230 thousand tons, established laminose base to connect even casting rolled steel of make friends product line a on manufacturing history new milepost. Product line of Bao Gang CSP connects exorbitant effect to change manufacturing technology to develop, crop was achieved 2005 288.

40 thousand tons, in technology of efficient fine, Lian Zhu, rolling and whole technological process efficient and fast rhythm produces technical system respect to sum up development to give measure of 19 main techniques and tricks of the trade, developed laminose semifinished product flawless pouring, CSp controls even make friends process rolling, control the advanced technique such as stability of performance of cooling, plate and uniformity control, highest reach even the number that irrigate furnace 28 furnace ／ to irrigate second, highest sheet casts second turnout for 4865.

2 tons of ／ are irrigated second, it is even the number that irrigate furnace on average 21.

Month of 1l furnace ／ , exercise rate is even casting machine 90 ％ , rate of rolling mill exercise is more than 80 ％ , leakage steel rate is less than O.

085 ％ , amount to integratedly into material rate 98.

0 ％ . Additional, the Csp product line of Han steel and ripples steel was produced 2005 also can achieve respectively 259.

60 thousand tons mix 2.41 million tons. 2005 the line of the FTSR that connect steel of put into production of the end of the year, only the level that a month achieved to produce per month a quantity to design productivity more than. The laminose base of the enterprise such as steel of saddle steel, Bao Gang, Tang Gang, Han connected casting to create even make friends product line sheet flows or double shed Lian Zhu the record that the month does not have leakage steel, saddle steel, Bao Gang all achieves rolling mill year the Gao Shuiping that exercise leads more than 80 ％ . Level of advanced equipment technology brings a product high grade change proof of a lot of practice, use laminose base to connect even casting make friends product line to produce thin norms and strip steel of ultrathin norms hot-rolling, more traditional and intertropical rolling mill has distinct advantage. In make friends connecting even casting to produce flow in laminose base, the laminose base temperature that raises gentle soaking through rolling bottom type furnace. Can amount to ℃ of 1100 ℃ ~1150, prep above takes the temperature of base among traditional rolling mill, and the temperature of width of laminose base edge and length direction is very even, it is rolling thin norms and the advantage with ultrathin intertropical norms, part of completely conditional implementation with tropics cold, if produce thin norms container board, pickling of hot-rolling plating zine plate, hot-rolling board and partial hot-rolling rushs greatly board etc. In last few years, domestic and international ～ some laminose base uses even casting equipment and technical dominant position even make friends product line, through be in control of molten steel composition, Lian Zhu and heat craft is optimized and a series of control technologies and step are taken in the rolling regulations of finish rolling aircrew, realized thin norms and the batch production with ultrathin intertropical norms in succession. Successful already make friends gives clue of bead steel CSP 0.

98 millimeter are thin bring a product, ply ≤ 2.

Board belt is as high as the container of hot-rolling thin norms of O millimeter 50 ％ left and right sides; Tang Gang and ripples steel already also succeeded respectively rolling goes out 0.

8 millimeter and 0.

78 millimeter are ultrathin norms strip. Using craft of the half rolling that do not have a head to produce product of ultrathin norms tropics is the one large dominant position that laminose base connects even casting make friends product line. Ripples steel is debugged in CSP line equipment and during trial production, into thousand the many half rolling that do not have a head experiments, hold to application not to have batch of head rolling technology to produce thin norms product partly, realized 269 meters chief semifinished product (segment 7) manufacturing O.

The historic breakthrough of 78 millimeter product. Line of Tang Gang FTSR undertook 30 meters go to 138 meters length even casting semifinished product 1 break up 4 break up, the thinnest norms 1.

The half rolling do not have a head of 4 millimeter experiments, gained initial success and accumulated valuable experience. CSP produces low carbon high strenth car board is out of shape research of austenite transition rule and control rolling and control cool craft organizes function to consider to make clear to armor plate, reasonable adjust rolling and cooling craft system to be able to refine armor plate microstructure significantly, improve the mechanical performance of armor plate. Bead steel and university of Beijing science and technology are developing low carbon high strength in car board process, to reduce manufacturing cost, facilitate production is organized at the same time, assure steel-making, Lian Zhu, rolling between each working procedure join each other, fill those who distribute brandish rolling mill to produce can, came true below CsP technological process low cost, efficient produce low carbon high strenth of car board flexible change manufacturing technology. Flexible below the condition that the nuclear idea of technology of rolling technology control thinks even if reachs the craft that connect casting in same smelt craft, chemical composition, according to rolling mill technological equipment ability, through changing system of refrigeration of rolling, laminar flow and reel-up craft, produce the high-powered board that gives different intensity level thereby, in order to satisfy the requirement of different user, and manufacturing rhythm and efficiency can improve on certain level. From in recent years our country laminose base connects even casting make friends to produce a technology to develop current situation analysis to see, the hot-rolling that laminose base produces even casting even roll steel board coil to be mixed at present in our country in connecting the heat that come make friends board to bring a product, all have larger proportion (about 30 ％ control) , equipment of its product line all is achieved or be close to international top-ranking level, representing our country iron and steel to produce the important facet of advanced technological process. Nearly two years, lian Zhu of a few laminose base is in even make friends enterprise efficient change production and new line to amount to produce, the respect such as the research of constituent function feature of development of engineering technology of control of process of development of new product research, rolling, steel and control obtained a batch of new positive result, among them partial gain achieves international banner level. Our country steely enterprise also should see, compare with traditional flow, laminose base Lian Zhu is in even make friends craft respect of metallurgy process mechanism has its apparent feature; Method and technology are controlled to go up in process, need is dug adequately according to flow characteristic and develop the latent capacity of flow, undertake relatively of the system, the research development of innovation sex, ability creates higher level and benefit. To this, laminose base of author proposal our country connects even casting technology of make friends equipment to develop to will notice the following henceforth: Above all, the smelt in solving laminose base to join even casting make friends course further, fine, double flow or shed Lian Zhu more, heat reach heat to join press hard against each other of each technology segment optimize join match, develop each equipment latent capacity, realize efficient stability to turn production. Next, laminose base (base of the thin plate in including) caky process control and field trash control the steel fluid in Lian Zhu process, it is to matter to the crucial link of the base that connect casting and finished product surface and in-house quality, need is done good crystallizer and irrigate affusion mouth structure to improve, the type selecting of steel current field and control of temperature field analysis, protective broken bits that plants in the light of manufacturing steel and research, combine electromagnetism apply the brake, soft pressure wait for an advanced technique, and production is flawless the premise that high quality connects casting semifinished product is plank of manufacturing high quality and condition. The 3rd, to strive for cost-effective enhance product competition ability, should take laminose base seriously to connect even casting process of make friends flow to organize function to dominate mechanism and relevant technology basic research, the research that increases new product of high-powered, high strenth, high additional cost develops strength, form seriation and stability to turn production hard. The 4th, enlarge thin norms scale and the half rolling that do not have a head is laminose to play base joins even casting dominant position of make friends flow, rise benefit and become a useful person rate, promote energy-saving fall bad news all has important sense, and how to solve real operation to control the question with big difficulty to realize stable batch production, it is the task that need solves. The 5th, while new product, new technology considers to develop, the 2 innovation sex that should notice laminose base connects even casting make friends craft to control software considers to develop, on the foundation of original craft software, should form stage by stage new, perfect, the laminose base Lian Zhu that has own intellectual property connects technology of make friends process to control software and relevant technology. The 6th, the laminose base with relatively perfect work up connects even casting make friends technology to consider to develop systematic peace station, at the same time education has the research of innovation sex one batch to develop a team, this is laminose base Lian Zhu assure what develop even make friends technology ceaselessly at all.
