Description

Prevent the filter of lost foam casting molten iron turbulent flow slag inclusion

Technical field

The utility model is related to lost foam casting field more particularly to a kind of lost foam casting molten iron turbulent flow slag inclusions of preventing Filter.

Background technology

In the casting process of lost foam cast iron part, since in Castiron Melting manufacture craft, iron block, alloy are in magnetic induction loop Under the action of, high temperature is generated so as to melt, and there are a large amount of non-metal kinds thawing field trash, (cast iron phosphorus content is higher certainly inside iron liquid Body easily forms Slag inclusion), after molten iron taps a blast furnace, it need to carry out carrying out spheroidising and inoculation, be mixed with after Metamorphism treatment more Field trash, conventional casting method often because the presence of non-metallic inclusion causes product bad, are especially making requirement On the higher automobile die of hot metal purifying degree, since automobile board requires higher mould and die accuracy, the quality of mold also by Client proposes higher product appeal, has high abrasion, low deformation, flows and expect the functional characteristics such as smooth, only makes more high-purity The cast iron quality of degree gets to demand of the client to product, is not filtered in the running gate system used in usual casting process, Therefore, in casting process, molten iron turbulent flow easily occurs, slag a large amount of in molten iron is involved in casting, can not discharge, lead in time A large amount of slag occurs after causing the processing of spray using face, seriously affects performance.

Invention content

According to more than technical problem, the utility model provides a kind of filtering for preventing lost foam casting molten iron turbulent flow slag inclusion Device, it is characterised in that：Filter body is applied in traditional running gate system, and the tradition running gate system includes Zhi Tangdao, horizontal soup Road, ingate, the filter body include upper shell, filter screen, lower housing, the upper shell and lower housing be day circularly Square shape, size is identical everywhere with lower housing for the upper shell, and the upper shell is opposite with the square opening end of lower housing, securely docks Together, the upper shell is directly docked with the nose circle mouth of lower housing with Heng Tang roads, ingate, and the filter screen is located at upper casing Inside at body, lower housing docking, the filter screen size is respectively smaller than upper shell, lower housing square opening end inner wall size, the mistake Strainer is respectively interference fit with upper shell, lower housing, and the filter screen is respectively parallel to the round mouth end of upper shell, lower housing.

Using heat-resisting material, the upper shell uses Φ with lower housing for the upper shell, filter screen, lower housing 50mm connectors, the filter screen specification are 135*135*20mm.

The beneficial effects of the utility model are：The utility model is improved on the basis of original casting technique, is led to Convenient installation filter body is crossed, the casting flaws such as is mingled with to reduce cast-internal, it is this to prevent lost foam casting molten iron disorderly Flow the filter of slag inclusion, by each ingate can free independent installation filter body, molten iron can either be stablized and rushed Type speed reduces the generation of turbulent flow, can also improve degree of purity during molten iron stamp, reduces product slag inclusion, while significantly carry The mechanical property and product appearance quality of high product material, filter body are made of upper shell, filter screen, lower housing, upper casing Body and lower housing are hemispherical dome shape, upper shell and lower housing using Φ 50mm connectors, directly with Heng Tangdao, interior pour Mouth docking can also directly act on any one ingate, and rectification filtering is more targeted, optimize traditional running gate system, connect Convenient, not easily to fall off, filter screen is located at upper shell and inside is docked with lower housing, and filter screen was respectively with upper shell, lower housing It is full of cooperation, can quickly assembles, instant assembling.Filter screen specification：135*135*20mm effectively carried out slag inclusion in molten iron Filter, installation and dismounting are simple.
