The iron for producing large rolls of galvanized wire can be divided into two categories. It is a metal that is developed directly from the iron ore through the iron smelting plate. The main components of the ore are iron oxide, silica and other miscellaneous stones.
When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed into it, so that the data produced is called the general pig iron, which is also the material for the initial grade. According to the different requirements of industry, in the smelting furnace according to the standard allocation of alloying ingots into different weights, such as weaving, Ming, paper, Lang, silicon, etc., the data out of this refining is called gold ore.
Iron has gray iron, white iron and the above-mentioned combined gold ore, each of which has different characteristics, so in the industry, according to their different characteristics to transport exploration and selection. For example, in gray iron, its carbon exists in iron ore in the form of graphite, the crack is often gray, the quality is soft and the character is tough, simple filter cutting, and it is suitable for casting.
In white iron, its carbon is combined with iron to form iron carbide, the crack appears white, the quality is strong and brittle, and it is the material of malleable steel. Alloying grade is composed of various alloying elements, and its composition and structure are also different. Because the alloying element in the ore iron can make the copper thickness, hardness, impact force, strength, absorption rate, elongation, so the alloy iron in the exercise of good iron, is an auxiliary element.
