Technical field

The invention belongs to wear-resistant liner field more particularly to a kind of impact-resistant abrasion-proof lining boards based on chrome-moly steel.

Background technique

In China, ball mill application is very universal, is widely used in the industries such as metal mine, cement, electric system.Ball milling Machine lining material uses potassium steel more, but high manganese steel lining plate, in use there is many problems, high manganese steel lining plate is in ball mill Under interior grinding operating condition, the ability of processing hardening cannot be given full play to, is worn no resistance, simultaneously because potassium steel flow drag is low, Surface generates plastic deformation to liner plate in use, makes to be engaged between liner plate or even overall deformation, and fastening bolt is drawn It is disconnected, cause repair demolition extremely difficult.

Summary of the invention

A kind of impact-resistant abrasion-proof lining board based on chrome-moly steel, including first component and second component, first component and second component according to Weight fraction ratio is 3:1；

The first component is by following weight fraction ratio at being grouped as: Cr1.1-1.3%, Mo0.7-0.9%, C0.2-0.6%, Al0.1-0.3%、Mn0.4-0.6%、V0.15-0.35%、Co0.25-0.45%、Re0.3-0.5%、Ni0.1-0.5%、Cu0.45- 0.65%, TI0.05-0.15%, Si0.15-0.55%, surplus Fe；

The second component is by following weight fraction ratio at being grouped as: P1.25-1.45%, S1.2-1.4%, B1.25-1.45%, Nb0.9-1.1%, rare earth 1.5-1.7%, surplus are graphite powder.

Further, the first component is by following weight fraction ratio at being grouped as: Cr1.2%, Mo0.8%, C0.4%, Al0.2%, Mn0.5%, V0.25%, Co0.35%, Re0.4%, Ni0.3%, Cu0.55%, TI0.1%, Si0.35%, surplus Fe；Second Component is by following weight fraction ratio at being grouped as: P1.35%, S1.3%, B1.35%, Nb1%, rare earth 1.6%, surplus be graphite Powder.

It further, further include being distributed in outermost protective layer, the protective layer is by following weight fraction ratio at grouping At: polyurethane 3.5-5.5%, polystyrene 4-8%, aluminium hydrate powder 3-5%, antioxidant 2-4%, barium sulfate 1-3%, talcum powder 7- 9%, surplus is silica.

Further, the protective layer is by following weight fraction ratio at being grouped as: polyurethane 4.5%, polystyrene 6%, Aluminium hydrate powder 4%, antioxidant 3%, barium sulfate 2%, talcum powder 8%, surplus are silica.

The beneficial effects of the present invention are:

The present invention is designed by scientific and reasonable component, and good mechanical property, long service life can satisfy high rigidity, high tenacity With the requirement of high-wearing feature, strong shock resistance, wearability is good, and surface can be avoided to generate plastic deformation in use, With good practical and promotional value.
