Abstract
The invention relates to a nickel-based alloy anvil for forging square and flat steels, which belongs to auxiliary facilities for metallurgical production. The nickel-based alloy anvil consists of a nickel-based alloy layer and a surfacing layer. The percentages by weight of the chemical components of the nickel-based alloy layer are as follow: C: 0.50 to 0.60, Si: 0.10 to 0.40, Mn: 0.65 to 0.95, P: 0.030 or more, S: 0.030 or more, Cr: 1.00 to 1.30, Mo: 0.45 to 0.55, Ni: 1.50 to 1.80, V: 0.07 to 0.12 and the balance of iron and inevitable impurities. The nickel-based alloy anvil is characterized in that a preparation method of the nickel-based alloy anvil includes the following steps: a pit is dug in the top surface of a nickel-based alloy anvil; the nickel-based alloy anvil is heated to 350 DEG C, and as the temperature of 350 DEG C is kept, a Ni847 welding rod is used for performing three times of surfacing in the pit; after surfacing is complete, the anvil is put into an annealing furnace and heated to 550 DEG C, and is treated by heat under constant temperature for 24 hours; the power is cut off, and the anvil is naturally cooled in the furnace for 10 to 12 hours. The service life of the nickel-based alloy anvil is long.
Description
Technical field
The invention belongs to metallurgical production auxiliary equipment, be specifically related to a kind of quick forging machine nickel-base alloy flat anvil.
Background technology
The special hammering block of quick forging machine belongs to the large-scale tool of production in the steel ingot side of forging band steel production process, mainly bears quick forging machine to pressure distortion in steel ingot forging process.Quick forging machine is by the square band steel forging deformation of hammering block to different size.Along with the change in market, user requires to improve constantly, when forging side's band steel, because of hammering block be in the condition of high temperature always under work, hammering block surface temperature distortion is serious, causing the defect such as surface indentation, crackle to produce because being heated simultaneously, during forging, hammering block blemish being taken on product, affect the product quality of dispatching from the factory.
Though through post employee to measures such as inspection, polishings in time, DeGrain, the square band steel after often forging is because of the quality problems such as surface quality, dimensional tolerance, and lower operation is had strong complaints.
Summary of the invention
In order to avoid the surface quality defect of the quick forging machine side of forging band steel, the present invention proposes a kind of forging side band steel nickel-base alloy hammering block.
Technical scheme of the present invention: the nickel-base alloy hammering block of a kind of side of forging band steel, be made up of nickel base alloy layer and overlay cladding, described nickel base alloy layer chemical composition mass percent is: C:0.50 ~ 0.60, Si:0.10 ~ 0.40, Mn:0.65 ~ 0.95, P :≤0.030, S :≤0.030, Cr:1.00 ~ 1.30, Mo:0.45 ~ 0.55, Ni:1.50 ~ 1.80, V:0.07 ~ 0.12, all the other are iron and inevitable impurity; It is characterized in that its preparation method digs groove at the sub-upper surface of nickel-base alloy flat anvil; Nickel-base alloy flat anvil is heated to 350 degree and in groove, carries out three built-up welding with Ni847 welding rod under keeping the temperature of 350 degree; After a front built-up welding completes, a rear overlay-operation is carried out at interval for 4 ~ 5 hours; After built-up welding completes, hammering block is put in annealing furnace and be heated to 550 DEG C, carry out constant temp. heating process in 24 hours; Hammering block is also naturally cooled 10 ~ 12 hours by power-off in stove.
Described nickel-base alloy flat anvil is cube.
Described overlay cladding is made up of transition zone, intermediate layer and grinding layer, and wherein the thickness of transition zone is 4mm, and the thickness in intermediate layer is 6mm, and the thickness of grinding layer is 31mm.
Surface meets the band steel instructions for use of forging side, and will heat Ni base alloy before forging, hammering block overlay cladding is high temperature alloy, and feature is high temperature red hardness, resistance to impact.
After hammering block installation, before every use, must with old steel ingot or workpiece heat to 1100 DEG C, then clamp heated steel ingot with 2 hammering blocks or workpiece carries out preheating, summer preheating time need be greater than 30 minutes, and winter need be greater than 45 minutes, can forge and press after hammering block preheating, make the red hardness of hammering block to give full play to like this, the normal use of guarantee hammering block, meets the requirement of Forging Technology.
The present invention due to surface has can the nickel-base alloy layer of resistance to about 800 degree, the deflection produced in forging process is less, greatly reduces the time changing hammering block and reconditioning hammering block; Hammering block extends service life, and average one secondary service life was at about 9 months.
Existing hammering block makes the life-span be about 1 month.
Detailed description of the invention
1, nickel-base alloy (Ni847) welding rod built-up welding transition zone (transition region thickness is 4mm) is used
A) doing the degree of depth at the upper surface of 56NiCrMoV7 flat anvil is 41mm, and width is the groove of 300mm.
B) carry out clean to hammering block surface before welding and checked whether be full of cracks;
C) 56NiCrMoV7 hammering block is heated to 350 degree, and welds at the temperature of 350 degree.
2,4 to 5 hours, interval, uses nickel-base alloy (Ni847) welding rod built-up welding intermediate layer (intermediate layer thickness is 6mm)
A) carry out clean to hammering block surface before welding and checked whether be full of cracks;
B) hammering block is heated to 350 degree, and welds at the temperature of 350 degree.
3, in like manner built-up welding grinding layer (grinding layer thickness is 33mm)
After built-up welding completes, put in annealing furnace and be heated to 550 DEG C and heat-treat, constant temperature eliminates internal stress in 24 hours, cooling 10 ~ 12 hours naturally in stove after power-off.
4, the compound hammering block intensity after Overheating Treatment is 900 ~ 1050N/mm
2.
5, control: check whether surface has be full of cracks.
Ni847 welding rod chemical composition is as following table:
