Embodiment 1

[0013] A production process of drainage sand, comprising the steps of:

[0014] (1) Use waste magnesia-chrome bricks after recycling, remove iron through primary selection, jaw breaking, and coarsely add 1mm pellets to remove iron, and then process them into 0.1mm pellets to remove iron through a pulverizer, which is a semi-finished product Magnesia chrome sand material.

[0015] (2) Add semi-finished magnesia-chrome sand, quartz sand and additives in turn according to the technical ratio requirements and stir in the planetary mixer for 3 minutes to obtain the finished product.

[0016] (3) Match the packaging according to the size of the customer's drainage sand.

Embodiment 2

[0018] A production process of drainage sand, comprising the steps of:

[0019] (1) Use waste magnesia-chrome bricks after recycling, remove iron through primary selection, jaw breaking, and coarsely add 8mm granules to remove iron, and then process them into 3mm granules to remove iron through a pulverizer, which is semi-finished magnesium Chrome sand.

[0020] (2) Add semi-finished magnesia-chrome sand, quartz sand, and additives to the planetary mixer in sequence according to the technical ratio requirements and stir for 5 minutes to obtain the finished product.

[0021] (3) Match the packaging according to the size of the customer's drainage sand.

Embodiment 3

[0023] A production process of drainage sand, comprising the steps of:

[0024] (1) Use waste magnesia-chrome bricks after recycling, remove iron through primary selection, jaw breaking, and coarsely add 4mm granules to remove iron, and then process them into 1.5mm granules to remove iron through a pulverizer, which is a semi-finished product Magnesia chrome sand material.

[0025] (2) Add semi-finished magnesia-chrome sand, quartz sand and additives to the planetary mixer in turn according to the technical ratio requirements and stir for 4 minutes to obtain the finished product.

[0026] (3) Match the packaging according to the size of the customer's drainage sand.

Abstract

The invention discloses a production process of stuffing sand. The method comprises the following steps of: (1) adopting recycled waste magnesite-chrome bricks, carrying out primary separation and iron removal, jaw crushing and rough addition into 8mm granules by using a roller machine to remove iron, and then processing into 3mm granules by using a crusher to remove iron, so as to obtain a semi-finished magnesite-chrome sand material; (2) sequentially adding the semi-finished magnesium-chromium sand, quartz sand and an additive into a planetary stirrer according to the technical proportioning requirement, and stirring for 5 minutes to obtain a finished product; and (3) matching and packaging according to the size of customer stuffing sand. The method has the beneficial effects that the waste magnesite-chrome bricks are used as raw materials, the effects of environmental protection and production cost reduction can be achieved, and in addition, the self-opening rate of the ladle filler sand prepared from the magnesite-chrome bricks through the process can be greatly improved.

Description

[0001] This application is a divisional application for an invention patent with an application date of July 10, 2015, an application number of 201510415737.4, and an invention title of "A Production Process for Drainage Sand". technical field [0002] The invention belongs to the technical field of pouring equipment manufacturing in the metallurgical industry, and in particular relates to a production process of drainage sand. Background technique [0003] At present, the production process of the drainage sand in the prior art has the problem of not being environmentally friendly. In addition, the produced drainage sand has a low self-opening rate and high cost. Contents of the invention [0004] In view of the above problems in the prior art, the technical problem to be solved by the present invention is to provide a production process of drainage sand with environmental protection, low production cost, and high self-opening rate of the produced drainage sand. [0005] ...
