and then supplied to the finishing tandem rolling mill 16.

It will be moved up and transported.
