Common material now, steel structure steel structure (
Engineering structure)
The use of the demand is higher and higher, so the steel structure of the demand is higher and higher.
The use of steel structure we mainly use which material?
Commonly used steel structure material of main components: 1, silver board: 8 -
The thickness of 32.
Wide 180 -
600.
Dragon below 15000.
2, the coil: open and close board, decorative pattern plate kaiping.
In general, 1250 wide.
1500.
1800.
2000.
The thickness of 16 or less.
3, hot rolled slab.
4, H section steel, hot-rolled h-beam, high-frequency welding h-beam.
High temperature bearing development has a higher rated working load, low noise, big engineering warranty management to reduce costs, increase enterprise equipment need time operation, etc;
In discrimination analysis of high temperature bearing true and false, such research can by touch to play on the high temperature bearing steel to more quickly identify more accurately, this thought seal by hand to touch her, without a touch, but the use of nails on the steel seal gently touch technology can feel the existence of the steel seal.
Time component class material: steel, steel, steel, steel な ど hollow cold bend section steel, square tube, rectangular tube, pipe, high-frequency welded pipe, seamless tube, thermal expansion of seamless, spiral conveyor 15?
The diameter of the 45 days, more than 219, 16 or smaller wall thickness.
LSAW 30 -
The diameter of the 45 days, more than 400, 50 or less wall thickness.
Steel structure enterprise common structure material of the class material: as shown in figure 1, purlin: coil slitting with wide article or pressed together galvanized: wuxi (
Strip)
Such as black,
No galvanized)

Conventional color (
The sea is blue, and white, ivory white,
Also called white goose down, Chinese white)

High temperature bearing see high temperature shaft bearing damage, can be found that, in most cases, it may be the cause of them, in general, high temperature bearing fatigue damage caused by only a third of the occurrence of bad lubrication, and other one third of the pollutants into high temperature bearing or improper installation.
These damage type, however, have nothing to do with industrial high temperature bearing is high precision spare parts, so you need quite a long time to carefully, even if is a high performance high temperature bearing, if use undeserved, also cannot achieve the expected performance effect, easy to damage the high temperature bearing.
3, aluminum (
Al)
The zinc plate: baosteel origin (
Meishan)
Bluescope, joints and other 4, galvanized sheet, thickness below 3, 1000.
1250.
1500, etc.
Origin of masteel, tangsteel, benxi steel and so on.
High temperature high temperature bearing to see the shaft bearing damage, can be found in our most cases, it may be lead to their students, general corporations, fatigue damage caused by the damage of high temperature bearing company is one of only three points and technology of China from bad behavior occurs, the lubrication system and the other between development from three points of pollutants into a high temperature bearing or improper installation process.
