Abstract
The invention discloses a corrosion-resisting wear-resisting valve body. The valve body is made of an alloy material. The alloy material is prepared from the following raw materials in parts by weight: 55 parts to 60 parts of iron, 0.1 part to 0.45 part of boron, 1.4 parts to 1.9 parts of carbon, 0.7 part to 1.5 parts of vanadium, 6.5 parts to 10.3 parts of chromium, 2.5 parts to 4.1 parts of niobium, 0.2 part to 0.6 part of silicon, 6 parts to 10 parts of molybdenum, 0.9 part to 1.7 parts of manganese, 0.04 part to 0.06 part of tin, 1.0 part to 1.6 parts of copper, 2 parts to 3 parts of nickel and 0.05 part to 0.1 part of titanium. The corrosion-resisting wear-resisting valve body has the advantages that the formula is more reasonable, the manufactured alloy material is good in wear resistance, and the super wear-resisting valve body mad of the alloy material has better comprehensive performance and longer service life.
Description
Technical field
The present invention relates to a kind of manufacture method of alloy material, especially relate to a kind of alloy material of anticorrosive anti-wear valve body.
Background technology
Common valve is under deep-etching, poisonous and hazardous processing condition, and often poor sealing performance, easily leaks, and housing is easily bored a hole, and work-ing life is short, can not meet the particular requirement of permanently effective conveying poisonous medium.In order to meet the demand of permanently effective conveying poisonous medium, some entity and individual have developed the special valve of applicable high corrosive medium conveying, and for ensureing safe effect, the main parts size of valve needs to select is able to bear strong corrosion and wear-resisting alloy material.Often be furnished with different material prescriptions according to different service requirementss, a part of unit or individual be the patent of invention with regard to this type of alloy material application also.
As Chinese patent CN200610096864.3 discloses a kind of special type wear-resistant alloy material, the component of each element is: C, 1.0 ~ 2.5%; Si, 3.0 ~ 5.0%; B, 3.0 ~ 4.0%; Cr, 15 ~ 20%; Ni, 25 ~ 35%; Co, 20 ~ 30%; Mo, 3.0 ~ 5.0%; Fe, surplus.The beneficial effect of the program is the wear resisting property excellence of material, greatly extends the work-ing life of valve, and can repair, repeatedly use.Chinese patent CN201110341860.8 discloses a kind of valve steel material and preparation method thereof, it is mainly by constitutive material: matrix is Fe element, Cr, W, Ta, Mn, Al, P, S and C, by certain part by weight mixing, then obtain valve steel material through melting, thermal treatment and vacuum pouring.The feature of the program is that preparation technology is simple, stable components, cost are low, and on raw material, with the addition of multiple alloying element, has the various features such as good mechanical property, high temperature resistant, radioprotective, is applicable to the application of fusion reactor.Similar patent also has a lot, but this type of patent has a common shortcoming, mainly wear-resisting and erosion resistance is poor, is difficult to the high reliability request of the valve for chemical industry alloy material meeting high corrosion.
Summary of the invention
Problem to be solved by this invention is to provide a kind of anticorrosive anti-wear valve body, can not only be wear-resisting, also can tolerate corrosion, and has good hot hardness, can be widely used in each kind valve body.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of super abrasive valve body, formed by alloy material manufacture, described alloy material is prepared from by the raw material of following weight part: iron 55-60 weight part, boron 0.1-0.45 weight part, carbon 1.4-1.9 weight part, vanadium 0.7-1.5 weight part, chromium 6.5-10.3 weight part, niobium 2.5.-4.1 weight part, silicon 0.2-0.6 weight part, molybdenum 6-10 weight part, manganese 0.9-1.7 weight part, tin 0.04-0.06 weight part, copper 1.0-1.6 weight part, nickel 2-3 weight part, titanium 0.05-0.1 weight part.
As a further improvement on the present invention, described alloy material is prepared from by the raw material of following weight part: iron 57 weight part, boron 0.25 weight part, carbon 1.9 weight part, vanadium 1.4 weight part, chromium 9.8 weight part, niobium 3.7 weight part, silicon 0.35 weight part, molybdenum 5 weight part, manganese 1.5 weight part, tin 0.055 weight part, copper 1.5 weight part, nickel 2.5 weight part, titanium 0.05-0.1 weight part.
The invention has the advantages that, constitutive material formula is reasonable, and technique is simple, alloy has hot hardness and the high temperature compression strength of improvement, is applicable to being applied to the valve that high temperature occasion is made, the long service life of valve, qualification rate is high, substantially increases the quality of product, is applicable to extensively promoting.The element silicon of new interpolation, can play strengthening ferro element, puies forward heavy alloyed heat-and corrosion-resistant performance.
