30TON/HR ROLLING MILL PROJECT

I. GENERAL 1.1 PREFACE This offer sheet covers the supply of the equipment and materials for a Bar Mill Project capable of producing 200,000 tones per year of Deformed Bar with product size of D10, D12, D16, D19, D22, D25&D32. and Rung Bar with product size of ∮9.5mm～∮32mm

1.2 Plant description The main features of the rolling process and equipment composing the Plant are described in the following article. The layout and Mill capacity of the Plant is shown in the attached ”General layout and calculation plan”

1.3 General features of the rolling Mill Process This rolling mill is provided with necessary equipments for rolling of bars. Capacity of the rolling mill is 200,000tons/y. Production ratio of the different bar sizes can be selected freely, according to distinct market demands. 40tons/hr, top fired, Pusher type Reheating Furnace, energy saving technology and easy operation procedure are applied Arrangement of mill stands is all tandem Horizontal type mill. The Roughing Rolling Mill is driven by AC 1,500HP motors, and Intermediate Mill is driven by AC 1,500HP motors, but the Finishing Rolling Mill are driven by DC 1,200HP motors with Control SYS. Total capacity of AC&DC motors is 3,100kw. Low tension rolling is applied by Loop Control System in the Finishing mill depending on the size of the products.

II. DESIGN BASIS 2.1 Product Mix and Rolling Rate 2.1.1 Product Mix Product mix for annual production of 200,000 tons is described as the table “Calculation Plan of Mill Capacity”. 2.1.2 Rolling Rate With regard to rolling rate, please also refer to the table “Calculation Plan of Mill Capacity”. 2.1.3 Others Product length of bars: 12M or others

2.2 Billet Billet: Continuously cast billets or hot rolled billets Kind of steel: Low alloy steel for the manufacture of steel bars for reinforcement, rolled steel for general structure. Section Length Weight

100～130 mm sq 4m ± 10 mm 314～450kg

Camber (bow): Max.25mm in 4000mm length Rhomboidity (right angularity): Less than 3% Twist: Less than 1 degree per meter Temperature of billet discharged: 1100℃ (Engineering basis) Note: The billet above shall have the quality suitable for final products. In order to attain high productivity, that is, improvement of rolling efficiency and material yield, etc. which are resulted from high rolling Rate and most suitable cutting of bar products , etc., it should be essential to well control the billet tolerance and conditions.

30TON/HR ROLLING MILL PROJECT

2.3 Rolling Capacity 2.3.1 Rolling Hours Required Rolling Hours Requires=5760 Hrs/Year With regard to rolling hours required, please refer to the table to “Calculation Plan of Mill Capacity”. 2.3.2 Annual Working Hours 8 hours/shift×3 shift/day×300 day/year=7200Hr If operating rate is 80% Operating Rate 0.8=Rolling hour required/Annual working hour Rolling hour required=0.8×7200=5760Hr This operating ratio is considered to be easily attained.

2.4 Steel Grades The steel grades which are to be processed on the mill are as follows. a. Deformed bar D10~D32 Steel bars Applicable standards: JIS 20-2525＆24-2536 “Rolled steel for general structure” b. Rung bar ∮9.5mm～∮32mm Steel bars JIS G 3101&JIS G4051 2.5 Rolling Speed Actual rolling speed: Max. 11 m/sec

2.6 Rolling Method 1. strand rolling Deformed bars: D10, D12, D15, D20, D22, D25 &D32mm Rung bars : ∮10, ∮12, ∮16, ∮ 20, ∮25 &∮32mm

30TON/HR ROLLING MILL PROJECT

2.7 Site (Environmental) Conditions 1) Ambient temperature: Max. 35 deg. C (more than 15℃) Electrical control room and pulpits will be kept in 20~30℃ 2) Relative humidity: Max. 98% 3) Altitude: Less than 1,000 m above sea level 2.8 Layout Please refer to attached GENERAL LAYOUT. 1) Rolling Mill The billet is charged on the Billet Charging Bed by the Billet Yard Crane, and transferred to the Reheating Furnace by the Billet Charging Roller Table. And the heated billets are discharged from Reheating Furnace and processed through Roughing Mill Train, Intermediate Train, Finishing Mill Train. The Cant Rolling Mill comprises a total of 11 stands(17 pass), divide in roughing mill with 2 stands (8 pass), intermediate mill with 5 stands (5 pass), finishing mill with 4 stands (4 pass). The Roughing Rolling Mill and Intermediate is driven by AC motors, but the Finishing Rolling Mill are driven by DC motors with vector inverter. All stands are arranged in horizontal arrangement. 2) Cooling bed On the Cooling Bed, products are cooled down to desired temperature, while maintaining the straightness. 3) Cutting & Finishing System a. For Deformed bar Those products are then discharged from the Cooling Bed and further processed by Cutting and Finishing System. All products are cut to length by cold shear transferred to receiving conveyor. At the end of the conveyor, a conveyed table is located which transfer the products to AUTO bundling area then to shipping area. 2.9 Utilities Conditions -6-
