Possibly when somebody hears the words “Conveyor Roller,” the thing that immediately rushes into their mind is nothing. Then how about hearing of “Steel Roller,” still nothing? It's all right. In the following I will lead into the world of Steel Roller and tell you how to judge whether it is good or not. These days, there are so many sellers take to adjustable foot hardware suppliers
. Among them, an individual really provide good quality products, but an individual just mix fake ones to cheat customers. So you have to be more careful when choose Steel Roller, better to depend on requirements followed.
Firstly, depend on microstructure. Cast structure of substrate of good plastic Box Handling
should be austenite and martensite, with shapes of graininess, block or strip and higher impact ductility and hardness. If not, at the very least, should own one of the properties.
Secondly, depend on working layer hardness. Hardness of some alloy forged steel rolls is formed by superficial hardening, which directly leads to reduced impact ductility. And since limited hardness penetration, formed high hardness working layer is thin and uneven, and a big gap between surface and inner will be there. The worst thing is hardness will greatly decreased and lifetime will be greatly narrowed if the gap beyond quenched case. Therefore, when choose Steel Roller; please remember to check goods with good harden ability and stable quality.
Thirdly, depend on wear-resisting property. We all know material wear-resisting property not only decided by its own macro hardness, but also by obdurability. So if you have to pick out good tapered conveyor roller
, don't forget to look into materials used.
Fourthly, depend on adaptation to working environment. GCr15 steel, 9CrSi steel and D2 steel made in China and America are suitable to work under cold situation, while 3Cr2W8V and H13 also made in the two countries must work under hot situation. Now it's clear you should choose according to your need based on your situation.
Fifthly, surface of bad steel rollers will become crude and stick with scarification after being used. While good quality steel rollers will never ever face this kind of problems, but present you with excellent appearance. I fancy, you must know how to choose now.
Lastly, as usual, the higher the price, the better the steel roller will be. Therefore, if Conveyor Suppliers provide you an extremely low price, think twice. After all, the higher is the price; the better is the quality of the merchandise.
