Q:Measures to prevent cold rolling of packaged cold rolled steel coils? Who can give some professional opinions oh?
In order to prevent rusting in the process of storage or transportation of steel roll, steel mills generally take the following packing: inner gas antirust paper wrapped with tape wrapped in plastic film sealing, intermediate, involute cardboard seal lining, cardboard corner, with iron and steel outer package corner protector, strapping fixed. If the inner package seal, so the steel coil is sank into the water, will not rust out.
Q:What are the characteristics of hot-rolled steel coils and cold rolled steel coils? What loading and unloading tools should be used? What items should be paid attention to?
General handling steel rolls are used for driving. Forklift trucks are OK, but a larger fork truck, usually cold rolled, weighs less than 15T. The hot rolled coil is below 30T.
Q:In the warehouse management system of steel coil
The warehouse is set to be required under the factories and production equipment and manpower planning, reasonable layout; to strengthen the internal economic responsibility system, scientific division, forming material export management assurance system; the service must implement the work quality standard > standardization, application of modern management technology and the ABC classification method, and constantly improve the level of warehouse management.
Q:What brand steel tapes are of good quality?
Durable durable depends on your personal use frequency, the high frequency nature is easy to wear, resulting in scale. If you like fuzzy units if buying tape need verification it is best to buy the Great Wall Seiko goods, because the time to measure the number of verification inspection of steel tape, basically qualified rate of the Great Wall Seiko steel tape can reach one hundred percent.
Q:On how to reinforce steel coils in a container
In the bottom and sides with a thick strip stuck, but also to ensure that the wood will not loosen down...... Rough steel rolls, I saw people loading and unloading on the docks, poked them directly with a small forklift truck, and then reinforced with wooden planks
Q:The difference between aluminized color steel roll and ordinary color steel roll
Ordinary color steel roll is a composite material, also known as color coated steel plate, is used in the continuous production line on the production line after surface degreasing, phosphating and other chemical coating treatment, painted with organic coatings, made by baking products. Both steel and organic materials are a little bit different. Both the mechanical strength of steel plate and easy molding performance, but also organic materials, good decoration, corrosion resistance.
Q:Several reading methods of steel tape measure
Indirect reading methodIn some parts of the steel tape can not be used directly, can use the ruler or ruler, the zero alignment measurement, ruler and measurement direction; steel tape measure distance to a whole scale ruler or ruler, with more than a long reading amount. (3).Some errors in measuring steel tape
Q:What is the accuracy of steel tape inspection
This is the smallest scale brothers precision measuring tools, minimum scale steel tape is mm, mm is estimated to read out the data, such as steel tape measure length is 12.5 mm, which is 12 in the steel tape on the scale with the number of 0.5.It was read out. So the accuracy is millimeters.
Q:What is the difference between a steel strip and a coil? The steel strip is flat steel, and the steel coil is made of steel.
Steel rolls are also called steel belts. There is no difference between them. They are not flat steel
Q:What's the length of a coil of cold rolled steel? Is there a standard?
But in the process of production, not the large volume, a few kilometers long have. The small volume sold by the finished product is much shorter.
