Description
Technical field
The utility model relates to the casting mold device, especially a kind of casting mold device of double-fluid double metal vertical-parting tup.
Background technology
At present; The wear-resistant metal material foundry goods is widely used in industries such as metallurgy, mine, harbour, cement, electric power, coal, building materials; In each industrial class, workpiece and equipment lost efficacy rapidly because of wearing and tearing, and the foundry goods wearing and tearing can cause catastrophic harm of metal works and surprising economic loss.The economic loss that China every year causes because of the wearing and tearing of metal material foundry goods is up to 100,000,000,000 RMB, and only abrasive wear just consumes more than 300 ten thousand tons of wear-resistant metal materials every year, but also with annual 15% speed increment.So the development of high life antifriction metal (AFM) foundry goods and the long-term stability development that use is related to national economy.
The material that domestic existing wear resistance castings uses is mainly: austenite abrasion-proof potassium steel and high-chromium white cast iron, these materials all belong to homogenous material.Just wear-resisting under the operating mode that potassium steel is only big in impulsive force, stress is high, abrasive material is hard.When the matrix of high-chromium white cast iron was martensite, its anti-wear performance was best, but martensitic toughness is relatively poor.Some wear resistance castings, and though through the composition adjustment, can suitably improve foundry goods toughness, foundry goods significantly reduced in use because of the personal injury that fragmentation caused, but casting hardness descends the reduction in service life.Therefore the homogenous material foundry goods shows on combination property not as people's will.
Existing bimetallic pouring technology is made the casting mold device of compound casting, and the cast compound casting has guaranteed the wearability that working portion is good, guarantees the toughness that other position is good simultaneously again.But with the compound casting that this casting mold device is made, compound area≤80% much belongs to the welding of liquid and solid, and the bond strength at bimetallic interface is not high, only is applicable to static wear working condition, for example liner plate.But for the dynamic wear working condition that impacts inclement condition,, occur wearing layer in the use easily, make the foundry goods of production have bigger potential safety hazard in use along bimetallic boundary breaking, the accident that comes off, fly out like tup.
Bimetallic technology is to adopt in casting mold, to imbed the semi-finished product foundry goods that the special combination face is arranged that waters in advance in advance, pours into composition metal again, and bond strength is lower, and technology is loaded down with trivial details.The cast of the most usage level somatotype of casting mold monotype, efficient is also low.
In a word, use the casting mold device complex production process of existing foundry goods, reduced operating efficiency and casting quality; Make the anti-wear performance and the toughness of foundry goods relatively poor on combination property, have bigger potential safety hazard; Workpiece and equipment lost efficacy rapidly because of wearing and tearing, had shortened service life, and the waste mass energy causes surprising economic loss; Take a lot of work, time-consuming, the effort, working strength of workers is big, has increased production cost.It is the anxious for a long time insoluble again technical barrier to be solved in this area.
In view of the foregoing, the casting mold device of existing foundry goods needs to improve.
