Q:What is the hardness of cold rolled steel strip?
The thickness of cold rolled strip and sheet is 0.1 ~ 3mm, and the width is from 100 to 2000mm. The products are made of hot rolled strip or steel plate and rolled in cold rolling mill at room temperature.
Q:What are the sectors in which galvanized steel strips can be used?
Steel sheet galvanized steel strip is a kind of narrow and long steel plate produced by various steel rolling mills in order to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. Strip steel, also called steel belt, is slightly different in length according to the size of each roll. The strip is supplied in general, and has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving.
Q:What are the categories of strip steel? How do you distinguish it?
Steel is divided into two major categories: carbon steel (carbon steel) and alloy steel by chemical composition. Carbon steel is an alloy obtained by smelting pig iron. Besides iron and carbon, it also contains a small amount of impurities such as manganese, silicon, sulfur and phosphorus. Carbon steel has a certain mechanical properties, but also has good technical performance, and low prices. Therefore, carbon steels have been widely used. But with the rapid development of modern industry and science and technology, the performance of carbon steel has not fully meet the needs, so people have developed a variety of alloy steel. Alloy steel is a multicomponent alloy obtained by adding certain elements (called alloy elements) on the basis of carbon steel. Compared with carbon steel, the properties of alloy steel have been improved greatly, so it has been widely used.
Q:What is the difference between galvanized steel cold base galvanized steel strip and hot galvanized steel strip?
The soaking process is mainly used in electroplating process, some appearance of repairing damaged more, a large number of plates or on the hot dip galvanizing process implementation. Cold is the use of zinc plating on the surface of the steel plate with filler replacement attached to a layer of zinc to the surface of the steel plate, the plating thickness is very small, generally between 10-50g/ square meters, anti-corrosion performance is poor, and its effect and general coating, sometimes as coated with a layer of anti rust oil in key parts this method should not be used so as not to affect the structure and properties of corrosion. The above is hot dip galvanized plate is heated to 500 DEG C into liquid zinc (zinc liquid temperature about 470 degrees Celsius), the formation of Zn Fe alloy coating and zinc layer, this method is the most commonly used, and the thickness of zinc can be controlled in more than 20 mu, ranging from 60g-275g/ square meters, even more thick, far better than cold plating process.
Q:What is the cause of the deviation of the strip in the rolling process? How to deal with it?
Operation reason, because the operator double pendulum adjustment is unreasonable, causes the strip deviation.
Q:What's the difference between hot rolled strip and cold rolled strip? What's the difference between hot rolled coil and cold rolled coil?
Hot rolled coil is above the recrystallization temperature of rolling, cold-rolled plate refers to the recrystallization temperature following rolling, popular point that is in the hot strip rolling red hot state, while cold rolled hot-rolled is under normal temperature rolling. Hot plate often said refers to the hot rolled plate, cold plate refers to the cold rolled plate, hot rolled, cold rolled and hot rolled coil is said and cold rolled coil.
Q:65 what is the hardness of the best heat treatment of manganese steel strip?
65, the optimum heat treatment hardness of manganese strip depends on the application and heat treatment method;1, 65Mn strip at 850 degrees Celsius, quenching oil +180 degrees, low temperature tempering 6 hours, hardness can reach HRC56 or so.2, if it is 400 degrees Celsius, tempering 4 hours, its hardness is generally around HRC39.
Q:What is the difference between steel strip and strip steel?
The steel strip is the product which the processing enterprise cuts the strip steel according to the specific machine size to cut into a certain length, the width, generally assumes the enclosed circle shape. For example, steel conveyor belts, such as furniture or wood processing enterprises, "band saw" saw blade, but also steel band.
Q:Causes of zinc removal in hot rolled strip
The residual impurity particles on the substrate surface are not removed before immersion into the zinc pot, which affects the adhesion of the zinc layer.
Q:What's the cutting edge of cold rolling strip?
Cold rolled materials are generally cut edges. The hot rolled material is partly rough. Cutting edges and burrs can be viewed straight. The two sides of a strip of steel, similar to those of waves. The two sides of the trimming are straight.
