Technical field:
The invention belongs to the equipment technical field of producing stainless steel casting blank in the stainless steel industry, particularly relate to a kind of stainless steel water chill casting base machine and stainless steel water chill casting blank technology thereof.
Background technology:
Stainless steel product is to realize through smelting, strand, rolling technical process at present.Strand production has two kinds of processes, and the one, traditional die casting injects the pig mold inner chamber with molten steel and becomes base.The shortcoming of this method is: the cavity shape of pig mold is simple in structure, tapering must occur, can not be oversize, thereby the steel billet of casting not only has tapering, and also shape and size all are restricted; Setting time is long during production, and interior tissue has segregation and shrinkage cavity, and the volume recovery of steel billet is low, consumption mould rate height; Production operation temperature height, dust is serious, and labor strength is big; Be not easy to field management and realize mechanization production.The 2nd, the casting blank of continuous casting machine method.This method investment is big, uses complex process, and supporting many with subsidiary conditions, occupied ground is big, changes base type difficulty, the special-shaped base production of incompatibility special shape, also incompatible single stove production and many kinds, small lot batch manufacture.
Summary of the invention:
Goal of the invention: the invention provides a kind of stainless steel water chill casting base machine and stainless steel water chill casting blank technology thereof, its purpose is to overcome above-mentioned process using pig mold inner chamber and becomes the tapering that has that occurs in base and the casting blank of continuous casting machine method, shape and size are all restricted, the production setting time is long, interior tissue has segregation and shrinkage cavity, change base type difficulty, the problem that aspects such as the abnormal shape of incompatibility special shape, single stove production and many kinds, small lot batch manufacture exist.
Technical scheme: the present invention is achieved through the following technical solutions:
A kind of stainless steel water chill casting base machine, this machine mainly is made up of host machine part, fluid power system, cooling water recirculation system, molten steel running gate system and strand hoisting device, it is characterized in that: host machine part wherein is that body is arranged on the frame and flexibly connects by bindiny mechanism, die body is fixed on the body by screwed pipe, form the strand die cavity in the die body, the upper end of die body has dead head corresponding with the strand die cavity, and the cast chassis is established in the die body lower end, and the cast chassis connects with the molten steel running gate system; The folding mould oil cylinder that links to each other with die body, hydraulic locking oil cylinder, horizontal sliding oil cylinder and strand suspender oil cylinder are formed fluid power system; The skin of die body is provided with the water crack, and the water crack communicates with cooling water recirculation system.
Die body be split, full steel structure, it be by liner and water crack, shell body and be arranged on liner and shell body between the metal short cylindrical constitute.
Be provided with a dead head feed trumpet on frame, the bottom of dead head feed trumpet is arranged on the cast chassis, and building in the rectangular groove on cast chassis has runner brick with holes, forms the runner brick road; The runner brick road communicates with strand die cavity in the die body by sprue gate.
Die body is many groups, and the many groups strand die cavity that constitutes in its die body is in parallel with the molten steel running gate system respectively.
The upper and lower side of die body has the water distribution box, it communicates with the water crack, one or more water holes that have internal thread and seal groove are arranged on the water distribution box plane, be communicated with body upper tank, bypass channel by screwed pipe, bypass channel links to each other with water pump by water inlet pipe, water leg links to each other with tank by return pipe, and tank links to each other with water pump by pipeline.
Frame is provided with safe cushion block, and what link to each other with the safety cushion block has a safe cushion block pull bar.
In body and the bindiny mechanism that frame links to each other four linkage and two pairs of extension spring mechanisms are arranged.
A kind of stainless steel water chill casting blank technology is characterized in that: molten steel is from top to bottom to inject during from steel ladle pouring to feed trumpet, through cast chassis, runner brick road, injects from bottom to top in the strand die cavity by the running channel bleeder again; Mold cavity is in the static state of no external force effect; By the outer cooling water circulation cooling of strand die cavity, molten steel cooling, crystallization rapidly from bottom to top, solidify, become base, cast finished product; Remove dead head and insulation slag, open locking cylinder, horizontal sliding oil cylinder and die sinking oil cylinder, suspender oil cylinder successively, hang out strand is disposable with suspender.
The end face of its strand die cavity one or both ends is made for the oblique angle; The cross section of strand die cavity can be made into rectangular, square, round and special-shaped, its length at 500-4000mm, width in 100-2000mm, the scope of thickness at 60-600mm.
Advantage and effect:
The present invention can solve the problem that exists in the stainless steel casting blank production in the past well.The mold cavity that molten steel injects the strand machine by the quick current-sharing of bottom running is in the static state of no external force effect, under the cooling water condition, forces cooling, and rapid crystallization is frozen into base.Molten steel solidifies from bottom to top, carries out feeding from top, the finished product rate height of casting, and surface quality is good, inside steel billet dense structure, flawless, bulge, pore and shrinkage cavity.The strand machine can cast out required different size, different size, difform stainless steel billet as long as change die body and the technological parameter of adjustment cooling water.The conversion product variety is convenient, has wide range of applications.Poring rate is fast, and the die sinking time of moulding adobe blocks is lacked the production efficiency height.Generally can in 1-3 minute, pour into a mould and finish.Solidify and to realize in back one minute that die sinking moulds adobe blocks.The strand temperature is still very high when moulding adobe blocks, and with good conditionsily can directly enter mill milling.This casting machine small investment, instant effect, cost is low, and floor space is few, and is with short production cycle.The die body liner can reach 10 in the temperature distortion condition following service life
4Inferior, need only change die body when surpassing access times and can continue to produce.Quality of cooling water does not have specific (special) requirements, as long as be no more than 70 ℃.Cooling water is taked the closed circulation mode, and loss is little, and other water for industrial uses can be warmed oneself or do to the high-temperature water of discharge.This casting machine is rational in infrastructure, and is easy to use, is easy to grasp, safe and reliable.Be applicable to large, medium and small enterprises of producing stainless steel, be particularly suitable for medium-sized and small enterprises and single stove production.
