To achieve these goals, the utility model is that the front portion on support is equipped with motor, main-gear box and two vertical frames of axially-aligned successively, on these two vertical frames, be equipped with horizontal topping roll and horizontal bottom roll respectively, be connected with power transmission shaft respectively between two horizontal topping rolls and two horizontal bottom rolls, horizontal topping roll on one of them frame is connected with the main-gear box that is connected with motor by the power transmission shaft that is connected respectively again with horizontal bottom roll, constitutes two horizontal roller blooming mills; Be equipped with two the horizontal type frames transversely arranged respectively with this two frame at two vertical frames rear portions, be equipped with two rolls that stand respectively on these two horizontal type frames, per two rolls that stand are connected with the main-gear box that is connected with motor by the power transmission shaft that connects respectively, constitute two roller finishing mills that stand.

Effect that the utlity model has and outstanding characteristics are:

The utility model can and actinobacillus device, take-up and Control System of Microcomputer etc. are formed a cover high speed cold rolled rib steel bar tandem rolling automatic production line, realized the high speed cold tandem rolling, broken through the low speed cold rolling technology, the cold-rolling process equipment and the technology that have replaced traditional backwardness, than the high 3-6 of traditional cold mill milling speed doubly, mill speed is the 9-13 meter per second, the high 4-5 of single machine yield doubly, can reach 36000 tons/year, not only economic benefit increases substantially, also can satisfy the fixed point engineering and the heavy construction standardization of product-quality indicators, seriation, large batch of needs promote the formation and development of the industrialization of cold rolling high performance steel.

2. equipment manufacturing cost is low, and a cover unit annual production reaches 36000 tons, is equivalent to the 3-4 cover of cold-drawn milling train and traditional cold tandem mill, and cost only is 450,000 a yuan/cover.

3. adopt the poor and AC frequency conversion speed difference in planishing roll roller footpath just, realize that heap draws the rate fine setting, fine adjustment speed is 1/50 second, trimming precision resolution ratio is in ± 0.2mm, accurately realize the 9-13 meter per second high speed cold tandem rolling that the second flow amount equates, product mechanical performance technical indicator is all above Chinese GB-13788-92 " cold rolled reinforcing steel bar with ribs " national standard and ISO international standard.

4. can rolling cold rolled reinforcing steel bar with ribs wire rod, again can rolling scale vertical bar, can roll mild steel, medium carbon steel, low-alloy steel and high-carbon steel cold rolled reinforcing steel bar with ribs series of products, two rib cold rolled reinforcing steel bar with ribs of rolling many steel grades of Φ 4-Φ 16mm different size, product can normalization, seriation, high standardization.

5. be equipped with computer realization automation control operation, from getting the raw materials ready, fine away, clear steel, the automatic de-scaling of level and vertical interlaced, to the mother metal sizing, the high speed feeding, the high speed guide and guard, High Straightening Speed and turned off in synchronization, the high speed spiral, rewindings etc. have all realized automation, being furnished with the fluorescent screen numeral shows, in the working at high speed process, be provided with rolled piece running induction flasher, in the sealing operation of rolling, can observe rolled piece working at high speed state intuitively, complete rolling equipment modern design, make the people feel lucid and lively, daring, peculiar, be the rolling equipment technology of new generation that embodies contemporary new and high technology, can satisfy the needs of the steel rolling technology progress of sustainable development.

Below in conjunction with accompanying drawing and with embodiment the utility model is done to describe in detail

Fig. 1: front view of the present utility model
