Abstract
The invention discloses a vertical line slit type lap joint slag blocking casting system and a process, which comprises the following steps: the pouring device comprises a shaping plate, a pouring cup and a pouring head, wherein a transverse pouring gate and a vertical pouring gate which are communicated are arranged in the shaping plate, and the surface of the shaping plate is provided with the pouring cup which is connected with the initial end of the transverse pouring gate; the upper end of the vertical pouring gate is in lap joint with the horizontal pouring gate, and the lap joint distance is 2-3 mm. The invention makes full use of the slag-stopping function of the horizontal runner by utilizing the gap type lap joint of the vertical runner and the horizontal runner, so that slag can be kept in the horizontal runner as much as possible, thereby obtaining a clean casting and effectively reducing the rejection rate of the casting.
Description
Technical Field
The invention relates to the technical field of vertical line processes in casting process design, in particular to a vertical line slit type lapping slag blocking casting system and a process.
Background
Most pouring systems are bottom pouring or vertical gap type; for complex large-scale lathe bed castings, bottom injection and top injection are combined; a half of the pulley cast of not more than 100mm, etc., may be used in a ceiling type. In order to block slag, a slow flow type pouring system with a filter screen (the filter screen is arranged at the joint of a buffer tank and a cross gate) is often adopted. The sprue can be divided into three types; conical, flaky and snake-like.
However, in the vertical line casting, because the filter is rarely used for blocking slag, the slag blocking by the pouring gate process is particularly important, and if the slag blocking effect is not good, the casting is easy to scrap due to slag hole defects.
Disclosure of Invention
The invention aims to provide a vertical line gap type lap joint slag blocking casting system and process, which utilize the gap type lap joint of a vertical pouring channel and a horizontal pouring channel and fully utilize the slag blocking effect of the horizontal pouring channel to ensure that slag is kept in the horizontal pouring channel as much as possible, thereby obtaining a clean casting and effectively reducing the rejection rate of the casting.
In order to achieve the purpose, the invention adopts the following technical scheme:
a vertical line slotted lap slag-off casting system, comprising:
the pouring device comprises a shaping plate, a pouring cup and a pouring head, wherein a transverse pouring gate and a vertical pouring gate which are communicated are arranged in the shaping plate, and the surface of the shaping plate is provided with the pouring cup which is connected with the initial end of the transverse pouring gate;
the upper end of the vertical pouring gate is in lap joint with the horizontal pouring gate, and the lap joint distance is 2-3 mm.
In order to achieve the purpose, the invention adopts the following technical scheme: a vertical line gap type lapping slag stopping process utilizes the gap type lapping of a vertical pouring gate and a horizontal pouring gate, and fully utilizes the slag stopping function of the horizontal pouring gate to ensure that slag is kept in the horizontal pouring gate as much as possible;
the smaller the overlapping width of the vertical pouring channel and the horizontal pouring channel is, the harder the slag in the molten iron can enter the vertical pouring channel, the overlapping distance cannot be too small due to the limitation of the space size of the template, and the gap type overlapping with the overlapping size controlled to be 2-3mm can effectively prevent the slag from entering the vertical pouring channel by verification through actual production.
Compared with the prior art, the invention has the following beneficial effects:
the vertical pouring gate and the horizontal pouring gate are in gap type lap joint, the slag blocking effect of the horizontal pouring gate is fully utilized, and slag is left in the horizontal pouring gate as far as possible, so that a clean casting is obtained, and the rejection rate of the casting is effectively reduced. Under the unchangeable condition of cross gate and vertical gate overlap joint area, through the overlap joint distance of experiment vertical gate and cross gate, that is the coincidence distance that vertical gate stretches into in the cross gate, verify the pushing off slag effect of not unidimensional. In the conversion from the vertical line horizontal pouring gate to the vertical pouring gate, the flow rate of molten iron is not influenced, the contact area is certain, and the horizontal pouring gate can be filled with molten iron instantly, so that the smaller the width of the lap joint of the vertical pouring gate and the horizontal pouring gate is, the harder the slag in the molten iron enters the vertical pouring gate, the lap joint distance cannot be too small due to the limitation of the space size of a template, the verification is carried out through actual production, the lap joint size is controlled to be 2-3mm in the gap type lap joint, the slag can be effectively prevented from entering the vertical pouring gate, and a casting with better appearance is obtained.
