Q:What is the cause of the deviation of the strip in the rolling process? How to deal with it?
Strip edge control device, fault, deviation device, tube or mirror surface pollution or other objects covered, so that the deviation of the device failure, resulting in the first line of deviation
Q:Reasons for black side of hot strip galvanizing
The content of zinc chloride in plating bath is too low, which leads to some parts can not be plated and lead to local blackening.
Q:What is the difference between strip and coil?
The coil is a thin steel sheet with a thickness of not more than 6 mm, usually less than 3 millimeters, but is rolled with a large mill due to its wide width. The width of the rolled strip is no more than 0.2 meters; the mill used is small, of course, the same thickness of the same material, the price of the coil is also more expensive than strip.
Q:What's the reason for the strip after pickling?
I suggest you try phosphoric acid and BW-500P phosphoric acid fast acid cleaning lotion, pickling process. Without heating, rust will soon. And renewable recycling. The cost is much lower than that of hydrochloric acid.
Q:What is galvanized steel strip? What's the difference between galvanized strip and cold rolled strip?
The difference between the two is that one zinc plating, one without plating, the other with zinc, is more resistant to oxidation and corrosion
Q:Specification and use of cold rolled strip
Advantages of cold rolled strip:A very thin strip of steel (0.001mm), which is difficult to obtain by hot rolling method, can be obtained;It can make the product have high mechanical properties and wide range of performance;Guarantee to obtain the high precision size, the thickness deviation is small, along the strip width and the length aspect uniformity, the shape is good, the surface is bright and clean each kind of strip steel;Low cost and high efficiency;Rolling speed, with high productivity.Technological characteristics of cold rolled strip:When the strip is rolled in cold condition, because of the hardening of the strip, the intermediate annealing must be done to soften it and restore the plasticity so as to continue rolling;The surface iron oxide scales must be removed before rolling, thus ensuring the surface smoothness of the strip and reducing the wear of the roll;Adopting tension rolling to ensure good strip shape of strip, controlling the deviation of strip thickness and reducing rolling pressure, which is beneficial to rolling thin specification products.Using process cooling and lubrication, it is easy to control the temperature of roller and strip, reduce the friction between roll and strip, and reduce the rolling pressure. It is favorable to shape control and prevent the sticking roll of strip steel.
Q:Is the coil strip? Is hot rolled coil and hot rolled strip the same?
We found differences between strip and hot rolled strip width is below 1000mm, so it can be distinguished by the Ruifeng strip and Wuhan specifications eye coil, as to why some people use a strip coil, it depends on their factory mill can tie what width, this demand is also different.
Q:What is the hardness of cold rolled steel strip?
Generally, the Rockwell hardness of annealed carbon steel is 55+-3, and the hardness of annealed cold rolled strip is above 80
Q:What are the sectors in which galvanized steel strips can be used?
Galvanized steel strip is no exception. The production process of wire and cable is also improving, the quality of continuous progress, and give full play to the unique characteristics of galvanized steel strip. Considering that the cable is often subjected to radial external force during use, a galvanized steel pin mounting layer is added outside the cable shielding layer (between the shielding layer and the steel pin mounting layer). Galvanized steel is mainly used as the radial mechanical cable protection layer, at the same time, it also plays additional total shielding effect, especially steel tape and copper wire, copper tape shielding, adopts two different shielding materials, play a complementary role in electromagnetic shielding, shielding effect will be better. From this we can see that the quality of galvanized steel strip industry is continuously improving, and the application is also developing in a broad and meticulous way.
Q:Hot rolled strip and hot rolled strip are also sealing plates? What's their function?
Secondly, strip and steel strip should be about the same, no less than a narrow strip of steel bar, the equipment configuration is the same
