In a typical production facility using cold rolled steel coils, the downtime for roll conversion can be large.In fact, coil switching and re-threading can result in a loss of productivity of between 20 and 30%.Therefore, before processing, it is worth inserting a machine into the production line, connecting the end of the steel with the beginning of the steel in the next coil in one coil.If the end of each coil is welded to the beginning of the next coil, then without increasing the production speed, the productivity will be maximized and the risk associated with faster production speed will be borne.There are two basic ways to connect the coil to establish the coil line, ready-Weld and flash-butt welders.Prep-Joint-fitting welders use connection processes suitable for several coatings and non-coatingscoated steel.It involves cutting a part of both ends off two pieces of steel, then slightly overlapping before welding the two ends together, and then leveling the final connection.A disadvantage of preview --Lap welding means that the thickness of the weld may be different from that of the raw material.Flash-Butt welding is a good way to connect coils.The end of each belt is set to a copper clip.The current passes through the fixture, pressing the strip together to complete the welding.One drawback is flash build-Up, must fall down.Flash-Cost of butt welding-High welding integrity.If TIG welding machine is used, the Arc will extend from the electrode to the place where the electrode is connected, melting the material.The arc itself is protected by inert gas, and the ends of the two lines are melted and then set immediately.Coil joints with TIG welding can be used to weld non-ferrous materials, copper, brass, aluminum, galvanized stainless steel, pre-Painted steel and soft steel.As long as the carbon content is lowCarbon steel, hardness-Upward should not be a problem when connecting the end of the coil.For most metals, the welding cycle takes about two minutes.In production facilities including Coil Manufacturing-Up welding machine, also often add coil accumulator, so that there is enough steel to keep the production line running when the two coils are connected together.If you have a TIG welder that takes two minutes to connect one coil to another, then you need an accumulator that holds steel for at least two minutes.Consider using only Open co as a stamping facility to access the equipment.When reaching the end of the coil, someone has to stop the production line when a new coil is in place and threaded into the machine.The typical operating speed of the stamping production line is 40 feet kilometers per minute.The average down time for changing coils for stamping equipment is about 10 minutes.Steel stamping equipment will process 5 to 10 coils per day on average.The heavier the specification of the steel, the more coils are used.If you know the profit per foot and assume that the factory is running 250 days a year, you can easily calculate how much profit is lost due to coil conversion.For steel stamping equipment, assume a profit of $0 per foot.05.X $0 40 feet/minute05/foot = $2.Profit in 00 minutes, or $120.00 per hour.If you process 5 coils per day to 10 coils per day, the profit can be doubled without having to speed up the processing equipment.A coil build-Queuing and bringing accumulators is a smart investment that will soon pay for the profits it has added.
