ABSTRACT:
The present invention is directed to a rough rolling mill for rolling a slab of material into a rough bar through a hot rolling process. The rolling mill reduces material temperature drop thereby preventing a decrease in productivity. The rolling mill train for producing a rough bar from a slab of material has at least two close mill couples at an outlet side thereof. Each close mill couple is composed of two rolling mills arranged in tandem close to one another to roll the material. The at least two close mill couples are arranged so that the material being rolled is not acted upon by adjacent close mill couples at the same time.
