Cut To Length Line

The Cut To Length Line, 2-12x2200mm cut to length line is a high-precision and easy-to-operate machine that is designed to open and process steel coils into accurate and flat sheets of steel. This machine is equipped with a PLC control system that ensures precise cutting, leveling, and rolling of the steel sheets.
The purpose of the Cut To Length Line is to convert steel coils into flat and accurate steel sheets. This machine can handle a variety of coil widths (2-12mm) and lengths (up to 2200mm), making it a versatile solution for different kinds of steel processing needs. Once the coils are loaded onto the machine, they are automatically fed into the opening and cutting system that removes a portion of the coil and flattens it. The leveled steel sheet is then passed through a precision leveling system that ensures the edges and surface of the sheet are completely flat and uniform. Finally, the cut-to-length sheet is rolled into a coil and ready for use.
The Cut To Length Line is designed to provide a high level of automation and ease of use. The PLC control system enables the operator to set the cutting and flattening parameters so that the machine can operate with high precision and efficiency. The machine is also equipped with sensors that detect any deviation from the set parameters and automatically adjust the cutting and leveling process to ensure that all steel sheets are produced with the same high level of accuracy.
 

The Cut to Length Line is mainly used to uncoil the raw strip steel coils, and collect the steel plates with fixed length after initial leveling, cross cutting and fine leveling. The unit adopts PLC control, high precision and convenient operation.

7. Working system and production capacity calculation

For three shifts continuous work system, holidays do not rest. The annual effective working time is 6,500 hours, once a year for major (middle) repair, 20 days each time, one shift per week for minor equipment repair, 20 minutes for shift shift, to check equipment, production handover and cleaning site. The annual working time is determined as follows:

(1) calendar time: 8,760 hours/year

(2) annual maintenance time

Days per year 20 days per year

Hours per year 480 hours per year

(3) weekly light hours

Weekly sessions 1 time

Hours per week 8 h/week

Hours per year (528) 416 hours per year

(4) shift time

The shift time is 20 minutes per shift

Hours per year: 345 hours per year

The above non-production time subtotal is 1,241 hours/year

(5) set working hours

Hours per year subtotal 7,500 hours/year

(6) tool change and other downtime

Hours per year 3,000 hours per year

(7) years of effective working time 4,500 hours per year

Production capacity calculation:

(1) calculate the length of the steel belt

The weight of the 10mm thick 1700mm wide steel strip per meter is 0.133 tons, and the length of the 30-ton steel coil is about 220m

(2) calculate the shear time

According to the average speed of the unit 6m/min, it takes 38 minutes to cut a 30-ton steel coil, 23 minutes to unroll, load and unpack, and cut a 30-ton steel strip in one hour. It works 4,500 hours a year, and can cut about 4,500 rolls of 30-ton steel belts, totaling ~ 130,000 tons.
