Description

The present invention relates, according to the preamble of claim 1, to a continuous casting and hot rolling plant for the parallel production of different Rods or wires (see e.g. EP-A 0 876 225).

OLDER TECHNOLOGY

Various are in accordance with the current state of the art Production methods for continuous casting and that Hot rolling is known, the most common method being the Casting and the flow rolling of billets affects that after and after being rolled thinner until the bar or the Metal wire has the desired final cross section.

With small cross-sections, it goes without saying that machining becomes more expensive, both due to working hours as well because of the complexity. To guarantee productivity must constantly and continuously continuously increased, the value of 30 m / sec. with straight bars or 100 m / sec. with coiled metal wire is exceeded by far.

The increase in speed has limits that are not easy to overcome; so if the maximum limit is almost reached, is a significant further increase no longer achievable unless an unreasonable one Increase in production and maintenance costs.

Experiments in this direction have been made for the parallel rolling process, developed from the continuous casting of billets.

The parallel rolling process has been proposed despite the numerous Solutions fail and because of its complexity was hardly used.

The need to intervene on a line, for example because of jamming, the rolling on the second line practically impossible or at least very much difficult.

Currently, billets (not continuous casting) are used the split rolling process applied.

This solution consists in the production of two bars from a previous processing and in the rolling of the Billets for the production of rolling stock with increasing smaller cross section and thinner shape for the purpose of Separation of the rolled material fed in two bars, that rotated by 90 ° and on to the final strength is rolled (JP-A-60-130401).

It is also possible to have four steel bars followed by two Splits simultaneously on the same rolling pad, from starting with the same stick.

This process starts with a stick (e.g. 160 x 160 mm) from an oven with an hourly production of, for example, 37 tons / h.

The rolling speed (3 m / min. - 0.05 m / sec.) Is from does not support the rolling stands and causes damage and failures in the rolling means, not least due to the overheating of the rollers.

In addition, starting from a 160 x 160 billet mm for the production of a round steel of 8.5 mm diameter about 18 roll stands necessary.

In order to be productive, the speed of the in must first billet incoming billet about three times be higher than the casting speed.

Another disadvantage of the currently high speed is the increase in waste due to scooping on both ends of each rod made.

An object of the invention is to metal bars or - wires in the same amount by hot rolling, but at a lower rolling speed, also with a Cross section <5.5 mm, on reliable and inexpensive to produce wisely.

DE-4009861A (SMS) relates to a rolling mill for Manufacture of steel bars, one directly from a system with more than one continuous casting line.

From US - A - 5 404 931 is a plant for the production of strips, rods and wires known. Two are arranged in parallel on a turntable, open at the top, pouring grooves or troughs fed the liquid metal. After this the two semi-finished parts produced in parallel have cooled outside, they are made led out of the casting grooves or troughs and a parallel rolling or Hot rolling process subjected. At the end of the processing line, the finished, i.e. Endless strips, rods or wires rolled to size Coil wound or cut into lengths.

The publications and summaries of Japanese patents JP 57193205 (21.11.82), Volume 7, No. 44 (M-95), February 22, 93 and JP 57193205 refer to a rolling mill of a large, continuously shaped flat bar to produce a variety of rectangular cross sections that are diagonal arranged and in a thin line at the opposite angles are interconnected. This is done in the longitudinal direction by the calibration rolling means for the successive production of rods (not in the flow process the continuous casting line).

This flat bar is a primary rolling in a prescribed intermediate thickness with which an intermediate semi-finished product is produced. To at a different time and on a different processing line, this will be Intermediate semi-finished product heated, provided with longitudinal grooves with the help of pre-rolling agents and then split and cut into separate rectangular bars.

These rectangular bars are successively subjected to a further finishing rolling process subjected to the manufacture of the final product.

This solution is a discontinuous solution for forming a material by means of a large number of separate processing lines, it being a Continuous casting and hot flow rolling mill deals.

The discontinuous solution described above can solve the problems presented so don't solve it.

In document EP-A-0876225 called S.I.M.A.C. Spa. (a society the current applicant) will choose a method and corresponding Hot rolling plant for the flow production of bars or wires set out.

This discovery describes a hot rolling mill for flow production of rods or wires, in which the from a rectangular cross section resulting from a continuous casting by rolling and cutting into said bars or Wires are formed.

This solution sees a means with mill stands for the purpose Forming of a rectangular, emerging from the continuous casting flat cross section in a multiple sausage mold and then separating them into a plurality of separate ones Strips in the form of bars or wires for feeding into a rolling mill.

It also pre-rolls the continuous cast material unilaterally aligned before slitting into strips Longitudinal fibers in the advanced material, which of which Affect uniformity.

This lack of uniformity in the structure of the rolled Material can reduce its strength.
