Q:What is hot and cold rolled steel plate? How to distinguish? What high hardness? Which will produce noisy eye?
As the name suggests, hot rolling, rolling temperature is high, so the deformation resistance is small, can achieve large deformation in rolling steel plate. For example, the general continuous casting slab thickness is about 230mm, and after roughing mill and finishing mill, the final thickness of 1~20mm. at the same time, because the steel plate width thickness ratio is small, the size precision is relatively low, not easy appear the flatness problem, mainly to control the convexity. For the organization required, generally through controlled rolling and cooling control is realized, microstructure and mechanical properties of the rolling temperature, finishing temperature and coiling temperature to control strip finishing. Cold, generally in the heating process is not open before rolling. However, because the strip thickness is small, it is easy to appear the flatness problem. Moreover, after cold rolling is finished, therefore, in order to control the dimensional accuracy and surface quality of steel strip, using a lot of tedious process. The cold rolling production line, equipment, process complex With the user to improve the shape and surface quality of the strip size precision, plate, cold rolling mill control model, L1 and L2 system, the shape control means relative to hot. And temperature is one of the important control index of rolls and strip.
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. Is that correct?
A steel strip is also a coil, usually a narrow strip, also known as a steel strip.
Q:Stainless steel plate and steel welding
Depends on your stainless steel plate number and steel brand, and then choose the corresponding electrode, in general, commonly used should be 304 stainless steel, steel bar should be Q235, so with 307 of the welding rod can be welded
Q:What are hot and cold plates?
Hot and cold plate is cold rolled sheet (coil) and hot rolled plate (coil) collectively.
Q:How do I print the steel plate?
In fact, the printing mode called "stencil printing", is a kind of porous printing, first use the typewriter in special Lazhi typing, or a stylus paint word pictures, and then let the wax paper attached to ordinary paper, ink in the painted pattern, through hole type or writing, and printing to the following the common paper.
Q:How can the steel plate of flat welding 10mm make its deformation smaller?
The most simple way is to set up a few blocks in the weld transverse positioning plate, welding seam after cooling in the two side gently hammering stress relief force dismantled.
Q:Is the steel plate 1.5 meters wide and 2 meters wide at the same price? .
The steel plate price is generally not the width, they only according to the different material steel plate, gives you to quote the unit price.
Q:The method of making spring steel for automobile?
Steel plate like spring can not be used as a knife. No material, easy to the teeth. If the shape of the tool is not required, the spring coil of the shock absorber can be used.
Q:What's the difference between profiled steel sheet and color steel plate?
The floor slab is mainly loaded with cement. Color steel plate refers to the color coated plate, with the color coated roll pressure type, the thickness of the basic below 0.6, there are many colors to choose, the thickest to 1. Mainly used in the walls and roofing of factories, instead of bricks and tiles.
Q:What are the problems encountered in the construction of steel sheet piles? How to deal with
Based on the soft, sometimes the construction was adopted into the adjacent pile phenomenon, measures is the number of adjacent piles are welded together, and in the application of play pile connected locking coated with butter and other lubricants to reduce resistance
