Structure of Hot Rolled Steel Strip Description


HR/Hot Rolled Steel Strip/Band

Hot rolled stieel is a semifinished product obtained from the hot rolling of slabs or billets and is produced for conversion by cold rolling. Cold rolled steel is manufactured from hot rolled, annealed and pickled strip by cold rolling on polished rolls. Depending on the thickness desired, the cold rolling requires various numbers of passes through the mill to effect the necessary reduction and to secure the desired surface characteristics and mechanical properties.

For machinery manufacturing, container manufacturing, automobile, shipbuilding

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?
The term "steel coil" is strip steel whose width is greater than 600mm and its width is less than 600mm. It is called "narrow band", so hot rolled coil is called hot rolled strip steel. As for the difference between hot rolled coil and cold rolled sheet, it is aimed at the rolling state of the steel plate. The hot rolled coil is made by rolling the hot rolled slab.
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 gas does the shear of the strip weld require for the welder?
Welding equipment includes welding machine and welding auxiliary mechanical equipment. According to the way of welding, it can be divided into two kinds of flash welding and welding.
Q:What does galvanized steel strip A6 mean?
The chemical and chemical reactions between the substrate and the molten bath of the hot galvanized steel pipe are complicated and the corrosion resistant structure is closely alloyed with zinc and iron alloy. The alloy layer is integrated with pure zinc layer and strip steel matrix. Therefore, it has strong corrosion resistance.
Q:What is the difference between steel strip and strip steel?
The difference is: the strip, that is used for processing into steel belt materials, iron and steel enterprise is produced by hot rolling cold rolling plate, a large volume of.
Q:What's the cutting edge of cold rolling strip?
Do you mean the cutting edge is the indication of the steel roll out of the factory? When the steel factory leaves the factory, the steel coil will have the burr and the cutting edge two kinds, the rough edge is the steel strip two, the edge is not neat. The trimming is the two sides of the steel band, and the width of the strip is certain when it is trimmed.
Q:What is the meaning of C hot strip material, B material is how to distinguish between
Due to work hardening of cold rolled steel plate, a certain degree of toughness is low, but can yield better than that used to cold spring piece parts, at the same time as the yield point is close to the tensile strength, so the use of risk is not predictable, prone to accidents in the load exceeds the allowable load.
Q:What is the difference between galvanized steel cold base galvanized steel strip and hot galvanized steel strip?
In addition because of the high density of zinc, galvanized steel coating with the same aluminium zinc plate in the price there is no advantage, because the control relationship between zinc flower, zinc plating is more difficult to control, and anti oxidation performance and ALuminum zinc is poor compared to several times, so now mainly in the aluminum zinc as the main building materials and its the performance is 3-4 times of zinc, but the current electronics industry because of influence of hot dip galvanizing plate conductivity, appearance or using mainly low coating, building materials mainly to hot-dip aluminum zinc 100g/ square meters above. The main hot dipped aluminum zinc is 55%AL and 44.5%Zn.
Q:Why does the strip bend when it is rolled?
The strip will bend after rolling:1) operation reasons, because the operator double pendulum adjustment is unreasonable, resulting in strip deviation.2) electrical reasons, due to the sudden decrease or disappearance of the tension of the coiler during the rolling process, lead to strip deviation and fracture.3) due to roll, roll grinding after serious pressure, taper, makes the school not to the operator in the rolling process of double pendulum regulation increases taper, will cause serious side light waves caused by shape defects, cause strip deviation and broken belt.4) strip edge control device failure, 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: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
