What is the meaning of G305/30/100 WFG of steel grating plate?
First of all, the first "G" represents the steel grating plate, 305 represents the bearing flat steel 30mm*5.0mm, 30mm represents the height of the bearing flat steel, 5.0mm represents the thickness of the bearing flat steel, "30" represents the beari
What is the steel grating plate?
Steel grating plate is an open steel member which is fixed by welding or pressing lock by orthogonal combination of bearing flat steel and cross bar at a certain distance. The crossbar is generally made of twisted square steel, round steel or flat steel,
Technical measures in tubesheet in deep-hole drilling
Before drilling, drill a shallow hole with the same diameter as the drill bit, which can play a guiding and centering role when drilling. This step is especially necessary when machining holes with higher straightness requirements.
Key points of tubesheet in deep-hole drilling
With the continuous development of technology, tubesheet in deep-hole drilling is a typical structure of chip row deep hole drill, it is improved on the basis of the single blade chip row deep hole drill, the cutting edge is double-sided wrong tooth shape
Punching process of steel plate, steel plate machining process
NC punching and blanking: NC punching and blanking is to use the single-chip microcomputer on the NC punch to input the processing program (size, processing path, processing tools, etc.) of sheet metal parts in advance, so that the NC punch adopts various
SPA-H steel plate sample test results
Take a sample of SPA-H steel plate for metallographic analysis. Its matrix structure is ferrite and a small amount of pearlite. The grains are uniform and fine, and the grain size is 9-10. Tensile fracture morphology of SPA-H steel plate: all fractures ar
The smelting process of SPA-H steel plate
The molten iron used for smelting SPA-H steel plate must be pretreated by molten iron desulfurization, the sulfur content of the molten iron is ≤0.010% before entering the converter, and the slag on the surface of the molten iron must be removed. Nickel p
