Abstract
The invention relates to a reducer streamline type casting process and device for disc type castings. The disc type castings are obtained by adopting the step of casting by using a bottom pouring mode until a mould is full. The reducer streamline type casting device for the disc type castings comprises a template, wherein a disc type pattern is arranged on the template and is connected with a flow gate, and the flow gate is connected with a sprue cup through a pouring gate. The casting device provided by the invention is simple in structure, and convenient to model and clean. A little molten metal is consumed, and thus the yield of the castings is increased by 15-20 percent; due to the adoption of the flat horn type flow gate, the slag avoiding effect is good, and the qualified rate of the castings is high. The casting speed is high, and thus the production efficiency is increased. By adopting a lower casting temperature, energy resources are saved. Stability and smoothness are achieved during mould filling, and thus the sand washing defect is reduced, the consistency of metallographic structure and mechanical performances of the castings is good, and the qualified rate of the castings is increased.
Description
Technical field
The present invention relates to a kind of running gate system, be specifically related to a kind of streamlined pouring technology of dish class foundry goods reducing and apparatus for pouring thereof.
Background technology
Disk-like accessory is a kind of very common product, and its weight is generally less, produces so be highly suitable on the vertical line.But the vertical line running gate system that present most of producer adopts is mostly by forming with the lower part: cup, cross gate, vertical running channel, ingate, ingate, the pushing off the slag ability is strong, but the yield rate of product is on the low side, and is strict to pouring temperature, and consumes energy is many.Summary of the invention
The purpose of this invention is to provide a kind of streamlined pouring technology of dish class foundry goods reducing and apparatus for pouring thereof, improve yield rate, qualification rate, the production efficiency of producing product, reduce energy resource consumption.Reduce apparatus for pouring sand washing defective, the metallographic structure of the foundry goods of production and mechanical performance high conformity.
The streamlined pouring technology of dish class foundry goods reducing of the present invention, dish class foundry goods adopts the mode of rising pouring to pour into a mould, and namely gets product after the brimmer cast.
The brimmer cast is fully floated the sand/slag in the molten iron, reduces sand/slag blister defective.
The poring rate 3-5kg/s of molten iron, pouring temperature is controlled at 1300 ℃-1400 ℃.
The used apparatus for pouring of the dish class streamlined pouring technology of foundry goods reducing comprises template, and the dish-type apperance is set on the template, and the dish-type apperance connects ingate, and ingate connects cup by running channel.
Ingate is flat horn-like.Flat horn-like ingate has well keeps away the slag effect, has improved the qualification rate of product.
Running channel is the trapezoid cross section.
The trapezoid cross section size reduces to flat horn-like ingate gradually from running channel.The trapezoid cross section running channel adopts the adding pressure type design, has improved the mold-filling capacity of molten iron, can adopt lower temperature to pour into a mould.
Running channel sectional area size relationship is: S
2-1＞S
2-2＞S
2-3
The ingate center line is 0 °-45 ° with the relative angle of the vertical center line of dish class foundry goods.
On four jiaos on the template anti-striker is set.Prevent because operator's maloperation causes template to damage.
The dish-type apperance is arranged in diverse location, and foundry goods is full of die cavity simultaneously, enhances productivity.
Compared with prior art, the present invention has following beneficial effect:
Casting equipment of the present invention is simple in structure, and moulding, cleaning are conveniently.Molten metal consumption is few, has improved the yield rate of product, and its product yield rate can improve 15%-20%; It is effective to adopt flat trumpet type ingate to keep away slag, the casting qualified rate height.Cast has improved production efficiency fast; Adopt lower pouring temperature, save the energy; It is steady, smooth to fill type, has reduced the sand washing defective, and the metallographic structure of foundry goods and mechanical performance high conformity have improved the qualification rate of foundry goods.
