Description
Technical field
The invention belongs to field of metallurgy, and in particular to a kind of preparation method and applications of cast iron pushing off the slag device.
Background technique
Removing slag in molten iron, generally mainly by collection slag agent removal, but since slag viscosity is big, some small disintegrating slags can not be gone
Except clean, some factories are transferred to the casting of teapot packet, or design pushing off the slag sprue cup by subcontracting, by the molten iron handled well,
Or one layer of collection slag agent is spilt on molten iron surface, one piece of entirety is formed it into, is suspended in molten iron surface in packet in casting process always.
But teapot packet is not suitable for magnesium iron processing, needs to carry out ladle-to-ladle, and molten iron cooling is big, operates comparatively laborious.It is not applicable
In casting thin-wall part.Collection slag agent is spilt on molten iron surface, and tiny dregs are had in casting process can fall to sprue cup, even into
Casting, and it is poured the later period, monolith collection slag agent falls risk.Although can be kept off using pushing off the slag sprue cup big in the most molten iron of note
Block slag, but due to the factors such as impulse force of molten iron in casting process, tiny slag cannot be blocked completely.
Summary of the invention
Goal of the invention: in order to solve the deficiencies in the prior art, the present invention provides a kind of preparations of cast iron pushing off the slag device
Method and its application.
Technical solution: a kind of preparation method of cast iron pushing off the slag device includes the following steps:
Step 1: being cut using 3-10mm steel plate, wherein steel plate tip is consistent with casting ladle mouth-shaped, and smaller
In the packet mouth of casting ladle mouth, several apertures are got on the steel plate, for fixing with tapetum fibrosum；
Step 2: steel plate ready-made in step 1 is welded and fixed with a round steel, the bottom of steel plate and mouth are adopted
It is wrapped up with tapetum fibrosum；
Step 3: the hook at processing packet gate portions welding 2, is placed in steamed stuffed bun upper end for this device, this device should can
To contact with packet mouth, and gap is no more than 50mm around packet mouth.
As optimization: the tapetum fibrosum wall thickness is 15-60mm.
As optimization: the tapetum fibrosum refractory temperature is more than 1450 DEG C.
A kind of application of the cast iron pushing off the slag device of the preparation method preparation of the cast iron pushing off the slag device according to:
(1) 20T spheroidising packet is selected, makes profile-followed steel plate, and 20mm thick fiber blanket is wrapped in steel plate with finer wire
On, steel wire is not exposed at close to molten iron side；
(2) 2 hooks are welded in the nodularization packet top edge 20T, after the iron plate that hook position ensures to wrap up tapetum fibrosum is placed
It is almost seamless with packet mouth；
(3) liquid iron balling after treatment, slag hitting cover one layer of collection slag agent on molten iron surface after slag hitting；
(4) skimming device made is placed；
(5) it is poured, in casting process, cast iron pushing off the slag is suspended in always molten iron surface with device, it is formed in packet mouth
Bulk dregs are collected in a kind of structure similar to spout of a teapot and lid, collection slag agent, and all tiny dregs are blocked in casting process
After tapetum fibrosum, the collection slag agent of later period full wafer is poured also due to this device is blocked in casting ladle.
The utility model has the advantages that operation of the present invention is easy, at low cost, do not need ladle-to-ladle, solves tiny slag in molten iron and fall into cast gate
The problem of cup, is suitable for big pony ladle and is poured, highly-safe.
The device of the invention is needed to change except tapetum fibrosum periodically damages, and steel plate can be used permanently, low in cost；All is tiny
Dregs are blocked in tapetum fibrosum.
