Abstract
The invention relates to a aluminum-containing high-chromium cast iron-type abrasion-resistant alloy, which is characterized in that the contents of alloying elements in the alloy are within the following ranges: chromium is 20-40 percent, carbon is 4-7 percent, and aluminum is 0.7-7 percent.
Description
Technical field
The present invention relates to a kind of aluminium rich chromium cast iron type wear resistant alloy that contains, belong to metal material field.According to this composition; This alloy that mode through casting, built-up welding or spraying forms; Can be widely used on the wearing piece of machinery of industries such as coal, electric power, metallurgy, machinery, chemical industry, such as the built-up welding reparation and the manufacturing of power plant's medium-speed pulverizer grinding roller roller shell and mill liner plate, cement mill vertical mill roll sleeve and mill liner plate, Iron And Steel Plant's slag vertical mill roll sleeve and mill liner plate.
Background technology
Rich chromium cast iron is as a kind of typical high-abrasive material; Be widely used,, can on the basis of rich chromium cast iron, add alloying elements such as vanadium, tungsten, titanium, boron usually in order further to improve wear resistance; The present invention is through adding the duraluminum element, improves wear resistance.Aluminium is the alloying element of strengthening matrix, can improve hardness after the adding appropriate amount, improves wear resistance.
Summary of the invention
On the basis of common high-chromium cast iron alloy, improve wear resistance through adding an amount of aluminium element.
Wear resistant alloy of the present invention is characterized in that containing in the alloying constituent alloying element of following content:
Chromium 20～40%; Carbon 4～7%; Aluminium 0.7～7%.
Alloying constituent of the present invention has following examples:
(1) chromium 20%, carbon 4%, aluminium 5%.
(2) chromium 25%, carbon 4.5%, aluminium 4.2%.
(3) chromium 30%, carbon 5.2%, aluminium 6%.
(4) chromium 35%, carbon 6.5%, aluminium 2.5%.
(5) chromium 40%, carbon 6.5%, aluminium 2.3%.
(6) chromium 25%, carbon 6%, aluminium 5%.
(7) chromium 30%, carbon 5.5%, aluminium 1.0%.
(8) chromium 30%, carbon 5.9%, aluminium 4%.
Typically used can be applied to slag Vertical Mill, cement mill raw material Vertical Mill, power plant's medium-speed pulverizer wearing piece etc.
Alloy of the present invention is not restricted to the described embodiments, any in claims of the present invention require the scope of protection improvement and change all within protection scope of the present invention.
