Abstract
The invention discloses a production process for stuffing sand. The production process comprises the following steps: (1) subjecting a recycled waste magnesite-chrome brick to primary separation for iron removal, treatment with a jaw crusher and rough processing with a twin-roller machine so as to obtain a granular material with a size of 1 to 8 mm, removing iron, then carrying out processing with a pulverizer to obtain a granular material with a size of 0.1 to 3 mm and removing iron so as to obtain a semi-finished magnesium-chromium sand material; (2) successively adding semi-finished magnesium-chromium sand, quartz sand and an additive into a planetary mixer according to technical proportional requirements and carrying out stirring for 3 to 5 min so as to obtain finished stuffing sand; and (3) packaging the stuffing sand according to needs of clients. The production process has the beneficial effects that since the waste magnesite-chrome brick is used as a raw material, the purposes of environmental protection and reduction in production cost are achieved; and the stuffing sand prepared from the magnesite-chrome brick by using the process has a substantially improved free-opening rate.
Description
Technical field
The invention belongs to the casting equipment manufacturing technology field in metallurgy industry, specifically, it is related to a kind of drain
The production technology of sand.
Background technology
At present by the production technology of stuffing sand of the prior art, there is a problem of not environmentally, in addition producing
Stuffing sand self-opening rate low, and high cost.
Content of the invention
For above problem of the prior art, the technical problem to be solved is to provide a kind of environmental protection, life
Produce low cost, and the production technology of the high stuffing sand of the stuffing sand self-opening rate produced.
The technical problem to be solved employs the following technical solutions to realize:
A kind of production technology of stuffing sand is it is characterised in that comprise the steps:
(1) using magnesite-chrome brick discarded after recycling, break through first blanking ferrum, Hubei Province, to Kun machine thick addition 1-
8mm particulate material removes ferrum, is then processed by the crusher into 0.1-3mm particulate material again and removes ferrum, as semi-finished product magnesium
Chromium sand material；
(2) semi-finished product magnesia-chrome sand, quartz sand, additive are sequentially added to planet stirring by technology ratio requirement
In machine, stirring 3-5 minute is finished product；
(3) press client's stuffing sand size coupling packaging.
The invention has the beneficial effects as follows: to serve as raw material by using discarded magnesite-chrome brick, environmental protection and fall can be reached
The action effect of low production cost, the stuffing sand that in addition magnesite-chrome brick is made by above-mentioned technique, its self-opening rate can be made
Greatly improve.
