According to the thickness, it is a thin steel plate (thickness < = 4 mm) and a thick steel plate (thickness "4 mm) medium plate.

In actual work, the steel plate with a thickness of <=20 mm is often called the medium plate, the steel plate with a thickness between 20-60 mm is called the thick plate, and the steel plate with a thickness of 60 mm is called the extra-thick plate, which is collectively referred to as the medium and thick steel plate. When the steel plates come out of the steel mill, they are coiled, and these steel plates are called flat plates after being leveled by the Kaiping machine"The hall opens the slab".The level of stress in the open plate is high, so the dimensional stability is poor.

With the different process parameters of Kaiping operation, the internal stress distribution is also different, and there will be different bearing capacity in different directions of vertical length. Moreover, this carrying capacity is difficult to measure with general strength indicators. Therefore, there will be a large welding deformation when the open plate is welded, and it is difficult to adjust.

Therefore, parts that require high appearance quality cannot be used with open plates.

It is generally considered that the hot-rolled steel plate of 20-40mm, the steel plate of medium and heavy plate is generally more than 20 and less than 100, and the width of the steel plate is basically less than 3300mm

Plate plate (1).Perverse, perverse.

2).Describe the expression as cold and serious.

Example]: Zhu Ziqing's "Miscellaneous Notes on Haixing": "The student finally added some money and handed it to him; Only then did he take it silently, his face still flat, as if he was disdainful.

Mao Dun's "Color Blindness": "But Instructor He's cat face does not have a single wrinkle. ”

Original meaning: a thin woodblock for a hostel or on-site dormitory.

Description: The ancient hostel or construction site dormitory is poorly built, and the thin woodblock is not used to isolate the room with an earthen wall, which saves materials and labor, and the cost is low, but the sound insulation effect is poor, so it can only be used. The arrangement of the sleeping berths is:

A bed is arranged on each side of the thin woodboard, and both pillows are located on one side of the thin woodblock. In this way, "mirror symmetry" is formed, and this kind of woodblock that forms "mirror symmetry" is called "board".
