Abstract
The utility model discloses a casting quantitative filter feed head, consisting of a molten iron container and a ceramic filter head, wherein, the ceramic filter head is positioned on the exit of the container. The utility model is characterized in that: the lower part of the ceramic filter head(4) has a funnel shape supporting piece(5); a gland(3) with a central through hole is arranged on the gland(3); the bottom of the gland has a convex component(6); and the central hole of the gland(3) is communicated the bottom of a plug(1). The utility model uses three slag removing theory, as suspension, filter and adsorption, to purify molten iron and uses a quantitative container, a high pressure head and a constant pouring speed to realize stable pouring, thus can effectively increase the inner quality of material and processing performance and enhance manufacturing efficiency.
Description
Technical field
The utility model belongs to Casting Equipment, and specifically, it relates to a kind of casting quantified filtering pouring cup.
Background technology
The iron liquid of Foundry Production can produce a large amount of field trashes in fusion process, its form has solid-state and liquid, and film shape, lumps are arranged, and fine graininess is also arranged.After molten iron poured into die cavity, they were mixed in the foundry goods, destroyed the foundry goods institutional framework, formed formation of crack, the performance of serious harm foundry goods, even cause fracture failure.To important security personnel's foundry goods, it is particularly important to remove these field trashes.Usually the cup that adopts in the Foundry Production is in casting process, a large amount of field trashes can't be removed, being easy to flow into die cavity with molten iron makes foundry goods produce slag inclusion, in addition, because artificial pouring operation instability adopts traditional cup molten iron flow velocity and variations in temperature big, is easy to roll up gas or cold shut, and current-following inoculation is difficult for evenly, and the casting quality fluctuation is big.
Summary of the invention
The purpose of this utility model is to provide a kind of casting quantified filtering pouring cup that can overcome above-mentioned defective, and it utilizes and suspends, filters and adsorb three kinds of slagging-off mechanism realization purifying molten irons, and utilizes volume quantitative, high pressure head, the constant speed of watering to realize stable cast.
For realizing above-mentioned utility model purpose, the utility model casting quantified filtering pouring cup, form by molten iron container and the ceramic filter piece that is positioned at its exit, it is characterized in that: the below of described ceramic filter piece is provided with funnelform support member, on the ceramic filter piece, be provided with gland, gland is provided with central through hole, and its bottom has protrudes the position, and the bottom of stick harness and the central through hole of gland are complementary.
The utility model casting quantified filtering pouring cup has the following advantages: (1). and can carry out omnibearing elimination to the solid slag in the molten iron, hydraulic pressure slag, subparticle slag, filter effect is more thorough, has improved the inherent quality of material effectively.(2). when molten iron injects container, can carry out current-following inoculation simultaneously, pregnant amount is accurate, and inovulant and molten iron are mixed full and uniform.Can prevent to help improving processing characteristics and pregnant effect owing to incomplete, inhomogeneous local rich Si that causes of fusing or rich Si hard point.(3). high pressure head, quantitatively constant speed cast, avoid and eliminated because of pourer's misoperation, neglect the fast waste products such as the pore that causes slowly, cold shut of neglecting, stablized production effectively, avoided artificial fluctuation.(4). the multiple sand casting of the swage non-riser technologies that adopt, filter is placed in and waters in the cup, helps down gate and before solidification shrinkage foundry goods is carried out liquid feeding, prevents that foundry goods from producing shrinkage cavity more.(5). in the multiple sand line of swage is produced, often occur making swage to open, even being stuck because of in time not removing cup.Adopt this cup to avoid this trouble fully, help ensureing the normal operation of production line.
Description of drawings
Fig. 1 is the structural representation of casting quantified filtering pouring cup.
The specific embodiment
As shown in Figure 1, casting quantified filtering pouring cup is made up of molten iron container 2 and ceramic filter piece 4, and the exit of molten iron container 2 is provided with funnelform support member 5, and ceramic filter piece 4 is positioned on the support member 5, support member 5 is the support member of ceramic filter piece 4, is again the poring rate controller.Be provided with gland 3 on ceramic filter piece 4, gland 3 is provided with central through hole, and its bottom has protrudes position 6.This protrusion position can be a circle boss at its bottom margin place, also can be salient point or other shape that several dispersions distribute, and can make ceramic filter piece 4 and gland 3 leave certain space like this, to increase the contact-making surface of molten iron and ceramic filter piece 4.The through hole of the bottom of stick harness 1 and gland 3 is complementary.
Static 3-5 second after high temperature liquid iron is poured molten iron container 2 into, agglomerate slag and liquid slag are suspended in the molten iron surface, and the fine particle slag of minority still mixes in molten iron.After stick harness 1 was transferred to, molten iron steadily sank, and the central through hole by gland 3 flows to ceramic filter piece 4, and the bits in the molten iron are filtered that piece filters and absorption, and molten iron is purified, and steadily flow into casting molds by the support member 5 with flow-control effect again.
Claims (1)
1. casting quantified filtering pouring cup, form by molten iron container and the ceramic filter piece that is positioned at its exit, it is characterized in that: the below of described ceramic filter piece (4) is provided with funnelform support member (5), on ceramic filter piece (4), be provided with gland (3), gland (3) is provided with central through hole, its bottom has protrudes position (6), and the central through hole of the bottom of stick harness (1) and gland (3) is complementary.
