Q:Where is the good quality of galvanized steel strip?
The strip is supplied in general, and has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. Same as steel plate, strip steel is divided into two kinds of ordinary strip steel and high quality strip steel according to the material used, and two kinds of hot-rolled strip steel and cold rolled strip steel according to processing method.
Q:Where is the lining board made of polyurethane lining? Please contact immediately
Selection of raw materials: different polyol raw materials with different molecular structures and molecular weight, the performance gap between different polyols, the use of the environment and the requirements are not the same, each with unique characteristics and optimum application. Polyester polyol, wear resistance, corrosion resistance, good oil resistance, high mechanical strength, good aging resistance. Polyether polyols have good resilience and low temperature compliance, and they also have good hydrolytic stability and mildew resistance. There are many curing agents, and different formulation systems use different performance requirements. The choice of different systems depends not only on the performance requirements of the product, but also on the price of the product. The abrasion resistance of the wear-resistant lining plate is determined by the raw material chosen.
Q:What's the meaning of "double light" in strip cold rolling?
Double light: This is generally cold rolled roll of the statement, cold-rolled grades SPCC, SPCC is generally a general term, including SPCC-SB, SPCC-SDSPCC-SD is a single light, it is now generally rough surface is the material directly labeled SPCC, remove the suffixSPCC-SB is double light, the surface is mirror surface, also called bright surface
Q:What's the reason for the strip after pickling?
Pickling is only surface rust removal, which will not affect the hardness of the material.
Q:The relation between hot rolled strip and cold rolled coil, hot rolled strip and cold rolled strip
The hot rolled coil is made of slab (mainly continuous billet), and is made of roughing mill and finishing mill after heating. The hot strip from the last mill at the end of the finishing mill is cooled by laminar flow to the set temperature. The coiler is rolled into a coil and the cooled strip is rolled.
Q:What are the advantages of cold rolling and cold rolling strip steel?
Cold: hot rolled steel coil as raw material by pickling descaling after cold rolling, the finished rolling hard volumes, due to continuous deformation caused by cold hardening the volume rolling hard strength, hardness, toughness index rise decline, so the stamping performance will deteriorate, only for a simple deformation of parts.
Q:What is the difference between strip steel and silicon steel?
Silicon steel is a silicon iron alloy with silicon content of about 3%~5% and other major iron. Divided into oriented silicon steel and non oriented silicon steel, it is an important soft magnetic alloy in electric power, electronics and military industry. Silicon steel refers to a low carbon silicon iron alloy with silicon content ranging from 0.5% to 4.5%. It is divided into non oriented silicon steel and oriented silicon steel because of its different structures and uses. Silicon steel is mainly used as the core of various motors, generators, compressors, motors and transformers. It is an indispensable raw material for electric power, household appliances and other industries.
Q:What are the characteristics of cold rolled strip technology?
Cold rolled blank because the surface covered with oxide film and a small amount of impurities, will directly affect the precision of rolling and the quality of the product, so the blank material must first sent to the shallow groove company push-pull continuous pickling, pickling of oxide film and annealing to remove impurities, can be sent to the high precision six roller reversible rolling mill made the required thickness. After rolling through forced circulation cover type bright annealing furnace and high precision leveling unit two Kun to soften and smooth surface, and then finished packing or according to customer demand straight points, finally packaging factory.
Q:Is there any difference between galvanized steel strip and galvanized sheet?
Galvanized steel strip, in narrow sense, refers to strips of steel.
Q:What is the difference between steel strip and coil?
What do you think of rolling mills, not money ah, rolling strip is a small rolling opportunities, can be cheaper than rolling coil, and this cost should be spread to each product above, there are other what, like the cost of sharing ah.
