Pig iron wheel is also called the iron wheel, the material is iron. Its capacity is very high, belongs to one of super-heavy castor; Because its material is iron hardness is higher, so the application of environment places are limited, it is widely used for leading to an iron wheels can't important factors. If without any requirements for the ground, it is definitely a good castor products. Pig iron wheel used for surface protection requirements is not high, or the rough concrete pavement, load resistance, high temperature resistant, commonly used in powered mechanical industrial equipment, storage cage, trolleys, high temperature and other harsh working environment, etc. Defect is has the indentation on the ground, is suitable for surface protection requirements is not high working environment. Caster casting process has the following characteristics: 1, generally use the wide raw material sources, castor castor casting casting cost is low. 2, casting process flexibility, high productivity, can be manual production, can also be mechanized production. And 3, the shape and size of caster casting parts is very close, the metal material is saved, and save machining time. 4, casting can produce all kinds of complicated shape of blank, especially suitable for the production with complex cavity parts blank, such as all kinds of boxes, cylinder, blade and impeller. 5, caster casting can not restricted by metal material, size, and weight. Caster casting material can be all kinds of cast iron, cast steel, aluminum alloy, copper alloy, magnesium alloy, titanium alloy, zinc alloy and all kinds of special alloy materials; Caster casting can be as small as a few grams, big to hundreds of tons; 5 mm to 1 m; Caster casting length can range from a few millimeters to more than ten meters. Although iron wheels because of its high hardness on the surface damage is serious, but it is very good in terms of bearing; In general metal wheel in the face of the ground damage is very big, so everyone in the choice to pay attention to this. Pig iron wheels, except for carrying on excellent high temperature resistant performance is also very good, so there are also many clients before using pig iron wheel instead of high temperature resistant wheel used in high temperature place.
