Lid of well of nodular cast iron divides rubiginous way correctly

What does the kind dividing rust that well of nodular cast iron builds have? Introduce to everybody below:

Lid of well of nodular cast iron has rusty circumstance to happen rarely generally speaking, but once appeared this kind of phenomenon, we need to undertake dividing rust to its, how should undertake dividing rust so, an article tell unship simply for everybody.

The kind dividing rust that builds to well of nodular cast iron at present has two kinds, one kind is cast shoot except rust, additionally one kind is eject divides rust, this is both it is to existing of difference, so called cast shoot except rust, basically be the impeller that uses high speed of the engine that throw ball to rotate piece, shoot what abrasive disperses the face that covers to well of nodular cast iron, use collision general the rubiginous mark of its surface and ear purify.

And eject divides rust is a course grease depart is treated compress air general abrasive from nozzle high speed ejective, the exterior collision that uses pressure general crocus and shell of well of nodular cast iron undertakes dividing rust. It is everybody correctly to what well of nodular cast iron builds to explain this simply except rubiginous means, when we encounter this kind of situation, above two kinds of methods are OK and optional firstly.

1, compare with cast-iron photograph, nodular cast iron has some advantages in intensity respect. The tensile strength of nodular cast iron is 60k, and cast-iron tensile strength has 31k only.

2, of nodular cast iron succumb intensity is 40k, and cast-iron did not show succumb intensity, and appear eventually rupture.

The intensity of nodular cast iron - cost is compared far excel is cast-iron.

3, the intensity of the intensity of nodular cast iron and cast steel can be compared. Nodular cast iron is had taller succumb intensity, its succumb intensity is 40k, and of cast steel succumb intensity has 36k only.

In domain of major municipal application, be like: Water, brine, vapour, the corrosion resistance of nodular cast iron and fight oxidisability to exceed cast steel.

4, the micromechani of bulbiform black lead as a result of nodular cast iron, in respect of abate and oscillatory ability, cast steel of excel of nodular cast iron, accordingly more be helpful for reducing stress.

A when choose nodular cast iron main reason is comparing cast steel cost at nodular cast iron low. Cast-iron well lid maintains working low cost makes this kind of material more welcome, cast efficiency taller, less also the machine of nodular cast iron finished cost

5, the all amount containing carbon in cast steel makes the carbon that exists as free black lead won't form structural chip, cast-iron the carbon inside is natural the form is chip of free black lead form.

6, after the pressure load component of nodular cast iron changes the craft of anneal cycle to handle through ferrite, the interstitial phenomenon that the chip black lead that the bulbiform structure of interior of nodular cast iron also can eliminate cast-iron interior produces easily.

7, in the microcoic photograph in nodular cast iron, can see break arrives after black lead ball stop. Inside industry of nodular cast iron, these black lead balls are called " interstitial terminator.
