Abstract
The utility model relates to a wear-resistant accessory for metallurgy and mining, in particular to a two-liquid alloy lining board which comprises a board body with a working side and a supporting side. The board body is composed of a high alloy steel layer high in hardness and a low alloy steel layer high in toughness, the working side is provided with the high alloy steel layer, and the supporting side is provided with the low alloy steel layer. The working side of the board body is made from high alloy steel high in hardness, the supporting side is made from low alloy steel high in toughness, hardness and toughness are organically combined, and accordingly wear resistance and impact toughness of the board body are increased greatly and the service life of the two-liquid alloy lining board is prolonged.
Description
Technical field
The utility model relates to the abrasion-proof accessories of metallurgical mining usefulness, is the liner plate of metallurgical mining grinding machine specifically.
Background technology
According to statistics, the annual metal wear resistant material that consumes of China is about more than 3,000,000 tons, wherein uses on the liner plate of metallurgy mining just to reach about 100,000 tons.At present, the material of liner plate generally adopts ZGMn13 potassium steel, and it has good abrasion resistance and certain impact flexibility.The impact flexibility of ZGMn13 Hadfield steel is very high, can reach 200J/cm2, and original hardness is no more than HB230, but under high impact load, working surface can produce hardening effect, and its case hardness can reach HRC42-48, and the center still keeps good toughness.Yet inadequate in when work such as impact energy, ZGMn13 austenite surface impacts hardening effect can not fully produce, and the potassium steel surface does not reach high rigidity, and plate body is quick-wearing very.In addition, the yield limit of potassium steel is lower, in use easily sends plastic deformation.In addition, have the hardness matching problem between liner plate and the abrasive media, abrasive media hardness generally should be higher than about liner plate hardness HRC3 is advisable.But at present a lot of ore deposit factories use the abrading-ball of low-chromium cast-iron or rich chromium cast iron as abrasive media, its hardness is higher than the hardness of high manganese steel material far away, can cause like this potassium steel toughness under low impact load to be had a surplus and wearability is inadequate, thereby so that wear out failure is accelerated, the plate body distortion is serious, and service life is short.
The utility model content
For above-mentioned technical problem, the utility model provides a kind of biliquid alloy lining that had not only had toughness preferably but also had higher hardness.
The technical scheme in the invention for solving the above technical problem is: a kind of biliquid alloy lining, formed by the plate body with active side and support-side, described plate body is comprised of the high-alloy steel layer of high rigidity and the low-alloy steel layer of high tenacity, described active side is the high-alloy steel layer, and support-side is the low-alloy steel layer.
Further, the high-alloy steel layer of described plate body and low-alloy steel layer adopt biliquid continuous pouring moulding.
As can be known from the above technical solutions, the active side of the utility model plate body adopts has the high-alloy steel of high rigidity as material, and the support-side employing has the low-alloy steel of high tenacity as material, hardness and toughness are organically combined, greatly improve wearability and the impact flexibility of plate body, prolonged service life.
Description of drawings
Fig. 1 is lining plate structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with Fig. 1 the utility model is described in further detail:
The utility model comprises the plate body 1 with active side and support-side, and described plate body is comprised of the high-alloy steel layer 11 of high rigidity and the low-alloy steel layer 12 of high tenacity, and described active side is the high-alloy steel layer, and support-side is the low-alloy steel layer.Because active side adopts the high-alloy steel with high rigidity as material, has increased the wearability of active side, and support-side adopts the low-alloy steel with high tenacity as material, can bear larger impact.
The composition of high-alloy steel of the present utility model generally contains Cr:16%-20%, C:2.8%-3.2%, and Mn:1.0%-1.5%, Si:0.8%-1.3% etc. also contain rare element, and the processing of going bad; The composition of low-alloy steel generally contains C:0.35%-0.6%, Cr:0.8%-1.2%, Mn:0.5%-0.8%, Si:0.4%-0.8% etc., and the processing of going bad.The utility model organically combines hardness and toughness, and be to accompany with the 3-6 of common potassium steel as material its service life, has greatly reduced the labour intensity of changing liner plate, has reduced the labour, has saved cost and resource.In implementation process, the described plate body of utility model adopts the biliquid continuous pouring, makes whole plate body rapid shaping, and combination is integrated.
Above-mentioned embodiment is only for illustration of the utility model, and be not to be to restriction of the present utility model, the those of ordinary skill in relevant technologies field, in the situation that does not break away from the utility model spirit and scope, can also make various variations and modification, so all technical schemes that are equal to also should belong to category of the present utility model.
Claims (2)
1. a biliquid alloy lining is comprised of the plate body with active side and support-side, it is characterized in that: described plate body is comprised of the high-alloy steel layer of high rigidity and the low-alloy steel layer of high tenacity, and described active side is the high-alloy steel layer, and support-side is the low-alloy steel layer.
2. a kind of biliquid alloy lining according to claim 1 is characterized in that: the high-alloy steel layer of described plate body and low-alloy steel layer employing biliquid continuous pouring moulding.
